I was lucky enough to get a hardcopy version from the nice folks at the VMworld Labs in San Francisco a few weeks ago.
Also, very handy to have a PDF version to carry around on the iPad.
The poster is a reference to all things related to vSphere Standard Switch (VSS), vSphere Distributed Switch (VDS), and Virtual Extensible Local Area Network (VXLAN) technology. It provides you information on the different components, terminologies and parameters of VSS, VDS, and VXLAN. It also explains the advanced features of VDS and discusses some best practices.
