Japan : NTT Communications to Construct Osaka 5 Data Center

June 10, 2014



NTT Communications Corporation (NTT Com), the ICT solutions and international communications business within the NTT Group, announced today that it will begin constructing the Osaka 5 Data Center in the heart of Osaka, aiming at commencing operations in the first quarter of calendar 2016. The facility will offer approximately 3,700 m2 of server room, equivalent to 1,600 racks.

This next-generation Osaka 5 Data Center will be the newest addition to NTT Com s Nexcenter brand of data center service. It will provide high quality, cost efficiency and flexibility in cloud and colocation services that customers can use to create hybrid cloud environments connected to cloud infrastructure and virtual networks. NTT Com s virtual networks incorporate SDN (software-defined network) and Open Flow technologies to enable users to change system configurations flexibly and on demand.

Low-cost operations realized with latest technologies and best practices NTT Com, leveraging its vast experience and know-how concerning data center construction and global operations, has designed Osaka 5 Data Center with energy-efficient air conditioning systems that incorporate water cooling, end wall injection air conditioning and outdoor-air use to reduce power consumption.

The facility, which also features highly efficient power equipment, theoretically will be capable of a 1.3 Power Usage Effectiveness (PUE) rating, which would be a first in the surrounding Kansai region and one of the highest levels in Japan. PUE is calculated by total power consumption divided by ICT equipment power consumption, so the lower the number the higher the energy savings. Current data centers target PUE ratings of under 1.5.

Compared to similar facilities, construction and operating costs will be reduced by some 30% through use of an existing building foundation, adoption of mega-structure designing to reduce steel consumption while maintaining rigidity, and a highly efficient facility layout.

Optimum disaster-recovery features for business continuity planning (BCP) Located in the heart of Osaka, Osaka 5 Data Center will be easily accessible from multiple railway stations. Even if public transportation were not available during an emergency, the data center will be within walking distance of many principal areas of Osaka.

The building is seismically engineered to withstand earthquakes equal to the Kobe Earthquake of 1995 or the Great East Japan Earthquake of 2011. It also is calculated to minimize impact to customer equipment in the case of large vertical movements that are forecast possibly to occur in an earthquake directly beneath the area s Uemachi fault. Furthermore, the facility is connected directly to a large quakeproof communication cable tunnel that is designed to protect cables during earthquakes, as well as road construction.
