Realy ? That's a bit worrisome for me. I have two servers I'm working on, (1 SQL 2K and 1 Ex203) each with a 2disk RAID 0+1 and a 3 disk RAID 5. (Those are both striping sets, aren't they?).
I had hoped to use some of the extra disk space on these two machines to make a separate partition for some computer admin storage. (install files and drivers on one, SUS-type things on another). I take it that you wouldn't recommend separate partitions on the RAID 5 then? (Separate partitions would be convenient for keeping our "other stuff" from accidentally clobbering the critical applications, but I'm sure I can find another way.)

With RAID1 (when the vendor does it right) there's not a significant performance impact from making two partitions. Three or more there would be no matter who made the controller. Also, any striped RAID there's always a big performance hit for partitions. -------------------------------------------------------------- Roger D.
