NTT Communications Launches Tokyo’s Largest scale-Data Center

TOKYO, JAPAN – NTT Communications Corporation (NTT Com) announced that today it launched its Tokyo No.6 Data Center in Tokyo, a cost-efficient, user-friendly, disaster-resistant facility with a total floor area of 22,000 square meters, enough to accommodate approximate 3,000 racks, making this Tokyo’s largest scale-data center. NTT Com will leverage this highly reliable, scalable, state-of-the-art facility to further grow its worldwide data center services, which are now marketed under the newly launched Nexcenter™ brand.

Corporate needs for cloud services, ICT outsourcing, disaster recovery and other ICT-related services have been rapidly growing due to the needs for ICT environment optimization and planning for major natural disasters. NTT Com operates data centers in more than 140 locations, amounting to a total server room floor area of over 170,000 square meters. Under its newly launched Nexcenter™ brand, NTT Com is striving to offer enhanced data center services of even higher quality than before. Tokyo No.6 Data Center is the first of several major NTT Com data centers that will combine globally standardized service agreements, service level agreements (SLA) and customer portals with special cost-reducing features, such as advanced air conditioning systems and virtual-network-based global seamless services, including hybrid clouds.

Leading features of Tokyo No.6 Data Center follow.

Accessible, cost-performance urban data center

NTT Com’s new data center is just seven minutes on foot from the centrally located JR loop train line, making it highly accessible even during emergencies. The building’s energy- and space-efficient design features a large rotary UPS. Racks handle equipment up to 1.5 times larger than the conventional racks, helping to lower user costs by as much as the half compared to previous rates.

Robust anti-earthquake designs

Tokyo No.6 Data Center’s seismic isolation structure can reduce the impact of earthquakes by at most 80%. Resistance is rated to withstand forces as powerful as those generated by the unprecedented Great East Japan Earthquake of 2011. An extra-strong ground helps to prevent liquefaction, and the building foundation is 1.4m higher than ground level to avoid flooding. Redundant major power supply and air conditioning systems strengthen reliability, and the facility has a direct connection to a large aseismic cable tunnel that protects lead-in cables from damage by earthquakes or drilling.

Top-level power usage effectiveness

Power usage effectiveness (PUE) is designed to rated at 1.2, the highest level among data centers in Japan. The facility features energy-efficient water-cooled air conditioning, low-power-loss rotary UPS, reduced-power air conditioning system through use of cooler outdoor air and efficient air-flow management to prevent the circulation of server-generated heat.

Flexibly customizable equipment

Equipment specifications for electric power, air conditioning, security can be flexibly customized to meet a customer’s specific needs and requests, such as redundant routes for internal power supply and communication systems by using multi-free shafts in a colocation room, additional local air conditioning equipment and security gates that allow only one person at a time.

Annex office building

A 2,000 square meters annex office building for customers is available in Tokyo No.6 Data Center. Office-rack connection and uninterruptible power sources are available for business continuity planning and more convenient monitoring and maintenance of customer systems.

Scalable, high-quality network environment

The new data center uses NTT Com’s Arcstar Universal One enterprise network service and other global network services for connectivity with global data centers and virtual networks to enable flexible establishment and operation of system expansion, system distribution and disaster-recovery sites.

Going forward, NTT Com will continue to offer leading-edge data center services, now under the Nexcenter™ brand, to help customers grow their businesses.
