Innovation ousts orthodoxy. Soft-switch has replaced telephone exchange equipment. Undersea optical fiber cables have marginalized satellites in intercontinental and transcontinental connectivity. Terrestrial optical fiber networks – along the highways, railway tracks, power grids and gas pipelines – are replacing microwave radio links. All these physical networks lead to data centers at home and abroad.
Thousands of servers, routers and storage equipment in the data centers – being housed in the aisles of racks – keep us uninterruptedly connected to internet. Blowers fitted with these devices continuously exhaust hot air to keep their internal components cool. Therefore, highly sophisticated air cooling systems are indispensable to maintain standard operating temperature in data center facilities.
Air cooling plants consume nearly 40 per cent energy of a data center. Its internal temperature rises, as hardware keep adding to meet unstoppable exploding demand of data by the fixed and mobile networks. Therefore, the capacity of air cooling plants along with floor space keep expanding proportionately. Such continuous expansion of costs threatens the business model of internet.
Immersion Cooling technology reduces the data centers’ air cooling energy footprint up to 95 per cent and shrinks required floor space by ten-times. Developing Asia historically struggles in both the fronts. As a result, data center remains the biggest roadblock to broadband’s universal access in Asia. And unsurprisingly Asia Cloud Computing Association has placed ‘energy sustainability’ at the top of their policy recommendations.
Asian policymakers should consider Immersion Cooling as one of the leading green solutions for sustainable growth of ICT. Eliminating the consumption of power to cooldown the data centers is a strategic imperative. Lighting up the optical fibers keeping vast population in the darkness is anything but development.
