AMSTERDAM and LONDON, September 3, 2010 – Hitachi Europe Ltd. (hereinafter called Hitachi), and GREEN DATA SYSTEMS (hereinafter called GDS) announce the opening of a highly energy efficient data centre in Deventer, The Netherlands. This is a result of a strategic partnership between Hitachi and GDS for the collaboration and deployment of highly energy efficient data centres.

The data centre will be opened on September 23, 2010. During the day customers will have the opportunity to experience Hitachi's technologies for energy efficient data centres.

GDS, one of the investors in the ECO2DC initiative, is planning to develop the most energy efficient data centre in Europe, based in The Netherlands. Hitachi's modular type data centres are thought to be an effective solution for energy efficiency. GDS and Hitachi entered a partnership earlier this year to initiate further development in this field.

In 2007, the Hitachi Group launched its energy efficient data centre project, which was driven by the increasing demand for IT equipment and facilities in data centres and the need to lower the environmental impact of this technology.

Hitachi later developed a modular data centre solution, which has been available in Japan since January 2009. The solution optimises the configuration of the cooling units to obtain the highest level of power efficiency in a high-density arranged data centre. This enables data centre operators to boost the utilisation of space to the highest potential, while reducing CO2 emissions considerably.

GDS pursues energy efficiency in data centres and provides customers with optimal data centre capacity, cooling, managed services, SAN, security, server, software and data storage technology as well as services for green data centres and resellers in European countries such as Belgium, Germany and The Netherlands. ECO2DC is a leading data centre services provider aiming to build and operate the most energy efficient data centre in Europe.

Wessel Graatsma, CEO of Green Data Systems, said: “We are very enthusiastic about the opening of this unique and highly energy efficient data centre. We believe Hitachi's cooling technology and operating know-how for data centres contribute to our green data centre business. It has potential to increase energy efficiency, which is a key requirement for our customers”.

Akira Shimizu, Managing Director of Hitachi Europe Ltd., said: “We are very pleased with the opening of the facility and the strategic partnership with Green Data Systems. GDS is one of our excellent distributors in the EMEA region and the contribution to reducing environmental impact is remarkable. As part of this partnership, we will contribute to society by decreasing our customers' ecological footprint. Further progress in our data centre technology will enable the expansion of Hitachi's modular data centre business in Europe”.

Hitachi's cooling system, which is based on the modular data centre, is housed in Deventer, The Netherlands. Hitachi will obtain operating data from the data centre for research purposes to further improve energy efficiency. The site will also be a showcase of Hitachi's technologies for energy efficient data centres to customers throughout Continental Europe.
