Our department used Vsphere Operations Management as a solution for disaster recovery in our environment. It was only used by a few people here on our staff. This did solve our plans for server recovery in a way that is automated. It basically scripts the powering on of replicated virtual machines into a different network.
vSphere with Operations Management has a much better way of automating the re-IPing of servers so you can stand them up in a different environment or location. You do, however, need another way of replicating your servers to your DR site, VSOM will not do that. We used EMC Recover Point for replication.
Vsphere Operation Management is suitable for automating the process of bringing up an alternate data center in case of a disaster. It also is a great way for testing your readiness of disaster. You have the ability to bring up a server in a "bubble" for testing. This way you can show your admins how the failover process will work.
