DPM and SAN

Is there any benefits if you have your data in SAN and use a DPM to protect it? For sure it has.

Lets say you have Exchange data stored in a SAN, and you would like to protect using DPM. If your Exchange is running on CCR (Cluster Continuous Replication), you will be able to backup DPM from a passive node.

Few things for you to start with if you have a SAN:
(NOTE: you will want to ask from your SAN vendor about the features that you can use/supported using DPM)

1) Replica. As the first replica of your DB/Data, you can make use of the "clone", this will save your time and performance from getting the data from the original server through a network.

2) Recovery. You can make use of SAN based recovery in DPM. What this will do is, instead of recover through network, you make use of SAN based recovery, this will save your network bandwidth as well as time to recover.
