VBlock Infrastructure Packages

VBlock infrastructure packages are pre-configured bundles that are sized to support specific workloads. These packages are available to run both on the customer site, as well as in a hosted (cloud) facility. If you have been listening to anything that has come out of VMware in the past couple years, it has been centered around the unification of private and public clouds. VBlock is a building block of this integrated cloud.

The VBlock infrastructure packages are offered in “bundles”. These bundles are numbered 0-2 at the time of writing.

VBlock 0 is an entry level package supporting 300-800 virtual machines. This is built on Cisco UCS, EMC Celerra Unified Storage, VMware vSphere and the Nexus 1000v.

VBlock 1 is a mid level package supporting 800 – 3000 virtual machines. This is built on Cisco UCS, Cisco MDS, EMC Clarion, VMware vSphere and the Nexus 1000V

Vblock 2 is a high end package supporting 3000 – 6000 virtual machines. This is buit on Cisco UCS, Cisco MDS, EMC Symmetrix V-Max, VMware vSphere and the Nexus 1000V

Integrated Pre-Sales, Service and Support – Fighting the skill silo

The defining factor in the successfully sales and deployment of virtualization infrastructure has been cross platform knowledge and experience. Storage, Network, and Virtualization vendors, as well as partners have struggled to attract and train engineering and sales forces with this cross functional skillset. Partners who have engineering teams with skills that cross these functional areas have seen success even in this down economy. Cisco EMC and VMware are smart enough to recognize this trend and have linked sales teams at the hips in engagements. Nothing makes this more apparent than John Chambers himself addressing Field Sales in the VCE webcast and requiring that these teams coordinate and act as one cohesive unit.

Acadia

Cisco, EMC and VMware have jointly funded a venture called Acadia. This venture, initially staffed at 120 employees is charted with the development and validation of cross platform solutions. They are focused on a “build operate transfer” model for service providers and large enterprise customers. The target date for Acadia’s launch is Q1 2010.

Partner Ecosystem

This was my biggest worry about this release. Does Cisco, VMware and EMC funding Acadia mean that they are going to go direct and bypass their channel? The party line is no, that all three partners will still utilize the channel to sell and distribute the VBlocks. An interesting new twist however is that there is not one master partner certification to sell “validated” VBlock solutions. To participate a partner has to be certified at reasonably high levels with all three partners to have the ability to register and sell deals under the VBlock mantra.

What hasn’t been clearly answered is what happens when a workload is moved to the “cloud”. Does that go through the channel? What if that cloud infrastructure is built onsite but maintained by Acadia? It sounds like we have to wait till January 2010 to get that answer. In the end time will tell whether Cisco will hold true to the success they have found in the channel, or whether Cisco will end up in an MBA case study of what not to do.

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

He writes about “the VLAN leaking myth” and how it encourages clients to utilize physically separate network infrastructure in the DMZ’s. Now first things first, I wouldn’t call VLAN leaking a myth. At one time it was a very real and serious vulnerability that was exploited by overflowing the capacity of the switch you were attacking, and causing it to “downgrade” from switch to a hub. Once this happened you now had access to previously protected devices, as well as having the ability to sniff data as it passed through the shared hub backplane.

As he mentions though, this is 8 years ago. Most switches have evolved to the point where backplanes far exceed the traffic that could ever be injected into their switchports. Even beyond backplane enhancements there are many ways to further firm up your security stance – Virtual Device Contexts, not using Layer 3 SVI’s on a DMZ VLAN, utilizing PVLANs, using port security, virtual routing instances, and many more. Of course, there are still many other attack vectors that still remain, but can be mitigated by utilizing features built into the majority of enterprise switches available today.

I think the real question is not “are VLANs safe in a DMZ”. The important question is have you mitigated the probability of compromise (the actual threat) to levels that are acceptable to your business. This question remains whether you have a standalone switch or not. So many times we hear about risk risk and more risk. But risk alone is meaningless in a business context. What is important is combining risk with likelihood. For that I like to use a simple table to come up with the true threat.

