EMC just announced that they are adding automated failbacks to SRM for their Celerra family via a vCenter plugin. I hope I can see a demo here at VMworld:
VMware Site Recovery Manager Automated Failback via a VMware vCenter plug-in helps Celerra customers coordinate a “failback” to the original virtual infrastructure, including all the process steps once VMware Site Recovery Manager performs a failover. EMC offers the only solution on the market today that arms customers with end-to-end disaster recovery at the simple push of a button.
