Default network I-O control (NIOC)

Default network I-O control (NIOC)

  • VxRail enables network I-O control on the VMware VDS and configures custom Network I-O Control (NIOC) settings for the following network traffic types.

    The settings depend on whether the VxRail cluster was deployed with either two Ethernet ports per node that is reserved for the VxRail cluster, or if four Ethernet ports were reserved for the VxRail cluster:

    Table 51. Traffic type settings
    Traffic type NIOC shares
    Four ports Two ports
    Management traffic 40 20
    VMware vSphere vMotion traffic 50 50
    vSAN traffic 100 100
    VM traffic 60 30

    The reservation value is set to zero for all network traffic types, with no limits set on bandwidth.
