There’s no right or wrong answer. Like most things, it’s horses for courses. If you can build a data centre at the foot of the Great lakes in Illinois where there’s lots of wind and lots of cold, then fast-flowing clean free cold air works just fine. If you build a data centre all at ground level in a green field in England, water gives the best efficiency. For us at City Lifeline, as a data centre in the centre of London, we use all DX (aircon). Just the thought of a water leak on the top floor with 4 floors of racks underneath would stop me sleeping for years.
