The vSphere Administration with the vSphere Client documentation provides information on managing a single ESXi host or vCenter Server system through a direct connection from the vSphere Client. You can use these tasks to manage hosts that are not connected to a vCenter Server system, or to troubleshoot or manage hosts that have become disconnected from the vCenter Server system that managed them.
This documentation is intended primarily as a reference for tasks that you can perform when you connect directly to a host or vCenter Server with the vSphere Client. For detailed information about vSphere networking, storage, security, virtual machine management, and other topics, see the appropriate vSphere documentation.
This information is intended for anyone who wants to manage a single ESXi host or vCenter Server system by connecting directly with the vSphere Client. The information is written for experienced Windows system administrators who are familiar with virtual machine technology and datacenter operations.
