SRDF is a nice technology but comes with a premium. To replicate 1TB of
storage, a total of 4TB is required (source + R1 + R2 + target);
something to be kept in mind. It also requires a higher bandwidth when
compared to other replication technologies like Symantec's VVR and EMC's
Recover Point.

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.
Thoughts?
