In that case, my feeling would be that if the server was purchased with a
RAID controller1], that's what should be used [2].
1. With the exception of the PERC 310, which I really dislike, the first
version ofthe PERC 7, which *only* allowed DELL h/ds, and Intel
FakeRAID.
2. Otherwise, that's a nice chunk o' change that was wasted in someone's
budget.
