But this was a few years ago when most people buying servers wanted them for Windows Server use, not Linux or *BSD. Now RAID doesn't even come into the pre-sales talk anymore - whether it's because they're more aware of O/S's that do software RAID, or because most Dell HBAs now support JBOD/pass-thru or just because they know we've no intention of running Windows on their servers, I don't know.
