Software updates-Software update points

This article mainly discusses the related concepts and contents of ConfigMgr software update points.

Comparison between WSUS and SUP Architecture the traditional software update under the Windows platform is the responsibility of WSUS under the SCCM system, and the software update of the CCM client is responsible for the SUP (software update point). In essence, SUP can be understood as encapsulating part of the WSUS function.

Service component function comparison function item WSUSSUP metadata synchronization WSUS service WSUS service (scheduled by SUP) update content package download WSUS service SCCM site server metadata storage WSUS database WSUS database and SCCM site database (obtained synchronously with WSUS database) update package data store WSUS update content folder site server content library (Content Library) client information WSUS database SCCM site database client Side update scan WSUS service SUP service client update get WSUS service management point client update download WSUS service distribution point client update status WSUS database SCCM site database

It can be seen that under the SCCM system, the update distribution mechanism reuses the services provided by the site server, management point and distribution point itself.

Pay attention to the software update.

If a subsite client at the SCCM level needs to use the software update feature,

At the top level of the SCCM level (CAS or stand-alone site) there must be a software update point role at the client site there must be a software update point downstream of the software update point will synchronize the update metadata service redundancy from the upstream software update point multiple software update points under the same site can provide redundancy functionality in SCCM 1702 and later, the software update point supports the fallback feature of the boundary group (fallback) in and after SCCM 1706 The fallback time of the software update point can be customized (default is 120min). For the client, each time they obtain the software update point service, they will use the most recently successfully contacted software update point as the preferred target client WSUS group policy conflicts with SCCM SUP. Do not configure WSUS related policies in the client's group policy. Instead, the SCCM policy should dynamically acquire the client to discover and install the applicable update client through WUA (Windows Update Agent) to obtain the approved update through the management point, and to report the update installation client to download the update content through the distribution point.

It is the original intention of this series of articles to refine the basic knowledge, precautions, operating mechanism and troubleshooting methods involved in SCCM for readers. There are already many articles in the network to refer to the information on the various components and functional deployment steps of SCCM, so this series of articles do not focus on providing deployment guides similar to Step-by-Step, please forgive me. At the same time, due to the limitations of personal ability and knowledge, there are inevitably some mistakes and mistakes in the article. I hope you can correct them. Thank you very much.
