How to Install VMware ESXi with Smaller OS partition (VMFSL): systemMediaSize

In this short tutorial I am showing you the magic of systemMediaSize and what you can do with it.
Ok, it helps reducing the size of OS partition (VMFSL) from default size which varies according to the disk size.

Regarding the VMFSL partition, so far I got the following sizes, as I said it depends of the disk size:
128GB installation disk – VMFSL = 111.14 GB
256GB installation disk – VMFSL = 119.9 GB

The size for “min” mentioned in the ESXI articles is incorrect. It is not 33GB but 25GB.
There are two articles mentioning 33G:
https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.esxi.install.doc/GUID-474D003B-C6FB-465D-BC1B-5FD30F8E2209.html?hWord=N4IghgNiBcIM4E84BcCmBbAsqgJgSzAGU8AvVEAXyA#esxi-70-system-storage-links-2
https://kb.vmware.com/s/article/81166
But according to my tests so far, the min size is nowhere near 33GB.
