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.
