    ICL - Chassi - Only available in DCX switches.

    ISL - Switch - In all FC ports.

     

    ICL - Special connector and cable and max 16 x 8 Gbps per cable

    ISL - SFP+ and max 16Gbps

    The technical differences have already been covered so I’ll just add a few comments from a SAN design perspective.

     

    The key advantages of ICLs are that they don’t use any front side ports and typical ICL configurations have considerably more B/W than would be reasonably possible with ISL designs. ICLs still connect to the switch ASICs as an ISL would and the switches on either side of the ICLs still have a different domain but from a high level SAN design perspective I like to think of them as extensions of the backplane. Just as ISLs, you can put them in a base switch and share the B/W with some or all logical switches in the chassis.

    robert,

     

    the max. amount - depend of DCX model 4 or 8 - of ICL is 16 in 8510-8

     

    in such case with both activated ICL POD License up to eight other Chassis can become Member of the Fabric.

     

    First DCX Generation support up to 4 ICL.
