Japanese technology company Fujitsu and its partner Fuji Electric Systems unveiled on Tuesday a package of solutions they said would reduce data center-caused carbon dioxide emissions by about 40 percent. The new solutions are a facility management system that visualizes data center energy use, a spot air conditioning system, noise-baffle-borne solar cells.
Kawasaki-based Fujitsu is currently deploying the technologies at an expansion of its data center in Tatebayashi, scheduled to open in November, according to a company statement.
The energy consumption visualization technology the data center management system uses includes a sensor network, a power distribution panel, optimization guidance for data center expansion and rack-mounted transformer boxes.
The sensor network is made up of tens of thousands of temperature and airflow sensors and Fujitsu’s proprietary wired “ad-hoc networking“ technology, which the company says enables a self-configuring network, eliminating the need for special design. The power distribution panel provides capabilities for detailed monitoring of each server’s load. It uses branch breakers with built-in current sensors and multi-point power collection equipment.
If an operator wants to expand the facility, the system can automatically calculate the most efficient wiring routes from the power distribution panel and breakers, best equipment placement, three-way power balancing and cooling requirements.
The new spot air conditioning system uses technology developed by Fuji, monitoring hardware utilization to balance spot and systemic air conditioning. It uses headroom above the racks. The system needs about 25 percent less energy than a system with spout below the floor set in a 1000-square-meter server room, Fujitsu said.
Fuji also developed the technology for mounting solar cells on vertical noise baffles. The approach uses lightweight film substrate solar cells which, combined with Fuji’s newly developed power conditioners, promise significant power savings.
