ATR chooses PRIMERGY Servers for optimizing Datacentre power consumption

"We plan to reduce power consumption by 30% by end of FY2013 and 40% by end of FY2014, with a long term goal of a 70% reduction in FY2015. Our objective is achievable using the High Voltage Direct Current +12V approach and wall-mounted air flow system."

Prof. Morito Matsuoka, Osaka University, The Cybermedia Center (CMC)

The customer

Keihanna Datacenter, established as the Ministry of the Environment’s technology verification project, started verification tests on 15th July 2013. The Keihanna Datacenter was built at the Advanced Telecommunications Research Institute International (ATR) on 1st October 2013. The data center operates as part of the Japan Ministry of the Environment’s FY2013 project to ‘Strengthen measures to reduce C02 emissions through technological development and verification’, and is equipped with the newest technology for linking DEMS (Datacenter Energy Management System) and VM (Virtual Machines).

The challenge

  • Reduce power costs with an efficient data center facility
  • Include voltage and AC/DC conversion power module for each server
  • Introduce new efficient data center operations including effective exhaust heat utilization

The solution

FUJITSU Server PRIMERGY RX200 S7 was selected for the Datacenter Energy Management System (DEMS) as its Power Control Unit functionality to improve the energy efficiency via a HVDC (High Voltage Direct Current) +12V power supply and reduce overall TCO.

The benefit

  • 12 DC power supply improves energy efficiency (AC/DC) to 90%
  • Reduce TCO by combining highly efficient intense power supply (HVDC) and direct current power supply compatible server
  • FUJITSU Server PRIMERGY RX200 S7 operates in environments over 40°C
  • Reduce power consumption by 30% in FY2013 and strive for a 70% reduction in FY2015
