Hi Kelsey, HA is at 2 levels – VMs can be marked HA. In addition, you can mark some hosts as reserved for “Dedicated” HA hosts. Quoting from the manual, the dedicated HA option is set through a special host tag when the host is created. To allow the administrator to dedicate hosts to only HA-enabled VMs, set the global configuration variable ha.tag to the desired tag (for example, "ha_host"), and restart the Management Server. Enter the value in the Host Tags field when adding the host(s) that you want to dedicate to HA-enabled VMs.

Thanks.
