You probably are all familiar with the component posters that Microsoft put out for Several technologies. You have the Exchange 2010 (Exchange Server 2010 Architecture Poster), Windows 2008 R2 (Windows Server 2008 R2 Feature Components Poster) & Hyper-V (Hyper-V Component Architecture).
I have them hanging on the walls around our offices and these make a great tool to discuss the technology and where what is being done or accomplished. Or as a reference when you need to explain some features. I suggest you download them and have them plotted in a print shop.
Microsoft recently put out a new version of the Hyper-V Component Architecture poster with the Windows 2008 R2 Service Pack 1 features (Windows Server 2008 R2 Hyper-V Component Architecture (with Service Pack 1)). It’s nice to see that they update these so quickly. We’re plotting this on A0 as we speak.
