I am in the processing of building a 3-node Hyper-V cluster for our disaster recovery site. I'm not sure if I will use Hyper-V replica to keep a small subset of VMs available or if I will use our SAN replication to make them available. I'm trying to figure out what I will need in terms of network connectivity. The servers have 4 NICs and no open slots on the riser card for expansion. All VMs will be on the same subnet and they will only be active in the event of a site failure at our main datacenter. The SAN is connected via FC and there is no need for iSCSI connectivity. Will the 4 NICs be sufficient and can somebody provide me with a list of what roles each NIC would need in this configuration?
Thanks!
