I am currently planning a high available Windows Server 2012 R2 environment within a Hyper-V-Cluster with two nodes. I am not sure about how to deploy the virtual domain controller for the work domain, to keep the forest available when a node goes down.
I see two options:
Create one virtual machine with the domain services and configure the vm as a cluster resource in the failover cluster. Let the cluster worry about the availability of the virtual machine (domain controller).
Create one VM on Hyper-V-Node 1. Create a second VM on Hyper-V-Node 2. VMs are not configured as a cluster resource (no redundancy per VM). Install domain services on both VMs. Let the domain controllers worry about offering the domain services, if a node and therefore one VM goes down.
My Questions are:
- Is there a preferred method?
- What advantages and disadvantages do both methods have?
I appreciate high quality answers, please back up your responses with sources.
