Outside air is drawn into the facility to cool the thousands of servers powering the company’s “Live” suite of online services for users in Europe, the Middle East and Africa. Microsoft also said it can run its server rooms at temperatures of up to 95 degrees F (35 degrees Celsius), much warmer than most data centers, which typically range between 68 and 72 degrees. Free Cooling Drives Energy Savings Using outside air in data center air conditioning – a practice known as “free cooling” or air-side economization – allows facility owners to dramatically reduce the amount of energy used in cooling. Chillers, which are used to refrigerate water, are widely used in data center cooling systems but require a large amount ... (Read Full Article)
