Sizing SCCM Architecture for Deployment Features

Site System	Maximum recommended number per site
Clients	Up to 200,000 per hierarchy
Primary Site Server	Up to 100,000 directly assigned clients
Secondary Site Server	Up to 500 secondary sites per primary Note The number of secondary sites recommended per primary site is based on reasonably well connected and reliable WAN network connections. Unreliable server hardware or network connections can dramatically reduce this number.
Management Point	Up to 25,000 clients Note To support more than 25,000 clients in one site, management point site systems can be configured to use Network Load Balancing (NLB).
Distribution Point	Up to 4,000 clients Note The number of clients that one distribution point can support is dependent on network speed, disk performance, and software distribution package size.
Branch distribution point	Up to 2,000 per site, each capable of supporting up to 100 clients.
Software update point	Up to 25,000 clients Note To support more than 25,000 clients in one site, software update point site systems can be configured to use Network Load Balancing (NLB).
System Health Validator point	Up to 100,000 clients (or one per hierarchy if less than 100,000 clients)
Fallback status point	Up to 100,000 clients (or one per site)
