So, before we dig into CEE (Convergence Enhanced Ethernet), I have a quick quiz for you: take a look at the two pictures below and make note of the differences:
Ready? OK, back to the topic at hand….So, one of our competitors marked their entry into the realm of Ethernet switching with an FCoE capable switch. I honestly thought was kinda cool, since their actions continue to validate a vision, Data Center 3.0, we laid out almost two years ago and a unified fabric strategy we laid out a year ago. During their launch, however, the company made a curious pronouncement: said newly announced switch was the “industry’s only end-to-end Fibre Channel over Ethernet (FCoE)-based solution that brings the Fibre Channel (FC) standard and Converged Enhanced Ethernet (CEE) together.”This had me scratching my head a bit since we announced the Nexus 5000 a year ago, with a fine collection of ecosystem partners, and have customers with the solution in production already. Perhaps there is something magical in CEE that I missed? Well, if you read IBM’s Redbook paper on FCoE and CEE, you will see that CEE looks remarkably similar to our discussion of the elements of Data Center Ethernet (DCE). The reality is that neither CEE and DCE are standards but rather marketing shorthand for a half a dozen extensions to the Ethernet standards that are in the process of being finalized and published--the exact same standards. We collectively came up with constructs like DCE and CEE because “IEEE 802.1Qaz” and its brethren is somewhat awkward to into conversation. Thankfully, this naming dichotomy is going to be short-lived. As the standards move towards finalization, you will either see adoption of the formal name, such as Data Center Bridging (DCB), of they will simply be folded into the term “Ethernet”, as has happened in the past.Oh, and as for the ducks, much like DCE and CEE, they are the same.
Taken from the GigaOm Green:Net 09 show in San Francisco on March 24th, 2009. Moderated by Rich Miller of Data Center Knowledge, this is a good sampling of how large IT vendors are looking at Green from both an industry as well as a data center standpoint.This is a good view if you want to understand some of the higher level considerations of getting more Green in your data center. Most of the panelists also provide some insight into new technologies that are coming to market to help in the deployment and management of energy. Our take was on Cisco EnergyWise as a means to implement common monitoring and control of data center energy.Panelists for this session were:Kenneth Brill, Executive Director, The Uptime InstituteAlbert Esser, VP Power and Infrastructure Solutions, DellRich Lechner, VP Energy and Environment, IBMChristina Page, Director Climate and Energy Strategy, Yahoo!Myself, Robert Aldrich, Principal, Energy Management Solutions and Services, CiscoWhat was clear to me… Read More »
We just posted an a new document to the website that provides further detail on virtual networking with the N1KV. A key part of the doc is a comparison of the existing VMW vSwitch vs the new VMW vDS and the N1KV. It gives you a better feel for how we can expand the role of server virtualization in the data center with more sophisticated networking capabilities.
David M. Smith of Gartner spent some time with me a few weeks ago exploring Cisco’s cloud computing vision. I walked him through a variety of concepts, such as private clouds, virtual private clouds and open clouds. We also spoke of the vision of an “Inter-Cloud”, a vision shared by most cloud enthusiasts here at Cisco, including our CTO, Padmasree Warrior. David had some excellent feedback, and I enjoyed the conversation very much.
Unfortunately, I think David came away from the conversation with a slight mis-interpretation of how we use the term Inter-Cloud. As he states in a post on his blog, “Life on the Inter-cloud”: Read More »
