VMware makes some pretty nice graphics for all their documentation/presentations.  If you ever wanted to use any of those graphics (like the one to the side of this post), VMware provides a number of these diagrams, icons, and stencils on their community website.  Theres three “packs” of Diagrams and Stencils currently out there:
2009 Pack
2010 Packs
Next time you need to do a presentation or some documentation kick it up a notch and use these diagrams. Â Those graphic artists at VMware do a great job making some fantastic stuff.
