Hi Izattafact,
dashboard parts are independent beasties and don't talk to eachother they way you're describing (that I've seen anyway), at least not without some kind of add-on.
The only native way I can think of to achieve something approaching what you're after is to create yourself distributed applications, or even just performance views, each representing one of your "servers".
With the distributed apps, you can look at them / create views for them and alert on them independently, also setting yourself up a view of multiple distributed applications to get your "single picture of the world" scenario in place. This would give you you something along the lines of a traffic light view that you could open using the web console (with a url targetting a particular view you've created).
The unfortunate thing is that there is very little out there on how to go about creating good distributed applications and the two videos that used to be up on the MS site now seem to have been moved somewhere you can't get at them anymore (gotta love site redesigns!).
These aren't quite what you're after but you may be able to shape parts of them into something to meet your needs:
http://technet.microsoft.com/en-us/library/cc540485.aspx for the Service Level Dashboard for SCOM 2007
the Visio 2010 for SCOM 2007 R2 add-in looks like it would be a nice visual way to monitor distributed apps amongst other things http://visiotoolbox.com/downloads/addins/Visio_2010_Add-in_for_System_Center_Operations_Manager_2007_R2_961.aspx in pretty dynamic views you can publish to sharepoint
There's also a company called savision that do a mapping product that sits on top of Opsmgr and gives you live "maps" of your environment but I'm thinking it sounds pretty close to what the visio add-on does http://www.savision.com/solution
I'm sorry but that's about the extent of the assistance I can give you with this, other Experts may be able to add more suggestions.
Good Luck!
