With the release of VMware vSphere 4.1, 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. The innovative VMware ESXi architecture operates independently from any general-purpose operating system (OS), offering improved security, increased reliability and simplified management.
