VMware ESXi 7.0 - Hardware not yet certified for upgrade

Double-check your vendor support when updating ESXi hosts to vSphere 7.0. Some systems have not been certified by their vendor yet. The following servers were supported in vSphere 6.7 but are according to VMware's HCL not yet supported in vSphere 7.0.

Your server is listed and you want to upgrade?

  • Usually, the list gets smaller a couple of weeks after a new vSphere version has been released. I will update this post when I notice changes.
  • Not supported does not say that it does not work.
  • Servers get certified by their vendor, not VMware. If you want a server to get certified, ask your vendor.
  • Vendor support matrices sometimes differ from VMware HCL. Please ask your vendor or VMware whether you are allowed to upgrade.
  • The list has been created with the help of my HCL in JSON Format.
  • Follow the comments to get notified of updates.
  • Did I miss something? Please comment.
  • The list only contains systems by the following vendors: Cisco, DELL, Fujitsu, Hewlett Packard Enterprise, Hitachi, IBM, Lenovo, and Supermicro

Demystifying vCenter Version and Build Number Mismatches

Have you ever wondered that the VMware vCenter Server build number mentioned in Release Notes does not match with the build number displayed in the vSphere Client? There are many different versions and build numbers used through the product. How the numbering works is different from Releases to Release. Here is an example of version numbers used in vSphere 6.7:

  • vCenter Server 6.7 U3f
  • Appliance Version: 6.7.0.43000
  • Windows Application Version: 6.7.0.31288
  • ISO/Installer/Update Build: 15976714
  • Appliance Build Number: 15976728
  • Windows Build Number: 15976721

In this article, I am going to explain where these numbers are used and also how the numbering differs from vSphere Release to vSphere Release (eg. vSphere 6.7 numbering standards differ from vSphere 6.5).

VMware ESXi 3.5 - 7.0 Hypervisor Size Comparison

The VMware bare-metal hypervisor ESXi is in the market for over 12 years now. During that time it has been continuously refined and added with new features. Since vSphere 5.0, the hypervisor size is very constant and has not increased severely. In this post, I am going to have a look at how much the hypervisor footprint has been changed from ESXi 3.5 to ESXi 7.0.ESX.

  • ESXi 3.5 - 46,01 MB
  • ESXi 4.0 - 59,99 MB
  • ESXi 4.1 - 85,19 MB
  • ESXi 5.0 - 132,75 MB
  • ESXi 5.1 - 125,85 MB
  • ESXi 5.5 - 151,98 MB
  • ESXi 6.0 - 154,90 MB
  • ESXi 6.5 - 135,39 MB
  • ESXi 6.7 - 129,51 MB

VMware Products without vSphere 7.0 Support at GA Day

VMware vSphere 7 has been released a couple of days ago. Before you jump in and upgrade your Production or Test environment, make sure that the software you are using on top of vCenter/ESXi is supported. To check if a product version is supported, refer to VMware Interoperability Matrix.

When checking the Interop Matrix, make sure that there is both, a minimum and a maximum version that is supported. For example, ESXi 6.0 support has been dropped in vSphere 7 which means that all ESXi Hosts need to be upgraded to at least ESXi 6.5.

I'm going to monitor the progress regularly and keep an updated list on my vSphere 7.0 landing page, so make sure to bookmark the following link: vSphere 7.0 Landing Page Read more »
