You can have multiple hosts on one SCSI bus, thats how a lot of clusters
are built. Just need to make sure terminators are at the ends, and adapters
have distinct SCSI IDs. No need for FC.

Thanks for the reply. As usual I left important details out of my
post. I have to use Fibre channel, as the testing I'm doing requires
(from a driver perspective) that the interface be either Qlogic or
Emulex Fibre card. I've seen things like the RaidKing which will
present a Fibre interface to a group of IDE drives, which looks like
it would work, but I'm not sure how you slice off LUNs with such a
device, but what I'm really looking for is a quick & dirty way of
acheving the same thing, the Fibre equivalent of the aforementioned
copper t-cards on Ebay.
