What’s the “Big Deal” about Cisco UCS ver 2.0 Fabric?

What's the "big deal" about Cisco UCS ver 2.0 fabric?  Two words: bandwidth and flexibility. Cisco recently expanded the UCS product line to include an additional Fabric Interconnect (model 6248), an additional Chassis IO Module (model 2208), as well as software release 2.0 with many new features. The new 2.0 components support existing chassis and server blades, and are back-compatible to inter-operate with existing first-generation UCS hardware (in original modes of use.) Although the new models need not obsolete the original hardware, many of the recent Cisco UCS deployments by Ahead have opted to take advantage of the benefits of the new components. The new 6248 Fabric Interconnect packs 48 Unified Ports into a 1 RU form factor. Any of the base Unified Ports may be configured to ...

Building Out Ahead’s Data Center Lab Series – Part 6 – Networking Double Vision

The only thing better than one Cisco Nexus 7010 is…. You guessed it – two Nexus 7010s. As I’d mentioned months ago in this space, the lab equipment is never going to be entirely static; we’re always try to build an environment that represents both what customers are doing in their environments today, but also represents what they might start thinking about for tomorrow. The initial round of diagrams I had put together indicated a sort of “OTV-in-a-box” (with an external L3 10GE switch to provide our L3 "cloud") approach to networking, where we were going to leverage the virtualization functionality of the Nexus 7000-series to partition 4 Virtual Device Contexts (VDCs) to parcel up the networking elements for both Data Center 1 and Data Center ...

Building Out Ahead’s Data Center Lab Series – Part 4

After spending the bulk of the blogs on the storage devices and their role in our new data center lab, I wanted to write a bit more on the networking configuration we plan on implementing. Networking, in the context of this article, is specific to traditional LAN networking; I've left the fibre channel element out, for the most part, except where necessary. As always, our lab is in a fluid state from a configuration perspective, so some of this is subject to change. It's how we need to be to ensure that we're able to provide a dynamic and scalable environment for our customers to come in and work on. With all of that said, there are a couple of designs I've been building out, in ...

An EPIC journey with an EPIC ending – Part 5: The Finale

“That just happened!”  ~Ricky Bobby As I was leaving Wausau Thursday night, I reminisced on the events that had transpired over the four-day period and a feeling of calm awe washed over me. In my head, I had one of those moments where I was truly shocked at how incredible things turned out. In spite of all the glitches and people that thought it could not be done, we had utilized next generation datacenter architectural principals and equipment and absolutely crushed what we thought was possible from a perspective of virtualizing Tier-1 mission-critical application workloads. All of the times I have stood in front of audiences and talked about how incredible VMware vSphere is and all the times I have pontificated about the advantages of the ...

An EPIC journey with an EPIC ending – Part 4: Execution and Results

“The best laid schemes of mice and men / Go often askew” ~Robert Burns As with every great journey, there are bumps in the road. Our execution of our test plans was no different in that regard. However, with an incredible team of guys from Aspirus and Ahead and with the backing of some amazing vendor partners, we persevered and gathered some truly extraordinary data and results. Since we laid-out the test plan in Part 3 of this blog series, I figured I would keep to that layout and give the results of the execution of each phase in the same format. Test #1: “Bare Metal” The execution of Test 1 did not end up taking place as we intended. An issue with 64-bit print drivers in EPIC ...

An EPIC journey with an EPIC ending – Part 3: The Test Plan

Once we understood the application architecture and the challenges we were up against, we needed to develop a test plan in order to validate the VMware/UCS architecture. Once again, we enlisted the help of the Aspirus team and sat down together to figure out how to approach the deployment. The first interesting challenge of the test plan was that there is no such thing as a Hyperspace load simulator. This meant that in order to truly test the capabilities of the next-gen infrastructure, we had to test with real users, in production. Typically, I would be the first person to say: “No way should we test in Production…” but there truly was no other way we could have been able to put a load on the ...

An EPIC journey with an EPIC ending – Part 2: The Application Architecture

As we set out to tackle the challenge ahead of us, we put together an all-star team of architects and specialists to analyze what it would take to successfully virtualize this environment. From the Aspirus team, we enlisted help from their lead architect and team lead, Tom Whalen and from Phil Hammen and Jesse Kozikowski to help us fully understand the architecture of the application and existing infrastructure components and develop a test plan that would allow us to isolate specific variables and test for success. Application Architecture Up to this point, we have been talking about “Virtualizing EPIC.” Many folks have been asking me, exactly what did you virtualize? What we virtualized was the Hyperspace layer of the EPIC application stack. This is a client-server application ...

An EPIC journey with an EPIC ending – Part 1: The History

A few months back I had a meeting with Glynn Hollis at Aspirus and he told me his biggest pain this year was in his EPIC environment and he would love if Ahead could help them overcome their challenges. They currently support 2500+ users in their healthcare system but that is just the beginning of what they will grow to in the next couple years. The biggest issue they have is that the environment has grown to 20 servers just to host the Hyperspace application for their environment and if they grow as they estimate they will it would grow to a ridiculous number of physical servers. Of course, the first question we asked (not yet knowing the depth of talent Aspirus has on their team) ...

Cisco enters the VDI space with a bang!

Cisco announced their new VXC line of virtual desktop endpoints yesterday. In this announcement, they discussed the simplicity and elegance of integrating a virtual desktop thin-client directly into their IP phone platform. The concept is revolutionary in my mind: Take something that every worker has to have on their desk and give it the ability to provide them with desktop services as well as voice and video services. The device I am mentioning is the VXC2100 which attaches directly to a 9971 IP phone to provide an endpoint that is capable of integrating with VMware View and Citrix VDI technology stacks. The device is the first step for Cisco in a portfolio of game-changing user access devices that are in development. As many know, Citrix has been ...

Planes, Trains and Vblocks

Getting From Here to There I’ve been spending a lot of time on my local commuter railway system recently. In my previous jobs, I never had the opportunity to do this, since I always found myself driving across multiple locations within a day, none of which were convenient for mass transit. With my new company, however, I find that my office and my customers are all in the downtown area, affording me the opportunity to take the train system each way on a near daily basis. I’ve also been spending a lot of time thinking about converged or stack infrastructures, and the various approaches in the industry to providing these offerings to customers. What are you paying for? When I board the train, and hand the conductor my ...
