Cat6500 performance with 150 GE servers!!

All servers are planned to the same subnet -- L2 network. SupEng2 with PFC2 are must in the Cat6500 to provide 30Mpps/32Gbps L2 performance. Will it be useful to equip SFM2 and DFC on each line cards to increase the performance to 210Mpps/256Gbps.

Is DFC just increase the L3 performance in the architecture (also distributed forwarding on L2)?

Any comments are welcome!!

DFC is for distributed L3 functions.

Hope this helps,

That means Sup2, PFC2 and DFC enabled line cards cannot increase the L2 performance to 210Mpps. Just remain to 30Mpps for L2/L3 switching. Am I correct?

Hi

The SFM2 is reqierd to boost L2 AND L3 from 32Gbps to 256 Gbps.

The DFC permits to handle the L3 and L2 local on one linemodule without use the bus to SE or SFM. This only for traffic that has the source and destination port on the same linemodule. n DFC bulid a kind of n sub swirches in one big switch.

I hope this helps .
