Boston IT Solutions (India) Private Limited unveiled the latest evolution in their range of liquid cooled servers, featuring patented "modular liquid immersion" technology from Iceotope Ltd, that leverages the thermal superiority of liquids to reduce the operating costs of large-scale computing facilities such as data centres.

Each server motherboard is completely immersed in an individually sealed bath of an inert liquid coolant which passively transfers heat away from the sensitive electronics to a tightly integrated heat exchanger formed by the wall of the bath where water is continuously recirculated and cooled. Compared to traditional air cooling systems, the two liquids are thousands of times more effective in capturing and transferring heat, thereby requiring much less energy to run the overall system as the water can be allowed to run warmer whilst still providing adequate cooling.

Cooling typically accounts for 30% or more of electricity operating costs i

n traditional air cooled data centres due to the requirement to operate Computer Room Air Conditioning (CRAC) units and refrigeration plant (chillers) to circulate large volumes of cold air to the servers. A typical air cooled data centre with around 1000 servers would require approximately 1 megawatt of electricity to operate, of which around 300 kilowatts would be used on cooling.

The typical 3 year cooling cost would therefore be around $788,400. By eliminating the requirement for CRAC units and reducing the need to operate chillers by exchanging heat directly with the air outside the data centre (so-called "free cooling"), the exclusive use of liquid cooling could reduce the 3 year cooling cost to around $52,560; a 93% ($735,840) cost reduction compared to air cooling. By enabling servers to be packed more tightly without compromising the cooling efficiency, the same approach could reduce the space required for the servers by 84%.
