Unification of IT Systems and Facilities for Next-Generation Environmentally Friendly Data Centers

Fujitsu Laboratories is engaged in unified research and development on a global basis from low power consumption chips and system boards to server systems, networks and power-supply, cooling, and software technologies. We are taking a holistic approach to technology development and are building a value chain of energy-saving technologies. Leveraging this extensive expertise in technology development, we are now developing elemental technologies for achieving compact, next-generation environmentally friendly data centers that unify facility functions including power-feeding and cooling with information technology (IT) equipment such as servers, storage drives, and network devices. This article introduces Fujitsu's pursuit of high energy-saving performance in data centers through diverse technologies such as micro-channels for efficiently transferring heat from central processing unit (CPU) chips to cooling water, a high-efficiency green uninterruptible power supply (UPS) integrated with each server's power supply unit, multipoint temperature measurement using optical fiber for real-time visualization of the spatial temperature distribution within the data center, and simulation techniques for achieving efficient operation of a data center's IT systems and facilities.
