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!
