What does this mean?  In Cisco’s view of the world this means supporting the transport of Fibre Channel, Fibre Channel over Ethernet, iSCSI, NFS and CIFS in a scalable and dependable fashion.

What is the Nexus 4000?

The Nexus 4000 is the 5th release of the Nexus line of switches (counting the UCS 6100 as a release).  This switch fits in the blade center form factor. It is intended to be used in the place of the Catalyst 3000 and 3100 series blade switches. It is a full featured Nexus switch, very similar to it’s big brother the Nexus 5000.

What protocols will it support?

In keeping with Cisco’s vision of a Unified IO platform in the data center the Nexus 4000 will support Converged Enhanced Ethernet (CEE) (yes, they finally caved on the naming) as well as providing the same reliable transport of iSCSI, NFS, and CIFS that you get with the Nexus 5000.

What blade centers will it work with?

Cisco is playing close to the chest announcing what blade server vendors will support this product.

My initial gut reaction was that HP would not be supporting this product, however I just saw that HP is OEM’ing the Nexus 5020. It would make sense that they would support the Nexus 4000 in their C Class blade centers, though only time will tell.

IBM however has been very supportive of integrating Cisco technology, as well as OEM’ing the Nexus 5000 switch in their portfolio. I fully expect the Nexus 4000 to be supported in the IBM BladeCenter platform, though again I cannot confirm.

Dell also has resold Cisco blade switches, and although they do not OEM the nexus 5000 they have been large proponents of the Nexus solution and unification of IO workloads throughout their platforms.

Is it the same as a Fabric Extender?

The Nexus 4000 is not a Fabric Extender. What is the difference? A Fabric Extender is a really efficient multiplexer. While using a Fabric Extender the main goal is vast simplification. What you end up with is a dumbed down remote line card that provides simple, fast services to your access layer. This is great for most uses, however there are instances where you need to provide richer services. A full function switch like the Nexus 4000 is appropriate in this case.

What does it run?

The Nexus 4000 runs NX-OS, Cisco’s data center switching operating system. This is the fourth release of what was previously named SAN-OS which ran on Cisco’s MDS line of SAN switches. This operating system is shared between the Nexus 7000, 5000, 4000, 1000v,UCS Fabric Interconnect and MDS line of SAN switches. Now you can have a consistent operating system platform from your data center core, all the way down through your blade switches and into your virtualization layer.

When will it be available?

Just like when the 3000 and 3100 series blade switches got announced, we are going to have to wait on the individual server manufactures to announce support at their own pace. My gut feel says we will be waiting a couple months for units to get out, and for the vendor certification process to complete. Though with business picking back up, this product may get out sooner.Similar Posts:

Cisco Nexus 4000 Blade Switch

“it looks like one of the key features not on the list of components for the California boxes is going to be a red discount pen”

Timothy references sources who have obtained a price list and shared it with “El Reg” . I wish Timothy would have contacted an actual Cisco Unified Computing System Advanced Technology Partner, because any partner that is involved in the launch could have explained to him the concepts of List price (List), Manufacturers Suggested Retail Price (MSRP), and Purchase or Buy price.

In this article I want to dispel the myths of server and network manufacturer pricing, demonstrate the true cost of building a data center with blade systems, and at the end provide a cost comparison between legacy server vendors options and Cisco’s Unified Compute System.

First, lets go over some the basic concepts of vendor pricing. At the end of this you should understand the difference between list price, manufacturers suggested retail price, and purchase price.

List Price

List price is a high level number that Cisco publishes weekly in its global price list. The purpose of this list price is to provide a uniform price list across all product sets that Cisco offers. The most important thing about list price is NOBODY EVER PAYS LIST PRICE. Let me repeat that again NOBODY EVER PAYS LIST PRICE. Are we clear? This is similar to list price on a car on the car lot. All list price provides is a starting point where a Cisco partner and a customer can negotiate a common discount and end up with something close to (generally at or below depending on technology type and yearly spend) MSRP.

Manufacturers Suggested Retail Price (MSRP)

This concept is something that anyone who has purchased a car before is familiar with. The number that is on the window of the car when you look on the lot is list price. The first number the dealer brings up lower then sticker is MSRP. Depending on the popular of the product, the competition in that particular space, and the negotiating power of the customer you will either pay that price, or some percentage below. For example if you are buying one new car you may have the negotiating power to get the price to drop 5% off of list. If you are buying 200 new cars (say a fleet) you have significantly higher negotiating power, and you may be able to drop the price by 15% of of list price.

In Networking Sales MSRP is significantly less then list price. A good exercise to see what this number is, is to find a device, say a WS-C3560E-12SD-E (3560 with 12 Gig SFP ports and 2 10 Gig ports) in the Global Price List. You have access to this at any partner level at www.cisco.com/dprg . (my point here is that this is no big secret). As of Friday June 12 2009 the LIST price for this product is $19,995.

Now take that same part number - WS-C3560E-12SD-E and pop it into your google search window. Within the top four links I found this product for $12,434.15 . This price is for  pure fulfillment, with no value added consulting or design work from you local Cisco partner.

If you do the quick math, this price difference is equal to 38% off of list price. Come to your own conclusions, but it would be safe to say that this could be considered MSRP for Cisco products.

Purchase / Buy Price

Buy price is just that, the price at which the customer purchases (buys) the product. This is can be at MSRP, or if the customer is buying significant amounts of hardware at a time, or if there is a “special” (programs and incentives) going on the number could be slightly lower then MSRP.

Percent off of list differences between legacy server vendors and networking vendors

This is where the biggest confusion is coming from. Legacy server manufacturers  have set their list prices much closer to MSRP then networking vendors (remember, MSRP is the price where most customers purchase at).

Why is this? In the networking space, vendors have historically created their own processors, ASICS and boards. This means that the sales discussions are feature to feature. It also meant that you had to have a conversation with the networking vendor or networking partner to properly size your network devices and get a quote – which is around MSRP, not List price.

In the legacy server space, especially the majority of the x86 server space, the market has been essentially commoditized. E.G. – You can buy an intel based server with X amount of memory and hard drives that will perform roughly equally from any of the main manufacturers. That made it much easier for a sever admin to just pull a price off of the web and compare. So what the server vendors ended up doing is setting their list price  only slightly above MSRP.

What this translates to is the list price, between legacy compute vendors and Cisco will be drastically unequal. What is equal is MSRP, or the generally accepted purchase price by common customers.

Why did Cisco set the list price of UCS higher then the legacy server manufacturers?

For the vast majority of its sales, Cisco relies on what is called the channel model. This means that Cisco partners with local Value Added Resellers (VAR’s) who sell Cisco’s products and then provide consultative services to design and implement them in customer networks. Most customers who purchase any regular amount of Cisco product either have a general expectation that they will buy Cisco product at a certain percentage discount off of list and sometimes the partner and customer have entered into purchasing contracts which require that all Cisco product is provided at a specific discount off of list price.

If Cisco decided to set the List price at a small percentage lift over MSRP, this would cause a problem for the entire channel. This would be especially hard for any customer who had a contract to buy product at a specific discount. What would happen is contracts would have to be renegotiated, which generally takes months and is about as fun as pulling teeth.

The second reason for setting list price the for compute the same as list for network is quoting. Right now, if you buy hundreds of different Cisco devices through a reseller it is very likely that the discount is going to be the same across all products. This makes the mechanics of sales much simpler, because you don’t have a lot of math in the quote (this can cause errors). On the customer side, having one set discount makes it much easier to compare quotes and to ensure that they are getting the best deal possible. In short, sticking with Cisco’s current list pricing structure benefits both the customer and the partner.

Now that we have set the record straight on list price, MSRP, and Buy price, lets take a deeper dive into what components make up a blade system powered data center. And then we will compare the price structures of both.

