Virtualization: VSphere 4
VMware's vSphere 4, in addition to the traditional server virtualization functionality of the VMware ESX and ESXi and VMware Infrastructure 3 on which it is built, is aimed at aggregating and managing processors, storage and networking as part of a dynamic operating environment. Its goal: to eliminate the cost and complexity that many enterprises might see while deploying a virtualization solution. New with vSphere 4 is VMware vStorage Thin Provisioning, which allows customers to overprovision the storage capacity of virtual machines while not actually tying physical storage capacity to a particular machine. Also new is VMware Distributed Power Management, a technology that uses VMware's VMotion function for automatic migration of virtual servers between physical servers.
