Network requirements for Microsoft Hyper-V Cluster

In this post describe physical networks configuration for hyper-v cluster. The below table shows minimum requirements for network in a Hyper-V cluster. Generally, two NIC with eight ports is require to configure hyper-v cluster networks with Teaming ( Network high availability )

Hyper-V Networks Description Type
Management Used for the Remote desktop, monitoring, backup, and Hyper-V management traffic all pass through this network by default. Public
VM Network Used to provide network access for VM’s .All VM’s network traffic will pass through this network Public
Cluster Heartbeat Private network to check the status of the cluster hosts Private
Live Migration Used to transfer the running VM’s from one cluster node to another Private

Other Recommendations

Dedicate VLAN for each networks

Network teaming is recommended for all networks . So two NIC with eight ports is required. In addition more VM’s network can be added based on the through-put and networks requirements such as DMZ,..Etc

Management networks should be first i in the Adapter and Bindings connection order. Then heartbeat and failover network .

Do not configure a Gateway and DNS for Heartbeat and failover networks.

Disable file and print sharing for VM networks and not require to set IP’s
