Thanks for pointing me in the right direction. After I made my initial post I went on a hunt, this time taking more time to read what each of those files was about. I also read about how to manage your system and came to the same result that you provided. In my case since I'm using SBS 2011 which is based on Windows Server 2008 R2 which is a 64 bit OS, I used the OpenManager Server Administrator (Managed Node) 64 bit version.
After installing, I also installed the Dell iDRAC Service Module so I could link the server into the iDrac controller.
I'm now moving on to setting up the alerts and doing some hardware fail testing.
Is there anything else I should be looking at installing?
Thanks for the replies.
