Power and automation technology group ABB and Green, an information and communications technology service provider in Switzerland, announced the official opening of Green’s Zurich-West data center expansion. Based on direct current (DC) technology, the new facility employs HVDC-capable HP servers, and is touted as the most robust application of DC power in a data center to date.
“The implementation of 380 volt DC technology in our data center is part of our long-term energy optimization strategy, a big step that has set a new standard in the industry,” commented Franz Grueter, CEO of Green. “When fully loaded, the system will result in energy savings of up to 20 percent in power consumption from grid to chip and in cooling.”
ABB installed the one megawatt DC power distribution solution for the 1,100 m2 expansion of the 3,300 m2 Zurich-West data center. It was engineered to Green’s strict ecological standards by ABB with support from Validus DC Systems, an ABB company, and includes a service level agreement. According to ABB, performance tests showed that Green’s new power distribution system is 10 percent more efficient than for comparable alternating current (AC) technology. In addition, investment costs for the system were 15 percent lower than for an AC system.

“Across all our business areas, customers are asking for improved reliability and energy efficiency, and DC power is an effective solution," said Tarak Mehta, head of ABB’s Low Voltage Products division. "Zurich West will serve as a global showcase to demonstrate that DC is a complementary technology in data centers as it enhances reliability while minimizing footprint, installation and maintenance costs.”
With the addition of almost six million new servers every year, data center energy demand is increasing at a rate of more than 10 percent annually, requiring more efficient and reliable solutions, notes ABB. The company contends that DC systems are less complex than AC systems, making fewer power conversions. Such facilities as much as 25 percent less space, and reduces equipment, installation, and real estate and maintenance costs. The project underlines ABB’s goal to create new power options through expanded DC applications. The company pioneered technologies that made conversion between AC and DC systems possible and was the first to commercialize long distance high-voltage DC power transmission.
Also for the facility expansion, HP provided its HVDC-enabled servers and storage platforms, including the HP X1800 G2 Network Storage System, HP DL385 servers, and the HP BladeSystem c3000. These systems represent the beginning of HP’s strategy to enable enterprise IT with support for high-voltage DC power.
"Green was looking for an IT partner that could provide HVDC-enabled IT solutions to meet its specific data-center needs," said Ron Noblett, vice president, Infrastructure and Storage, HP. "At the heart of HP's Converged Infrastructure strategy is our commitment to develop new energy-saving technologies that can lower data-center capital costs, as well as ongoing operations costs and complexity."
