I've been digging around trying to figure out if Exchange 2010 using DAG between two servers is supported (or un-officially supported) running as guests VM's on a 2 node 2008 R2 Hyper-V HA cluster in a production environment (very small though, 20 mailboxes).
Everything seems fine until I get to this part -
"Microsoft doesn't support combining Exchange high availability solutions (database availability groups (DAGs)) with hypervisor-based clustering, high availability, or migration solutions. DAGs are supported in hardware virtualization environments provided that the virtualization environment doesn't employ clustered root servers."
I find this very odd is this would also exclude VMWare ESX hypervisor using vmotion as well, which is just strange.
Anyone know anymore about this?
