RE: Replicating Live Oracle DataFiles/LUNs to remote site via SAN tool?

I agree that there are a lot of concerns around synchronous replication of datafiles, but certainly, this is pretty much the gold standard in large database shops. Probably every one of my large customers uses something like SRDF for their DR.

I think that Data Guard offers many advantages over storage level replication, but it is indeed reliable, time tested, and works across any application technology, making it easy to sign off on as a DR solution.

We use EMC's SRDF method for replication/backups/refreshes. I'm fairly new to it, but as far as I can see, it's reliable and unbelievably fast. I've seen a full refresh of a 1.7 TB database finish in less than 2 hours. The refresh was taken from a running instance.

Cons - It's expensive....

Any of you guys/gals replicating LIVE datafiles from one SAN to another in a remote location?

We're looking at using HP's CA tool to replicate LIVE datafiles across a WAN to another SAN. The replication is block based, so any block that changes on the primary LUN is immediately replicated to the remote LUN at the remote site.

Is anyone doing anything similar to this? Pros? Cons? I have a hard time imagining that this is a good idea but perhaps it is doable.
