Looking for tips as to laying out an Oracle DB on a SAN. I assume you probably want the fastest I/O for the redo logs and temp? The SAN I am working with has LUNS are carved up out of 10 or so disks on RAID5. Does it matter if we put the archive logs and the datafiles on the same LUN? Are these kinds of questions better suited to the SAN expert? Assuming I can defer a lot to the SAN expert, what I/O requirements and path requirements should I provide them? Centralized storage is centralized storage so I'm not sure how to parse things out. I also realize a lot of this may depend on the kind of SAN and its particular characteristics, but are there generic rules that can be provided?
