right.  FC is sort of SCSI with badly copied bits of eth/IP added ;)

from an FC-connected host plugged into the Brocade?  the presence 
of a hop over IB should be irrelevant, assuming that discovery/naming
kinds of things work.  if an FC-connected device can see the storage 
exported through IB->FC at all, it certainly should be bootable.
