In every customer discussion I have had about Nexus 5000 the Server & Storage teams attended the meetings and all were very interested and engaged, there was no animosity or hostility, just tons of great questions. FCoE is good for the Server & Storage teams. FCoE gets more servers connected to Storage. When every server that is Ethernet connected is also by default SAN connected, that makes the Storage guy much more important and valuable. FCoE is a win/win scenario.

Storage people in one corner, and Networking in the other corner. Storage people now claiming Ethernet is a networking technology (oh stop it, stop tickling me) after their much vaunted Fibre Channel "networking" technology seems to have lost its mojo. Is this the start of Storage networking actually moving to IP, oh No, the sky is falling Chicken Little. Now we get to see a repeat of the Telephony / VoIP fight.

Six 42U racks on each side of the networking rack all loaded with 1U servers would be a piece of cake. Given that we also sell a 640-port 21U 10G Edge switch we could configure Twinax between computers and the Edge switches and fiber between Edges and multiple centralized 512-port Core switches the limit of 10M on Twinax is manageable. Actually up to 8,192 computers it's pretty easy, after that it takes a little thought!
