VHDCI would be a bit weird on that cable at the HBA side (going from

Ya, you'll have to do pics, or just come on over one evening and we'll
make it work.  If you want to wait until after your trip and you're in
no big rush, could do it at the next-next board meeting.

Adam's note of drive termination may be correct and that will solve
that problem if you can crack open the case.  My idea of making the
thing internal by taking it out of its case is probably the way to go.
If you're cracking it open to flip a termination DIP then you might as
well just get it all running via internal.  Hell, you can probably just
have it hanging half out the system ("an internal external!").

You may have trouble putting together the required external cables from
MUUG members without ordering something (and waiting...) if you try to
make it work all-external.

Checking checking... nope, not I; so another vote for an internal

Ha!  I was trying not to make Alberto's head explode.  On the bright
side, I've never actually seen a situation where the terminator
provided (or sitting in one of my boxes) proved inadequate.

Ya, avoid the PCI-X if you don't have the slot.  64-bit PCI will work
on any board, however!

Ya, good point.

Don't worry, much of your stuff is still here, and I'll let Alberto
know if he needs to thank you for the loaner part :-)
