VMware has introduced LBT to resolve this problem in particular. As you can tell few vms in your environment can make up the majority of network traffic load in your environment and if these all landed randomly on the same vNIC that vNIC can be over loaded and your vms will perform poorly although you have other vNICs that almost idle. Looking at the above image, you can understand that load balancing policy such “Route based on the originating Virtual Port ID ” & “Route based on MAC addresses” can end up with more heavy load on one of your vNICs rather than the other vNICs as the mapping between the VM & the vNIC is fixed and does not consider the load the NIC has it just consider how many vm each vNIC has and it make sure that they are distributed evenly across vNICs though without taking into consideration the amount of load each vm is generating. While this cut it well in normal scenarios, there is scenarios where this can cause a problem. The way “Route based on the originating Virtual Port ID” & “Route based on MAC addresses” distribute VMs network load across your uplinks by distributing the number of VMs evenly across all the vNICs involved in the team. Imagine you are using a virtual switch with the default setting of “Route based on the originating Virtual Port ID” or “Route based on MAC addresses” for the teaming load balancing policy. The easiest way to see how beneficial LBT can be is to look at the problem it solve. For these reasons, I have decided to share why the Load Based Teaming feature offered within our Distributed switches is a great feature and can be of a great use to many of you out there. Many of them already have the Enterprise Plus license which include LBT in it, & its just a matter of enabling to start benefiting of it. What surprise me the most that many of these are in a desperate need for a similar feature. It is really common to see customers who never get their hands or heads around LBT. As part of my job in consulting, I get to see many customers environments through out the year. VMware load based Teaming (LBT) is one of the great feature that was introduced a while back with vSphere 4.1, though it seems many admins have over looked it.
