Hi Greg

I'm no expert but I configured two servers using HP's hardware raid
configuration a couple of years back and didn't do anything in Debian to
configure Raid.  More recently, I set up two more servers using software
raid1 (mdadm).

I believe you either do one or the other, not both.

FWIW the later two servers have SATA drives and I'm using 2.6.8-1-686
