The configuration of the FT is a simple process. It is performed on the individual VM level.
As FT traffic might generate a significant amount of bandwidth, it is highly recommended you use a dedicated physical network interface card for such reasons. If you are not able to dedicate a NIC for FT traffic, you should consider using other Quality of Service (QoS) features such as Network IO Control to guarantee specific bandwidth to different traffic types on the shared physical media.
In both cases, prior to configuring the FT on the VM, you need to configure a VMkernel port that will be used for FT traffic and enable the Fault Tolerance logging service on the adapter. Again, it is highly recommended you use a dedicated VMkernel ...