For example, as I drive to Fry’s there is the risk of me dying due to a car crash. The impact of me dying is very high (risk) however the likelihood of an accident is low, and furthermore I reduce (mitigate) the latent risk (threat) by wearing my seat belt. So all in all the threat of me dying on my way to Fry’s is pretty darn low.

In a business context this may be that I have public facing web servers and network devices in my DMZ. The impact of them being compromised is that my public image may be tarnished for a short time, and my end users may lose productivity if they are not able to VPN into work, or access the Internet while on premise. I mitigate this risk by using firewalls and both host and network based Intrusion Prevention Systems as well as implementing best security practices on my network and systems devices. The latent risk (threat) remaining is at a level that is acceptable to the business leaders, so the system is allowed.

One question that I have seen coming up more often as we move towards fully virtualized data centers is centered around commingling of virtual infrastructure. There are some hard questions which challenge some practices that we have held true over the years.

• Should you allow sharing of physical memory on a host virtual machine between an internal and DMZ server?
• Should you allow virtual infrastructure from multiple security zones to share a storage array or cluster of arrays?
• Should you allow multiple virtual switches in different security zones commingling on the same ESX or Hyper-V cluster?
• Should you allow virtual firewall and load balancing instances protecting internal and external zones to reside on the same hardware?
• Should you allow virtual routing instances from multiple zones to share a physical infrastructure?

In the past world of standalone systems, the additional cost of providing a wholly separate infrastructure for DMZ environments was relatively low. Each system generally had internal disk, or at most direct attached storage. Network devices themselves were scaled down to support one chassis one function. This fit quite neatly into the Enterprise Composite Network model that was quite common from 1999-2003.

Now, many data centers have moved to the Service Oriented Network Architecture (SONA). In this model the cost of a virtualized data center is primarily focused on foundation elements such as the virtual storage and virtual fabrics, virtualized network, and virtual systems elements. The cost of providing additional virtualized services off these elements is low, however the cost of duplicating the physical infrastructure is quite high on both the capital and operational levels. This is forcing the technical and executive leadership at many companies to take a long hard look at the true threats they are facing in previously physically separate security zones such as DMZ’s, Financial and other secure zones. In the end, they are having to decide whether the threat remaining after their security controls is worth duplicating hundreds of thousands of dollars worth of infrastructure or not.

These are hard questions, with really no single good answer. My gut feel is that over the next few years we will continue the move towards the fully virtualized data center where components such as memory, PCI-X buses, storage and network devices are even further decentralized. This will make the cost of duplicating the infrastructure more and more significant, causing consolidated data center (or compute) fabrics to be the norm. At this point the discussion will move away from securing zones by creating separate infrastructure, to providing end to end security, starting integrated application level security, maybe with TrustSec or a dirivative, all the way down to securing the data at rest on disk. For the time being however, the best we can do is sit down and do an honest appraisel of our security stances, mitigate what we can, and do our best to design data center architectures that provide the flexibility of implementing whatever choice the technical and business leaders agree on.Similar Posts:

Darrel Hinshaw – New Triple CCIE [Storage]!!!!!!!

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.

Simplifying remote site security with Cisco’s new video surveillance modules on the ISR

1. Layer 2 Tunneling Protcol (V3) static and hairpin configuration example - my buddy Rick was nerding it out in the lab and sent a great configuration doc for L2TPv3 my way. L2TP(V3) is used to create a layer 2 psuedowire across layer 3 routed links. This is a great service provider tool that you can use in your own network, no MPLS needed .

2. SNIA Education – Fiber Channel Over Ethernet – There is a lot of buzz going around right now about Fiber Channel Over Ethernet (FCOE). There is also a lot of misunderstanding about the fundamentals of this architecture. This Storage Networking Industry Association (SNIA) does an outstanding job of covering FCOE at both at an architectural level, as well as going over low level messaging structures.

