Disaster Recovery Site HYPER-V Hosts and Domain


I am in progress to install a Disaster Recovery Site with HYPER-V. The HYPER-V Hosts in Disaster Recovery Site want to be with Failover Clustering.

But to use Failover Clustering must be a member of a Domain,

So i must create a new domain name in Disaster Recovery Site for my HYPER-V Hosts? or must use the same as in Production?

I talk only for the HYPER-V Hosts not for the Virtual Machines.

Site-to-Site VPN set up between the DR site and the main site would be one way to do this.

Another would be to set up a DC on the Hyper-V host's local storage, configure a greenfield AD, and then set up a second DC on another node's local storage to provide some redundancy.

We always deploy a DC in cluster settings.

Hi Philip,

I understand all these.

But my question is HYPER-V Hosts in Disaster Recovery Site must be join in domain of production environment?
Philip ElderTechnical Architect - HA/Compute/StorageCommented:
No. They don't have to be in the same domain as the VMs being replicated to them.

I would make things simpler management wise if they were though.

The Hyper-V hosts need to be in the same domain as the hosts they are replicating from for the failover clustering to work.  

Virtual machines would not need to be in the same domain as the hosts.  Often they will be though.
Philip ElderTechnical Architect - HA/Compute/StorageCommented:
@John Hyper-V replica can be set up to run between systems and clusters in the same domain or not.

Once a cluster is stood up a DC is not required for a cold-boot though one is required at some point down the road.
