In System Center 2012 Configuration Manager SP1 Beta you now have the exiting option to have multiple SUP roles connected to a site server. To see how that works I started testing this. My starting point is 1 primary site server S01 installed on server 2012 OS with CM version 2012 SP1 Beta and my endpoint should be 1 primary site server with 2 remote SUP’s. The 2 remote servers I have installed with server 2012 OS and I enabled WSUS, but did not configure WSUS since we want to have CM 2012 handle this. Having all servers prepared I jump into the CM 2012 console to add the first SUP to the S01 primary site server. In the Administration node I click on Sites and choose Create Site System Server in the ribbon, see pictures below


The wizard is started

I will not put all the screenshots in this blog, I presume you can go through all steps by yourselve, but I will add screenshots that are interesting in my opinion. The next picture shows the step where you have to choose the synchronization source and given that this is the first SUP in the hierarchy I choose the option: Synchronize from Microsoft Update.

After this I quickly go through the steps, close the wizard and check the sitecomp.log to follow the installation and check installation is successful. When the installation is ready I start a synchronization from the console. In the wsyncmgr.log you can follow the synchronization and when this sync has finished, updates should be visible in the console. When I check the console I see this is the case and I can start with step 2 and install a second SUP, so again I start the Create Site System Wizard. Below you can see the steps for adding SUP two.

What you maybe have spotted here is that there has not been a question about sync source, sync schedule, classification or products. Perhaps not strange, because these questions you had to answer with the installation of the first SUP. When SUP two has been installed I start a synchronization of the updates again to see what happens and if I can see how the second SUP is treated. I open the wsyncmgr.log and check what happens, see picture below

For clarity I marked the interesting  bits in yellow and you can see SUP two is a replica of SUP 1. First the sync is started on the SUP that I installed first and when the sync is ready the replica, the SUP installed as second, is synchronized. Obviously the first installed SUP is the primary and al next SUP’s will be replica’s. So what happens if I remove the primary SUP? To see what happens I press delete on SUP 1 in the console and the following message pops-up, see picture below.

As you can see you get the possibility to select a new sync source for the site, since the software update point I want to delete is the sync source for all SUP’s.

My conclusion is that the possibility to install multiple SUP’s to a site server is a big step forward for Configuration Manager and that this is a nice solution for security and redundancy options. The next question however that I have is what happens if  the first installed SUP has a hardware failure and is not available? …That is something for a next blog.
