Hey Tom,
 
I'm in the same boat.
 
Have you looked over some of the red papers at www.storage.ibm.com/ess???
 
If not, check this one out...
 
Storage Management for SAP and Oracle8i on SUN SOLARIS Split Mirror Backup/Recovery with IBM's ESS.
 
Granted its for Solaris, but I would think the concepts are the same.  And of course, there are more about Oracle.
 
I believe were running RAID 5, which has me a bit concerned being a unofficial member of the BAARF organization.  The red papers speak to this problem, and supposedly it has been resolved.  Something about the entire stripe being cached.  Since I'm a SAN newbie, I'm starting with the Introduction to SAN paper, and reading my way up.  I don't want to raise a red flag until I can prove it.
 
Please keep me in mind with whatever path you take.  And if you present your findings let me know, I would love to read'em.
 
Thanks.
 
Chris

Gene,
 
What happens when you need to perform a recovery from the Flashcopy backup? 
Is Flashcopy done while the database is open or closed?
If the database is open, then I assume that you would need to perform an incomplete recovery?

Just curious.  I am in the middle of setting up new IBM/AIX boxes, and we will using either EMC or IBM Shark disk.  Flashcopy was mentioned as a possible solution for backups.  But I don't like being boxed in to performing an incomplete recovery.

I don't use snapshots, but have used EMC BCV's in the past and now use IBM's Flashcopy for backups.  I backup 1TB db in ~20 mins using Flashcopy.  Then I take it off to tape, i.e. filesystems monted on a TSM Backup server, hence no resources needed from the production server :).

We are implementing Oracle RAC on two Windows nodes, connected to an EMC
SAN. We'll also have a failover sight.

We are using S.A.M.E. disk configuration, with only one logical volume,
and backups/archivelogs dumping to another volume.

The SAN is an EMC Clariion CX400.

I immediately vetoed snapshots, opting for RMAN, but I'm now taking a
second look.

Does anyone use the snapshot technology as a solution for full backups?

Thanks,

Jeff
