By virtualising compute we can benefit from a smaller datacentre footprint, less use of power and other hardware such as networking equipment, cost savings from server consolidation, better utilisation and management of existing resources, improved disaster recovery and availability. ESXi optimises the use of a physical servers resources to be logically shared out for virtual machines. VMware ESXi is a bare-metal hypervisor deployed as a stateful or stateless install. Finally, the Windows vCenter Server and external PSC deployment models are now depreciated and not available with vSphere 7.0.