Components of all Blade Systems

Blade Server – The compute blade where commodity silicon elements such as the CPU and RAM are housed. As of writing this article, the latest high performance blades from all major server manufactures support two xeon 5500 processors (Nehalem) and DDR3 memory.

Mezzanine cards – These cards take the place of PCI-e cards in a rack form factor server. In a blade system these provide data network and storage network connectivity. They attach to the blade itself via proprietary connectors that implement either PCI-e 8 or 16 lane connectivity at the time of writing. In some cases other functions such as IO accelerators can also be attached in the mezzanine card form factor.

Blade Enclosure – This is functionally a tin can where eight to sixteen blades are placed. It also is used to provide a centralized power distribution fabric, as wells as slots for interconnections of data and storage network devices.

Data Network Modules – These are effectively ethernet switches that have been miniaturized to fit into the tight confines of a blade enclosure. Classically they have provided 1 gig connectivity to the servers, and 10 gig to the distribution layer, however with Nehalem processors and VMware there is a move towards presenting 10 gig connections to the server, and multiple 10 Gig connections into the distribution layer.

Storage Network Modules – The local disk in a blade server is classically anemic. To provide higher IOPS (input outputs per second) to disk, Fibre Channel connectivity is extended by taking SAN fabric switches and miniaturizing them to fit into the blade enclosure.

Data Network Distribution – If you have multiple blade enclosures there is a need to connect them together at a reasonably high bandwidth. To serve that need a variety of 10 Gig distribution switches are provided from all server manufactures at varying cost and performance levels.

Storage Network Distribution – Along the same lines of the data network distribution, SAN fabric switches have to aggregate up to a SAN distribution layer, or if the installation is reasonably large a “director” class SAN switch. This allows all the blade enclosures to see the same storage network, as well as providing for deterministic storage network performance as you scale out.

Management Infrastructure – All manufactures have a need to manage and monitor all of the devices that comprise their blade system. Many manufactures have multiple management modules per blade enclosure.

Comparison of Costs – Cisco vs Legacy Server Manufacturers

The funny thing, is that many people have assumed that Cisco’s Unified Computing System will be priced higher then legacy server manufactures products. In my mind this is because they associate higher quality with higher price (basically the Mercedes vs Kia discussion). Here is something that will shock you - it costs less to buy an entire blade system through Cisco then to buy from the legacy server manufacturers.

When people hear this, they are puzzled. How can two server manufacturers, who buy their CPU’s from the same company (Intel) and their memory from the same fabs end up with different prices? The answer is elegance in engineering. Lets go through each of the elements of a blade system infrastructure and find out where the costs are. More importantly lets look at where Cisco has innovated to provide higher performance at a lower cost.

Dollars and Cents – How much is the cost difference

I worked up two quotes recently. These quotes included all elements required to build an end to end blade system using both legacy server manufactures devices, and using Cisco’s Unified Computing System. I have broken out two scenarios.

8 blade servers - Cisco wins with a savings of 11%

In this scenario the cost of servers and enclosures were fairly equal. The cost savings started racking up as storage and data networking devices were included, as well as base management software was taken into consideration.

320 blade servers - Cisco wins with a savings of 31%

With 32o blade servers the same cost savings seen in the 8 server scenario were amplified. Economies of scale translated into significantly less devices being required to support the individual compute blades. This resulted in 31% savings compared to the legacy server manufacturers.

Summing it up

Cisco has entered into a highly competitive server market by taking an elegant approach to its blade systems. This approach lowers the purchase price of the UCS through reducing the amount of components compared to legacy server manufacturers. I know that there is a lot of misinformation flying around, and I hope this helps to set the record straight on the pricing of Cisco’s Unified Computing System.Similar Posts:

Confusion about Cisco UCS pricing – Setting the Record Straight

The Server Landscape

If you take a look at most enterprise and commercial customers data centers, you will notice a trend of larger fixed workloads running on two rack unit servers (very commonly HP’s DL380), and newer virtualization workloads consolidated onto blade center form factor servers (commonly c7000 class blade systems, and soon Cisco UCS B-Series blades).

However when you go to a remote site where the compute needs are much smaller, you tend to see a few 1 and 2 rack unit system (DL360 or DL380). Why is this? There are a couple reasons, but the most pressing reason is cost. In a blade system, even if you virtualize there is a tipping point where it costs less to install blades and use centralized storage then it costs to use rack form factor servers with local storage. I find that tipping point is generally between five and 8 blades.

If you are a small remote site, or small to medium size business you may not have the compute needs (especially with virtualization) to push you over that tipping point into the blade center form factor. In that case, a few rack optimized servers provide the optimal return on investment for that smaller site.

Taking a closer look at Cisco’s C-Series Servers

Cisco UCS C 200 M1 -

Effectively this is a clone of the B-200 M1 blade in the B series UCS chassis with the addition of two PCIe slots and two more SFF SAS/SATA drives..

The C 200 M1 is a 1 rack unit form factor server (pizza box). It supports a dual port 10 gigabit converged network adapter. two Xeon 5500 series processors, four small form factor SAS drives, 12 dimms for a total of 96 Gigabytes of memory.

Cisco UCS C 210 M1 -

The C 210 is a 2 rack unit form factor server, with the same CPU and memory architecture as the C 200. What has been added is 3 additional PCIe slots (for a total of 5). There is also support for up to 16 SFF SAS/SATA drives.

Out of all the C-Series servers I think this will be the most popular. The extra local disk and PCIe slots will be extremely tempting. For example if this server was populated with 750 Gig SFF SATA drives and augmented with some Fusion-io cards you could have 6 Terabytes of raw disk inside this server. An end user could install Open Filer or iSCSI Enterprise Target and have a pretty respectable NAS head. The other possibility is someone will notice that the Palo adapter can be used as a FCoE target, and use a couple of these as backends for FC storage. (This FC target functionality is mentioned in Silvano Gai’s book).

Cisco UCS C 250 M1 -

Effectively this is a clone of the B-250 M1 blade in the B series UCS chassis with the addition of five PCIe slots and eight SFF SAS/SATA drives.

The C 250 M1 is a 2 rack unit form factor server. It supports a dual port 10 gigabit converged network adapters. two Xeon 5500 series processors, eight small form factor SAS/SATA drives, and 48 dimms for a total of 384 Gigabytes of memory.

This server utilizes the same catalina chipset for memory expansion that it’s cousing the B-250 M1 utilizes.  The ability to aggregate low cost memory plus the PCIe slots to insert solid state I/O acceleration make this a prime candidate to business intelligence / data warehousing workloads as well as Electronic Design Automation.

When can I buy these?

Putting any new product line into production is a monumental effort that many of us take for granted. My gut feel is that Cisco will focus on satisfying demand for the B Series Unified Compute System first, and once manufacturing has hit their stride with the UCS Cisco will start production of the C-Series. In short, I’m  expecting the first C-Series servers to roll off the line at the end of 2009, and  meaningful availability of the C-Series in the first quarter of calendar year 2010.

How do I integrate these into my network?

This is a question that is bound to come up. Cisco’s C-Series servers can integrate directly into your 10 Gig enabled network. Now, to get the best bang for your buck, you should ideally connect these into a pair of Nexus 5000′s to converge your storage and data networks into simple 10 Gig Data Center Ethernet links.

You may however have site without 10 gig enabled switches. In that case, there are multiple PCIe slots in these servers so we should be free to utilize 10/100/1000 adapters. Then when these sites have the need to move to 10 Gig, the server will be capable of supporting that level of connectivity.

My Perspective

At the end of the day, Cisco is now a server manufacture. Just like the HP and IBM, Cisco has to provide platforms that meet customer needs. While the B-Series Unified Computing System is an outstanding platform, it shares similar entry costs that other blade systems have (the need to purchase chassis and interconnects first) which can server as a barrier for smaller server installations. By introducing a 19″ rack form factor line of servers that share many of the I/O and memory benefits of the B-Series servers, Cisco is directly answering the needs it’s customer base by providing a form factor that can scale across all size of customer installation.

