vCenter High Availability (vCenter HA) protects not only against host and hardware failures but also against vCenter Server application failures. Using automated failover from active to passive, vCenter HA supports high availability with minimal downtime.
|Automatic||The automatic option clones the Active node to the Passive node and witness node, and configures the nodes for you.
If your environment meets the following requirements, you can use this option.
|Manual||The manual option offers more flexibility. You can use this option provided that your environment meets hardware and software requirements.
If you select this option, you are responsible for cloning the Active node to the Passive node and the Witness node. You must also perform some networking configuration.
