Hyper-V Cluster: Network Configuration

Management Network(Parent Partition)
1 Network Card

• Make sure this card is listed first in the Adapter and Bindings connection order.
• In Failover Cluster Manager make sure that the NIC is configured to allow cluster network communication on this network. This will act as a secondary connection for the Heartbeat.

Storage ISCSI
2 Network Cards – Not Teamed

• Enable MPIO.
• Disable NetBIOS on these interfaces
• Do not configure a Gateway
• Do not configure a DNS server
• Make sure that each NIC is NOT set to register its connection in DNS
• Remove File and Printer sharing
• Do not remove Client from Microsoft networks if using Netapp Snapdrive with RPC authentication
• In Failover Cluster Manager select- Do not allow cluster network communication on this network

VM Network
(Parent Partition)
2 Network cards :
1 for Dynamic IP’s
1 for Reserved IP’s

• Disable NetBIOS on these interfaces
• Do not configure a Gateway
• Do not configure a DNS server
• Make sure that each NIC is NOT set to register its connection in DNS
• Remove File and Printer sharing and Client from Microsoft networks
• In Failover Cluster Manager select – Do not allow cluster network communication on this network.

Cluster Heartbeat
1 Network Card

• Disable NetBIOS on this interface
• Do not configure a Gateway
• Do not configure a DNS server
• Make sure that this NIC is NOT set to register its connection in DNS
• Make sure that Client for Microsoft Networks and File and Printer Sharing for Microsoft Networks are enabled to support Server Message Block (SMB), which is required for CSV.
• In Failover Cluster Manager make sure that the NIC is configured to allow cluster network communication on this network.
• In Failover Cluster Manager remove the tick box for Allow Clients Connect through this network. This setting has nothing to do with the host/parent partition. This setting is used to control over what NICs the Cluster Resources can be accessed.

Cluster Shared Volume (CSV)
1 Network Card

• Disable NetBIOS on this interface
• Make sure that this NIC is NOT set to register its connection in DNS
• Make sure that Client for Microsoft Networks and File and Printer Sharing for Microsoft Networks are enabled to support Server Message Block (SMB), which is required for CSV.
• In Failover Cluster Manager remove the tick box for Allow Clients Connect through this network. This setting has nothing to do with the host/parent partition. This setting is used to control over what NICs the Cluster Resources can be accessed. This is more relevant for other workloads e.g. File Cluster. It has no impact on the communication with the host partition or for the VM’s themselves.
• By default the cluster will automatically choose the NIC to be used for CSV communication. We will change this later.
• This traffic is not routable and has to be on the same subnet for all nodes.

Live Migration
1 Network Card

• Disable NetBIOS on this interface
• Make sure that this NIC is NOT set to register its connection in DNS.
• In Failover Cluster Manager remove the tick box for Allow Clients Connect through this network. This setting has nothing to do with the host/parent partition. This setting is used to control over what NICs the Cluster Resources can be accessed. This is more relevant for other workloads e.g. File Cluster. It has no impact on the communication with the host partition or for the VM’s themselves.

• By default the cluster will automatically choose the NIC to be used for Live-Migration. You can select multiple networks for LM and give them a preference.