Cisco introduces the C-Series Rack Servers

It is truly my pleasure and honor to join Arista Networks as the President and CEO of the company. I have known founders, Andy Bechtolsheim and David Cheriton for a decade and worked with them closely during their Granite/Cisco days. To me, Arista is a symbol of an exciting, innovative silicon valley start-up company at the brink of pioneering new models for cloud networking.

After corporate life and managing multibillion dollars of business at Cisco Systems, you might ask why I chose Arista Networks? Three things really drew me here:

1. A top-notch and talented team, with focus on best of breed products and innovative EOS™ (Extensible Operating System) technology.
2. Working with Andy Bechtolsheim, and our long-standing 20+ year professional kinship.
3. A truly unique opportunity in our industry to build and grow into a great company!

Inside of Cisco Jayshree proved herself as a leader that could get results. There was even speculation that she was tagged to be John Chambers eventual replacement. I have a feeling the same qualities that drove her success inside of Cisco will follow her as she explores this new opportunity.Similar Posts:

The boundary between server team and network team responsibilities has become “fuzzy”

Cisco address’s this issue by putting a switch that can be managed via the same methods common to other network devices inside the ESX cluster. This switch runs the same code that has become standard on Cisco’s Nexus series of Data Center switches – NX-OS.

Prior to adoption of virtualization, when there was a connectivity problem with a host it was quite common for the network team to verify functionality down to the switch port. The server team would do the same. This allowed for each team to focus on areas that met their core competancy. Once we moved from a real switch port, to a dumb bridge inside ESX, lots of finger pointing resulted.

Now, with a Nexus 1000V sitting virtually inside the ESX clusters, the boundary between network and systems teams has been re-estabilished. Now when there is a problem with a host inside an ESX cluster, the network team can use the same day to day troubleshooting tools available to them in other portions of the network to resolve issues faster, and with less finger pointing.

Security controls have been moved further away from the hosts then we would like

A best practice for applying security policy is to apply controls as close to the source as possible. Think of this analogy – Your kids are blasting Radio Disney from their computer. Which of the following do you do?

A. Turn down the speakers at the source

B. Distribute earplugs to all members or the household

Of course, the obvious action is to go to the source, and apply a control (turn down the volume, and tell the kids to clean their rooms). The same principle is valid on the networking side. The best practice is to apply security policies such as VLAN ACL’s and TrustSec policies directly to the switchports that host your switches. Before the Nexus 1000V this was impossible to do in ESX, and forced many environments to move security controls further up into the distribution layer. The side effect of this was that now the security stance from host to host inside ESX clusters was diminished.

The Nexus 1000V brings something called port policies to the table to address this. What these are is pre-configured application security descriptions that are available to you systems administrators to apply in a point and click fashion. Once these policies are applied to the virtualized host, they follow the host where ever it is moved in your virtual cluster.

Provisioning and integrating the networks of VMware ESX clusters with classic networks for most is challenging at best

I wrote an article in march about this specific issue in my post – Challenges integrating VMware into Cisco networks . The core of this issue is that in general that the network integration portions of VMware ESX clusters is not really designed to address server teams , or network teams. In fact, you need to be pretty savy with both portions to successfully integrate VMware clusters into your network. In the real world, you generally find people that are good at one or the other, not both.

By putting a Nexus 1000V in your VMware clusters, you know give the networking teams something they can understand without having to learn Linux, and how it handles bridges (key to understanding ESX networking). With a Cisco switch running virtually inside your clusters, network teams can follow standard core / distribution / access models with the access layer now residing inside the ESX clusters. The network teams can also leverage their existing LAN switching skills for integrating the virtual switches in the clusters with the existing Data Center switching fabrics.

With these roadblocks addressed, Cisco is moving to further the DC 3.0 vision

To realize the DC 3.0 vision, the network inside of VMware clusters had to be under control, and follow the same architectural guidelines that the rest of our network is subject to. With the Nexus 1000V this is now a reality. The next steps withing the DC 3.0 vision to are to extend virtualization and mobility throughout our storage fabrics, and to continue to extend virtualization to the network as a whole, as well as focusing on application virtualization and acceleration to truly realize the vision of cloud computing in the data center.

On the storage virtualization side, Cisco will be using a technology called FlexAttach to enable virtual and physical hosts to change locations in the datacenter without storage team intervention (more on this in a near future post). And on the application virtulization and acceleration side, expect Cisco to continue to enhance it’s existing Application Control Engine (ACE) and Wide Area Application Services (WAAS), and further integrate these into their virtualization offerings.

Cisco releases Nexus 1000V virtual switch for VMware

Dear Candidate:

On August 27, Cisco will introduce a pilot for the CCIE Routing and
Switching lab exam in Beijing, China. The pilot will add a 10-minute
interview that will assess the candidate's ability to apply expert-level
networking skills and knowledge to networking problems that are encountered
on the job. After the lab orientation, a panel of three experts will conduct
a verbal interview with each candidate, asking a series of expert-level
networking questions (questions and answers will be in English). The ability
to correctly answer these questions will affect the exam score. After
completing the interview, the candidate will have the entire 8 hours to
complete the lab portion of the exam.  These scores will then be
calculated and then combined for a total score which will decide a pass
or a fail.

Our goal with this email is to let you know that your day will extend beyond
the normal testing day by approximately one hour.  The additional hour will
be at the end of the day. We hope you find this interview process
enlightening and helpful as we continue to strive for the standard the world
has come to expect from CCIE.

In my opinion this change is both needed and appropriate. In the past couple years, the two main barriers to entry with the CCIE (access to gear, and knowledge) have been lowered with the abundance of training programs as well as dynamips and it’s derivatives for gear emulation. Where in the past you were looking at a minimum of $8,000 dollars for a full lab, now you can run it on your PC at home.

From what I see, this is encouraging engineers to get their CCIE’s earlier in their career. This in itself is not a bad thing. If an engineer has dedicated themselfs to learning all the in’s and out’s of networking technology, then they really have earned the title. The problem comes when people want to take short cuts. They buy a lab of someone in China, or use other methods to get copies of the lab. To them, passing the lab and getting their number is all that is important, not truly becoming an expert in the technology.

While in the short term this may seem like the quick path to a good salary, in the long term everybody loses. Those who have cheated their way to their CCIE (while few and far between) end up devaluing the cert for the rest of us. And at the end of the day, they are just cheating themselves, and will lose their jobs when their true skills are tested.

It looks like Cisco is seeing the same thing that I have just talked about. This pilot program should go a long way into protecting the integrity of the CCIE for years to come.Similar Posts:

Once that button was pushed it was a “now” item. Things like going out, having a beer with the guys, video games, etc all got shut down so my focus could burn a hole in the subject matter.

I just sent in my registration email for the CCDE practical. I’ll be in Chicago Oct 1, ready to give it my all. But, the more important lesson I learned from my CCIE was that if you focus your efforts on your lab day, you will fail. However if you focus your efforts consistently over the months before, you have a chance of passing. Now that my registration email has been sent, it is time to turn that focus dial up, lock to the door to my office and earn the CCDE through months of hard work.

See you in Chicago

NX-OS / DCNM XML API Fundamental Technology

Netconf – platform for secure communication of XML data between DCNM / NX-OS and mgmt station.

XML, using clear text tags, creates a self describing API. This is necessary because of the confusion and unneccessary complexity inherent in the current SNMP MIB based structure commonly in place today.

Webservices API = SOAP/XML over HTTPS.

Netconf/XML on NX-OS capabilities.

• Must be run over SSH
• Maximum of eight concurrent NetConf Sessions per nexus virtual device context.
• Every single CLI capabilities is assigned a XML tag

From Roberts article on networkworld

Ok, so Ethan doesn’t believe in violating the NDA that he had to sign umpteen times to get where he is now, but he’s promoting the use of Testking (a well known cheating tool) to “study” for his CCIE.

