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 1. Traffic type settingsTraffic type settings for default network I-O control
Traffic type	NIOC shares
Traffic type	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.
