A Central Site is a Configuration Manager Primary Site that resides at the top of the Configuration Manager hierarchy. Purpose of using a central administration site is to configure hierarchy-wide settings and to monitor all sites and objects in the hierarchy. All Database information rolls from the child to the parent and is collected by the Central Site’s Configuration Manager Database. The Central Site can administer any site below it in the hierarchy and can send data down to those sites as well.
A central administration site is
suitable for large-scale deployments, provides a central point of
administration, and provides the flexibility to support devices that are
distributed across a global network infrastructure. Use this topology when you
require more than one primary site to support management of all your devices
and users. It's required when you need to use more than a single primary site.
- The central administration site supports only primary sites as child sites.
- It supports up to 25 primary sites that enable you to extend the scale of your hierarchy.
- When you use a central administration site, it's the only place where you see site data from all sites in your hierarchy.
- It coordinates site-to-site data replication, which includes the configuration of sites and clients throughout the hierarchy.
- The central administration site can't have clients assigned to it.
- The central administration site doesn't support site system roles that directly support clients, such as management points and distribution points.