3. Trill (Rbridge) architecture – IETF internet draft – I think the last time I was this interested in an internet draft was when iSCSI was first being proposed in the IP Storage working group. Trill, in my opinion is basically a light weight version of MPLS / VPLS. It has as far as I can tell most of the advantages of this architecture, without some of the configuration and hardware requirement drawbacks. Fair warning, reading this document started a doc hunt that killed my Saturday.

4. Cisco’s Security Response to Sebastian Muniz’s IOS rootkit – Security is a very important aspect of network design. Sebastian’s IOS rootkit demonstration is going to force some customers who in the past have been “OK” with having older, possibly vulnerable IOS versions floating around to update their operational practices and start keeping their routers and switches operating systems as often as they do their servers. Thankfully, Cisco has been embracing technologies such as kernel virtual machines, in service software upgrades and more to lesson or remove the impacts of software upgrades.

5. Turning Wounded Warriors into Network Ninja’s – As a former Marine (well, always a Marine, formerly employed by the USMC) this program goes straight to the heart. Cisco is partnering with Naval Medical Center San Diego (NMCSD, or Balboa Naval Hospital for us locals) to provide technical training to Marines and Sailors who have recieved service ending wounds in Afghanastan and Iraq.Similar Posts:

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)

This switch answers a fundamental problem that has been presented by blade centers and VMware. The problem is increasing density of 10 Gig Ethernet, as well as the creation of SAN islands to provide storage access to VMware ESX clusters.  The nexus 5020 provides a solution that address both of these challenges, as well as supporting Fibre Channel Over Ethernet (FCOE) for the eventual move to a consolidated data center fabric in the years to come.

Nexus 5020 – Consolidated 10 Gig Ethernet and 4 Gig Fibre Channel

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. If this article has you interested in learning more about some of the technologies mentioned today, then I encourage you to check out some of the links below, or shoot me and email to be highlighted in a future readers questions article.

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:

Cisco NX-OS 4.0 | Next Generation Internet Operating System

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.

As initially discovered last month, VMware will make available a special version of ESX Server (mentioned with terms like ESX Lite and Embedded ESX) for OEM vendors, to be installed into bootable Solid State storage devices (flash drives, etc.). This option will allow creation of ESX Server hardware appliances for easy jumpstart, granting smaller form-factors and improved reliability.
Dell, IBM and possibly other vendors will offer this option at announcement time in Q3 2007.
* DMotion
Unofficially introduced with ESX Server 3.0.1, in its first version DMotion is a special VMotion operation only capable of moving running virtual machines from an ESX Server 2.5.x host to a new ESX Server 3.x., without shared SAN LUN mandatory requirement.
In ESX Server 3.1 this capability will be extended, allowing hot migration of running virtual machines between ESX 3.1 hosts through the Ethernet cable.
* Patch management system for host and virtual machines (Update Manager 1.0)
ESX Server 3.1 will finally introduce an automated patch management system called Update Manager. This solution will be able to update both host itself and virtual machines (both Microsoft Windows and Red Hat Enterprise Linux).
Update Manager will look for available updates from Shavlik Technologies website (a possible acquisition after IPO), and will allow VI administrators to decide which patches to deliver to virtual machines.
Before applying them, Update Manager will take a snapshot and will even rollback automatically if something goes wrong.

