FEATURE FEATURE As data centres are one of our most heavily relied upon resources, it is important that they operate sustainably. Matthew Underhill, Head of Infrastructure, Alfred H Knight, discusses his approach to greener data centre operations and offers his best practice advice for improving energy efficiency in the data centre space. Operating sustainably in the data centre space As I consider ways to develop a more sustainable approach to data centre operations, I believe this starts from the ground up. Ensuring that the building itself is energy efficient is the very first step during the design phase. Making sure that the building materials are sustainably sourced is also vitally important to ensuring a greener approach. Utilising clean and renewable energy is vital to running a green data centre and reducing carbon emissions – coupling this with energy-efficient fuel cells can also make this more efficient, with increased resiliency. Thermal containment offers improved efficiency by containing either hot or cold air – or both – into their specific areas. This improves the efficiency by offering greater control of the inlet air temperature, helping to eliminate hotspots – making the requirements more predictable. In turn, this can enable increased utilisation of free air cooling. Free air cooling uses low outside air temperatures to help cool the data centre – and is one of the reasons that the Nordic countries are favoured for big data centre installations. Granted, this air still needs to be filtered and moisturised and this process requires much less energy over typical cooling methods. To increase power efficiency, organisations can use AI analytics to monitor the power coming in and how it is consumed. Firstly, knowing what you are consuming is a start as it gives a target in which to aim for. Utilising AI controls not only the power, but the entire data centre.
