A Pretty Decent Ethernet Switch

With all the talk of the Nexus 5000 being the first FCoE switch on the market, we tend to forget that it is a pretty decent Ethernet switch as well. Mario Apicella is about to put the Nexus 5000 through its paces with a variety of tests that will show it to be a very high performance switch with over a terabit of switching capacity. More importantly, it does the little things well, too. For example, the ability to learn MAC addresses in hardware. This comes in handy in virtualized server environments where a switch has to quickly learn thousands of MAC addresses. Trust me, I remember the data center meltdowns caused by switches that performed MAC address learning in software.For a quick overview of all the features that make the Nexus 5000 a world-class Ethernet switch, please take a look at the data sheet. You’ll notice its ability to forward over 700 Mpps at latencies of around 3 microseconds. Again, a pretty decent Ethernet switch.

NXTcomm update- Cisco Nexus 7000 finalist for EOS award

Here at the NXTcomm08 tradeshow (June 16-19, Las Vegas) the Nexus 7000 has been awarded finalist status in the prestigious EOS Awards for Excellence in Technology innovation. Cisco would like to thank the NxtComm08 EOS selection committee, which has clearly recognized the innovation that the Nexus 7000 brings to the Data Center via support of transport flexibility, operational continuity, infrastructure scale and unified fabric, creating a new category -Data Center Class Switch- in the process.

A Nexus 5000 With Your Name On It

June 7, 2008 at 12:00 pm PST

We passed another milestone on the execution of our Data Center 3.0 vision this week with the first customer shipments (FCS) of the Cisco Nexus 5020. Since it will apparently too expensive to drive or fly anywhere this summer, may I humbly suggest you order a couple of them to play with over the summer. Speaking of playing, if you have never played around with Kaon’s interactive 3-D models, they are very cool. Check out the model for the Nexus 5020 and the Nexus 7000.

Cisco’s Green Crystal Ball

June 6, 2008 at 12:00 pm PST

On a day when oil hit $139/barrel and I just paid $4.72/gal to fill my gas tank, this interview with Paul Marcoux by Chris Morrison offered some interesting perspectives on energy efficiency in the data center and where Cisco is going. As some of you may know, Paul, a founding member of The Green Grid, recently joined the Cisco Development Organization as the VP of Green Engineering, so he would know better than most. One of the things Paul points out is that you need good data to make good decisions. It is one of the things I have talked about in previous posts and you will continue to see efforts from Cisco on providing good data; however, as Paul points out, there is much oppty in this area on all fronts. Check out the interview--Paul has some interesting perspectives.

Catalyst 4900M: Good thing in a small package

June 4, 2008 at 12:00 pm PST

I was making a valiant attempt to work through my ever-deepening backlog of email yesterday and I ran across something that reminded me that even though the Nexus 7000 got the lion’s share of the attention in our January DC 3.0 Switching launch, there were also a couple of other hidden gems that should not be overlooked. One of these is the Cisco Catalyst 4900M rack switch. I finally go to an article by Cameron Sturdevant in eWeek that took the switch through its paces and came to the the conclusion that “Cisco’s new switch deserves a spot near the top of your data center equipment evaluation list.”
