Hi everyone,

Is there any max latency requirement by VM ware between Primary and Secondary machine when it comes to Fault tolerance?

Thanks and have a good evening!!

It requires low latency and a 10 Gbps network. There's no latency requirement published because it's meant for localized workloads. FT is absolutely not designed for WAN-disparate hosts and you should not attempt to use it in such a scenario.

the requirements, as mentioned above, are also documented here:
