Network I/O Control Version 3 allows administrators or service providers to reserve or guarantee bandwidth to a vNIC in a virtual machine or at a higher level the Distributed Port Group.

NIOC[1]

This ensures that other virtual machines or tenants in a multi-tenancy environment don’t impact the SLA of other virtual machines or tenants sharing the same upstream links.

Use Cases:

  • Allows private or public cloud administrators to guarantee bandwidth to business units or tenants. –> This is done at the VDS port group level.
  • Allows vSphere administrators to guarantee bandwidth to mission critical virtual machines. –> This is done at the VMNIC level.
