I am currently in the process of building lab environment to test VMware NSX network virtualization platform. If you are new to NSX or Network Virtualization in general, check out Ivan Pepelnjak’s awesome series on NSX. Definitely check out his other blog posts as well – this is my favorite networking related blog by far.
Making network diagrams is a tedious process. There are many automated diagraming tools, however, those are all for existing networks. For any fellow networking/virtualization professionals that may be tasked with building a NSX lab, here
is a fairly complete NSX infrastructure diagram that you can use as a starting point (see screenshot below). Simply modify the number of ESXi hosts, IP addresses, and other relevant components for your specific lab scenario.
