All, probably a little OT here, but I _am_ using SUSE Linux :-) I'm trying to work out the optimal (or near-optimal at least) RAID configuration of a 24-disk array. The array comes with two redundant RAID controllers each with six SCSI channels. These controllers allow all kinds of RAID0/1/5 configurations, but no RAID6. I want the array to be able to survive a two disk failure, so RAID6 would be the obvious choice, but ... So I'm sort of looking at choosing between - - using plain software RAID6 and ignoring the hardware RAID facilities of the array. - using the hardware controllers to build a combination of RAID0/1/5 that'll give me the two drive failure survivability. I've had a look around the web, but googling for "two drive failure RAID" almost always leads to someone talking about RAID6 ... So, opinions/suggestions? /Per Jessen, Zürich
