This document is a guide to vSphere resource management, which mainly introduces the resource management features and usage of ESX 4.0, ESXi 4.0, and vCenter Server 4.0.
The document introduces resource management in a vSphere environment, describing how CPU, memory, storage, network and power resources are allocated, reserved, and limited for virtual machines and resource pools. It explains access control, resource pools, and the role of clusters, Distributed Resource Scheduler (DRS) and Distributed Power Management (DPM).\n\nDetailed chapters cover managing CPU and memory resources, creating and using DRS clusters, NUMA considerations, performance monitoring utilities such as esxtop and resxtop, and advanced host and VM properties. The guide is intended for system administrators who need to understand and customize default resource behavior. This manual is written in Chinese.
| CPU share value – High | 2000 per virtual CPU |

| CPU share value – Normal | 1000 per virtual CPU |
| Memory share value – Normal | 10 per MB of VM memory |
Resource management is the process of allocating resources from providers to users, allowing dynamic redistribution to use capacity efficiently.