As a CCIE, I am obviously supportive of Cisco’s efforts to maintain the integrity of their (and my) certifications. And yes, Ethan was not exercising the best judgment by posting about Testking in a comment on his blog. Is that a reason to start a fire, and try to get his CCIE revoked? As a CCIE, my vote is a resounding no. While Ethan definately made a bonehead move, it does not change a couple things.

1. The CCIE written is just a gating exam, meant to limit the CCIE lab to individuals that have a chance (a notably slim chance) of passing the actual lab.
2. The CCIE exam, and its proctors are amazingly effective at weeding out cheaters. Yes, every once and a while a cheater manages to get through. But trust me, these guys get eaten alive when they look for employment.
3. Cisco has its own enforcement team and methods for finding cheaters, they have managed to keep Cisco certifications from devolving into the land of the MCSE. I think we should trust them to do their jobs, and more importantly trust their discretion.
4. Ethans site documented a very thorough preparation process as he walked the long road towards his CCIE. Sadly his site has been taken down, but in my opinion this shows that he put significant preparation in, and earned his number.

My take on things is that Ethan the target of a marketing scheme. From what I can see, Roberts efforts here are not focused on supporting Cisco’s certifications. It looks to me that he is trying to drum up traffic to his business. If you look at his products, there are $995 – $4,999 fee’s to become a “VIP site”. For your payment, you receive a seal of approval and a listing in the “VIP” area of his site.

Sadly, I have seen this scheme before in the photography world. Certain photographers have been known to set up review sites of other photographers. They build Google Page Rank (PR) on their site so they show up in searches relevant to their competition. Once they start showing up in those targeted searches they sell “VIP” listing or reviews. The photographers that pay up to become “VIP” members ensure that no bad reviews of their buisiness are put up on these sites.

Robert is running the same quasi extortion scheme, but for training vendors. I think this demonstrates a lack of integrity on Roberts part. There is no excuse for attempting to destroy Ethans name in order to make a few bucks. I refuse to condone his behavior and would hope that the editors at Network World feel the same and remove his blog from their site.

Ethan – If you read this, I hope you realize that me and others like me are on your side. You have obviously put stellar effort into both studying, and documenting your efforts. It is obvious to any reasonable person that you have earned the title of CCIE.Similar Posts:

Certguard, Ethan Banks, Network World and Common Sense

When I work with data center infrastructure I expect the following – clean, remotely manageable, secure devices that runs on the same power and similar cabling, and everything can have a 24x7x4 support contract for hardware replacement. For the most part, you get this when dealing with Cisco, HP, Sun and similar manufacturers.

More often then not (with a few very cool exceptions), when I run into video surveillance infrastructure the video management infrastructure runs on some random third tier manufactured server. It never fails that the video management software is on Windows (normally XP or win2k). I have even seen some systems where the vendor requires you to have a session open to run the software.

And then when you get to the encoders themselves, it never fails. You have two choices.

1. The Uber package that can run a Casino, Identify and track dust mites , and if you point it at space, determine if there is life on mars.
2. Individual dinky encoders that run one or two camera’s each. They have limited encoding choices, limited camera control, no remote management, and normally run on 110 volt system that require different power distribution then the 220 that is common in systems today.

Cisco’s answer to this mess

Cisco has released both a video management solution, as well as a video encoding solution in a network module form factor for the Integrated Services Router (ISR).

The first part of this system, the Video Management and Storage System (VMSS) module fills the following roles -

• Management of multiple video streams from one interface, including IP cameras, 3rd party encoders, and streams from Cisco’s video encoding module
• Streaming of live and archived footage through a web browser interface
• This one is pretty cool – The module can mount external storage via iSCSI. So, in addition to its 160 gig internal drive, you can mount a filer and utilize external storage to scale the system.
• “fast forward” to events, as well as notify security and other personnel through SMS and email

The second part of the system (the module on the left in the picture above) is the Analog Video Gateway Network Module (EV-IPVS-16A). It has a couple functions -

• It can take up to 16 analogue video inputs and encode them with MJPEG or MPEG4 codecs
• You can use the first two ports to output video to a external monitors
• If you are using MPEG4, it can be used as a motion detector (handy for fast forwarding to important events, or triggering alerts)
• It can control pan and tilt cameras. This is good for pointing the camera at the janitor unplugging your servers each night to vacuum
• You can configure analogue contacts as an alarm. This can be bound to a door switch, or even temperature and water level monitors in a remote data center. This one will be very handy.

The third part of this solution is Cisco’s Video Surveillance Operations Manager. It manages, archives, displays and distributes the content that was created and collected on the two previous modules. You would use this if you had many branches to aggregate, or needed to staff a video wall (e.g. casino gaming commission operations). Now, you can run each of these components individually. Buy run together as a whole, Cisco has an enterprise class security solution.

Legal implications of a breach

Losing control of personal data means means more then just replacing a tape in your backup rotation. Laws vary from state to state, however generally you are required to contact the identity holders who were breached, as well as fund some sort of remediation. This has huge implications on consumer confidence, and at the end of the day stock price of your company. In some cases, such as ChoicePoint a company can be completely decimated by a breach.

Data protection regulations

There are an ever increasing number of regulations that concern the control of sensitive data. These can vary from laws focused on patient data, to financial data, to personal identification data. The most most well known laws are HIPPA, GLBA, and Sarbanes Oxley (SOX). Past that there are laws that pop up every day at the state and municipality level that further increase the requirements and expense of dealing with a breach. In short, it is becoming an expensive and in some cases criminal offense to lose control of your sensitive.

What you can do to protect your backup tapes

First things first, putting a lock on that Iron Mountain box is just not good enough. You must assume that no matter what, a determined attacker will get physical access to your tapes. So many times companies thing that just because their data format is unique or proprietary that an attacker won’t be able to access it. The cold reality is that any format can be read, and yours is not that special.

The only way to be assured that your data is safe is to encrypt it with a complex cipher. In short, you need to treat your data the same way on tape as you would if it was sitting on a public ftp site (with anonymous access enabled). Luckily Cisco has a technology that allows you to encrypt and decrypt your data coming on and off tape. This technology is storage media encryption.

Cisco Storage Media Encryption (SME)

Cisco’s Storage Media Encryption (SME) technology allows for the seamless encryption of your data flows on and off your backup tapes using AES256 standard encryption. Whether you have VSANS segregating your data, a core / edge architecture, or Virtual Tape Libraries (VTL), you can use SME to protect your data at rest, removing the possibility of an attacker getting access to your critical data.

Storage Media Encryption works by leveraging a multifunction chipset available in the 18/4 module that comes default with the 9222i and is an option for the 9500 series director class SAN switches. Chipset has a couple functions, including line rate encryption of iSCSI and FCIP data streams at gigabit speeds, as well as line rate encryption of data as it streams your tape or virtual tape library’s (VTL).

Encrypting your backup tapes with Cisco Storage Media Encryption (SME)

In the past couple years, VMware has changed from a product hidden in development and testing environments to a full fledged enterprise computing platform. It brings many benefits to the companies that implement it, however with those benefits come changes to the access layer of your data center. Your access layer is no longer a top of rack Cisco switch, or end of row aggregation chassis. It is now a virtual bridge that exists logically within your VMware ESX server.

This causes an interesting question to come up in many customers – Who is responsible for the configuration and maintenance of this Vswitch? At first glance most groups reference the port on the last Cisco switch as the division of responsibility between network operations and systems operations. This has worked well in the past for a three main reasons.

First, it divided responsibilities based on technical skillset. For example a network engineer understands spanning tree, trunking, routing protocols, firewalling. While a systems engineer understands file systems, databases and Linux and Windows operating systems.

