VMware Auto Deploy is a feature introduced from vSphere 5.0 which allows rapid deployment and configuration of a large number of ESXi hosts without having the image installed on each and every server. This is the absolute fastest way to have a large vSphere Infrastructure up and running, in no time. Using Autodeploy, you can specify the image to deploy and the hosts to provision with the image. Optionally, you can specify host profiles to apply to the hosts, and a vCenter Server folder or cluster for each host. When a physical host set up for Auto Deploy is turned on, Auto Deploy uses a PXE boot infrastructure in conjunction with vSphere host profiles to provision and customize that host. Auto Deploy uses PXE to network boot servers and dynamically load and configure an ESXi image directly into the host's memory. When a server boots for the first time, the Auto Deploy server will identify the new server, assign an appropriate ESXi Image Profile and Host Profile, and place the server into the proper vCenter folder or cluster.
The following white paper talks about creation of Dell customized VMware ESXi offline image depot from VMware online ESXi depot. This paper also covers configuring stateless boot of the thus created Dell customized VMware ESXi offline image depot using VMware vSphere Auto Deploy software. This document is intended to give users a good understanding on setting up stateless boot using Dell customized VMware ESXi offline image depot right from scratch.
