You can configure Network I/O Control to allocate certain amount of bandwidth for traffic generated by vSphere Fault Tolerance, vSphere vMotion, and so on.

You can use Network I/O Control on a distributed switch to configure bandwidth allocation for the traffic that is related to the main vSphere features:

  • Management
  • Fault Tolerance
  • NFS
  • vSAN
  • vMotion
  • vSphere Replication
  • vSphere Data Protection Backup
  • Virtual machine

vCenter Server propagates the allocation from the distributed switch to each physical adapter on the hosts that are connected to the switch.
