VMware usually publishes a Configuration Maximums paper on their products. NSX has quite a bit of specifics that have a limit, but there is not an official configuration maximums paper yet. I hope there will be one soon, but for now I’ve compiled a list of findings from my travels on the interweb.

Most of the figures on NSX 6.1 are confirmed by a paper from PSO, others are from the documentation and real life limits.
