Video - Load-Based Teaming (LBT) in action

vSphere 4.1 introduces a load-based teaming (LBT) policy that ensures vDS dvUplink capacity is optimized. LBT avoids the situation of other teaming policies in which some of the dvUplinks in a DV Port Group’s team were idle while others were completely saturated just because the teaming policy used is statically determined. LBT reshuffles port binding dynamically based on load and dvUplinks usage to make an efficient use of the bandwidth available. LBT only moves ports to dvUplinks configured for the corresponding DV Port Group’s team. Note that LBT does not use shares or limits to make its judgment while rebinding ports from one dvUplink to another. LBT is not the default teaming policy in a DV Port Group so it is up to the user to configure it as the active policy.
LBT will only move a flow when the mean send or receive utilization on an uplink exceeds 75 percent of capacity over a 30-second period. LBT will not move flows more often than every 30 seconds. This video will show Load-Based Teaming (LBT) in action.
