Hyper v cluster domain controller best practices

I am trying to setup hyper v cluster for first time. I am setting up an active-active high availability iscsi failover. So I have two hyperv servers and two San servers and two switches.

I have an existing network called domain1. All my workstations and vms will be on this domain.

The instructions I have say that I need an active directory server for my hyperv clusters.

I realize I need a private network for all my and replication connections, however do my hyper v servers need a dedicated domain controller? Or Does the private network for iscsi connection and replication need aidomain controller?

Or could I use my existing network domain controller on domain1? For the hyperv servers....and no domain controller for the private network?

Best practice is to have a network where your servers and workstations reside and the host servers need to be on this network.   Networks for iSCSI, replication, heartbeat and live migration do not need a DC.

How we would set this up:

SANs <--> Switch 1/2 via MPIO <--> Hyper-V Hosts <--> Switch 3/4 <--> Production Network

Keep your storage traffic isolated from your production network.

Then, there is the question of where to put your Live Migration traffic. If LM is to be a regular thing then a dedicated switch or switches would be a good idea unless your storage is 10GbE/40GbE. You If yes to high performance then VLAN for LM.

As to your specific question we _always_ have a physical DC on our cluster based setups. We also run a DC within the cluster.

Why a physical DC since it is not required to cold-boot the cluster?
 + AD may be needed in the event of a cluster failure
 + DNS IS required in the event of a cluster failure
 + Physical DC is our time authority (Critical in a virtualized environment especially with high-load VMs where time skews)
 + Point of management in the event of a problem

Those are the ones that come off the top. :)
