The system administrator, as the SuperUser, manages all aspects of the Administration Portal. More specific administrative roles can be assigned to other users. These restricted administrator roles are useful for empowering a user with certain administrative privileges that limit them to a specific resource: a DataCenterAdmin role has administrator privileges only for the assigned data center, a HostAdmin has administrator privileges only for the assigned host, and so forth.

A host administrator is a system administration role for a specific host only. This is useful in clusters with multiple hosts, where each host requires a system administrator. You can use the Configure button in the header bar to assign a host administrator for all hosts in the environment.

You can also change the system administrator of a host by removing the existing system administrator and adding the new system administrator.
