Hi John,
I once set up a couple of Macs with simultaneous connections to Unity
and a SanMP fibre volume. I used ATTO Celerity FC-42ES cards and just
used one port for each SAN, which worked fine.
As far as the slots go, I think the Expansion Slot Utility only existed
in the first model of Mac Pro (the 2007 model). In later models the
slots have fixed widths. In theory, all that should matter is ensuring
that each card is given enough bandwidth to do its thing. Since the
Celerity cards are only 4x cards they should be happy in any slot
(except under certain configurations in the 2007 model where you could
have a slot at x1 or x2) - I'd imagine that the Ellipse card would be
the same, although I don't have any experience of those. It is possible
for drivers to conflict which might be the reason why you are having
trouble using the two cards together - if you have to disconnect the
SanMP volume to get the Mac to boot then it sounds like something is a
bit unhappy as this is not normal.
I don't think I've ever put two fibre cards in the same Mac, but you
should definitely be able to see all the installed cards in the the "PCI
Cards" section of System Profiler.
