Network I/O Control (NIOC) has the ability to detect system traffic type and control its bandwidth usage based on shares, reservations, and limits.
There are nine system traffic types as shown in the following list:
- Fault tolerance traffic
- Management traffic
- NFS traffic
- Virtual machine traffic (this needs to be enabled)
- Virtual SAN traffic
- iSCSI traffic
- vMotion traffic
- vSphere data protection backup traffic
- vSphere replication traffic
System traffic types don't have any reservations by default. However, we are allowed to set a reservation on each of the traffic types by editing their settings.
User-defined network resource pools allow further segregation and control over the VM traffic detected by the NIOC. In this recipe, we will learn how to create one.
