SCCM 2007 Site System Roles

SCCM Sites 

A site consists of a site server, site system roles, clients, and resources. A site always requires access to a Microsoft SQL Server database. There are several types of SCCM 2007 sites. A SCCM 2007 site uses boundaries to determine the clients belonging to the site. Multiple sites can be configured into site hierarchies and connected such that you can manage bandwidth utilization between sites. A SCCM 2007 site is identified by the three-character code and the friendly site name configured during Setup and types of sites as follows.

Primary Sites-A primary site stores SCCM 2007 data for itself and all the sites beneath it in a SQL Server database.

Secondary Site-A secondary site has no SCCM 2007 site database. It is attached to and reports to a primary site. The secondary site is managed by a SCCM 2007 administrator running a Configuration Manager 2007 console that is connected to the primary site. The secondary site forwards the information it gathers from Configuration Manager 2007 clients, such as computer inventory data and Configuration Manager 2007 system status information, to its parent site. The primary site then stores the data of both the primary and secondary sites in the SCCM 2007 site database. The advantages of using secondary sites are that they require no additional SCCM 2007 server license and do not require the overhead of maintaining an additional database. Secondary sites are managed from the primary site it is connected to, so they are frequently used in sites with no local administrator present. The disadvantage of secondary sites is that they must be attached to a primary site and cannot be moved to a different primary site without deleting and recreating the site. Also, secondary sites cannot have sites beneath them in the hierarchy.

Central Site -A central site has no parent site. Typically, a central site has child and grandchild sites and aggregates all of their client information to provide centralized management and reporting. A site with no parent and no child site is still called a central site although it is also referred to as a standalone site. A central site to collect all of the site information for centralized management.

Parent Site-A parent site is a primary site that has one or more sites attached to it in the hierarchy. Only a primary site can have child sites. A secondary site is always a child site. A parent site contains pertinent information about its lower level sites, such as computer inventory data and SCCM 2007 system status information, and can control many operations at the child sites.

Child Sites-A child site is a site that is attached to a site above it in the hierarchy. The site it reports to is its parent site. A child site can have only one parent site. SCCM 2007 copies all the data that is collected at a child site to its parent site. A child site is either a primary site or a secondary site.

Site Systems 

Each site contains one site server and one or more site systems. The site server is the computer where you install SCCM 2007 and it hosts services required for SCCM 2007. A site system is any computer running a supported version of Windows® or a shared folder that hosts one or more site system roles. A site system role is a function required to use SCCM 2007 or to use a feature of SCCM 2007. Multiple site roles can be combined on a single site system, including running all site roles on the site server, but this is usually appropriate only for very small and simple environments.

Site System Roles

  • Management Point– The site system role that serves as the primary point of contact between SCCM 2007 clients and the Configuration Manager 2007 site server.
  • Server locator Point-A site system role that locates management points for SCCM 2007 clients.
  • Distribution Point-A site system role that stores packages for clients to install.
  • Software Update Point-A site system role assigned to a computer running Microsoft Windows Server Update Services (WSUS).
  • Reporting Point-A site system role hosts the Report Viewer component for Web-based reporting functionality.
  • Fallback Status Point– A site system role that gathers state messages from clients that cannot install properly, cannot assign to a Configuration Manager 2007 site, or cannot communicate securely with their assigned management point.
  • PXE Service Point-A site system role that has been configured to respond to and initiate operating system deployments from computers whose network interface card is configured to allow PXE boot requests.
  • User State Migration Point-A site system role that stores user state data while a computer is being migrated to a new operating system.
