A UCS blade can run any Intel workload on all the mainstream OS’s- Shocking?

February 2, 2010 - 0 Comments

Steve Chambers embarked these days on a series of posts designed to open our eyes to a new approach to IT infrastructure. Sounds ambitious or arrogant? Well, Steve is a well known and respected blogger, who capitalizes on his deep knowledge of Unified Computing systems as a Cisco  Data Center Architect. As Steve Kaplan  another well respected IT blogger wrote on this blog “Excellent post Steve. I write and talk extensively about UCS, but didn’t really think about the benefits described in your Last Thought.”,  

We have been talking extensively about the extended memory technology provided by the UCS. While Steve does not discuss in this blog, it’s definitely a key feature of the UCS that further increases the OS flexibility and ROI he describes.

In his post , Steve is bringing on another key differentiator of the UCS “This post explains how Cisco UCS offers IT infrastructure a new way of working with stateless computing.  You could manage UCS the way you manage any other compute platform with the minimum of change, just like you can drive a Ferrari the same way you’d drive a pick up truck. But should you?  No, you shouldn’t, you’d be wasting a fantastic opportunity”

“So how  does UCS change how you drive your infrastructure?” To answer this question Steve starts with a brief description of four types of workloads (Oracle RAC database, IBM Websphere, Microsoft Windows 2008, VMware vSphere 4) and how these workloads can all run on the same blade type without any human having to reconfigure the compute, network or storage. He then reviews six UCS features (WOW-A, Unified Fabric, Over-commitment, Service Profile, Virtualized CNA and Stateless Computing) which contribute to what Steve describes is “about increasing ROI and reducing complexity, and therefore reducing OpEx”.

This first pass is just the beginning , as Steve will provide in six follow-on posts practical examples of each of these six UCS features


As Steve wrote also  (competitive products do) “not have the vSphere integrations at the ethernet protocol level that Cisco UCS has. That is very, very unique. In fact, …comment just shows how little folks appreciate how different UCS is”   I am sure that Steve’s series of blogs  will definitely  help to see the UCS in a different perspective and contribute to the appreciation that this platform deserves.

So please read Steve blogs and share with us (and him) your thoughts –
