We use native Exchange 2003 clustering (on Windows 2003 EE servers) in combination with an EMC SAN. A basic SAN will give you immediate failover if there is a hardware problem with one server. In addition, we have 2 SAN disk arrays that are mirrored using EMC's MirrorView. If we lost the building, we could promote the data (LUNs) on the remote side to primary and bring up the server there in a matter of minutes. The way we have that setup is one server and one disk array at our primary site and one server and one disk array (mirrored, no access during normal business conditions) at our remote location. Mirrorview commits the write on both disk arrays before the server gets a write success notification, so the data is mirrored in realtime. This is not an inexpensive solution, and it does require a high speed connection between sites (fiber). It works very well for us.

I'm thinking some kind of failover to another system in another building, maybe even another city! I doubt anybody will have the $$ to pay for such a solution, but they're asking for it, so I need to at least give them some choices. A simple Google search turns up dozens of possibilities. What do you folks use, and are you satisfied with your solution?
