Eh - same problem with SCSI, except SCSI cables have the neat little
screws to make that harder.  It's a good point, though - a SAN is a
network.  For proper redundancy, you need two separate fabrics (read:
redundant paths from storage to host that pass through two different
switches, with the switches NOT being cross-connected) and some sort of
software such as Veritas DMP to handle multi-path and failover.

Thanks,
Matt
