vSphere Network I/O Control

Network resource pools determine the bandwidth that different network traffic types are given on a vSphere distributed switch. When network I/O control is enabled, distributed switch traffic is divided into the following predefined network resource pools: Fault Tolerance traffic, iSCSI traffic, vMotion traffic, management traffic, vSphere Replication (VR) traffic, NFS traffic, and virtual machine traffic.
