Re: Switch fabric and Backplane in 6500 with Sup 720
Think of the backplane as a highway and think of the modules are the cars using that highway. If you have a car that can only run up to 40 miles per hour, that's how fast the highway is.
In the 6500 chassis, the backplane speed depends on the module you have inserted in the chassis. If you insert all DFC dual-fabric modules along with a Sup720, then you will achieve the maximum speed of 360Gbps Full Duplex - which in marketing terms equals to 720Gps.
That's 7 modules running at 40Gbps = 280Gbps, with 2 Supervisors also running at 40Gbps = 80Gbps.
If you take a moment, the URL pointed out on this thread contains all the information you may need regarding the 6500 architecture. It's a long read so many people tend to skim thru it without really digging deep into it. It has all the answers for the question you just posted.
