How to use 4 NICs for making high available 2 node hyper-v 2012 cluster RRS feed

  • Question

  • Hi,

    I have 4 NICs on my server and I need to setup a 2 node highly available HYPER-V 2012 cluster with connectivity to SAN using iSCSI.

    Please let me know the best way I can do this, as if I do teaming then i am running out of NICs for required setup. How about if I use 1 NIC team for cluster, management, live migration and another NIC team for iSCSI SAN? Is there any drawback in using single NIC for cluster,management and live migration?

    Thanks!!

  • Hi,

    For a Hyper-V cluster scenario, we recommend that you configure separate dedicated networks with gigabit or faster speed for live migration traffic and cluster communication, and these networks should be separate from the network used by the management operating system, and from the network used by the virtual machines.

    We recommend that you do not use the same network adapter for virtual machine access and management. If you are limited by the number of network adapters, you should configure a VLAN to isolate traffic.

    It is recommended that all network configurations should isolate cluster/Cluster Shared Volumes and live migration on private networks.

    What’s the network speed of your 4 NICs? 1Gbps or 10 Gbps?

    The following table details the recommended, supported, and not recommended network configurations for live migration, and is organized in the order in which each network configuration is commonly used. Before reviewing the table, note the following:

    Host configuration

    Virtual machine access

    Management

    Cluster and Cluster Shared Volumes

    Live migration

  • thanks for replying Ortac, but I mentioned i'll be using NIC teaming...which reusult in providing me aggregated 2 NICs for use. Thus how can I use 2 NICs for all this stuff?

  • Ms does not support NIC teaming for iSCSI. You can use NIC teaming for management, live migration and others.

  • thanks, How about if I use 1 teamed NIC  for all ....cluster failover, management, live migration, Is there any drawback in using same NIC for cluster,management and live migration?

  • You can use 1 NIC teaming for all. I used only one teaming for many cluster. There is not any problem. But MS offers at least two seperate network adapter.
