I have a deployment coming up with a 6513 with FWSM and dual Sup720s.
A customer just asked if the 6513 supports as many dual fabric slots as the 6509. He said the 6509 supports all 9 slots for dual fabric but the 6513 only supports 6 slots.
First, is this true? And second, why does it matter?
Thanks in advance for any help you can provide.

dual fabric provides 40G backplane connection vs 20G backplane connection.
It's also a physical limitation, if you buy a dual fabric module, you can't insert it on a single fabric slot.

Yes, 6509 has dual fabric slots 1-9
On the 6513 only slots 9 - 13 are dual fabric and the sups 720 have to go in slots 7 and 8

Slot 9 thru 13 are dual fabric in addition to 7 and 8 for the Supervisor - so you are looking at 5 regular slots with 2 Sup slots

So basically what the dual fabric buys me is two paths to the switch backplane.
I could technically design it so that just workstations are plugged into non-dual fabric blades and in case of a backplane failure (does that even happen) then they would fail over to the backup 6513. I would just have to have enough slots that didnt need the dual fabric redundancy.
Current setup is:
Slot1: FWSM
Slot2: ACE10
Slot3: x6548 (workstations)
Slot4: X6548 (workstations)
Slot5: x6724-sfp
Slot6: x6724-sfp
Slot7: Sup720
Slot8: Sup720
Slot9: 6748-GE (servers)
Slot10: 6748-GE (servers)
