Power Management Overview

Note: Power management (including Wake-on-LAN) is a separately licensable add-on to Shavlik Protect.

The power management function enables you to control the power state of the physical machines and the online virtual machines in your organization. The primary reasons for using power management are to:

You can shut down, restart, or wake up machines either immediately or on a scheduled basis. You also have the ability to put machines into a sleep or hibernate state.

Tip: If you want to perform power tasks on offline virtual machines that reside on an ESXi Hypervisor, you can do so using the Virtual Inventory feature.

Extremely Flexible Implementation Options

Shavlik Protect provides a number of ways for you to implement the power management options.

Scheduled shutdowns and restarts are typically used for reducing power or turning off machines at night, over weekends, or on holidays. This can be used to fulfill a corporate "green" initiative by saving power when machines are not being used. The machines must initially be in a fully powered on state in order for the scheduled job to be performed.

The Wake-on-LAN request can be issued immediately, or it can be scheduled to occur at a specific time. It's like scheduling a wake up call for each machine. For more information on WoL, see Wake-on-LAN Implementation Notes.

Note: Machines that are sleeping, hibernating, or powered off cannot be restarted or awakened using a power state template, they must be awakened using the WoL feature.

Agentless vs. Agent-based

Power management tasks can be performed using either an agentless or an agent-based method. This section describes the agentless method. For information on performing agent-based power tasks, see Creating and Configuring a Power Task.

Note: An agentless power state task will push a small number of files from the console to each target machine. If a large number of machines are involved it may affect the performance of your network.
