Home -> Community -> Mailing Lists -> Oracle-L -> RAID 1 or 10 for Oracle redo/control files?
Hey all,
I know this as been brought up before, but I've been having some difficulty finding specific reasons for/against RAID 10 on Oracle redo and control files. Here's the info:
We're getting a SAN, whose initial use will be to house a few Oracle DBs. I'm proposing that our ERP DB's layout include this:
Redo 01 2 drives, RAID 1 Redo 02 2 drives, RAID 1 Control 01 3 drives, RAID 1 Control 02 2 drives on server, RAID 1 (in case of SAN failure)
I've been asked to prove why the Redos shouldn't be RAID 10, because the striping should allow for faster writes. I remember reading that this was nullified by the sequential nature of the writes, but I can't remember where I saw this.
Cary? Tim? Jonathon? Everyone else here that I forgot?
THX!
