Came across this great article on setting up a scripted installation of vSphere 4.1.
Here is a quote from the article…
"Scripted installation is a new feature for ESXi which is introduced with the release of vSphere 4.1. In this article I’m describing the setup of my home lab in which I use this new feature. Please be advised that this article assumes some basic understanding of Windows and ESX and gives you some guidelines which you can alter for your own specific needs."
I highly recommend reading this guide if you are interested in scripting / automating you vSphere installations.
