Sept. 19, 2013 /PRNewswire/ -- NTT Communications Corporation (NTT Com), the network, cloud and international communications business within NTT Corporation (
TOKYO: 9432; NYSE: NTT), announced on
September 19 that Gyron Internet Limited, an NTT Com group company and the UK's leading data center service provider, will start construction of a new data center, UK Hemel Hempstead 3, to meet the growing demand for scalable and reliable colocation services.
Located at a 38,500 square-meter site near the two Gyron data centers already operating in
Hemel Hempstead, northwest of
London, the new facility will start providing approximately 10,000 square meters of server room from spring 2015, more than doubling the total server room area in the UK.
By using advanced green technology for cooling such as end wall injection air conditioning, water-side economization and chimney racks to expel heat, the facility achieves a power usage effectiveness (PUE) of under 1.2, putting it among the most energy efficient data centers in the UK. It will also be the first data center in the UK to offer the option of a chillerless cooling system, which opens up approximately 30% more energy capacity for ICT systems without expanding its power system. The facility further reduces NTT Com's environmental load by using rain water in the air conditioning, generating electricity from solar panels, and using heat from the server equipment to warm office areas in the winter.

By incorporating a modular design concept, electric power, air conditioning and communication equipment are scalable in each server room, and redundancy systems can be freely set. Tier IV upgrades are also available as customers require. Moreover, the facility will incorporate security measures beyond the industry standard, including a four-meter-high peripheral fence, barriers against vehicle attacks and fire-prevention equipment installed in each module.
