VMware pitches alternative to Microsoft Exchange 2010 DAGs

VMware HA monitors the virtual machine (VM) and can trigger a restart on another node in an ESX cluster should there be a failure. DAGs, in the meantime, work at the application level and allow for Exchange database replication, to protect application data in the event of a failure and to trigger failover should a failure occur at the app level rather than in the VM.
