R2 will include a number of new things. One of the really big news in Ops Mgr 2007 R2 is cross platform capabilities. In this demo Barry Shilmover uses Ops Man to manage an application that is spread across SQL Server, Oracle, MySQL, Apache, and IIS, hosted on Windows, Solaris, Suse, and Redhat. Other news are integrated service level reports and dashboard, better performance and a number of improvments in the console for example new monitoring templates.
The Operations Manager 2007 R2 Beta will be available for download end of November. You can read more about Ops Mgr R2 here.
