Ubuntu Server Power Management Techniques
Ubuntu Server provides several techniques for managing power consumption. In this section, we will discuss some of the most common techniques.
Configuring the BIOS/UEFI Settings
The Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI) settings control various hardware aspects of the server, including power management settings. By accessing the BIOS settings, you can configure the server to optimize power usage, such as adjusting the processor clock speed, enabling sleep modes, and disabling unnecessary components. Consult your server documentation for specific instructions on how to access and configure the BIOS/UEFI settings.
Using Power Management Tools
Ubuntu Server provides various power management tools that allow you to monitor and control power usage. One of the most commonly used tools is PowerTOP, a command-line utility that displays power consumption statistics and suggestions for optimizing energy usage. You can install PowerTOP using the following command:
sudo apt-get install powertop
Monitoring Server Power Consumption
Monitoring server power consumption is a crucial step in managing power usage. By monitoring power consumption, you can detect anomalies, identify power-hungry components, and optimize power management. Ubuntu Server provides several tools for monitoring power consumption, such as the Linux PowerTOP tool and the Intel Data Center Manager (DCM) Software.
Configuring Sleep Mode
Sleep mode is a power-saving state that conserves energy by turning off system components, such as the monitor, hard drive, and processor. Ubuntu Server provides various sleep modes, such as Suspend to RAM, Suspend to Disk, and Hybrid Sleep. By configuring sleep mode, you can reduce energy consumption and improve server performance. To enable sleep mode, you can use the following command:
sudo systemctl suspend
Power Management Policies
Power management policies are sets of rules that dictate how the system manages power consumption. Ubuntu Server provides several power management policies, such as Performance, Balanced, and Power Saver. By configuring the appropriate power management policy, you can optimize energy usage for your specific needs.
Controlling Processor Frequency
The processor frequency directly affects the power consumption of the server. By controlling the processor frequency, you can optimize power usage. Ubuntu Server provides various tools for controlling processor frequency, such as the cpufrequtils package. To install cpufrequtils, use the following command:
sudo apt-get install cpufrequtils
