Of particular note if you still have DOT7 systems:
The installer installs both System Manager 3.0 and System Manager 2.2.0.1. System Manager 3.0 enables you to manage clustered Data ONTAP systems and System Manager 2.2.0.1 enables you to manage 7-Mode systems. System Manager 2.2.0.1 supports all the features, enhancements, and changes in the System Manager 2.2 release.

System Manager 3.0 is launched in a new browser tab or window if you are managing clustered Data ONTAP systems. Similarly, System Manager 2.2.0.1 is launched in a new browser tab or window if you are managing 7-Mode systems.
