Protecting the VI workload domain vCenter Server is important because it is the central point of management and monitoring for the VI workload domain.

VMware Cloud Foundation supports only vSphere High Availability (vSphere HA) as a high availability method for the VI workload domain vCenter Server.

Design Decision

Design Justification

Design Implication


Protect the vCenter Server appliance by using vSphere HA.

Supports the availability objectives for vCenter Server appliances without requiring manual intervention if a failure occurs.

vCenter Server becomes unavailable during a vSphere HA failover.


In vSphere HA, set the restart priority policy for the vCenter Server appliance to high.

vCenter Server is the management and control plane for physical and virtual infrastructure. In a vSphere HA event, to ensure the rest of the SDDC management stack comes up faultlessly, VI workload domain vCenter Server must be available first, before the other management components come online.

If the restart priority for another virtual machines is set to highest, the connectivity delays for management components will be longer.
