What Is a Server Power Distribution Unit?

Definition and Role

A server power distribution unit is a device designed to distribute alternating current (AC) electrical power from a single source to multiple devices within data centers. Industry organizations define a server power distribution unit as a robust and reliable power strip made for server environments. It supports servers, routers, and switches by delivering efficient power distribution across the server rack. Unlike ordinary power strips, a power distribution unit offers features tailored for high-capacity and mission-critical settings. These units come in several types. Basic PDUs distribute power without monitoring. Intelligent PDUs provide real-time power monitoring, remote access, and control. Many PDUs include redundancy features, such as dual power inputs or automatic transfer switches, to ensure continuous operation. Data centers install a server power distribution unit in each server rack to manage power delivery and maintain efficiency. This approach helps maximize capacity and supports reliable power distribution for all connected equipment.

Importance in Data Centers

A server power distribution unit plays a vital role in the overall power management strategy for data centers. It ensures reliable power distribution and supports efficient power distribution for every server rack. The following points highlight its importance:

• PDUs distribute power reliably to IT equipment in each server rack, ensuring a consistent supply.

Types of PDU

Selecting the right PDU for a server environment depends on the required features, density, and power management needs. Each type of PDU offers unique advantages for different server rack configurations and high-density environments.

Basic

A basic PDU provides standard power distribution to multiple devices in a server rack. It does not include monitoring or advanced features. Data centers often use basic PDUs in setups where loads remain predictable and cost efficiency is a priority. These units support high outlet density, making them suitable for smaller server rooms or less complex environments. Basic PDUs offer simple deployment and reliable power delivery but lack remote management or data collection.

Tip: Basic PDUs work best in stable environments where density and advanced monitoring are not required.

Metered

Metered PDUs add built-in energy meters for real-time power monitoring at the unit level. These features help data center managers track current usage and prevent overloads. Metered PDUs support high outlet density, making them ideal for midsize to large server deployments. Staff can view power consumption directly on the device, which aids in capacity planning and efficient power allocation. However, these units do not provide remote access or outlet-level control.

Smart

Smart PDUs, sometimes called managed or intelligent PDUs, combine monitoring and switching features. They enable remote management, outlet-level control, and integration with data center infrastructure management systems. Smart PDUs support high outlet density and suit high-density environments where precise power management is essential. These units improve energy efficiency, scalability, and reliability. They also provide historical data, alarms, and automation tools for flexible power management. Certifications such as UL, CE, and IEC CB Scheme ensure compliance and safety.

ATS

Automatic Transfer Switch (ATS) PDUs provide reliable power distribution by switching between two power sources automatically. This feature ensures continuous operation during power interruptions. ATS PDUs support real-time monitoring and remote management, making them valuable in high-density environments where uptime is critical. These units often appear in mission-critical server applications that require redundancy and high reliability.

Vertical vs. Horizontal

PDUs come in vertical and horizontal mounting options. Vertical PDUs, also known as zero-U PDUs, mount along the side of a server rack and save valuable rack space. They support high outlet density, often providing up to 60 outlets per unit. Horizontal PDUs mount within the rack’s U spaces and suit smaller server racks or specific equipment needs. Both types offer locking features and color-coded sections for easy identification in high-density environments.

Note: Data centers often choose vertical PDUs for high-density environments to maximize space and outlet capacity.

Power Distribution Unit Buying Guide

Capacity and Load

Selecting the right PDU starts with understanding the total power requirements of your server environment. Data center managers should calculate the combined load of all equipment, including servers, switches, and storage devices. Always choose a PDU with a power rating higher than the total calculated load to prevent overloading. Consider the type of power supply available—single-phase or three-phase—as this determines the PDU type needed. Assess the number and type of outlets required for current and future needs. Planning for growth ensures the PDU can handle additional devices as your data center expands. High power capacity supports scalability and reduces the risk of downtime.

Tip: Always plan for at least 20% extra power capacity to accommodate future upgrades and unexpected load increases.

Form Factor

The form factor of a PDU impacts installation, scalability, and cable management. Horizontal PDUs mount within the rack and typically offer 6 to 16 outlets, occupying 1-2 rack units. Vertical PDUs, also known as zero-U PDUs, mount along the rack’s side and can provide up to 60 outlets without consuming valuable rack space. Vertical options improve airflow and support high-density server environments. The choice between horizontal and vertical depends on rack space, outlet needs, and future expansion plans.
