Fujitsu cooling technology for data centers can halve energy consumption

Data centers of large-scale, internet-based companies could halve their expenditure on energy for cooling with a solution developed by Fujitsu.

The company has stated that its Cool-Central Liquid Cooling Solution helps achieve such savings. Currently, data centers typically utilize about 40 percent of their total power consumption on cooling.

Fujitsu’s solution will not only help reduce spending on electricity but also lead to lesser consumption of dirty power.

According to the statement, another of its solutions, the liquid-cooled FUJITSU Server PRIMERGY CX400 M1, is able to increase data center density by five times.

This helps companies in the high-performance computing segment as it increases processing power per unit area. The company states that its technology will enable accommodating 160 Intel Xeon processors and 1,280 memory modules per standard rack.

The hike in density would mean consumption of 30 kW per rack, which is projected to increase to 50kW by 2016.

Fujitsu says liquid cooling will help keep data centers within an acceptable temperature range.

“In addition to maximizing rack density and lowering cooling and power costs, a much smaller investment is needed to build new data centers using liquid cooling compared with traditional air-cooled infrastructures,” the statement says.

The system is also capable of reducing the overall energy consumption by recycling waste heat in the form of water at 60 degrees Celsius to heat or cool offices, homes, or other facilities, Fujitsu says.

Uwe Romppel, Head of Product Management Server at Fujitsu, said the direct-to-chip liquid cooling has delivered Power Usage Effectiveness (PUE) close to 1, which indicates optimized use of energy in the data center.

The company claims that the energy efficiency of FUJITSU Server PRIMERGY systems has improved by a factor of 30 since the beginning of power and performance characteristic measurements in 2007.
