VMware ESXi 3.5 - 6.5 Hypervisor Size Comparison

VMwares bare-metal hypervisor ESXi is in the market for almost 9 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.

  • ESXi 3.5 - 46,01 MB

VMware ESXi 6.5 - Hardware not yet certified for upgrade

vmware-hcl-65Double check your vendor support when updating ESXi hosts from VMware vSphere 6.0 to 6.5. Some systems have not been certified by their vendor yet. The following servers were supported in vSphere 6.0 but are according to VMwares HCL not yet supported in vSphere 6.5.

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 only includes common vendors: Apple, HP, Cisco, DELL, Fujitsu, Hitachi, IBM, Lenovo and Nutanix.
  • The list has been created with the help of my HCL in JSON Format.
  • Follow the comments to get notified about updates.

ESXi Version Information now available as JSON (incl. Script example)

Out of many reasons, I need VMware ESXi version information in a format that can be reused in scripts. I maintain a manual list since a couple of years but this list can't be used for automation purposes. VMware does not provide this information in the required format, so I created my own database which is now also available as JSON file.

Backup Solutions for Free ESXi

VMware offers a free version of their vSphere Hypervisor with some limitations like the lack of vCenter support. Another limitation is that APIs are read-only, so it's not possible to use the Data Protection API aka. VADP to make Backups.

Creating backups of Virtual Machines is also important on standalone ESXi hosts. The API limitation makes it impossible to create incremental CBT aided backups, but it's not impossible to create full copies of virtual machines. The post explains the technique to create backups and takes a look at solution that use these techniques.
