VMware vFabric Data Director consists of the database lifecycle management platform and vFabric Postgres (vPostgres).

The Data Director hierarchy has the following levels.

System (the database lifecycle management platform)


Database groups

Databases (vPostgres databases)

System administrators perform management tasks at the system level, which is the top level of the hierarchy. To edit system-level settings you must have system privileges, but having system privileges does not allow you to make changes to the other levels.

A system can contain multiple organizations. An organization can contain multiple database groups. A database group can contain multiple databases. You cannot create database groups at the system level. They can exist only within organizations. Databases can exist only within database groups.

The following figure shows the Data Director system hierarchy.

Data Director System Hierarchy
The system level is at the top of the data director hierarchy. Below the system level are two organizations. One of the organization has two database groups, and one database group has two databases below it in the hierarchy.

System administrators manage Data Director resources at the system, organization, and database group levels. System administrators create resource bundles from vSphere resource pools (CPU and memory resources) and networking and storage resources, and allocate one or more resource bundles to each organization. Organization administrators assign resources from their resource bundles to database groups for consumption by databases.