Second, it provided for a interconnection point where standardized configurations could be applied by an operational group, versus complicated configurations that could impact overall network designs and require an architectural board review.

Third it provided for a clean hand off for troubleshooting. Both network and systems operations could agree on layer 2-4 functionality in an area that provided for detailed debugging on both sides.

Lack of a defined access layer

VMware ESX throws a wrench in this model. We no longer have this well defined edge at the access layer. The access layer now exists virtually inside a server. More specifically, it is a logical devices running in a Linux server. This presents a challenge because it requires cross over knowledge. Whoever is responsible for this integration has to be fluent in Linux systems administration , and also fluent in network design and operations. Frankly this is a rare skill set to come across, as it requires and engineer who has attained high proficiency in both systems and network engineering.

I see this fuzzy line of demarcation often as a failing point for many VMware integrations. Many times I see network operations teams not involved in ESX cluster design because its a “server” , and systems operations teams generally don’t have the networking skills necessary to design and implement an fully functional system.. The solution to this problem is education and collaboration.

The need for collaborative design sessions

The single most powerful element in a successful VMware integration is the creation of strong design documents. These are created by holding planning sessions where both your systems and networking leads hash out a strong design that takes both short and long term virtualization and network goals into account. Also, many times when people hear the word design, they think it is a high level Visio and a bill of materials. That is a just a fraction of the effort required. A proper design should cover everything from a 10,000 foot overview Visio down to protocol flow diagrams and configuration examples. By created a detailed design like this it is likely to bring up common issues such as 10 gig aggregation, trunking, VMotion security, layer two adjacency and layer 7 network service delivery on a white board instead of a production environment.

To create this detailed design, both your Network and Systems leads have to understand this product. VMware recognizes this is critical to successful implementation (and to further sales of their product) an offers the VMware Certified Professional certification. If you have the resources, I would recommend sending both your network and systems leads to this training at the same time. Having them attend training together allows them to leverage each others strengths and bring up questions specific to their network and their goals.

A real world example of this is the company I work for, Eplus. Last April forty of us, all senior engineers attended VMware Certified Professional training at the same time. The class was mixed up so there was an even distribution of CCIE’s, Systems Experts, and Storage Experts. Needless to say this presented our instructors with some extremely challenging questions, but more importantly it set the stage and created a venue for collaboration between these different practices within our own company.

Real world benefits

A great example of this model’s success this occurred last month. Rick and I were sitting in the engineering side of our Sunnyvale office, catching up on email after giving presentations at Cisco that morning and afternoon. In the bullpen behind us, one of the Microsoft architects was engrossed in a troubleshooting call with a large customer on the other line. It turns out a large systems vendor (who shall remain nameless) had been trying for a week to integrate the first ESX cluster into this network and just could not get the networking portion to work correctly. Our account manager received the call from a the customer, and asked the technical teams to step in to see if we could help out in any way.

The systems engineers were able to isolate the problem down to the network interconnections, but needed to bring in networking resources to resolve the problem. Rick and I were waved over and were given an overview of the problem and introduced us to the customer the far side of the call. We asked a few questions about the physical and logical architecture of their network and created a diagram of their network on the whiteboard. With this we were able to ask them to execute commands continuously isolating the problem domain until we found and resolved the issue.

Seven minutes had passed from the point Rick and I were waved over to the point the customer had a working installation. This allowed the customer to focus on moving their business forward instead of fixing a failed implementation. Three of us on the call had attended VMware Certified Professional training together. We had spent at a minimum 50 hours each creating a baseline of understanding in class, as well as many discussions in engineering meetings. The solution came in seven minutes not because of any one teams individual strengths, but because of collaboration. The systems engineers were able to isolate the problem domain very specifically. And as network engineers trained on VMware were able to quickly understand and digest the issues, and tie it together with our larger understanding of networks as a whole. Only at that point, when the team was able to leverage each others strengths were we able to address the problem so quickly.

There will come a point in the next few years where this fuzzy boundary between the “network” and the “server” is established again. My call is that this will coincide with Cisco finishing development of their Vswitch that will reside inside the ESX server. This switch will require both Cisco and VMware improve their design and integration guides for ESX which are both frankly lacking substance. Until those detailed architecture, integration and troubleshooting guides exist the key to successful ESX cluster implementation will be a strong cross trained systems and network teams that are collaborating on the next level of virtual network design in your enterprise.

Challenges integrating VMware into Cisco networks

IOS-XE is takes the best elements out of Internet Operating System (IOS) which has its roots in a closet at Stanford, and combines them with the most successful open source technology ever – Linux. Cisco is leveraging Linux virtualization technologies such as Kernel Based Virtual Machines to protect against operating system failures as well as to allow for In Service Software Upgrades (ISSU).

To really appreciate this, we first have to dive down into the overall architectural changes of the ASR1000. The largest change that Cisco has made was to implement separate forwarding and control planes. In the past, Cisco routers would have the processes responsible for forwarding traffic, and the processes responsible for configuring the router running on the same root operating system. The side effect of this is that if you want to upgrade the root operating system of your router, you are going to have interrupt the traffic flowing through it to do so, or have a physically separate route processor to take over while you rebooted. This is a big headache operationally, and effectively forced engineers to design in separate physical chassis to meet high uptime requirements.

What Cisco has done to address this, was to mirror changes made in their storage and carrier routing portfolios. Both of those product lines utilize the operating system to push commands into advanced processors that exist on the line cards themselves. The ASICS on the line cards are designed to work in a distributed fashion, so that production traffic never goes into up into the router processor (or sup engine). This in effect ensures that the control and forwarding planes can exist as independent elements.

If you look at the graphic above, you will notice 3 main zones. The upper zone is what we would normally describe as the control plane. This is where the higher level functions such as your routing processes, ssh daemons, snmp daemons, and shells live. In short, if you you configure or read something, you are going to do it here. The only time traffic flows through this plane is when you are doing a thing called process switching. keep in mind this is a rare occurrence and usually occurs because of an oversight in your network designs.

By separating the control and forwarding planes, this allows Cisco to basically run a management station on the router, that programs chip sets in the line cards on the fly. This in my opinion is where the true power of this architecture comes through. By separating the two functions the software engineers are free to utilize powerful open source technologies such as Kernel-based Virtual Machines, and the Linux kernel, while letting the integrated circuit engineers design blazing fast chips which allow full functionality at line rate.

What benefits should we receive from a virtualized control plane? First, in larger routing and switching chassis (including the top end of the ASR1000 line) you normally have physically redundant route processors (RP)/ supervisory engines(SUP). The operating systems on these RP’s synchronize many things, including configuration, process state, routing tables, security associations and much more. The primary reason for this, is if you have a failure in the active RP, you can failover to the standby RP without interrupting traffic flows.They also can be used to streamline the software upgrade process by only upgrading one RP at a time, and then gracefully transferring traffic to it. Once proper operation is verified, the backup RP can be brought up to the same code revision.In any production environment this is highly desirable, and helps immensely in the battle for five nines.

The ASR1000 takes the redundant RP concept seen in high end chassis, and allows you to implement redundant upgrades, as well as protection against software failure, with only one physical route processor. This is done by utilizing Linux kernel virtualization. Instead of running the control plane directly on the production hardware, a small kernel is inserted. Booting from that are two copies of IOS-XE. These run independently, and synchronize state and configurations just as if you had two physically separate route processors. What this means in operational English, is that where in the past, you would have to either have two devices, or a larger device with redundant RP’s to upgrade without disruption, you can now have that same ease of maintenance, in a much smaller (and at the end of the day, less total cost) package.

