IIJ to Build Scalable and Energy Efficient "Shiroi Data Center Campus"

Adopting System Module-based Construction and AI for Automation and Efficiency

February 6, 2018

TOKYO-February 6, 2018-Internet Initiative Japan Inc. (IIJ, NASDAQ: IIJI, TSE1: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced that it will build its second self-owned data center "Shiroi Data Center Campus". This data center will accommodate medium- to long-term IIJ IT facility that are expected to vastly grow due to the increase in digital data from cloud computing service and the full-fledged spread of IoT technology.

IIJ provides a wide range of services mainly in the networking, cloud, and security sectors. Its increasing number of servers are handling a growing volume of digital data, and it predicts that many more facilities and servers will be required as IoT continues its solid penetration into the market.
Shiroi Data Center Campus will be constructed in Shiroi-city, Chiba Prefecture, Japan and it is scheduled to begin operations in spring of 2019. With its capacity to receive up to 50 MW of electricity on the site are of approximately 40,000 m2, this data center campus can accommodate up to 6,000 racks. IIJ will expand this data center facility on a needs basis by adopting a system module-based (*1) construction method which allows for flexible expansion and short-term construction with low cost.
IIJ will build and operate a reliable, flexible, efficient data center with combining its knowledge of power efficient and facility operation technology together with its operational experiences. IIJ currently operates 21 data center throughout Japan including its' Matsue Data Center Park which was opened in April 2011 as Japan's first container module-based commercial data center using outside-air cooling system.

Features of Shiroi Data Center Campus

Reduced construction time and building costs and ensured flexible scalability due to the adoption of the system module-based construction method
Standardizing the shapes and layouts of component steel frames and outer walls, which form the constituent elements of the building, allows for a high-quality structure to be built quickly and expanded with flexibility in line with actual demand while lowering construction costs.
Realize Energy savings using outside-air cooling
With outside-air cooling technology and AI for cooling and energy control, Shiroi Data Center Campus aims for PUE (*2) of less than 1.2.
Improved facility capacity with AI control and automated data center operations with robotics technology
By cooperating with several equipment manufacturers to provide AI control of operational data for air cooling and electrical facility, servers and other equipment, IIJ plans to improve energy savings and fault detection capabilities of the entire data center. Moreover, the firm will actively endeavor to automate operations, accounting for the potential of using robotics technology in reception, patrolling, monitoring, and other operational tasks.
  • (*1)This method adopts system architecture construction methods that systematize the overall building production by standardizing the components used in the building's construction. It also offers shorter construction times, cost savings, and flexible scalability, while maintaining quality suitable for structures with large, pillarless open spaces.
  • (*2)Power Usage Effectiveness. As an index that shows the energy use efficiency of data centers, the smaller the figure, the lower the percentage of power consumed by equipment other than IT devices.
