When you are using NIOC v3, you can manage the network resources, such as shares, reservations, and limits, in a similar way to resource pools for computing. NIOC is a vDS-only feature that allows the VMware administrator to prioritize different types of network traffic.

Network traffic can be managed using the same resource concepts used for CPU and memory (for example, in resource pools):

  • Limit: The maximum bandwidth that a system traffic type can consume on a single physical network adapter.
  • Shares: From 1 to 100 reflects the relative priority of system traffic type against the other system traffic types that are active on the same physical network adapter. Shares are applied only when the congestion occurs.
  • Reservation: The minimum bandwidth that must be guaranteed on a single...
