Follow this link to see a demo of the Nexus 1000V and how it interacts with VirtualCenter to set up VN-Link services.

Does Going Green Reduce Energy Use?

Well- sort of.Had an interesting”Green” data center discussion at a conference this week that addressed some nuance on the developing taxonomy of energy efficiency in IT.So- to pose a specific question:Will adopting energy efficient solutions from best of breed partners and vendors reduce the total amount of energy your business will use as it grows? The short answer is no, at least not if your business is growing.Here is the thing, energy usage basically mirrors productivity. Unsurprisingly, countries with the highest GDP also use the most energy. This directly translates into our business operations. Whether you’re a company that scales through adding more headcount or by adding more compute and multimedia per headcount, you are using more total energy.imageIn data centers, users translate into hardware. The more productive and complex the business becomes, the more complex and energy intensive a data center becomes (typically). So assessing the efficiency of a business’ operations can also translate into energy efficiency. I stress the word”can” here as we often don’t have resources invested in managing the translation between the two. We have a very large retail customer who has translated it very well. Read More »

Why virtual-routing may (possibly) become reality

One of the great things about the concept of cloud computing is the possiblities it creates for large, disruptive markets. We talk about compute capacity markets and the like all the time--that’s the commoditization of IT infrastructure. But, as Simon Wardley would be quick to point out, the commoditization of one technology almost always leads to the opportunity to innovate others. What are the new technologies that cloud infrastructure will enable?

An interesting discussion broke out in the “cloud-o-sphere” this week surrounding a related comment from our own Doug Gourlay at Cisco’s CScape analyst conference last week. In talking about the effects of cross-cloud workload mobility to Andreas Antonopoulos of Nemertes Research Group, Doug mentioned the concept of “Virtual-Routing” (a horrible term), the idea that one can move the compute loads to the best network location rather than rerouting the network to the workload.

Old Dog, Web 2.0 Tricks

December 18, 2008 at 12:00 pm PST

imageOK, so, lets be clear: I started in this industry when the DEC MicroVAX was considered controversial and the vampire tap was the pinnacle of networking technology. So, needless to say, “Web 2.0″ and “Social Media” left me a bit skeptical and certainly scratching my head (thank you @deanna24 and @ethanbauley for your patience!).But, I have to tell you, having been an active participant for the last year and watching things evolve, I am a believer--I think we have seen a permanent shift in how folks interact with each other and how companies interact with customers. Speaking from experience, that shift can certainly be brain stretch, but I think it is a change for the better for both companies and customers.Colin McNamara’s recent post on using our online config tool is a great example of pulling all the pieces together via blogging, embedded video, and Twitter to educate readers--at the same time, we get to immediately understand what works and what does not work for customers and sharply reduce the cycle time to address issues. Same thing last week, when I could follow the real time conversations around our C-Scape analyst event by following #cscape. Read More »

EMC technologist discusses FIbreChannel over Ethernet (FCoE)

Stuart Miniman from EMC leads a whiteboard ‘chalk-talk’ on FibreChannel over Ethernet. An important part of Cisco’s Data Center 3.0 initiative FCoE is continuing to be embraced by an ever larger vendor and now customer community. With over 250 customers having adopted the Nexus family of Data Center class switches we are well on our way to a unified fabric- one where everything goes over one network; but also where every host is capable of accessing all storage resources, without disrupting today’s effective ITIL processes and defined workflows.
