C7000 Expansion

[grinningdevil]

Hello,

Question related to adding a new chassis to existing setup ! 

Existing Infra :> 2* c7000 Chassis

 First Chassis:

5* BL680C G5, 1* BL460C G8, 2* BL460c G6

 4* HP 4GB FC Passthrough module (Module 5,6,7,8)

4* Cisco Switch 3020 ( Module 1, 2 )

Output = 4*1GB

Second Chassis

5* BL680C G5, 1* BL460C G8, 2* BL460c G6

 4* HP 4GB FC Passthrough module (Module 5,6,7,8)

4* Cisco Switch 3020 ( Module 1, 2 )

Output = 4*1GB

Now we need to expand this by adding another chassis – C7000, with Flex10/10D modules or Flex Fabrics.  As I understand, Flex10 support SFP, whereas the older 3020 do not support it.  So what is the solution to add this new chassis to older Infra ? Which cable to order, which connection etc ? (we are thinking about Active Active 10GB uplinks )  Attaching the relevant quote I got with 1GB transceivers.
