Hyper-V 2019 Networking Best Practices

Question

Hi,
We are setting up a Hyper-V (Windows 2019 Datacenter) cluster with 4 nodes.

Each node (Dell PowerEdge) has 6 network cards:

• Two 10 gb iSCSI for the storage network (EqualLogic)
• Four 1 gb NICs for the networking

What is the optimal setup for the networking part (management, live migration, cluster) of the implementation?

Hi,

Thanks for your post!

Generally, we have the following cluster network types in the Hyper V cluster: Management, Live migration, Cluster, and Storage.

I would suggest you configure the network settings below:

1. Management Network: Two 1GB NICs to configure NIC teaming, in Cluster network, check "Allow Cluster network communication on this network" & "Allow clients to connect through this network".
2. Live migration Network: One 10GB NIC, in Cluster network, check "Allow Cluster network communication on this network" & "Allow clients to connect through this network"; In live migration settings, put this network in the first order.
3. Cluster Network: Two 1GB NICs to configuration NIC teaming, in Cluster network, check "Allow Cluster network communication on this network".
4. Storage Network: One 10GB NIC, in Cluster network, Check "Do not allow cluster network communication on this network".
