The Network I/O Control (NIOC) is a vDS functionality that can manage the network bandwidth usage of system traffic types based on shares, reservation, and limits. NIOC is currently at version 3 and was released with vSphere 6.0. There are different types of system traffic management: FT, vMotion, VM, iSCSI, NFS, vSphere replication, vSAN, and vSphere data protection. The following is a screenshot of the different types of system traffic management:
By default, system traffic has no reservation. However, you can set a reservation on the virtual machine traffic type and then further segregate the bandwidth by creating network resource pools. These user-defined network resource pools are then mapped to dvPortGroups.
In this recipe, we will learn how to create user-defined network resource pools.
