VMware, Inc.1Configuration Maximums
VMware® vSphere 5.0When you select and configure your virtual and physical equipment, you must stay at or below the maximums supported by vSphere 5.0. The limits presented in the following tables represent tested, recommended limits, and they are fully supported by VMware.“Virtual Machine Maximums” on page1“ESXi Host Maximums” on page2“vCenter Server Maximums” on page6“vCenter Server Extensions” on page7The limits presented in this document can be affected by other factors, such as hardware dependencies. For more information about supported hardware, see the appropriate ESXi hardware compatibility guide. Consult individual solution limits to ensure that you do not exceed supported configurations for your environment.The Configuration Maximums for vSphere 5.0 covers ESXi and vCenter Server.Virtual Machine MaximumsTable1 contains configuration maximums related to virtual machines.Table1.
