What Are the Best Practices for Energy Efficiency in British Data Centers?

April 17, 2024

In the digital age, where data is considered the ‘new oil’, data centers are the lifelines powering our digital lives. From cloud computing and online services to infrastructure systems and software, data centers are at the heart of it all. However, with great power comes great responsibility—especially when it comes to energy consumption and sustainability. In fact, the role of data centers in energy consumption is a major concern for not just the IT industry, but also for environmentalists and policymakers.

For UK-based data centers, the task is not just to ensure digital services are always on, but also to ensure these services are provided in an energy-efficient and sustainable manner. This article will explore the best practices for achieving energy efficiency in British data centers—focusing on solutions like green energy, cooling mechanisms, privacy concerns, and more.

Adapting Green Power Sources

As you strive to improve your data center’s energy efficiency, one of the first things you should consider is the power source. Traditional power generation methods contribute heavily to carbon emissions, thereby affecting the environment negatively. In contrast, green power sources such as wind, solar, and hydroelectric power offer a cleaner, more sustainable way to power data centers.

Many UK-based data centers are already exploring this route. For instance, some have begun sourcing their power from renewable energy providers, while others have invested in on-site renewable energy generation. However, this transition isn’t just about ‘going green’—it’s also about improving efficiency. Renewable energy sources can provide a more reliable power supply, reducing the risk of outages and thereby improving overall operational efficiency.

Implementing Efficient Cooling Systems

Cooling systems are another critical aspect of data center energy efficiency. High-performing servers generate a lot of heat, and if not properly managed, this can lead to hardware damage and reduced system performance. Traditionally, data centers have relied on air conditioning to keep server rooms cool. However, these systems consume a lot of energy.

In response to this problem, many data centers are now implementing more energy-efficient cooling strategies. For example, some are using free cooling—where outside air is used to cool the servers. Others are using liquid cooling systems, which can be far more efficient than air conditioning. Another approach is heat re-use, where the heat generated by the servers is used for heating other parts of the building.

Optimising Infrastructure Systems

Infrastructure systems play a crucial role in the overall efficiency of a data center. Optimising these systems can lead to significant energy savings. This includes efficient server utilisation, virtualisation, and load balancing.

Server utilisation refers to the amount of server capacity that is being used. By increasing server utilisation, data centers can deliver the same services with fewer servers, thereby reducing energy consumption. Virtualisation is a technique that allows multiple virtual servers to run on a single physical server, thereby increasing utilisation. Load balancing, on the other hand, involves distributing work evenly across servers to avoid overworking and overheating.

Embracing Cloud Computing

Cloud computing has emerged as a viable solution for energy efficiency in data centers. By shifting computing workloads to the cloud, data centers can reduce their on-site server requirements, thereby reducing their energy consumption.

Furthermore, cloud providers often have the resources to invest in energy-efficient infrastructure and practices. This means that by using cloud services, you might actually be contributing to overall energy efficiency in the IT sector. However, it’s essential to choose a cloud provider that prioritises sustainability and has strong privacy protections in place.

Building for Sustainability

Last but not least, sustainability should be at the heart of data center design and operation. This means thinking beyond just energy efficiency. It means considering the entire lifecycle of the data center—from construction to decommissioning.

Building for sustainability involves using environmentally friendly materials in construction, minimising waste during operation, and planning for responsible decommissioning. It also involves engaging with stakeholders, including local communities and regulators, to ensure the data center’s operations are in line with wider sustainability goals.

In conclusion, there’s no single solution to improving energy efficiency in data centers. It requires a holistic approach that considers every aspect of the data center’s operations. However, by embracing green power sources, efficient cooling systems, optimized infrastructure systems, and cloud computing, and by building with sustainability in mind, it’s possible to significantly reduce a data center’s energy footprint while still delivering reliable, high-quality digital services.

Utilising DCIM Software to Enhance Energy Efficiency

Data centre infrastructure management (DCIM) software is a powerful tool in enhancing energy efficiency in data centres. This software aids in monitoring, managing, and controlling data centre resources and energy consumption. DCIM software helps to provide real-time information about the functioning and energy use of IT equipment and facility infrastructure.

DCIM software is a unique combination of IT and facility management to help data centres ensure reliable uptime, improve capacity planning, and extend the life of the equipment. It provides a means to check, track, and manage power usage effectiveness (PUE), a critical factor in ascertaining the energy efficiency of a data centre. By using such software, operators can have a closer look at the time used by servers and other equipment, making sure their operations are as energy-efficient as possible.

Implementing DCIM software also helps to identify underutilised servers, enabling operators to effectively manage space and power within the data centre. Besides, it assists in the early detection of problems that could lead to energy wastage, hence promoting proactive management of the data center.

However, in using DCIM software, the privacy policy must be checked and adhered to ensure that data is not compromised. It is also essential to make sure that the communications time of the software does not interfere with the data centre’s regular operations.

Adopting Best Practices for Energy Efficiency: A Continuous Process

Achieving energy efficiency in data centres does not happen overnight. It is a continuous process that requires consistent evaluation and adaptation of best practices. Despite the complexities involved, the benefits of an energy-efficient data centre far outweigh the challenges.

Embracing green power sources, employing efficient cooling systems, optimising infrastructure systems, and adopting cloud computing are crucial steps towards achieving energy efficiency. Furthermore, building with sustainability in mind and utilising tools like DCIM software can significantly improve the energy performance of a data centre.

However, it is crucial to note that these practices are not a one-time check. Regular audits should be conducted to ensure all systems are operating at their peak efficiency. Using DCIM software, operators can perform a time check to ensure that the energy consumption of the data centre is within the desired limits.

In conclusion, energy efficiency in data centres is a pressing issue that requires continuous efforts and innovative solutions. It demands a comprehensive approach that encompasses the use of renewable energy, efficient cooling systems, infrastructure optimisation, cloud computing, and sustainable building practices. With the right strategies in place, data centres can significantly reduce their energy consumption and carbon footprint, contributing to a greener and more sustainable digital future.

Remember, the path to energy efficiency is often a journey rather than a destination. It requires commitment, innovation, and adaptation over time. As the world continues to evolve digitally, so should our efforts to make data centres more energy-efficient.
