HP CA does, and all storage-based replication products do at this point.

You need to make sure that whatever product you use maintains write-order
fidelity otherwise the replication will be no good.

We're getting off track here a bit...I'm not really interested in EMC
SRDF. I targeting the HP Continous Access (CA) product on an EVA 8x00 SAN.
I'm hoping someone "out there" is doing this and is on this list :)

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?
