So it's being set up as a Virtual Tape Library rather than a SAN... No
difference either way really (other than the way the channels get allocated,
ie. tape versus disk). The backup/restore times would be greatly improved over
traditional tape storage.

to the post but have been reading them for at least two years. I hope I am
replying to these in the proper manner.

EMC Rep told us the dedup device would present itself to RMAN as a 'TAPE'
device. Our current ATA SAN disks are 'DISK' devices in RMAN.
Any perceived disadvantages to that? Sorry I am not an RMAN guru.
