VMware vSphere Comparisons 5.5 vs 6.0 vs 6.5 vs 6.7 at one place

Or, What all are the major capacity supporting changes or enhancements across VMware vSphere 5.5, 6.0, 6.5, and 6.7.
Or, Major maximums differences of VMware vSphere 5.5, 6.0, 6.5, and 6.7

Descriptions: As the new release 6.7 of VMware vSphere is out in the market, it’s important for you to check out what all are the major capacity support enhancements or changes are done in this release before you think of upgrading your current ESXi Infra to any of the next releases.

In this article, I will take through some major difference within vSphere version 5.5, 6.0, 6.5, and 6.7. This article is focused on checking out capacity enhancement/maximums and not covering other enhancements and features which may be ESXi OS level, Graphics or etc... I tried consolidating some data points from all datasheets of vSphere Maximums which really effects each level of VM Infra.

Here are the comparisons

There may be some further maximum and minimum supported capacity of ESXi hosts and other VMware components. To know more in-depth and explore all possible segregation of supported capacity limits, please refer the below VMware KB:

Added vSphere 6.7 in the list of comparison.

Cheers, please write me back if you have any query or feedback on this…


  1. Correction, ESXi 6.0 host now supports support up to 480 physical CPUs and 12 TB RAM (which was 320 CPUs and 4 TB in vSphere 5.5)

    1. Thanks for your input.. really appreciate it..

      "12 TB is supported on specific OEM certified platform. See VMware Hardware Compatibility Limits for guidance on the platforms that support vSphere 6.0
      with 12 TB of physical memory"
