Better understanding Memory Management in vSphere 5.

Ran into a great KB article (2017642) today that diagrammed the process of memory management for vSphere 5.  We’ve all used ESXTOP and the vCenter console to check on Host and VM memory before but this concise diagram should help us better understand the information returned by those invaluable troubleshooting tools.  Check out the snippets below and the full diagram here.
Definitely worth checking out.
