Key Nexus Hardware Features

Michael Morris who maintains an eloquent blog at Network World on the Cisco Subnet wrote this blog entry about some of the hardware features of the Cisco Nexus 7000. Michael’s Article. (I say this even though he doesn’t like the name…yet :) It will grow on him I am sure…. Read More »

Colin on Usability

I saw this post hit today on Colin McNamara’s Blog here.Colin writes about key usability features on the Nexus 7000 from an operational perspective after his hands on time with it at last weeks SE Virtual Team meeting. I especially like Colin’s suggestions for us to continue improving the product line. Thank you.dg Read More »

Expecting and Getting More from Your Data Center

Green is definitely the new black. Much more than a just a trendy fad, though, it’s an important business concern that is driving not just good corporate citizenship, but also innovations in how we approach technology and processes. And the data center is at the heart of this opportunity.Blade Watch http://www.bladewatch.com/2008/01/23/how-can-we-evolve-the-way-we-use-the-data-center/ recently reported that according to IDC, energy and cooling expenses will grow eight times faster than purchasing costs of new servers through 2010. They go on to quote Christian Bertrand, ME Business Development & Support Director at APC-MGE as saying,”Building completely new data centers might be cheaper than reorganizing conventionally-built ones, even in the medium term.” Read More »

Containing IT

James Staten from Forrester writes a very good article today at http://blogs.forrester.com/it_infrastructure/2008/02/how-big-is-your.html that talks about the high potential value of a containerized approach to IT in large megacenters. Let’s start for example with a 2.5 to 5.0 MegaWatt containment unit with all cooling, power, compute, memory, and storage in there for the execution of a given amount of workload. There would be some central shared services: DNS, Central Storage, ILM, Backup, etc… Read More »

WHY YOU’LL WANT THIS SWITCH, PART 1

February 1, 2008 at 12:00 pm PST

As I Google”Cisco Nexus” and look through the articles, it is a rare article that doesn’t mention the”15 terabit” number within the first couple of sentences. I can certainly understand this because its a sexy number and its an easy way to quantify the engineering goodness baked into this platform. But, to be honest, if, after spending all this time, money and effort on a new platform, all we could talk about was speeds and feeds, it would be a little sad.Ironically, the reason I think folks will want a Nexus are a couple of areas that have not gotten much press so far. The first of these”secret weapons” is NX-OS, which has actually been a source of some trepidation. So, first off,”new” is a bit of a misnomer. What we did was start with the proverbial clean sheet and design an OS explicitly for the data center. We had the latitude and R&D capability to cherry-pick from the Cisco technology pantry and build from scratch as appropriate. So, we chose SAN-OS, which has been running for over 4 years in some of the most demanding enterprise data centers out there, as the foundation. Likewise, our layer 3 code, from our Procket acquisition, has been deployed with several major service providers for a number of years. Finally, our layer 2 code was written with the same team that made the Catalyst so successful. Read More »
