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
  • Performance considerations

At VMware, we value inclusion. To foster this principle within our customer, partner, and internal community, we have updated this guide to remove instances of non-inclusive language.

Intended Audience

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.
