to be a RAID setup? I don't remember...
Those should be 36GB each.
This should be a RAID 5 array, 2+1, for a total logical volume of
whatever, 72Gb-ish I guess?
Upon closer inspection, though, it looks like I've made a slight
mistake.
LSI 20320 1 Channel U320 SCSI Controller is what I ordered.

This card only supports RAID 0 or RAID 1.
For our immediate purposes, which do we want? Mirroring (safety) or
striping (performance)?
I'm thinking, but correct me if I'm wrong, that we can have one of the
other machines run a replicator, giving us safety, and then we can do
striping on this machine for performance.
In the future, when geoffrin is healthy and is the primary, Jimbo the
President of the Wikimedia Foundation, Inc. will call Jimbo the
President of Bomis, Inc., and complain. Jimbo@Bomis is responsible
for the error, so we'll make him pay for a new card!

p.s. In any event, is it reasonble to suppose that I need to do
something hardware wise to setup striping?
