If you were sitting there staring at your ESX 3.5/4.0 infrastructure and wondering, “How am I ever going to migrate to ESXi 4.1?” Well look no further as I have the link just for you.
VMware ESXi is VMware’s next generation hypervisor architecture and is designed to improve hypervisor management in the areas of security, deployment and configuration, and ongoing administration. In the vSphere 4.1 release VMware has added significant enhancements to either ESXi or the core tools that are used to manage ESXi. This paper describes the architecture of ESXi and then explains how various management tasks are performed in ESXi 4.1. This information can be used to help plan a migration to the ESXi architecture from the legacy ESX framework.
Below is an insert from the PDF Guide.
With the release of VMware vSphere™ 4.1 (“vSphere”), VMware announced plans to transition away from its classic VMware® ESX® hypervisor architecture, based on a Console Operating System (COS), in favor of its newer lightweight hypervisor architecture, referred to as VMware ESXi™. While functionally equivalent, the VMware ESXi architecture is significantly different from its VMware ESX predecessor (Figure 1). The innovative VMware ESXi architecture operates independently from any general-purpose operating system (OS), offering improved security, increased reliability and simplified management.
