Low latency and instantaneous communication, coupled with rising demand and the need for data center growth, have changed the way the data centres need to operate. With nearly 40 per cent of data center cost going to cooling power a recent analysis conducted by a European engineering firm uncovered potential worldwide cooling energy savings over $1.7 billion and even more promising carbon emission reduction of 3.7 million tons are achievable. Solutions such as airflow management, optimisation, artificial intelligence, machine learning, microgrids, renewable energy, virtual power, and new cooling technologies, are allowing data center owners and operators to account for every single watt of power entering their facility and in turn safely squeezing out every drop of efficiency possible. Becoming energy efficient and sustainable makes commercial sense as much as it does environmentally! Measure, manage, record, adjust, and recycle!
