In my opinion, SAN storage begs the question about whether OFA makes sense anymore. If you can configurte the SAN storage so that all files are striped across all disk, then everything is spread. And if the SAN is mirrored, then just why are we working so hard?
EMC SAN disk has such an incredible uptime, that worrying about losing things like control files are (almost) a thing of the past.

How do you ensure that control files and redo log files are kept safely apart so that no one disk failure in the shared storage can take them all out? According to the OFA(well the abbreviated version I have in front of me) 4-5 disks is optimal for multiplexing. Does this no longer apply with shared storage? How do you ensure database available with shared storage? if your not multiplexing datafiles? I may have read some peoples posts incorrectly. Im just digging into backup and recovery. -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: <[EMAIL PROTECTED] INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
