4.7. Data Centers and Permissions

4.7.1. Managing System Permissions for a Data Center

As the SuperUser, the system administrator manages all aspects of the Administration Portal. More specific administrative roles can be assigned to other users. These restricted administrator roles are useful for granting a user administrative privileges that limit them to a specific resource. For example, a DataCenterAdmin role has administrator privileges only for the assigned data center with the exception of the storage for that data center, and a ClusterAdmin has administrator privileges only for the assigned cluster.
A data center administrator is a system administration role for a specific data center only. This is useful in virtualization environments with multiple data centers where each data center requires an administrator. The DataCenterAdmin role is a hierarchical model; a user assigned the data center administrator role for a data center can manage all objects in the data center with the exception of storage for that data center. Use the Configure button in the header bar to assign a data center administrator for all data centers in the environment.
The data center administrator role permits the following actions:
  • Create and remove clusters associated with the data center.
  • Add and remove hosts, virtual machines, and pools associated with the data center.
  • Edit user permissions for virtual machines associated with the data center.

Note

You can only assign roles and permissions to existing users.
You can change the system administrator of a data center by removing the existing system administrator and adding the new system administrator.
