Hyper-V Networking - Should I team 4 10GB nics and do the vlans through virtual switch? RRS feed

  • Question

  • I am building out a new cluster and would like assistance with the internal networking. There are four vLans, Data, iSCSi, Live migration and CSV/heartbeat.

    I have four 10GB links and four 1 GB links

     

    Specifically, how do I configure the four 10 GB links to provide the best utilization? Can I team them and use a virtual switch? Should the  1 GB links be used?

     

    Thanks

  • Hi,

    you should not team iSCSI NICs (use MPIO instead)

    you should not team VM NICs (use SET instead)

    you should team cluster heartbeat and management.

    So based on that, what I would do is this:

    • 2x 10G connected to different switches attached to the same vSwitch using SET for VM traffic.
    • 2x 10G connected to different switches for iSCSI with MPIO configured. Depending on what your iSCSI SAN offers in terms of targets, I would prefer giving the two NICsa addresses in different subnets.
    • 2x 1G connected to different switches as a team for management
    • 2x 1G connected to different switches as a team for cluster heartbeat

    For CSV, I would use the iSCSI network (same physical interfaces); for Live Migration, virtual NICs attached to the switch with the VM traffic and provided with a bandwidth limit.
