(Bloomberg)—Some UK knowledge facilities have a low-tech option to keep away from meltdowns throughout this week’s warmth wave: spraying the roof-mounted air con models with water.
“Many knowledge facilities in London can have individuals on the roof with hoses in the meanwhile,” stated Adrian Trevelyan, After Market Director at Airedale Worldwide, which offers and maintains cooling techniques for knowledge facilities.
Small knowledge facilities in dense city areas operating near full capability are probably to wish emergency hosing throughout a sizzling spell. The spray lowers the ambient temperature across the air con unit’s coils to make sure they proceed to dissipate warmth successfully, Trevelyan stated. He declined to call any particular corporations adopting this system, however stated that it was taking place “throughout the M25 and into the Metropolis.”
Hyperscale knowledge facilities run by expertise giants typically use huge quantities of water — Google struck a deal within the US that ensures it 1 million gallons a day to chill one knowledge middle. Due to their giant dimension, they’ve house so as to add further cooling capability to deal with temperature spikes. Nonetheless, they aren’t resistant to overheating: on July 10, there was an influence outage at an Amazon Internet Providers knowledge middle in London on account of what the corporate described as a “thermal occasion.”
The hose strategy is a “Heath Robinson answer,” stated Sophia Flucker, director at knowledge middle consulting agency Operational Intelligence, which mimics the evaporative cooling techniques put in at different amenities.
“It’d get you out of a repair on a extremely popular day, however you’re probably shortening the gear’s life,” she stated, noting that if it’s executed in locations with exhausting water, comparable to London, it could actually result in a construct up of scale on the gear. Correctly designed evaporative cooling techniques use handled water, she stated.
Outages aren’t the one threat for knowledge facilities in a warmth wave, Flucker stated. Many “colocation” operators, who lease out capability to 3rd events, face monetary penalties for failing to maintain the corridor inside a contractually agreed temperature vary.
