Uh, how do you figure? 3 18G UW SCSI drives @ $300 = 36G RAID5 storage for $900: $25/G 2 18G UW SCSI drives @ $300 = 18G RAID1 storage for $600: $33.3/G RAID5 is cheaper (per G) given your 3 vs 2 disk scenario. RAID1 is 2/3 the total price of RAID5. > for dpt-2100S... dpt is typically supported... > but which distro and which kernel might affect "it's supported"... > - try it and see what happens Older DPT cards work fine ...
