Minimum Operating System Requirements
The VCM for Virtualization Agent Proxy machine must be running Windows Server 2008 R2 or Windows
Server 2003 SP2. For more information to install and configure the Agent Proxy, see "Install and Configure
a Windows Server 2008 R2 Operating System" on page 16.
Minimum Hardware Requirements
The VCM for Virtualization Agent Proxy is installed on the Collector by default. Although the

managed, additional Agent Proxy servers must be configured to maintain the ratio of one agent proxy for
each 50 ESX servers.
The designated VCM for Agent Proxy servers should meet the following minimum requirements for
physical hardware or virtual machines. An Agent Proxy server meeting these requirements can manage
approximately 50 ESX Servers.
