Our NetApp , with its WAFL file system, is very easy to backup. We take the DBs down for 5 minutes (time enough to take a snapshot) and then bckup the snapshot to tape ... or make standbys .... or whatever.

As for a poor mans version of HA ..... we have multiple servers tied into the NetApp. If one server fails, we just start oracle on the other server with an exact home. The users are only interupted for a short period of time.

I've been speaking to Veritas people about this lately.

They don't like NetApp because it is difficult to backup.

Veritas likes to have some hooks into the Filesytem, and apparently this isn't easy to do with WAFL for some reason. ( WAFL is the NetApp Filesystem )

Veritas doesn't sell hardware, so they don't have any $$ incentive for preferring one over the other.

They do on the other hand find SAN's very attractive. There's a lot of capabililty in a SAN for HA and management that is lacking in NetApp.

You might try talking to your local Veritas Sales and Support critters, they always like to get phone calls. :)

        Subject:        Oracle and NAS storage systems

Folks,

I've been asked to validate/invalidate a contention made by two storage
vendors.

NetAppliance has stated that you can use a netapp filer with Oracle for
datafiles, although their configuration looks more like a DAS(direct attached
storage) configuration using 10baseT cables vs. SCSI cables. Of course their
real claim to fame here is Oracle's endorsement.

EMC on the other hand has stated that using a NAS, in the traditional mode,
for Oracle datafiles is at best risky. And although their product can support
it, they do not recommend doing so for several of the reasons that I've held out
are pertinent.

Therefore, is there anyone out their using a NAS to store datafiles? If so,
what does the configuration (server to NAS) look like?
