Hi we are replacing HP pass thru module with Broacade SAN switch.

What is the concept of ISL , What does the below line mean.

Create ISL at storage switch  to Enclsore Brocade SAN switch.

Inter Switch Link

With your pass-through module, you needed to attach an FC cable to each pass-through port in order to connect the associated blade.

With a switch, you will need to attach a couple/few (one would work, but for performance and reliability you should use more...) FC cables from the new Brocade switch to the upstream SAN switch.  The hosts on the blade will have internal connections on the switch, and will share the bandwidth provided through the ISLs.
