This post describes the NSX for vSphere Configuration Maximums for version 6.0.x, 6.1.x and 6.2.x.
Whenever I got into a discussions about sizing, scalability and maximums of NSX I always turned to an excellent post written by Martijn Smit. But this post only contained information until version 6.1.x and not the latest version 6.2.x. And then during one of my projects some questions around the scalability of version 6.2.x came up and we had to do some research to find these scalability numbers. You can find the results of that research below.
