Modular with 2 Tbps Backplane Bandwidth

Hi

I'm looking for a modular switch with below requirement

Slots: 9

SUP-2

Backplane Bandwidth- 2 Tbps

Please suggest!!!

I was looking into 6807 it has backplane B/W of 11.2 Tbps with 7 slots. Also checked out 6509E.

It would be a great help, if anyone can help me on it.

Thank you

Unfortunately, Cisco doesn't always clearly document the bandwidth of the chassis backplane itself.  As an example, the 6500-E chassis supports more bandwidth and power then the non-E chassis, but neither was well noted until Cisco released the sup2T or the larger (e.g. 8700W) power supplies.

Right now, the sup2T provides a 2 Tbps fabric, but the chassis and/or line cards may restrict how much of the fabric bandwidth you can utilize.  For example, a 6500-E with 6900 series line cards have 80 Gbps per slot, so to take full advantage of the sup2T's 2 Tbps, you need a 6513-E, 13 slots @ 80 Gbps * 2 (duplex) = 2.08 Tbps.

That noted, on the bandwidth issue, NDA might still restrict me in what I can say, but the 6807, if the fewer slots is acceptable, is probably (cough) a better long term investment.
