This PDF has been a long time coming. It is a a document that lists just about every maximum value to do with VI3 possible. For example, how many iSCSI HBAs can you install on one ESX host? This document covers about 80% of the questions I receive on VMware a week, “How much/many of X does ESX/VirtualCenter support?” This document has the answers to your questions!
Kudos to the team at VMware that put this together!
