Chiller-Free Design to Provide 100% Free Cooling

Petroleum Geo-Services (PGS), the oil exploration surveyor, has appointed Keysource to expand its data centre at its head office in Weybridge, Surrey. The latest development will incorporate an innovative chiller free design that will deliver 100 per cent indirect free cooling by taking advantage of the ambient outside temperatures. This will enable PGS to reduce capital and ongoing expenditure without compromising on availability or performance.

The data centre expansion is due for completion at the beginning of 2014 and will increase the capacity to 2.7MW of IT load, 50 per cent more than the original design. All cooling plant will be located externally to the building allowing PGS to maximise the internal rack footprint. This will include 188 rack positions, supporting up to 30kW per rack, to allow PGS to take advantage of high performance computing.

Mike Turff, Global Compute Resources Manager at PGS told ThisWeekinFM: “Keysource has developed a second phase solution that will build on the initial facility to deliver enhanced performance. This will enable us to effectively grow our IT operations in this data centre.”

 Andy Hayes, Director of Keysource said: “Growth and changing requirements meant PGS needed to support a higher facility IT capacity than the original Phase 1 design, whilst achieving added improvements in efficiency and performance. The flexibility and scalability of our modular approach means we have been able to develop a chiller-free design that will meet PGS’ needs.”

Opened in 2008, the initial phase of the PGS data centre was the first facility to use an ecofris (www.ecofris.co.uk) cooling solution. It was designed for 600kW of IT from day one and scalable to 1.8MW, and has delivered an annualised PUE of 1.15 since becoming operational. The design and ongoing optimisation has saved over six million kWh in annual power consumption when compared to the company’s previous data centre.

 

With headquarters is in Oslo, Norway, Petroleum Geo-Services helps oil companies to find oil and gas reserves offshore worldwide. PGS has a presence in over 25 countries with regional centers in London, Houston and Singapore. The company has 14 offshore seismic vessels, 21 data processing centers and 35 offices worldwide, employing over 70 nationalities