Below this is the forwarding plane.It plugs into to a high speed interconnected fabric which all line cards and RP’s are redundantly connected to. In the diagram above, this is the bottom level. Items in this plane include buffer memory, Cisco Express Forwarding (CEF) ASICS, and now the new QuantumFlow processor. This is normally where you would find your DCEF enabled line cards, fibre channel and Nexus7000 line cards, as well as the modules for the ASR1000 routers. When properly utilized, traffic should be relatively isolated to this tier, and function independently from the control plane.

The shining star of the ASR1000′s forwarding plane is a group of chips that is referred to as QuantumFlow. The QuantumFlow architecture itself merges Cisco’s strength in integrated circuit design, with its strengths in IOS software design. In the past, Cisco would design ASICS’s for specific functions, and then write commands down into them. This has worked very well, until they point that a new feature came out that couldn’t leverage the fixed configuration of an older ASIC. Your choice at that point was generally to process switch for that feature (which is slower, and honestly bad form), or upgrade your cards to the newer ASIC design. The QuantumFlow chipset approaches this problem from a new angle. The first chip in the set (Popeye) is designed to be field programmable in C, as well as no fixed internal pipelines. This combined with utilizing 40 cores running between 900 and 1200 megahertz allows the programmers to utilize parallel processing techniques to utilize an immense amount of processing power in real time.

To put things into perspective, remember when you got your first multi core laptop or desktop. You were able to say watch a DVD, as well as compile code at this same time, while continuing to have a responsive workstation. Now imagine what you could do with a 40 core processor. This is the kind of power that we are talking about. Now imagine, that not only is your workstation immensely powerful, but you could also offload common jobs such as running daily builds, or encoding videos to another machine (or in this case processor.

In the ASR1000 this processor is called Spinach (yellow are in the graphic above). And of course just like the cartoon, Popeye’s potential really comes to light when combined with Spinach. Spinach is a separate chip, that is used a a traffic manager. This chip handles queueing and quality of service, ensuring that the proper packets arrive at the proper time, as well as interconnecting with cryptographic offload engines so it can equally apply services to encrypted flows.

At the end of the day, the most important question is not how fast something is, or how cool it is. The question is what can it do for me? By leveraging this new architecture the ASR1000 is now able to do line rate inspection of traffic using Network Based Application Recognition (NBAR), Support 128,000 queues for deep quality of service, secure and encrypt data using zone based firewalls and embedded crypto engines, segregate traffic using MPLS, integrate advanced voice and video functionality, as well as providing fulling Netflow v9 support for all of the above. It provides all of these services in an always on solution utilizing Linux virtualization, as well as leveraging an flexible chip set architecture that allows for field programmable improvements in the future.

My hope is that after reading this article that you are in a better to understand how Cisco is leveraging open source technology and integrated circuit designs to improve the foundation of the internet. In upcoming articles I will be discussing design scenarios utilizing this features in this product, as well as highlighting other areas where Cisco is embracing both open source technology, as well as open architectures that can properly leverage projects such as Linux, Ntop, Wireshark and more.

Cisco is using Linux virtualization and 40 core CPU’s for its next generation routers

Mike Writes -

“Hi Colin,
I’m an avid reader of your blog and had a question that I figured you could answer. I don’t have CCIE knowledge like I’m sure a lot of your readers do. I have worked for the same company for 6 years and during that time had been promoted into the Network Group where I was sent through class and earned my CCNA. The company I worked for decided to relocate across the country and so I have been looking for a new job. Finding a new job doesn’t seem to be that big of a deal but I noticed a lot of job descriptions are asking for BGP experience. We didn’t use BGP at my last job and I thought BGP is used primarily by ISPs for routing between Autonomous systems? If that is the case why do so many non-ISP companys list BGP experience in Networking job descriptions? What are they doing with it? Shouldn’t the ISP be doing the BGP routing for them?
Thanks!
-Mike”

Well Mike there are 3 primary reasons why a company would require (or want) BGP knowledge from its candidates.

Scenario 1. The company has an redundant Internet edge.

In this case lets call our company sample_company. Sample_company has its website hosted in a publicly facing DMZ and wants to make sure that its web servers are available in the case of an ISP failure. Normally in this case the company would request and Autonomous Systems Number (ASN) from ARIN and would get assigned a block of publicly routeable IP address’s (normally /24) that they can advertise. Sample_company would then peer with multiple ISP’s for example one connection to AT&T and the other to Sprint. Sample_company would advertise their ASN through both these ISP’s, and in the case of a failure of one of their ISP’s, the rest of the Internet would be able to calculate a path to sample_company’s web servers via the backup ISP.

Scenario 2. The company is utilizing MPLS for its WAN connectivity.

From a customer perspective MPLS is a private BGP based WAN where all edge devices connected to the MPLS provider utilize BGP to inject and learn routes. One note, some providers do support advertisement of routes via OSPF and even EIGRP now, but the most common scenario is to use BGP as your internal WAN protocol while running MPLS. One trend I am starting to notice, is that since companies are already using BGP on the MPLS WAN, they have started utilizing BGP as their primary routing protocol for their sites to avoid running multiple routing protocols and having to redistribute into BGP to cross the WAN.

Scenario 3. The company is using MPLS inside their data centers for segregation of business units.

In essence they are using the same tools and technologies that MPLS service providers are, however applying it inside of their data center and campus networks. In this case, BGP is the routing protocol necessary to carry the routes between the seperate MPLS VPN’s that are running inside the corporate data center. While this sounds pretty complicated, it actually simplifies many of the designs that you would normally implement to attain the same goals.

Learn more about BGP - Of course, there are many other reasons why you may see BGP on a job listing, but I think the previous covers the most common. If you are curious, and want to learn more about BGP I recommend buying Routing TCP/IP volume 2 by Jeff Doyle. This covers many great scenarios and configuration examples in EGP protocols. It is also written in plain English which can be a challenge with many technical books.

Learn more about MPLS in the enterprise - If you are feeling like learning about how you can implement MPLS inside of your own enterprise network then I would recommend buying Network Virtualization by Kumar Reddy and Victor Moreno. I was lucky enough to have Rick Davis translate the whole idea of utilizing MPLS in a campus environment into plain English for me a couple years back. From that point I was able to really expand my knowledge base and start asking the right questions from a firm foundational understanding of the technology. Kumar and Victors book took my understanding to the next level, showing how to incorporate many very cool features to make a MPLS network stand on its head if you want to. I can say (and actually have said to Kumar Reddy) that this book redefined my data center designs for large corporate and enterprise customers. I really recommend that you add this to your collection.Similar Posts:

Reader question – Why are corporations looking for BGP experience?

What useability enhancements do you feel are the most beneficial?

1. A separate, IP enabled, Management Interface. This has been a long time coming. The out of band management interface is very similar to a Ilo card in the HP world. it is effectively a supercharged console server that happens to site on the backplane of the sup engine. I am sure whoever pushed this feature through is going to get flowers one day from a Tech who DIDN’T lock himself out because the management interface was effectively a separate system.
2. Finally, a functionally USB Interface that I can transfer IOS (well, now NX-OS) images through. Everyone has a USB key nowadays, even my Grandmother has one, it will make life so much easier when I can have a 4 gig key with me that has most IOS / NX-OS  versions and my common configs and just pop them right in.
3. The integrated Cabling system is CLEAN. I love that it forces you to reserve the appropriate space for cabling, and that there finally is the possibility to avoid the flying spaghetti train wreck we see so often in Data Centers.
4. Front to back Cooling. The cooling design is well thought out. I liked the fact that it draws from directly above the front floor and exits rear top.. This should help out in raised floor data centers that have a large temperature gradient as you move to the top of the rack. It also negates problem of having multiple 6500 chassis side to side and having warm air blowing from the exhaust of one 6500 to the intake of another 6500.
5. Fan Slots are now placed where it is IMPOSSIBLE to cover with cables. I would say 7 out of 10 times when I walk into a new customers Data Center I find that there are cables run directly over the fan tray with no slack. That is not a failure in design per say, but it could have been avoided. With the Nexus 7000 fan trays in the back the problem is solved before it is created.
6. Power supplies are in the back . FAR away from the data cabling. It never fails that 20 amp circuits get uncomfortably close to copper cabling. By moving the power supplies to the back side of the chassis, this becomes a mute point and we remove any shadow of a doubt about EM interference causing craziness in our cabling.
7. This one sounds really mundane, but a quick heads up grouping of status lights. In the past these were normally in a position where you had to squat down to see them, or they are obscured by cables. Buy putting them on the front of the cable tray assembly it ensures these will always be visible.

