3 disks is the minimum quantity for RAID5: it's certainly not ideal,
but it is by no means useless. RAID5 setups can span 3 or more drives
-- I don't know what the practical limit is for Vinum or typical PC
raid controller cards, but the last time I used it (which I admit was
some years ago) Veritas Volumne Manager under Solaris made the strong
suggestion that no more than 7 drives be put into one RAID5 group.
Cheers,
Matthew
