If you have four physical NICs teamed and connected to a vSwitch with 20 VMs, is the traffic truly load-balanced across all four NICs?

There are several different load balancing options, and if you have a cluster with VMotion or Fault Tolerance, and if security or performance is a concern - and it certainly should be in a good design - then you'd want to isolate management traffic so the perfromance of your VMs isn't affected.

This is a very detailed guide (albeit for ESXi 3.5) that explains the intricacies of setting up vSwitches and port groups.

Out going traffic is load balanced by default  However to balance the load of incoming traffic, you will have to create a ether channel on the Physical switch port.

Normal Load balancing is normally 1 of 4 algorithms:
  • Route based on originating virtual port ID
  • Route based on IP hash
  • Route based on Source MAC hash
  • Use explicit failover order
With the arrival of 4.1 the virtual Distributed Switch also offers true load-based load balancing. See here: http://kb.vmware.com/kb/1022590
