System Center 2012 R2 Configuration Manager Design

Before we install the System Center 2012 R2 Configuration Manager it would be better to have an idea on System Center 2012 R2 Configuration Manager Site and System Roles and how are we going to install the roles and their limits. In most of the cases planning for hardware and software requirements for Configuration manager takes more time, so it is very important to understand about the site and system role scalability.

  • Central Administration Site (CAS) – A central administration site can support up to 25 child primary sites. When you install a Central Administration Site and use an Enterprise or Datacenter edition of SQL Server, the hierarchy can support a combined total of up to 400,000 devices. So you must plan for CAS only when an organization has over 1,00,000 clients.
  • Primary Site – Each primary site can support up to 250 secondary sites and up to 1,00,000 clients.
  •  Secondary Site – A secondary site supports a maximum of 5,000 clients. For secondary sites SQL Server must be installed on the site server computer and in a location if there are fewer than 500 clients, consider a distribution point instead of a secondary site.
  •  Management Point – Each primary site supports up to 10 management points and each primary site management point can support up to 25,000 computer clients. Each secondary site supports a single management point which must be installed on the site server computer.
  • Distribution Point – With System Center 2012 R2 Configuration Manager each primary and secondary site supports up to 250 distribution points and each distribution point supports connections from up to 4,000 clients. Each primary site supports a combined total of up to 5,000 distribution points. This total includes all the distribution points at the primary site and all distribution points that belong to the primary site’s child secondary sites. Each primary and secondary site supports up to 2000 additional distribution points configured as pull-distribution points. For example, a single primary site supports 2250 distribution points when 2000 of those distribution points are configured as pull-distribution points.
  • Software Update Point – A software update point that is installed on the site server can support up to 25,000 clients.
  • Fallback status point – Each fallback status point can support up to 100,000 clients.