(this product was originally codenamed VM Integrity and its developement started more than one year ago, when virtualization.info discovered it in June 2006)
* VMware Consolidate Backup (VCB) and VMware Converter 4.0 integration
VirtualCenter 2.1 will now allow restoring VCB images with an integrated version of VMware Converter, which reaches 4.0 release number.
* Server consolidation advisor
VirtualCenter 2.1 will expose a server consolidation assistant able to analyze which physical machines should be converted in virtual ones, and where to move existing VMs among available hosts.
(note that with this feature VMware is further extending competition with PlateSpin, covering both features with PowerRecon and PowerConvert)
* Guest OS disaster recovery capability
VirtualCenter 2.1 will be able to recognize a failure inside a virtual machine and restart it through VMware HA module.
* Support for VMware Server 2.0
VirtualCenter 2.1 will be finally able to seamless manage both ESX Server and VMware Server 2.0 hosts.
* Lockdown Mode
ESX Server 3.1 will expose a new security feature to completely disable local administrative account after a VirtualCenter 2.1 takes remote control.
* Power saving capability (Distributed Power Management)
VirtualCenter 2.1 will introduce a new resources utilization analysis feature, able to verify when a physical host can be powered off, VMotion-ing its virtual machines on other hosts without impacting performances.
* Support for Cisco Discovery Protocol (CDP)
VirtualCenter 2.1 will be able to recognize and use CDP to discover physical and virtual network topologies.
It stays unconfirmed if ESX Server 3.1 will already expose new virtual network architecture, allowing 3rd party virtual switches, as it will be announced by Cisco CEO at VMworld 2007.
* Support for 10Gbit Ethernet network cards
* Support for TCP/IP Offload Engine (TOE) network cards
* Support for network load balancing algorithms
* Support for 200 hosts and 2000 virtual machines
* Support for 128GB RAM per host and for 64GB RAM per virtual machine
* Support for SATA storage devices
* Support for N_Port ID Virtualization (NPIV)
* Support for VCB over iSCSI SANs
* Support for IPv6 in virtual networking
* Support for Para-virtualization guest OSes

New features in VMware 3.1

For those that have been watching, there has been a trend of helpful MDS (Cisco’s director class storage switch) features into core networking products. The first feature I have noticed is the “do” command now available in configuraiton mode in ios 12.4. It allows you to execute exec commands from the configuration section in IOS. Needless to say this is very handy, primarily due to not having to exit to your shell to do a show command.

Things like that make me very happy. They decrease the time needed complete tasks, and improve your accuracy.

One of the features that I have always loved with the MDS is call home. It is a deamon that monitors the hardware and software for faults, and when one is found it posts an email to TAC and your support staff.

This feature now has made it into the 6500 series switches as of 12.2(22)SXH which should be out mid August. It will integrate directly with Cisco TAC, and your own internal Monitoring and management systems. The really cool thing is that this ties right into the GOLD (Generic On Line Diagnostics) tests. If your GOLD tests find a hardware problem TAC will automatically be contacted, a RMA issued, engineer contacted, and parts shipped to the devices location. The target for this is SmartNet time + 1.5 hours. So if you had 4 hour smartnet, you could expect hardware onsite, with no additional troubleshooting in 5.5 hours.

Cisco portal for smartcall is located at http://www.cisco.com/go/smartcall

The emergence of MDS features in Cisco’s datacenter networking equipment

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?

The first lesson was that knowledge alone is not suffient to pass the lab.
The second was that the lab is not the real world, and the procotors do not intend to replicate real world problems.
The third lesson was that speed is as important as brains.
The fourth lesson is that you can’t make it alone.

This time I am taking a different tack. I am studying with a partner. My focus will not be real world implementations, it will be on all possible hellish combinations a proctor could come up with. . I will be spending many late nights working on my speed.

I have passed All of Cisco’s storage exams, including the Written qualification for the CCIE Storage Networking exam. At first I thought the biggest challenge would be getting ahold of lab gear. It is not like this stuff is cheap. However I have been finding more gear out there then I had though I would. This is a good sign.

I will be posting my experiences throughout this entire process. I am not under the illusion that it will be easy. Luckily I have the lessons learned from my attempts before the war, and a new found enthusiam.

Cisco Storage Partners – California… a very small list

Lets just start this out by saying, darn.. this is going to be expensive.
Now that that is out of the way, lets get started. Cisco publishes the hardware that is in the Storage lab.

Here is the hardware summary -

• Cisco Routers
• Cisco Catalyst Switches
• Cisco Secure Access Control System
• MDS 9506*
• MDS 9216*
• Port Analyzer Adapter
• JBOD
• RAID storage
• HBA
• 3rd Party Fibre Channel Switch

My guess is that this equals a basic routed network with a CS-ACS server on the backend.
It looks like there is also at least 1 pc with an HBA connected into one MDS. The one big question I have is on the connected storage.
My guess is that Cisco’s JBOD reference = Fibre Channel connected storage, and the RAID array mentioned is connected to at least one server.
If my guess is right then there is the 9506 and 9216 – (note, no I in the name) and a third party switch.

