I have access to many boxes that have two disks, support native Intel
MatrixRAID, and proper hot-swap backplanes. I also have access to a
Promise TX4310 card, which I can hook up to said servers (vs. using the
onboard ICH7).
I should be able to reproduce failure scenarios (pulling disks while in
a RAID-1 configuration, etc.) on those systems and report back here.
Would that be ideal?
