NTT SmartConnect Corporation (head office: Osaka City in Osaka; president: Shuji Akiyama, hereinafter called “NTT SmartConnect”) will open large-scale Sonezaki Datacenter (provisional name) in a neighboring area of Dojima in April 2022.

1. Background to the opening

NTT SmartConnect has deployed six data centers in the center of Osaka and the Dojima, Kitahama, and Nipponbashi areas since the establishment in 2000. Being valued with high-quality, low-cost optical fiber cabling in Dojima and the surrounding areas, our data centers have grown into the largest internet exchange*1 in western Japan.
With the increased demand for internal and external video live service by companies and increased traffic from the increase in video streaming service by consumers staying at home due to COVID-19, and the development of IT technologies, including 5G and automated driving, it is expected that internet traffic will continue to increase in the future.
NTT SmartConnect, which has been responding to such demands by establishing the Nipponbashi Data Center in May 2021, will ensure a response to customers’ demands, including facility expansion, and ISPs’ demands to expand their business into the Kansai area by establishing the large Sonezaki Data Center (provisional name) in a neighboring area of Dojima.

2. Major features of the Sonezaki Data Center (provisional name)

(i) Housing service available to meet hyper-scale requirements

The Sonezaki Datacenter is planned to support racks from a unit of one rack to more than 100 racks and is scalable up to about 3,650 square meters per 10.0 MW to flexibly respond to customer requests, including housing rack specifications and positioning. The rack size in the standard housing service is 700 mm wide and 1,100 mm in depth (can be scalable up to 1,200 mm as an option), the power cables and network cables are provided in different routes, and customers can safely use the service. It also supports high load power at more than 20 kilowatts per rack.

(ii) Directly connected to the Dojima, Kitahama, and Nipponbashi Data Centers, allowing interconnections between businesses

The optical fiber cabling service Dojima Connect*2 allows interconnections between customers in the Dojima, Kitahama, and Nipponbashi Data Centers. The data centers are directly connected through Todo*3 and redundant path to ensure high reliability and security.
Also, the optical fiber cables between the buildings have the minimum number of fusion splicing points, which provides the service with the same transmission loss and high-quality as the facility environment between adjacent building in Dojima.
Moreover, the service fee of Dojima Connect, which connects our data centers, is flat and provides easy accessibility to customers who are looking for network interconnection points in Osaka.

  2. *3Underground tunnel dedicated to network connection where cables between communication sites to be installed

(iii) Disaster-tolerant facility specifications

The Sonezaki Data Center (provisional name) is earthquake-proof and tolerant of upper-6 intensity earthquakes, providing 72-hour continuous oilless operation using in-house power generation and power supply from a different substation. The data center is located in an area where the potential of tsunami hazard is low on hazard maps, and significant facilities are installed on the second floor or upper floors in the case of a river flood. Also, it is designed to allow as many UPSs (uninterruptible power-supply systems) as needed to be installed per floor and provides high reliability.

(iv) Reliable support services

The Sonezaki Data Center provides manned 24/7 maintenance and support services by our technical support. It has English speaking staff and a Web support desk in place for overseas customers’ safe use.
