Which reminds me of a comment I saw somewhere about
the possibility of having
a SCSI bus with more than one host adapter on it. Is that even possible?
Absolutely, as long as the two (or more) host adapters have different
addresses. There are some computer systems that share disk units in
that manner. Of course, the driver software on all hosts needs to be
aware of the need. AFAIK, one can even talk controller-to-
controller.
The problem with multiple controllers arises when low-end or spottily
implemented driver software is used. For example, it's the rare
cheap SCSI card that will respond to an IDENTIFY--or even allow one
to change the host address.
Let's see ya do that with IDE/ATA!
