Development of Top-Level Energy Efficient Products
As ICT spreads, an increase in energy demand is expected in proportion to the higher performance and higher-density integration of servers and other ICT products. Accompanying this, energy-related regulations for ICT products are increasing in various countries and regions, such that energy efficiency is taking on importance within society in the form of energy label conformance and green procurement requirements.
The Fujitsu Group believes that we also must aim to improve the energy performance of products during their use, in order to reduce GHG emissions. In that context, we will actively implement energy-saving technologies and continue working to improve the energy efficiency of products. Through these and other product-development efforts, we will strive to reduce the power consumption of our offerings in customer usage settings.
FY 2017 Performance and Results
Actively Applied Energy-Saving Technology
We have set targets for the achievement of top-level energy efficiency based on the number of product series that are expected to be developed during FY 2016-18.
Applications of energy-saving technologies include new, high-efficiency microprocessors and power supplies, energy-saving displays, optimized energy-saving controls, and the strengthening of power management features. In addition to these, we are actively undertaking the aggregation of LSIs and the reduction of components.
Achieved Top-Level Energy Efficiency for 68.3% of New Products
As a result of applying and expanding energy-saving technologies across our divisions in products including servers, PCs, network devices, and imaging devices, we were able to exceed by over 68.3% our 45% target (vs. FY 2017) for new product top-level energy efficiency.
Working toward Our Targets
To help "achieve top-level energy efficiency for 50% or more of the new products," one of the objectives in our Environmental Action Plan, we will continue to make even stronger development efforts to give our products - from leading items in each division to the rest of the lineup - top-level energy efficiency. In addition, we will deploy outstanding energy-saving technology and expand its application to products. Looking toward the future, we aim to push the development of advanced technology, which will contribute to revolutionary improvements in energy efficiency.

Main Activities in FY 2017
ETERNUS DX series: Hybrid storage system for low power consumption
The ETERNUS DX series is a hybrid storage system that is equipped with a variety of technology and achieves low power consumption. The DX series can be equipped with a maximum of 4,608 disk drives. Also, the DX series is equipped with an eco mode function which utilizes MAID technology*1 for rotating the disks only when necessary. The eco mode function stops the supply of power to disks when the disk drive is not accessed for a certain period of time. Power consumption is reduced by a maximum of approximately 20%, while CO2 emissions are reduced by approximately 3,000 kg*2 annually.
Other technologies used by the ETERNUS DX series for reducing power consumption are an industry-leading high-efficiency power supply unit and multi-level control of cooling fans rotation depending on the room temperature conditions. Furthermore, ETERNUS DX was one of the earliest systems to implement 12TB disks, 15TB SSD, and other of the latest high-capacity drives, thus achieving reduction of product installation area and improving energy efficiency.
*1 MAID technology: MAID is an acronym for Massive Array of Idle Disks. By stopping disk drives with a low usage frequency, this technology reduces power consumption and extends the lifespan of disk drives.
*2 Comparison conducted by our company between 1) an ETERNUS DX500 S4 that is constantly operated using 130 300GB disks and 80 1TB disks, and 2) when stopping power supply for 20 hours per day for the 1TB disks only.
FRAM enables low power consumption even in high-temperature environments
In order to achieve Society 5.0 (ultra-smart society), the Internet of Things (IoT) which connects people and physical devices is essential. However, one issue with IoT is striving to increase the efficiency of energy usage. Of course, the current digital society demands lower power consumption for semiconductor LSIs that fulfill an important role in the achievement of IoT. There is also increased demand for nonvolatile memory in which data is not lost even when power is turned off. Also, generally speaking, power consumption increases when LSIs are operated in a high-temperature environment. Therefore, optimal electronic parts are required particularly for products which are equipped with motor devices that generate heat.
In order to respond to these needs, Fujitsu Semiconductor Limited developed FRAM MB85RS256TY and MB85RS128TY to enable suppression of power consumption even in a high-temperature environment. FRAM is nonvolatile memory that possesses the features of “faster write speeds” and “greater read/write cycle endurance.” In addition to developing new elements such as ferroelectrics and transistors which compose FRAM, Fujitsu Semiconductor conducted review spanning from specifications to detailed circuit design. As a result, the company succeeded in decreasing power consumption by approximately 60% while expanding the maximum operating temperature by 40℃ compared to conventional products. The products developed by Fujitsu Semiconductor Limited can be operated at 125℃. These products are expected to be used in a wide range of industries including automotive equipment and industrial robots.

FUJITSU Retail Solution TeamCAT/mini V3: Lightweight design and reduced power consumption
TeamCAT/mini V3 is a multidevice for shopping center tenants. The extensive ports for connection to peripheral devices make it possible to generate shopping center sales reports, use various payment services, and perform point management tasks from a single device. TeamCAT/mini V3 also features a compact body and can be installed in any location. Application development is also made easy by employing the latest multipurpose OS (Windows10 IoT Enterprise 2016 LTSB (64bit)) for the application software.
TeamCAT/mini V3 uses the Intel Atom x5-z8550 (4 core) for the CPU. This made it possible to reduce power consumption by about 30% when compared to conventional products (similar processing), even while being equipped with extensive external interfaces and high-capacity memory. For the lightweight design, the thickness of the PCB has been reduced to two-thirds of conventional products and the number of components has been reduced by utilizing the high-performance CPU. Moreover, conventional products are equipped with balancers to achieve balance with torque occurring when opening the thermal printer cover. In contrast, TeamCAT/mini V3 does not use a balancer; instead, it has a torque damper for reducing torque. These changes achieved a weight reduction of about 17% compared to conventional products.
