VMware configuration maximums from 1.0 to 5.1

VMware has really grown in scalability from the early days of ESX 1.0 with each new release of vSphere. I put together this table on how the configuration maximums have increased over the years so you can see just how much it scales over the years. VMware has published there Configuration Maximums documentation with each release starting with VI3 which you should be familiar with especially if you are trying to get a certification. I pieced together the earlier versions from the installation documentation for each release, there isn’t much info available on ESX 1.0 so if you know anything please fill in the blanks for me. Notice how the VM virtual disk size of 2TB has never changed, this is to due file system limitations that VMware has not yet been able to overcome. With their new Virtual Volumes architecture that limit may finally be gone. Also note on the earlier versions the documentation did not state a 2TB virtual disk limit although I’m almost positive it existed, the documentation stated “9TB per virtual disk”, not sure why though.

In addition hears a diagram from VMware that depicts the configuration maximums in a slightly different manner:
