Data centres are at the heart of modern society’s technological advancements, powering the online services that we all use every day. However, as the amount of digital data continues to grow, so does their power consumption. A considerable portion of this consumption is used for cooling, lighting, and powering the IT infrastructure, but it’s often overlooked how the power distribution system contributes to energy usage. In this blog post, we’ll explore the power distribution system in data centres and how it’s designed to maximize efficiency.
A power distribution system is responsible for distributing the electric power that data centres need to operate. The system typically involves a transformer that converts the high-voltage electrical power supplied by the energy grid to a lower, more useful voltage that can be safely used within the data centre’s IT infrastructure. The power is then usually distributed across each server rack via power distribution units (PDUs).
Power distribution units (PDUs) are components that manage and distribute power to the equipment contained within the server rack. The modern PDU has been developed with energy efficiency in mind. There is now a wide range of PDUs with advanced features such as intelligent load balancing that ensures the power consumed from each power outlet is closely managed to avoid over-consumption. PDUs can have intelligent power management systems that monitor and control power used by each server.
One of the most significant challenges in data centres is cooling. Air conditioning units consume large amounts of energy in data centres, but the heat generated by the IT systems can’t be ignored. This results in additional energy consumption to keep the centre’s IT systems cool. This is where the power distribution systems play an important role – power distribution units can include advanced thermal monitoring technology that senses the temperature in the server rack, alerting the cooling system to make necessary changes to maintain optimal cooling efficiency.
Another way to optimize the efficiency of power distribution in data centres is by adopting a modular design. A modular design means that new servers can be added to the IT infrastructure without expensive reconfiguration, reducing downtime and making it more convenient for data storage to expand. Similarly, when it comes to power distribution, a modular design is more scalable and enables businesses to grow and expand their power requirements in parallel with their data processing capacity.
Efficient power distribution is critical to optimizing the energy consumption of the modern data centre. The rise of intelligent power distribution units enables the management and distribution of power in real-time to minimize waste and over-consumption. Alongside this, a modular design for both power distribution and data storage capacity provides businesses with many benefits for increasing efficiency, scalability, and reducing downtime costs. Implementing energy-efficient power distribution systems will continue to be a growing concern in data centres, and powering the data centres of tomorrow will require smarter and more efficient ways to consume electricity.
