From SCCM 2012 SP1 it is possible to add additional SUPs, ie. as failover.
I have a Standalone Primary Site server with co-existing sql server - all 2012 versions.
On the PS server I have installed almost all SCCM roles.
I now want to have failover SUP, installed on one of my DPs.
This is how I did it:
First, make sure that the SUP on the PS is working.
On the DP, add the "Windows Server Update Services" role.
As options, select "WID Database" and "WSUS Services".
When installation has finished, go to the SCCM console, and select "Add Site System Roles" for the DP.
Select "Software update point".
Configure WSUS for ports 8530 and 8531
Then just wait....
and suudenly, in Monitoring > Software Update Synchronization Status,
you will find your additional SUP listed, with the PS as Synchronization Source and Synchronization Status = Completed with Last Synchronization Error Code = 0X00000000
