Primary Site

The primary site serves clients in well-connected networks. A primary site can have a CAS as its parent tier. A primary site cannot have another primary site as its parent tier. Since role-based administration is a real feature, no separate primary sites are needed for security, administrative, or data-segmentation purposes.

Extra primary sites can be added for the following reasons:
◆ Managing clients directly
◆ Providing a local point for administration
◆ Supporting more than 100,000 clients

The following are design rules for primary sites:
◆ Primary sites can be stand-alone or members of a hierarchy.
◆ A primary site cannot change its parent site relationship after the installation.
◆ A stand-alone primary site cannot be assigned to a Central Administration Site after the installation, but you can install an empty CAS above the stand-alone primary site.
◆ Primary sites that are installed as children of a CAS will configure database replication to the parent site automatically.
◆ Primary sites use database replication for the communication to their child and parent sites.
◆ Primary sites can have only a central administration point as a parent site.
◆ Primary sites can support one or more secondary sites as child sites.
◆ Primary sites process all client data from their assigned Configuration Manager clients.

◆ A primary site can support up to 10 management points for load balancing.
◆ A primary site can support up to 250 secondary sites.

The following site roles can be configured for primary site servers:
◆ Management point

◆ Software update point
