Creating an Automated ESXi Installer

Back in the summer, I saw Stu’s Post about automating the installation of ESXi. I was reminded again by Duncan’s Post. Then, I found myself in a situation when a customer bought 160 blades for VMware ESXi. With this many systems, it would be almost impossible to do this without mistakes. I took the ideas from Stu and Duncan and created an ESXi automated installer that works from a PXE deployment server, like the Ultimate Deployment Appliance. I took it a step further and added the ability to use a USB stick or a CD for those times when PXE is not allowed. The document below is a result of it.

This is a little different than the idea of a stateless ESXi server, where the hypervisor actually boots from PXE. This is the installer booting from PXE so that the hypervisor can be installed on local disk, an internal USB stick or SD card. You could also use it for a “boot from SAN” situation, but extreme care should be taken so you don’t accidentally format a VMFS disk.

As always, if anyone has comments, corrections, etc., please feel free to post a comment below.
