RE: 5727 and 5776 (520+ disk options)

We do not have any drives in our 520 system unit.  We have both a 5094
and a 5095 towers that hold all of our drives.  Our load source is in
the 5095 tower which was attached to our original 820.  We move the 12
internal drive from the 820 to the 5095 tower and replace the old SPD
migration tower with the 5094 and new drives.  We had lots of drives
since we added the new tower and loaded up the drives prior to the cut
over.  Really neat to change system with no unload / reload.  We moved
all the data from the old stuff to the new stuff while still live on the
820.  Then we just moved the 820 drives to the 5094 tower, used HMC to
create a new partition using all of the stuff.  And all of our
configuration / data was intact.  Got to love IBM.

Another point is that I wouldn't be trying to drive all 8 from the
imbedded controller, but instead with the added PCI-X  5776 controller.
I think i'm reading that at least some of the drives have to be driven
by the embedded controller on the 520s, but wanted to find out
definitively.

We just decided today that we're not going to put an IXS on this machine
(decided against BlackBerry Enterprise Server), so i've got some more
card slots to play with now and the no-expansion CEC looks more doable
now.
