This module describes the basic concept of virtualization, introduces VMware ESXi and the virtual machine.

3、 This module then shows you the fundamental components of vSphere and how vSphere can be used in your datacenter.Module LessonsLesson 1:Introduction to VirtualizationLesson 2:VMware vSphere User InterfacesLesson 3:Overview of ESXiLesson 1:Introduction to VirtualizationLearner ObjectivesAfter this le
