Differentiating Network I/O Control capabilities
You can use NIOC on a distributed switch to configure bandwidth allocation for the traffic that is related to the main vSphere features:
- Management
- Fault tolerance
- iSCSI
- NFS
- vSAN
- vMotion
- vSphere replication
- vSphere data protection backup
- Virtual machine
For the different versions of NIOC, see the Explaining NIOC capabilities section.
Note that NIOC v3 does not support SRV-IO, CoS tagging, and user-defined network resource pools.
Regarding NIOC and other vSphere features, DRS can migrate VMs within a cluster of vSphere hosts to accommodate bandwidth reservations assigned to VM ports.
