To meet diversifying collocation needs including rapidly growing AI demand
At the same time, will accelerate initiatives toward carbon neutral data centers

Internet Initiative Japan Inc.
TOKYO - July 3, 2023 - Internet Initiative Japan Inc. (TSE Prime: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced the start of operation this month of the second phase building on the Company's Shiroi Data Center Campus (Shiroi-shi, Chiba Prefecture; "Shiroi DCC"), which had been under construction since May 2022. The Shiroi DCC's second phase building has a site area of approximately 8,000 square meters, maximum incoming power capacity of 10MW (megawatts), and scale of 1,100 racks. Starting the datacenter service with around 50 percent of the 1,100 racks, all remaining racks are expected to be in service by February 2024.
The second phase building, besides expanding the space housing equipment for IIJ services for which demand is growing, is also able to meet increasingly diverse collocation needs, from companies offering private cloud services and SI service providers to cloud vendors and content providers, including those installing AI platforms, as well as data center service providers needing reseller space with outstanding energy efficiency.

The Shiroi DCC is one of the centers concentrating infrastructure equipment for IIJ cloud and network services. As use of IIJ services has increased lately against the background of growing ICT demand, construction was carried out on the second phase building as a facility for expanding service infrastructure equipment. Another recent trend is the provision of hyperscale data centers, having incoming power capacity exceeding several tens of MW. Most of these are intended for use by"mega-cloud service providers," whereas data center facilities for collocation or housing of other kinds of service providers or enterprises have tended to be in short supply. Against this backdrop, the Shiroi DCC's second phase building aims to meet increasingly diverse collocation needs, from companies offering private cloud services and SI service providers to cloud vendors and content providers, including those installing AI platforms, as well as data center service providers needing reseller space with outstanding energy efficiency.
Further, given that plans have been announced for the use in data centers of server CPUs with maximum power use (Thermal Design Power: TDP) exceeding 300W, along with the expected growth in demand for servers equipped with graphics processing units (GPUs), which consume large amounts of electric power and are needed for data processing in the rapidly growing generative AI services, the new server building meets power demand of 10 to 20kW per rack.
An additional factor is the increasingly challenging demands on the data center industry for initiatives in the areas of energy efficiency and renewable energy use. Examples include the new benchmark system introduced in the Act on Rationalizing Energy Use of 2022, calling on the industry to aim for an energy efficiency level of PUE(*) 1.4 or below; the setting of new measures for switching to non-fossil energy in fiscal 2023; and the revision of technical requirements in RE100 encouraging the spread of energy efficiency with high additionality. In the second phase building of the Shiroi DCC, as well, besides bringing together the existing energy-saving technology built up by the IIJ Group to date, carbon neutrality will be aggressively advanced through experimental introduction of new technology and technology development, while supporting decarbonization by customers.
230V 30A as base, with 100V 30A available by request.
Expansion of the Shiroi DCC to a second server building is being done without a large increase in operators, thanks to the automation and systemization of data center operations, including the automated reception system carried over from the first phase building.
Besides the ability to connect directly to various IIJ network service and cloud service equipment, a JPNAP (Japan Network Access Point) site in the Shiroi DCC provides Internet exchange (IX) service, realizing interoperability among content providers and Internet access providers in Japan and overseas. The Inzai district where the Shiroi DCC is located is drawing attention for its concentration of data centers, bringing the advantage also of use as a network hub, for connection to various cloud services and nearby data centers.
IIJ is committed to further expanding infrastructure for meeting the vigorous demand for data center services, while aiming to lead the way in the ICT industry's efforts to advance the cause of carbon neutrality.
