Looking for thoughts and best practice for replicating and dealing with restoring an environment after disaster strikes. We have a DR facility with a high bandwidth pipe. Replicating AD to this site would not be difficult, but what happens when your primary site evaporates into thin air and you need to bring up the same server infrastructure at DR? We have the ability to Snap mirror (replicate) data in near realtime via SAN and we are heavily virtualized. What I'm struggling with is the naming and IP addressing of the identical servers at DR. I'd be interested to hear how others are tackling this issue? Assuming that in the event of Primary site failure, the DR site must quickly assume all critical server roles, names and IP addresses.
