summary of hyper-v / cluster networks required

    Question

  • hello are these all the networks required for hyper-v cluster with server 2016?

    mgmt (default vlan)

    virtual machine network (default vlan)

    live migration network (isolated vlan)

    cluster network (isloated vlan)

    iscsi network (isloated vlan)

    did i miss anything?

  • Correct, that is the recommended network configuration.

  • is it possible to run these networks on 2 physical 10G NICS?

    Do we need to use powershell somehow to configure the qos or simliar?

    Except ISCSI of course.

  • Hi,

    Thanks for your question.

    We could try this blog (https://www.altaro.com/hyper-v/architect-networks-hyper-v-cluster/ ) to implement to see if it meets your need.

    There’re the options for hosting a cluster network:

    1. One physical adapter or team of adapters per cluster network
    2. Convergence of one or more cluster networks onto one or more physical teams or adapters
    3. Convergence of one or more cluster networks onto one or more physical teams claimed by a Hyper-V virtual switch
    • For modern deployments, avoid using one adapter or team for a cluster network. It makes poor use of available network resources by forcing an unnecessary segregation of traffic.
    • I personally do not recommend bare teams for Hyper-V cluster communications. You would need to exclude such networks from participating in a Hyper-V switch, which would also force an unnecessary segregation of traffic.
    • The most even and simple distribution involves a singular team with a Hyper-V switch that hosts all cluster network adapters and virtual machine adapters. Start there and break away only as necessary.
    • A single 10 gigabit adapter swamps multiple gigabit adapters. If your hosts have both, don’t even bother with the gigabit.

    It is recommended that you start off expecting to use a completely converged design that uses all physical network adapters in a single team. Create Hyper-V network adapters for each unique cluster network.


    If you have any question or concern, please feel free to let me know.

    Best regards,

    Michael

    Yes, this is possible with converged networking, but with Windows Server 2016 RDMA is recommended. If you do not have RDMA capable network adapters, check this link
