NTT Communications (NTT Com) opened its Tokyo No.6 Data Center, a disaster-resistant facility with a total floor area of 22,000 square meters, enough to accommodate approximate 3,000 racks.
The new facility, which ranks as Tokyo’s largest data center, will deliver cloud services, ICT outsourcing, disaster recovery and other ICT-related services
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.
NTT Com is now marketing its data centers worldwide under a new “Nexcenter” brand. NTT Com operates data centers in more than 140 locations, amounting to a total server room floor area of over 170,000 square meters.
Highlights of the new building:
Located just seven minutes on foot from the JR loop train line, making it highly accessible even during emergencies.
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.
Aseismic 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.
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.