What can we focus on now to make it a better platform?

1. One thing that worried me a little was the placement of the compact flash cards in the supervisory module. For those how haven’t it up close look at this picture of the chassis  and look for the Grey cover midway up the sup modules in the center slots. Behind them are two flash cards, one for system partition extension, and one to dump log files into. Having these cards available are great features however I could see an operational process of security rotating out the log partitions, or more likely and engineer pulling the flash card after dumping some data for analysis to it, and then pulling the wrong card by accident. Having a simple strap (like the screw downs for power supply plugs) or something similar would go along way towards mitigating that risk.
2. Continue with the spirit of innovation that has defined Cisco over the years. Cisco has consistently came out with or acquired and integrated many great products that directly address the needs of the market place into the product line (MARS, ASA, AireSpace, TelePresence, MDS, ACE, Etc) but frankly the last GAME CHANGING product that set the industry on its heals and forced everyone to rethink how we utilize technology to accelerate business as a whole was the acquisition of Selsius and the introduction of VOIP as an enterprise class product to the world. I remember having the hair stand up on my arms from the excitement of going up against Avaya and Nortel back then and fighting that uphill battle, educating customers and peers about this “new thing called VOIP and how CallManager (now Unified Communications Manager) is your ticket towards productivity.

   When we talk about the Virtual DataCenter, I/O Virtualization (FCOE) and VFrame Automation it is not just another incremental improvement of existing technology. It is a paradigm shift, a leap ahead, a GAME CHANGER. I get the same chills that I did when VOIP was new because I know that those are technologies that will force us to rethink how we approach computing and data systems. These technologies are to the Data Center what IP telephony was to the PBX, and Cisco is the only company with technologies and engineering know how in all the verticals necessary to pull this off.

DataCenter SVP Jayshree Ullal interviewed about the Nexus 7000

One feature that is new, and frankly extremely exciting is Virtual Device Contexts. Each virtual device runs with its own process, vs the use of tagged differentiators in technologies such as VRF-Lite. This provides for paravirtualized management instances, and clear lines of delineation for both software and hardware for a resource that can be shared between different groups within an enterprise.

Chassis that run NX-OS will support In Service Software Upgrades (NSSU) to allow operations groups to upgrade operating systems with zero downtime. This is accomplished through a combination of modular software architecture, and the decoupling for the control and forwarding planes.

One of my favorite features in SAN-OS is the embedded is fabric analyser. This is a tool that can sniff management traffic without having to plug in a sniffer, or provision a span port. You can dump in real time to a tcpdump like interface in the command line, output to a local file, or map to the ip of a wireshark instance that layer 3 access to the management port. Cisco again has taken the best of SAN-OS and bundled it with NX-OS. You will be able to remotely span management traffic without having to set up rspan, or trudge down to the datacenter to set up a sniffer.

Now, your router can call home right now so that is not a totally new feature. Smart Call Home was released recently into IOS. But that still doesn’t stop it from being a great feature. This allows you to configure NX-OS powered devices to mail an xml formatted troubleshooting email to TAC, and / or your support staff. This has been proven to drop the average time to resolution from 16-30 hours to 6 hours.

Now the drum roll…… All IP routing features are VRF aware. This has been a point of contention with me for a while. As Cisco and the market in general has embraced virtualization as an answer to pressing business concerns of leveraging shared infrastructure, while retaining security controls segregating disparate environments technologies such as MPLS and VRF within the datacenter have become more and more prevalent. That is great, however it never fails that the feature you need at that moment always seems to be coming out in the NEXT IOS release. With Cisco NX-OS 4.0 this is no longer a question.

Now, if I was a CIO and I was reading about all these new technologies that Cisco was pushing with NX-OS, I would frankly be cautious, and rightfully so. The thing is, most of these features are not new, they have been in use, and in production under the most stringent uptime conditions in the world – storage networking. They have been tried and tested on Cisco’s MDS line of storage networking switches. So get comfortable, get educated, but most importantly get on board for DataCenter 3.0.Similar Posts:

Quite possibly the funniest and most educational PhotoShop tutorials ever.

For the engineering perspective on this, the CCDE is equivalent  to the CCIE. However, the CCDE is focused on design and architecture rather then implementation. Where the CCIE (R&S, Voice, Security, Service Provider, Storage) is focused on implementation, the CCDE is focused more on the pre-sales design and architecture efforts. I am personally looking forward to the lab being released, as it provides a certification to validate the skill set needed to be an sales engineer on Enterprise accounts, or to be a network architect at an Enterprise corporation.

It is funny how small a world it is. Eplus (the company I work for) CEO – Phil Norton was quoted on Cisco’s press release -

“Certifications provide a stamp of approval that validates the quality of our organization’s employees,” said Phil Norton, chairman, CEO and president of ePlus. “The CCDE isn’t about operations; it’s about recognizing the value of network designers and honoring their core skills that provide a real value to our business and our customers.”

My gut feel when I first got invited to the CCDE beta program was that this will become a requirement for the Channel. I think Phil’s statement cements that gut feel into a reality. Obtaining a CCDE will become similar to the CCIE – a check box that you must attain to work with the top VAR’s out there. This makes me extremely grateful that I was lucky enough to be invited into the beta group to be allowed first crack at this gem of a certification.Similar Posts:

About Colin McNamara

This tactic address one key failing of ISCSI. Specifically an ISCSI interface running at 400 megabit will take 16% of a 3 ghz 64 bit cpu while using a software initiator or target. This can create some interesting issues where you don’t want to have them. By removing the layer3 information, and transposing fibre channel commands over the Ethernet transport a major cpu hit is avoided.

My gut feel is that this technology will follow a similar track as ISCSI did. ISCSI had a very low adoption in the first 3 years. Storage guys are naturally timid, as there are stiff consequences for failure, but eventually engineers warmed up to ISCSI and started deploying it where it was most appropriate, in lower bandwidth utilization hosts. FCOE will follow this same path, however this time we won’t have to fight the FUD of storage of a network transport. What is in FCOE’s favor is that as a protocol it is optimized for the general ISCSI setup of flat layer two transport between target and initiator.

That all being said, we are going to have to see some product releases from Cisco and Intel for FCOE to really take off. If we don’t, then FCOE will fall down the same hole that ATA over Ethernet disappeared down.

Cool new features in 12.4(15)T

My background is all over the place. It goes from running a small ISP when I was 18 to managing international CallManager clusters, to enterprise data center design and migrations. I swear that I have tech ADD. I see something new and I am like.. oooooh shiny, lets do a sniff and see how it works.

I actually attempted the Route Switch lab twice in 2002 (still had token ring and dlsw still) but got activated for the war before I could get my number. I can tell you.. that sucked horribly.

So, why did I choose to get my Storage CCIE first instead of finishing up my Route Switch first? Well, over the past couple years I have done a significant amount of IP storage (NFS, ISCSI, ATA over Ethernet, etc) including building my own IP storage heads based on linux. I had also done a little bit of fiber channel work. I felt that I had a significant advantage compared to most network engineers in the storage networking space. And, I think more importantly, the topics that I had to study were new and fresh. Whereas when I cracked open my Route Switch books.. I honestly wasn’t to excited about it at the time ( I think I was holding a grudge from my first attempts in 2002).

