Configuration Manager - Central Administration Site

The central administration site coordinates inter-site data replication across the hierarchy by using Configuration Manager database. The central administration site also allows the administration of client agents, discovery performance, and software updates.

Important notes of central administration site:

1. Only one central administration site per hierarchy can be installed.
2. In configuring a Configuration Manager hierarchy, the central administration site is the first one must installed.
3. The central administration site cannot be joined or moved to an existing hierarchy.

Important considerations when deploying a central administration site:

1. It supports up to 25 child primary sites simultaneously
2. It participates in SQL database replication
3. It does not support client data and client assignment
4. It does not support a management point so no client can report to this site
5. Not all site system roles are available. It supports roles of Asset Intelligence Synchronization Point, Reporting Service Point and Software Update Point.
6. It used for all administration and reporting for the site hierarchy

Considerations when installing a central administration site:

1. When more than one primary site is present in a hierarchy
2. When there is a need to scale-up the number of clients that can be managed
3. When there is a need to off-load reporting and administration from your primary site
4. When there is a need to monitor and report from all sites and objects in the hierarchy
