VMware ESX does not include native support for NFS I/O load balancing. An NFS export is mounted on
the ESX host via a VMkernel NIC port (vmknic). To enable this, a vmknic port configured with an IP
address on the NAS client subnet is assigned to a vSwitch. Physical NICs on the host which are
attached to the NAS client network are mapped to this vSwitch as uplinks. All NFS traffic passes
through this single vmknic from the hypervisor. ESXi vSwitches are designed such that, even if we
create multiple vmknic ports (on same or multiple vSwitches), by default the first created vmknic port
on the NAS subnet is used for all traffic on that subnet. This traffic on the vmknic port in turn gets
mapped to a single uplink (physical NIC) configured on the vSwitch if a port based or MAC based load
balancing policy is used on the vSwitch (See Figure 4 below).
