VMware ESXi 6.7 - Hardware not yet certified for upgrade

VMware ESXi 3.5 - 6.7 Hypervisor Size Comparison

The VMware bare-metal hypervisor ESXi is in the market for over 10 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 6.7.

  • 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

Using the first 3D Xpoint based Intel Optane SSD with ESXi

I could get my hands on Intel's first 3D XPoint based SSD to figure out how it performs.

3D XPoint is a new non-volatile memory technology that has been developed by Intel and Micron.

With 32GB, it doesn't make sense to buy them for anything else than their intended use case: Cache device to enhance SSD/HDD Performance. If you want to use Optane technology as VM Datastore, wait a couple of months when devices with a higher capacity are available.
