VMware vSphere 6.x

We often receive questions regarding the differences between the Free and Paid version of VMware vSphere 6.x. We hope this article will help you to discover the differences between both versions of VMware vSphere 6.x.

At Snel.com we offer the free version of VMware vSphere 6.x (which is called VMware Hypervisor) because the Free version is identical to the paid VMware vSphere 6.x version. This means that you will get the exact same ISO image at free charge. However, the Free VMware vSphere 6.x version only stays unlocked for 60 days.

So the Hypervisor works as a full version for 2 months. When the trial period ends some features will be disabled. In order to use the full version again, you need to enter a serial number but before you upgrade to the paid VMware vSphere 6.x version you should consider whether the upgrade really is necessary. Below the limitations of the Free version have been highlighted.

What are the VMware Hypervisor (Free) limitations?

The main difference between the free version and paid version of VMware server are the below restrictions:

  • You are not able to manage via vCenter Server
  • Only 1 physical server is allowed (cluster with more physical servers not allowed)
  • Only 2 physical CPU per Hypervisor is allowed
  • Only 128 vCPU per Hypervisor is allowed
  • Maximum amount of vCPUs you can assign to a VM is limited to 8
  • Physical RAM limit of 12TB per Hypervisor is allowed
  • You need to acquire VM support

If you would like to upgrade to the paid version, then the only thing different between the free and the paid versions are the license keys. The software contains all of the functions, but you need to enable it with the keys. You do not have to install anything other than the new key and you need to configure the new functions.

  1. Any idea about updates for the free version?
    If there is a new version out, can I run the new ISO and choose update?
    And do I have to require a new free license each time I update (assuming that it's possible)?
