    VSphere topology recommendation

      Dear Sirs,

       

      I am planning to deploy 3 powerful physical servers acting as esxi hosts, I have a SAN storage acting as a datastore for the hosts.

      I want to install vcsa on one of the hosts to configure HA but I am confused if the server hosting the vcsa is down, what happens?

       

      Do the other VMs on that host go up on the other hosts along with the vcenter?

      Or do I have to install vcsa on more than one host to ensure full HA?

          vSphere HA works regardless of whether vCenter is up and available or not. From HA's perspective, it's just like every other VM. And all VMs on the failed host, including vCenter, will be restarted elsewhere in the cluster.

           

          Or do I have to install vcsa on more than one host to ensure full HA?

          You would only be able to do this with vCenter HA (vCHA) and only if your license permits.
