We are evaluating storage expansion for our Oracle
databases. I have been asked by my Unix SA what my
preference is between the following.

My gut tells me to select SAN, but I need some doco to
back me up.

Oracle best performance on:
NAS - Network Attached Storage - I think this is bad
NFS - NFSmounted - I think this could be even worse
SAN - Storage ArrayNetwork - YES (like StorageTek,
EMC, etc)

I am looking for doco that supports the best decision
and your opinion. We will soon have several instances
up to 250 GIG, OLTP and DSS.

Thanx for your time :)!