So lets start the shopping list.

1. Cisco Routers
I have those coming out of the yinyang, no need to purchase anymore for this lab.

2. Cisco Catalyst Switches
Mine are a little old, but I don’t expect a storage exam to have anything challenging in the switching arena. No need to upgrade there.

3. Cisco Secure Access Control System
Thankfully Cisco provides VAR’s with NFR binders. ACS will be loaded on HMB-SERVER1 in a vmware image. No expenditure needed.

4. MDS 9506*
Holy smokes, this is a lot of money. I have seen them on ebay for $8,000. This includes both sup modules. I would need to buy a line card, which I see going for about 1k. so $9000

5. MDS 9216
Still bad, but not horrible. I just saw one on ebay for $5500. Depending on lab requirements it may be smart just to get to 9216′s. so $5500

6. Port Analyzer Adapter
Best I can find is $2000 refurbished. I have a feeling practicing using this, and seeing the ethereal dumps is going to be integral to success. worst case this is 2k, best case beg or borrow $2000

7. JBOD
Normally you are looking at 2-4k for one of these. My strategy is to find an old Netapp shelf, and low level format it. I found one on ebay that ends in 22 hours for $89. Sounds good to me.

8. RAID storage
I am going with my guess that this is just to facilitate data transfers between storage and host. My tactic is to use the existing storage inside one of my servers. $0

9. HBA
Interesting – Only one HBA .This can be up to $2000 to buy new. Luckily ebay is my friend. I found a qlogic 2340 card for $50. My kind of deal

10. 3rd party Fibre Channel Switch
Luckily Brocade resells to everyone and their mother. IBM, Dell, HP, Compaq, ETC. I have found some Silkworm 2800′s for as low as $50 on ebay.
I do have my eye on a 3800 that is going for $24 right now (I hope it stays low).

So how much is the damage?

$16,700

Holy smokes I could sell my truck just to buy the lab gear.

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……..

What should I do this thanksgiving break?

I found an intersting article on Light Reading
Let me summarize the interesting Items.

Team hightlights
1. Nuova is led by Cisco’s former Chief Development Officer, Mario Mazzola
2. J.R. Rivers, a Cisco Distinguished Engineer who led the team that developed the Catalyst 3750 switch is on board.
3. Tom Lyon, who founded Ipsilion is also on board.

Visibility
This company is almost entirely in stealth mode. No press releases or released products.

Funding
Asside from Cisco’s investments they have refused all offers of VC funding.

Gossip
from Light Reading –

“The startup is presumed to be working on a virtualization project in the storage networking space — at the intersection of storage, networking, and computing.

The idea is that they’re trying to “aggregate compute IO from the server and centralize it into a single or small number of network elements, connected back to the servers via a high-speed low-latency ‘closed’ network,” one source says. This frees up processor memory and CPU cycles so that larger clusters of servers are possible.”

My opinion

I think that Cisco plans to jump into the clustered storage market head first. Netapp has just finished the integration of Spinnaker software with the deployment of Ontap GX. Isilion is making a killing on distributed storage. And everyone in their mother is trying to copy Googles GFS filesystem.

I think that Cisco is going to leverage the recently deployed Storage Services Module with its storage virtualization features to create an abstraction layer between products such as Nuova’s and the classic FC or SCSI connected server.

Update on the Cisco / Nuova connection

This news is interesting as it shows that Cisco is continuing their push into the application layer.
Its Application Oriented Networking blade directly competes with IBM. The content services switch competes with Sun, F5, Juniper and Netscaler. If Cisco can bring a distributed backend to the market that integrates smoothly with the middleware solutions they are currently proposing it will be unstopable. Anybody care to jump on this bandwagon?
