Testing of Equipment Management IoT Platform Commences- Japan’s First Initiative to Enhance Energy Efficiency of Data Center Equipment

TOKAI Holdings Corporation announced today that its wholly-owned subsidiary, TOKAI Communications
Corporation (hereinafter “TOKAI COM”), began testing an equipment management system at its data center(see attachment). Employing an IoT*1 platform, the system is designed to boost the energy efficiency of datacenter equipment and streamline equipment management.
In 2016 TOKAI COM’s data centers were certified as Eco-Friendly Data Centers*2 used for the Tokyo
Metropolitan Government’s initiative to help businesses to adopt cloud computing. These data centers havebeen recognized for their superior efficiency, energy-saving design, and outstanding operation. TOKAI COM
aims to establish more efficient data center operation through the testing. It will work to help customers saveenergy while doing its share to save the environment.

*1 IoT stands for the Internet of Things. It is a system of sensors, devices, and other objects, connected to the cloud orservers via the Internet, that control one another through the exchange of data.
*2 A designation by the Tokyo Metropolitan Government’s Bureau of Environment certifying and promoting data
centers that are making efforts to reduce their environmental footprint. The certification program and period ended
on March 31, 2017.

Testing of Equipment Management IoT Platform Commences via Joint Initiativeof 4 Corporations- IoT-based Initiative to Enhance Energy Efficiency ofShizuoka Data Center Equipment Using Equipment Data
TOKAI Communications Corporation (headquartered in Aoi-ku, Shizuoka City, Shizuoka; headed byKatsuhiko Tokita, President & CEO; hereinafter “TOKAI COM”) has started testing an equipment
management system that employs an IoT*1 platform at its Shizuoka Data Center. Aimed at enhancing theenergy efficiency of equipment and streamlining equipment management, the testing is being conductedjointly with SightLine Systems Japan K.K. (headquartered in Minato-ku, Tokyo; headed by Yusuke
Nakagawa, President), NTT Facilities, Inc. (headquartered in Minato-ku, Tokyo; headed by Atsushi Ichihoshi,President & CEO), and Takebishi Corporation (headquartered in Ukyo-ku, Kyoto; headed by Isamu Ogura,President).
The testing is designed to visualize the operation of equipment used at the Shizuoka Data Center bycollecting and accumulating data from that equipment on everything from the amount of electric power
consumed by servers and air conditioning systems to ambient temperature, humidity, door opening andclosing events, and meteorological data. It is also aimed at streamlining data center operations throughcorrelation analyses and forecasts.
The roles played by the companies involved in the testing are as noted below.

NTT Facilities, Inc.
Takebishi Corporation• Provision of an IoT platform: Building a platform on CloudPlatform VM*2
• Implementation work: Such as data collection settings• Provision of SightLine EDM*3: Accumulating and analyzing collected data
• Implementation support: Consulting on implementation• System architecture and support in providing air conditioning system operation status,indoor temperature, and other data from TOKAI COM’s data center• Provision of DeviceXPlorer OPC Server*4: Obtaining data from air conditioningsystems• Implementation support: Data collection support

Testing objectives(1) Enhancing maintenance efficiency and productivity of data center equipment•
Cut utility costs•
Increase cooling efficiency of individual air conditioning systems•
Visualize factors impeding cooling and identify ways to improve cooling that are not related toair conditioning systems•
Verify the efficacy of anomaly detection in air conditioning systems(2) Management•
Manage operation based on the plans and actual operation of air conditioning systems•
Manage air conditioning systems using a service level and automatize management•
Manage air conditioning systems based on a capacity forecast and automatize management

••Centralize monitoring of multiple sites and vendors
Analyze the causal relationship between temperature and system performance(3) New discoveries•
Verify whether collecting and analyzing various types of data will deliver new insights
