Big question: what manufacturer, and what support chips? Most of our Dells
have PERC 6xx or 7xx, which is good hardware RAID. We have several boxes
with the Intel RAID on chip - aka fakeRAID. They are a *pain*, and we had
them just present unRAIDed drives, and used the very nice to use Linux
software RAID.
