[c-nsp] Small DC switch design

Hello, I'm working on options for a small DC switch design. This DC has 5 virtual hosts with 10-20 guest vm's each. Each server has two quad port gig nics with 6 of the 8 gig ports connected (3 for iSCSI and 3 for data or management. It also has two 3 node sans each with 2 gig ports per node,
