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?
