DAG and Hyper-V Support

    Question

  • I'm trying to confirm whether Microsoft supports having one node of the DAG running as a Hyper-V guest and the other node as another physical server.  So, if we want to begin our Exchange 2010 implementation by creating a single VM, we have the option to later add another node to a DAG solution, whether that be another VM or a physical server. Based on my reading of the ‘Hardware Virtualization’ section, we could have one node of the DAG running as a Hyper-V guest and the other node as another physical server.  The caveat appears to be that live migration is not supported, so we would need to turn off that feature in Hyper-V.

    per Microsoft's 'Hardware Virtualization' section:

    • 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.
