We have a Hyper-V cluster running on Windows Server 2012 R2. Each server has 8 1-GBit-NICs. Four of them are used for guests, 1 for the cluster network, 1 for the management network, and 2 are currently unused.
Is there a way to use one or two additional NICs to speed up Live Migration?
I tried to configure an additional NIC to the management network (on all nodes) - still, it is not seen by Failover Cluster Manager (it shows the management network with 1 NIC and the cluster network with 1 NIC). Can I make it see the additional NIC, and, more important, would Hyper-V use it for Live Migration then?
Can I use NIC teaming? Or would Hyper-V still use only one TCP connection for Live Migration and hence employ only one of the teamed NICs?
Or should I just be happy that Live Migration is so much faster than in Server 2012 and keep my mouth shut ;)
