Re: Nexus in DC?

The Nexus 7k. Of the 32-port 10GE linecard, you can only use 8 specifically
marked ports if you want the full non-blocking 10GE due to the backplane
connection. End 2009 they will release a linecard with 230Gbps backplane
connection, so that should give a little better port-density vs.
performance. Also the Cat6500 is oversubscribed as it also has a 40Gbps
backplane connection and you can buy 8-port 10GE linecards and 48-port 1GE
ones.
So I really like the non-blocking idea of the Juniper EX8200, great selling
point :-)
