NetApp? Replace a SAN with a NAS box?
More than likely, they are using is EMC's SRDF (assuming it's on a Symmetrix) in asynchronous mode for replication. When that is done, a "snapshop" can be made on a BCV volume, which is then replicated to the secondary Symmetrix for playback onto another BCV, then to the R2 device. Since the BCV is a complete copy of the volume, there is a huge difference between doing that and making a simple snapshot on a NAS box.
And besides, I have never met a database administrator that DIDN'T jump and scream "IT'S THE STORAGE THAT DID IT!" when something went wrong. It's something in their genes that makes them blame the hardware.
NetApp? Puh-leeeze.
Biting the hand that feeds IT
