This is what I thought, though I am unclear on the raid 0, + raid 1. For
instance how many hard drives total would you recommend? If I have two
controllers how would I partition the applications such as the OS, IMAIL
(spool), Imail (users)? I figure that I would use 6 total two drives
running raid 0,1 on one controller for the spool, two drives running raid
0,1 on the second controller for the users, and finally I would use a raid 0
for the OS?? Am I seeing this correctly or not?
Thanks for all your help.
