[Gllug] Hardware SCSI RAID

[Matthew Cooke]

gah. had software raid on fedora and wasn't impressed at all. a disk failed 
and wrote something into a log and I didn't notice for 2 months. Also, 
replacing a failed disk seemed non-trivial.

I was under the impression that the adaptec scsi/raid were pretty popular 
but you have made me nervous now!

    Beware of hardware RAID controllers as they may use any, possibly
non-standard, format for the discs, and may also rely on software run by the
main processor rather than an on-board processor, so may not be true
hardware RAID. If the controller dies, there is no guarantee that a
replacement will recognise the data. The only advice I have seen is that it
is often better to stay with software RAID.
