hi all...

i'm working on building a DR server (which is likely to be a 989...but
whatever it is, it will not be a pci system (just too $$$)).

i'll need to attach ~350gb of disc to this box...hence my subject
question.

i know i can do (multiple) mod 20s, but i am worried about the age of
these arrays (not to mention the discs and the batteries) as well as
the total amount of disc that needs to be attached.

there are also the 12h's.  am i correct in thinking that they can be
'locked' to a particular mode...and that way get around the autoraid
performance problem?  and again, what about the total disc...?

finally, there's a va array (7100 most likely).  i already have four
fibre-to-scsi routers, so that's not a problem.

for either of the scsi arrays, i'm probably(?) looking at multiple
chassis?

i should say that i'm not concerned about performance in the same way
that i would be if this were truely going to be a production server.
so, for example, i know that if i were to go with a va...the routers
are going create a bottleneck...and that's ok.

what about io slots on the back of this box? am i looking at needing an
expansion bay?  (i think so...)  there will be at least one additional
controller card for a dlt.      - d 'lots of questions'
