Supervisor32 still relies on the 32Gbps shared bus and line card modules on this box will be non-fabric (classic line cards).


You will be oversubscribed at the ingress port before it hits the inter-switch links.

Oversubscription rates are very dependent on how busy you expect the hosts to be. For user hosts you might try the old ratio of 24:1, which for 10 gig to gig would support 240 gig ports.
