Title: RE: DBA Experiences with Oracle and RAID 0+1

If I remember correctly, I do not think that chapter covers RAID.  There is a good white paper on implementing RAID for Oracle at http://www.quest.com/whitepapers/Raid1.pdf

Cheers,
Craig.

Jon:

I would suggest "Oracle8i DBA Handbook" by Loney & Theriault.  Chapter 4
deals with the physical database layouts.  It starts with the ideal layout
on 22 disks and goes down to about 7 disks.  It's very good.

We are in the process of setting up a SAN using RAID 0+1 for our database.
In our current environment, we are able to separate our tables, indexes,
rollback segments, and archive logs on different disks.  On the SAN we would
have six 73 gig disks on RAID 0+1 for a total of about 210 Gig of usable
space (3 disks worth of space).

Some white papers that I have read suggest attempting to separate the data,
indexes, and rollback segments on separate RAID volumes, and others simply
suggest that the performance boost of striping will supercede the separation
of these items.

Can anyone offer any comments or suggestions?
