This video demonstrates the power of PXE booting, and automating Operating System installation with Red Hat Kickstart and similar technologies.
The raw footage is 13 minutes. Which is actually quite fast, but is rather boring to watch.
The video has been edited to demonstrate the little amount of interaction required to meet Oracle pre-requisites, when these pre-installation requirements have been automated.
The stuff that has been edited for time, follows.
1) The long boot process: system scanning SCSI bus and RAID controllers; basic self tests on hardware.
2) Startup of the RedHat installation: it takes a few minutes for all of the disk and hardware drivers to load.
3) Data partition formatting: the largest volume took well over a minute to complete formatting.
