Power distribution units (PDUs) are essential components for any data center. They ensure reliable power delivery to critical IT and networking equipment. However, not all PDUs are created equal. Metered PDUs offer unique advantages and functionalities that meet the evolving demands of modern data centers.
The primary purpose of a PDU is to provide a seamless connection between your facility’s power supply and the equipment inside your data center. That said, new technologies have turned PDUs into crucial management tools that do much more than route electricity.
The types of PDU in data center environments generally fall into four main categories, each of which serves different needs:
At first glance, a basic PDU and a metered PDU might seem similar: they both distribute power to racks of equipment. On closer inspection, though, the two serve distinct purposes based on their capabilities.
Metered PDUs shine where power visibility is crucial. By providing detailed readings of overall energy usage, data center managers can track trends, prevent overloads, and detect inefficiencies.

Features
Use Cases
Managed rack PDUs take functionality even further by incorporating additional layers of control, monitoring, and flexibility. These options ensure that enterprises can adapt to changing data center demands with ease.
A smart PDU is an advanced power distribution unit equipped with monitoring, analytics, and remote management capabilities. Unlike traditional PDUs, smart PDUs allow facility managers to track power usage, identify inefficiencies, and make data-driven decisions to optimize energy consumption by doing the following:
By monitoring and allocating power effectively, PDUs ensure that servers, storage systems, and networking equipment all receive stable power.
Backup PDUs or redundancy features protect critical systems during outages and enable business continuity.
Through advanced reporting and analytics, smart PDUs provide actionable data to improve energy efficiency, reduce waste, and lower costs.
Smart PDUs represent the next stage in the PDU evolution, combining metering, switching, and advanced analytics in a single unit. They can transform your data center's operations through:
Smart PDUs provide granular energy consumption data at the outlet level. This facilitates proactive resource management and capacity planning.
Whether they’re rebooting unresponsive devices, adjusting power settings, or monitoring trends, smart PDUs allow IT administrators to manage everything remotely. This reduces the need for physical interventions and minimizes downtime.
Advanced alerting features in smart PDUs notify operators of potential overloads or irregularities, enabling them to take immediate action.
By tracking and managing usage patterns, smart PDUs help data centers use energy more efficiently, reducing carbon footprints and supporting sustainability goals.
Smart PDUs are built to scale with growing data center demands. They are modular, which makes it easier for facilities to adapt as new technologies emerge. This ensures your infrastructure remains resilient as your workloads increase.
Data-driven insights provided by a smart PDU enable businesses to strike a balance between performance and efficiency, making them a worthwhile investment for long-term success.
Metered and smart PDUs are indispensable tools for any data center aiming to improve its energy efficiency, sustainability, and reliability. By leveraging their advanced capabilities, you’ll have full control over your power consumption, prevent potential risks, and enhance operational excellence.
