Hyper-V networking

Hi there,

We have a 3 HP blade servers each with 4 network adaptors avaliable that we would like to use as a Hyper-V failover cluster The shared storage is SAS connected so no need to use any adaptors for iSCSI etc.

I have been looking for a while and I can't find the best way to configure the networking in this configuration.

Ideally we want to use 1 NIC for management, 1 NIC for VM traffic, 1 NIC for heartbeating and one for other cluster traffic.

Is this possible and if not what is the best configuration for 4 physical NICs per host in Hyper-V?

    This is definitely possible, but a better config may be this:

    1 NIC - Management OS
    2 NICs - Dedicated VM traffic - Keep the same names across all Hosts so failover works properly, and you can balance traffic this way between VM's (Done via Hyper-V Manager)
    1 NIC - You can put CSV and Live Migration  traffic on the same nic. Heartbeat/CSV chatter/traffic is not very much. The only time you will have LM traffic is when you live migrate. Put this on it's own subnet. it is important you segment it away from your primary production network.

    The Cluster creation process will create the cluster networks based off a detection process. you have to assign IP's and connect your networks appropriately. I use a small 8 port gig switch that is jumbo frame capable for my cluster network, so that the network is separated from my production network. I believe it is a TRENDnet switch. doesn't have to be fancy. The process will detect this network. You can adjust what networks are used for cluster communication and live migration in the Failover Cluster Manager process. I use the private switch network for Live Migration, but you can also use the management network as well. Hyper-V fails over if the first network is unavailable, based off the order you set.

    Here are some of the resources I used during my implementation:
