VMware ESXi 3.5 - 6.0 Hypervisor Size Comparison

The first public release of VMwares bare-metal hypervisor ESXi was about 7 years ago. During that time we had lots of new features, including the latest outstanding introduction in vSphere 6.0 - Virtual Volumes. This post takes a look at how the hypervisor footprint has changed since ESXi 3.5.

  • 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

How did I determine the Hypervisor Size?
According to VMware documentation the footprint of ESXi 5 was 144MB and 150MB in ESXi 6. I could not reconstruct that completely so I compared the following packages:

  • The "image" package in ESXi 3.5
  • The "firmware" package in ESXi 4.x
  • The "esx-base" vib package in ESXi 5.x and 6.x

Within a major release, the size does not change much. This is a full table since vSphere 4.0:
