Why Ethernet Wins…

OK, so the title is meant to be a bit ambiguous, as much a question as it is a statement–I’d love to hear your thoughts on this. I have been pondering this a bit since I am prepping for my CCIE re-cert and its kinda fun looking back at how much things have changed in 15 years. It also seems everyone and their brother wants to sell Ethernet switches these days. Companies that have never sold Ethernet are now all over it and companies that have repeatedly walked away from the Ethernet market keep coming back. So, what is it about Ethernet that makes it the networking juggernaut? Read More »

Join Us at EMCworld

Just a quick heads-up–we have quite a few interesting things going on at EMCworld this week, including a session by our Cisco-on-Cisco TechMinute celebrity Sidney Morgan. Listen to Sidney give a brief update on our sessions. Sidney’s session is “Case Study: Implementing Next-Gen Data Center Solutions” on Tues, May 19, 2:45-3:45 pm.We will also have a couple of our bloggers on-site, so definitely swing by the Cisco booth and say hello. While we will not be streaming live from EMC, we will be posting videos taken onsite and blog and twitter posts to our EMC World website at The videos will be of onsite interviews with Cisco DC execs and SMEs, demo owners, partners, etc.

Cisco Unified Computing System in Production

Our ConC TechMinute celebrity, Sidney Morgan discusses the deployment of Cisco UCS in our production environment and how it has improved power efficiency in our Richardson data center. You can also listen to Sidney discuss how we are integrating the UCS into our existing storage environment.

Chuck Hollis, EMC VP of Global Marketing and CTO, on FCoE, Virtualization and Cloud Computing

Cisco will be present at EMC World 2009 and on the web at “Live at EMC World” Bill Marozas ,Cisco Director Storage Networking, took this opportunity to ask Chuck Hollis, Vice -President Global Marketing, and well known EMC blogger tough questions “Chuck Hollis here from EMC. I was asked to “guest blog” for Cisco on a few topics that I found interesting. image I hope you find the questions (and answers!) thought provoking! Q: What is your view of the evolution of the Storage Networking industry? In particular, how do you see the use of transfer protocols evolving in the data center? I think we’re all pretty agreed on the end state of storage networking: Ethernet wins – period. It won’t happen overnight, but the outcome is inevitable, if you think about it. The more interesting questions revolve around the “how” and the “when” of this transition, rather than the final outcome. Right now, enterprise data centers are intrigued about the potential of converged Ethernet data center fabrics for their next generation architectures, and in many cases are building it into their long term plans. As a result, I think you’ll see a healthy co-existence of FC and FCoE for many years – traditional storage networking infrastructure working alongside newer converged Ethernet infrastructure using the same switches, management tools, etc. Very few customers would ever consider a rip-and-replace approach. A related debate is “what storage protocols will we see on this converged wire?”. For us at EMC, this really isn’t a religious debate, and more a case of customer preference driven by specific use cases.

Switch Architectures and Highways

Since Cisco first introduced the concept of oversubscribed Fibre Channel modules in the storage networking industry with the MDS 9000 Family, there has been quite a bit of confusion between oversubscribed and blocking architectures, often incorrectly using the two terms interchangeably. I’m going to use a simple analogy with the highway (where I spend too much time on, because of my commuting) to try to explain the not-so-obvious difference. Read More »
