vSphere Resource Management describes resource management for VMware® ESXi and vCenter® Server environments.
This documentation focuses on the following topics.
Resource allocation and resource management concepts
Virtual machine attributes and admission control
Resource pools and how to manage them
Clusters, vSphere® Distributed Resource Scheduler (DRS), vSphere Distributed Power Management (DPM), and how to work with them
Datastore clusters, Storage DRS, Storage I/O Control, and how to work with them
Advanced resource management options
This information is for system administrators who want to understand how the system manages resources and how they can customize the default behavior. It’s also essential for anyone who wants to understand and use resource pools, clusters, DRS, datastore clusters, Storage DRS, Storage I/O Control, or vSphere DPM.
This documentation assumes you have a working knowledge of VMware ESXi and of vCenter Server.
Task instructions in this guide are based on the vSphere Web Client. You can also perform most of the tasks in this guide by using the new vSphere Client. The new vSphere Client user interface terminology, topology, and workflow are closely aligned with the same aspects and elements of the vSphere Web Client user interface. You can apply the vSphere Web Client instructions to the new vSphere Client unless otherwise instructed.
Not all functionality in the vSphere Web Client has been implemented for the vSphere Client in the vSphere 6.5 release. For an up-to-date list of unsupported functionality, see Functionality Updates for the vSphere Client Guide at http://www.vmware.com/info?id=1413.
