64kb is the most common that I've seen. > Any recommendations for RAID arrays, should I make 4 arrays (SWAP, /, /usr > and /temp), or what do you recommend? depends how many disks you have.

Again, depends on how many disks. Raid 10 would probably be best if the controller supports it and if you have enough disks. I have a redhat 7.3 system at home here and it runs on a Mylex Acceleraid 150, with 5 Ultra 2 9.1GB[1] drives connected to it. they are in raid 5 with 1 hot spare. It works fine for the / partition. Good luck, I had a IBM ServeRAID a while back and it was very picky, it would POST about 60% of the time in an older P2 system, but in a newer P3 it would never POST. Maybe the card was bad(friend got it offa ebay I think). nate [1] DAC960: ***** DAC960 RAID Driver Version 2.4.11 of 11 October 2001 ***** DAC960: Copyright 1998-2001 by Leonard N.
