    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.
