Thanks to boche.net for pointing this document out to me. This (Configuration Maximums for Virtual Infrastructure 3) is the official VMware document listing maximum values for ESX Host,clients, and VCenter.
My boss and I where just discussing how many host you could have connected to the same LUN, I was thinking 10-15, he was more around 6. Looking at this document its 32. We where way off.
I?m adding my first 3i boxes in 2 weeks, 64GB of ram each?yummy.
