run the engine as “highly available”, you will need at least two Hosted Engine Hosts in your setup. One, however, is enough to host the engine, but you will lose the ability to migrate the engine to another server, if you need to maintain the Hosted Engine
Host.<o:p></o:p></span></p>

<p class="MsoNormal">Same thing, the engine in this case is "self-hosted", as in, it runs in a VM hosted on the cluster that it is managing. I am a beginner here, but from my understanding, each node is always checking on the health of the engine VM. If the
engine is missing (ie, the host running it has gone down), then another available, healthy host will spawn up the engine and you will regain access. <o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">In my experience this has worked very reliably. I have 2 hosts, both are "able" to run the engine VM. If I take one host down, I am not able to load the engine GUI. But if I wait a few minutes, then I regain access, and see that the
engine is now running on the remaining healthy host. <o:p></o:p></p>
