During my project I tried to find out which System Center 2012 SP1 products support SQL Server 2012 AlwaysOn functionality . I took me quite some time after browsing all products for supported configuration I finally found following technet article http://technet.microsoft.com/en-us/library/jj628198.aspx which provides exactly the information I was looking for.
In System Center 2012 SP1, SQL Server 2012 AlwaysOn is supported in the following components:
SQL Server AlwaysOn is not supported with Data Protection Manager (DPM) and Configuration Manager.
A Word document describing SQL Server 2012 AlwaysOn can be found at SQL Server 2012 AlwaysOn: Multisite Failover Cluster Instance.
Hope this helps saving some time
