Exchange Server DAG mailbox server VMware network configuration
I'm about to deploy Exchange Server 2013 SP1 in a DAG configuration on VMware ESXi server DRS cluster.
As per my understanding, the requirement is 2x vNICs:
1x vNIC - RPC over HTTP (Outlook client connection)
1x vNIC - DAG replication between servers (separate VLAN or IP address class or non-routable)
So my question is that, do I need to use 2x vNIC like the above or can it be just one vNIC ?
If two vNICs is required, How do I configure the vSwitch on each of the ESXi servers in DRS cluster so that the secondary vNIC that is only used between DAG mailbox server can still be functioning in the event of vMotion or Fully automatic DRS rebalancing.
