SCCM 2007 - Staging WSUS updates

Posted on 2012-09-12

I have to come up with the best practise method of installing WSUS updates via SCCM.

So far I have set up Deployment templates for Office, Windows 7, and other software packages.

However, I am a bit confused by the way SCCM installs updates - it seems the deadline set in the SUP basically sets the start time for the updates to be installed. Maybe I am missing something, but doesn't this mean that all clients are going to be connecting to the server at once to pull the updates down?

Is there any way to get it to run like regular WSUS where the updates are slowly deployed out one by one in the background? I typically set a month deadline and by the time the month is up most of the updates have been installed.

    All SCCM download clients can use BITS and should preferably be configured for the same.

    Download and installation times are different (Provided you allow decent margin, with 9 odd patches a month, the load is not that much).

    Clients will not download it all at once.

    Thanks for the reply. So far I have just tested it with a my computer and a couple of other machines. The  updates all seem to start installing straight away as soon as the maintainance windows on the collection allows on  (past the deadline). This is on all computers.

    How can I set it up so that the installation times are different?

    Well they are all installed from the local computer so there is no load on the network.

    If you allow a decent margin then the SUP package will get downloaded in advanced using BITS. There should not be any cause to worry.

    If you are still concerned with your network load regarding Windows Updates/SCCM/WSUS

    With regards to a "decent margin" - can you be more specific?

    On the test machines I advertised the updates and set the deadline for 3 weeks in the future but they didn't start installing until the deadline passed.

    Does the SUP client download the updates in the background just like normal WSUS (I know it overlays WSUS) and just cache them until they are ready to be installed?
