I've taken on board all that has been said here (and emailed to me)
and I've decided to go for the hardware solution, largely because of
the lack (at the moment) of RAID5 support in Linux. I saw the software
overhead of striping (RAID0) as a minimal one, with the benefit of
reduced average seek time under load (I have a friend who, it turns
out, has his swap space striped across discs). The machine I'm
building is to be a database server, and so I saw the disc system as
the bottleneck, not the processor (especially with all THAT processing
power). Part of the original spec was '...and do it as cheaply as
possible', but that condition has been relaxed in favour of
reliability (the RAID5 requirement), so we're just trying to pick a
card now (looking like the Adaptec 3985UW, but you folks seem to like
the DPT and Buslogic cards, so I'll be getting more info on those
Many thanks, all!
