GDC - Osaka 5 Data Center

Convenient access from more than one train stations and railways
Seismic isolation structured purpose-built data center which stands earthquake of Japanese scale intensity level 7 (the level of Great Eastern Japan Earthquake in 2011)
Achieving PUE 1.3, the top level PUE among all data centers in Japan by adopting high-efficient water-cooled air conditioner, outdoor air cooling system, and end wall injection air conditioning
First NTT Com data center in Japan to have stable power supply from two different power substations.
Directly connected to robust cable tunnel preventing disaster risks.
Excellent connectivity with NTT Com's network services and cloud services.

Located at Osaka Metropolitan Area, diverse routes are available.
Easy access from central Osaka on foot even in emergency situation.
7 minutes from the nearest station
20 minutes by train from Shin-Osaka station
1 hour from Kansai International Airport
The site is located at 6 km from Osaka Bay and 3 km from the nearest river to prevent the water risks, and the data center could be in operation even in the unexpecting case

Osaka 5 Data Center can reduce seismic shocks to one-fifth and it can also suppress vertical shocks to prevent bad effects on customers' equipment, facilities and building.
Communication circuits are connected directly to secure earth-quake-proof cable tunnnels.
and to ensure reliability, Osaka 5 Data Center recieves power from two substations with redundant cable routes.