The partner e-learning central portion of Cisco has an Excellent lab access to labgear.net. It gives you 2 hour segments of time with 2 mds’s (both with IPS blades), 1 2 port jbod, and 2 2 port servers. They also have introductory tutorials for most major technology segments.

I did all of those, along with the every E-learning class that was on PEC. I think the major ones were the Design, Support, and CASSI classes.I took that, sat for the design and support specialist exams, and took my written last December.

After doing all that work, I was honestly 70% there. I took a little break for january and febuary (There was no open lab dates) and then started hitting the labs I think at the end of febuary.

For the majority of my practice I used the labs available through PEC. I also was able to weasel my way into 8 hour sessions every sunday from our channel SE. (I owe him plenty of drinks at networkers this year) For those 8 hour sessions I had labs created to summarize the major technology areas and to be as evil as possible to myself.

I had one attempt which didn’t work out as well as I would have liked. In RTP the lab starts at 7:15. This means if you are from the west coast like I am you will be getting up at 3:00 am in the morning for your lab. That royally kicked my but. I diverted from my attack plan and ended up
running out of time. It was a classic example of letting the lab run you, instead of you running the lab.

Luckily a data opened up just over a month later. I spent that time just working on my speed (speed is the secret sauce). I migrated to using Fabric Manager (gui interface) instead of command line. After 2 practice runs my time had dropped 25%. I also flew out to RTP 3 days before, and made sure to relax and get on east coast time.

For my final prep I got access to iementor’s lab. Their lab is excellent. I cannot reinforce enough how much it contributed to my confidence in that final week. Roman was really cool about working with an existing candidate to get me squeezed in. They are really cool guys, and they have the only workbook on the market right now.

So, I used their lab 2 days before mine, and then just chilled the day before. The day of the lab I had 70 points by lunch, and had completed configuration of the lab by 12:30. I spent the rest of the day reviewing my configurations (found 2 errors), fixing one bug, and generally harassing the proctor to make sure I didn’t misinterpret anything.

So.. if I had it all to do over again what would I do. I would still do the PEC stuff, and continue to primarily live in the Doc CD. Though I would probably pony up the cash and buy the iementor book and more lab time with them.

Why was Storage Networking my first CCIE? And What did I do to prepare?

For those who haven’t heard yet, I passed my CCIE Lab on June 14th. Now I can officially put CCIE #18233 after my name.

Anyone who has been down the same path understands how long of a road this is.
I started down this path in the spring of 1999 as the 432nd student ever in Cisco’s Networking Academy (which I promptly dropped out of to move to the bay area). I grew my networking skills all the way to passing my CCIE Written in 2001. I attempted my Route Switch lab in 2002, however I got called away to war for a year. Being away from it all for a year really cramped my style technically. In that time many of my certs expired, and I lost much of the momentum I had built of the past half decade.

Since I got back to the real world I had focused on work to the detriment of my certifications. I really did some great things, however I really neglected my resume.
In July of 2006 I had worked 2038 hours that year (for those not mathematically inclined, that is a full work year, in 1/2 a year) . At that point I decided it was time to stop neglecting my certifications. At that point I dedicated 8 hours each saturday, along with two nights a week to studies. By December of that year I had Certified on a few of the technologies that I had tons of experience in.

I managed to get my RHCE, Cisco Storage Support and Design Specialist, update my old IP Telephony specialist certifications to CCVP, get my Netapp Certified Administrator, and pass my CCIE Written for storage networking all by the end of the year. This spring I finished my Netapp Certified Expert and scheduled my Storage lab for early summer.

Anyone who knows me well knows how closely I track my time. That time tracking extends to my training. I tracked my training (reading, lab practice, testing, etc) just like any other part of my professional life. I spent around 150 hours studying for my Design, Support specialist certs, along with reading the recommended books of the CCIE reading list, and around 300 hours preparing for my lab exam. That is 300 hours configuring every possible combination and permutation of technology that could be setup, and then refining my speed in configuring those technologies until i got to the point where speed as well as brains would be an advantage in the lab.

So now that I have my CCIE, whats next? Well, oddly enough.. I am thinking of getting my second CCIE cert. In my office I will be the Jr guy by only having a single CCIE (on of our guys has all five). I also need to take my VMware certified professional cert, and probably get my HP Master Accredited Storage Engineer. I guess I am just a glutton for punishment.

What does it take to pass the CCIE exam?

Put Yourself at the Center of the Action

The rules for marketing a conference like our Web 2.0 event are pretty much the same as those for marketing anything else. Here are the ones we follow.

1. Be first. This is one of the immutable laws of marketing. Who was the first person to fly across the Atlantic? Lindbergh. Who was the second? No idea.

2. If you can’t be first, create a new category so you can be first. Who was the first woman to fly across the Atlantic? Amelia Earhart. New category. We didn’t have the first Web conference out there, but when we applied “Web 2.0″ to the category, we created something new.

3. Position yourself at the leading edge of a new wave. The way to make sure you recognize the next big wave is by watching what I call the alpha geeks. You find people who are cool, by whatever metric you want to apply. It would be the same thing if you were marketing sneakers. And then you find out what the cool people are doing and you spread the word about it. This isn’t to say there aren’t audiences for whom cool might not be the right measurement, but it works for us.

4. Tell a big story. We don’t market products narrowly. We market big stories about the industry, things that matter to a lot of people. In 1992 we came out with The Whole Internet User’s Guide and Catalog. Instead of marketing the book, we marketed the Internet using the book, and said the Internet is coming and by the way here’s a book where you can learn about it. In planning Web 2.0 in 2003, we came up with a goal to reignite enthusiasm in the computer industry. We said, here’s something that distinguishes the companies that survived the dotcom bust, here is something that is bubbling up again, so we gave it a name – Web 2.0 – and started telling a story about what was new and important in technology. Sometimes giving it a name helps people to see it.

5. Make it an A-list party. Conferences are really like parties, and an A-list party is one where A-list people are in attendance. You figure out who are the really important people to invite and get them to show up as speakers or as guests. Then everybody wants to be there. If you don’t know who the important people are, you shouldn’t be doing a conference.

6. Care about the attendees. There are a lot of lousy conferences that pander to sponsors. They end up creating an opportunity for boring speakers who are paid shills for their companies. We still get a few of those, but we really try to police it. Think about who the audience is and what works for them, and deliver high-quality content.

How to succede in 2007 – By Tim O’Reilly

2. Update the Real Time System config generator

Existing Features-
Generates Content Switching configs from application data
Has a web interface for development access
Notifies help desk
New Features -
Create firewall definition files
Create nagios probe config
Integrate XML submission probe generation
Thoughts
Nice to have, but 90% of the functionality is already there

3. Update Nagios system config generator (nagiosuploader)

Existing Features-
Grabs system info when run locally
Posts configs to monitoring server for processing
New features
Host auditing to determine services monitored
Clean up error condition handling
Web interface for config generation
Thoughts
Having a web interface for users to fill out would lower my workload

4. Automate web application error reporting

Existing features -
None, well.. manually executed text processing on log files. I wouldn’t call that an application
New features -
Automation of customer / error code matrix grep statements
Output in XML / http format web page and email
Text only output in commented form <– text –> for command line mail clients
Thoughts -
Proves the point that certain people can be replaced by very small shell scripts (Unix humor)
Should be a big with with Client services
Could drive the application “digital dashboard”
Should be a fun to practice using AWK for formatting data in a standard output
Serious danger of scope creep
May be better implemented in a MySQL back-end

5. Do some personal growth items

Finish the Vmware image for the 7206 emulator and post to Vmware Technology Network for general use (delete IOS files before uploading)
Read some more of Long’s storage book
Write a sample chapter for Stay at Home Photography
Get GTK pod to run under my cmcnamar account, not root (I think the IPOD’s file system doesn’t like changing ownership or file attributes)
Redo the 2cups homepage
Clean the Garage……..
