I asked this same question and got an answer off list: Somebody said their SAN hardware used multiple initiators. I would try to check the archives for you, but this thread is becoming more of a rope. Multiple initiators means multiple sources on the bus issuing I/O instructions to the drives. In theory you can have two computers on the same SCSI bus issuing I/O requests to the same drive, or to anything else on the bus, but I've never seen this implemented. Others have noted this feature as being a big deal, so somebody is benefiting from it.
