VMware vSphere 6 is a virtualization platform that lets users consolidate and optimize their IT environments by running many virtual machines (VMs) on a single physical desktop or server.

VMware vSphere 6 contains technologies such as Content-Based Read Cache (CBRC) for faster storage I/O, Resource Management Enhancements, and Distributed Resource Scheduler (DRS) for intelligent distribution of CPU and memory resources across virtual machines.
