Scenario1: NSX Edge configured HA disabled (1 appliance) and on that 1 appliance is activated "Fault Tolerance". They are on different datastores and different hosts.
This is unsupported configuration. FT on Edges is not supported, you should ECMP enabled Edges for such use cases.
Scenario2: NSX Edge configured HA enabled (2 appliances). They are on different datastores and different hosts.
This is the supported way of achieving Active-Standby HA for NSX Edges.
Hello, thanks for your answer. Can you be more detailed about "unsupported"? What will go wrong?
I`ll take a look at the ECMP with two edges. Any good "how-to" for that?
I'm sorry, i can't comment on what will go wrong when we are leveraging unsupported features/deployments . FT for workload VM's , don't do FT on Edges .
