Fujitsu promotes the construction of environmentally conscious datacenters, and aims to help realize low-carbon, sustainable societies by contributing to greater productivity for customers, and lowering the burden on the environment.
Fujitsu's environmentally conscious datacenters, which have as their top priority the provision of high-quality service to customers, are characterized not only by their energy efficiency but also by their emphasis on reliability and safety. In addition, by visually communicating energy usage, they enable continuous PDCA cycles for identifying issues, taking action, and checking results, and make clear the environmental contribution effects of using a Fujitsu datacenter.
Fujitsu has identified seven categories of technical aspects that merit consideration when constructing an environmentally conscious datacenter. The Fujitsu Group has accumulated technology and know-how in conformity with this framework and applies it in constructing or refurbishing datacenters inside and outside of Japan.
Concentrating a customer's ICT assets in a datacenter also contributes as an energy-saving benefit for society as a whole. By actively being involved in working group activities in the various industry organizations related to datacenters, Fujitsu helps to enhance the value of datacenters to society. Citing one example, in particular, Fujitsu is leading efforts to devise and promote the use of PUE (Power Usage Effectiveness) measurement and calculation methods as an industry representative to the Japan Data Center Council (JDCC).
Fujitsu has won approval from the Ministry of Economy, Trade and Industry's J-Credit Scheme (for reduction of CO2 emissions in Japan) for a method for calculating CO2 reductions achieved by switching to a Fujitsu datacenter and for a scheme that will actually issue credits. This makes it possible to visualize a customer's environmental contribution from outsourcing datacenter services to Fujitsu and to credit the customer for that contribution.
Fujitsu datacenter solutions won the 2013 Datacenter Management and Automation Award sponsored by Germany's Club Gala. This prize is presented to the datacenter implementation with high energy efficiency and the most outstanding environmental performance.
Fujitsu's datacenter solutions are provided to customers as cloud-based ITMaaS (IT Management as a Service). In providing these solutions, we identify inefficient energy usage at customer datacenters, recommend actions for reducing operating costs and improving energy efficiency, and offer customers cost and energy savings through the automation of their datacenter operations.
The Fujitsu Group has datacenters in over 100 locations across the globe and is vigorously moving forward with the introduction of technologies and facilities that are good for the environment.
The Fujitsu South China Datacenter is the first datacenter established and owned by the Fujitsu Group in China. Based on the latest technology, this datacenter offers quality equal to the world's highest standards and is equipped with state-of-the-art technologies for energy efficiency. Equipped with an efficient power plant featuring a rotary UPS (Uninterruptible Power Supply), an energy management system that monitors temperature and individual server rack electricity consumption 24/7, an air-conditioning system with geothermal features, a lighting control system, and other energy efficiency innovations, we have done everything practicable to minimize this datacenter's electricity consumption.
In establishing the Yokohama Datacenter, we not only equipped it with all of the latest energy-efficient facilities and energy-efficiency management systems; we also used a design that uses server room waste heat to warm office space, uses rainwater to flush toilets, and took other proactive steps as well to help realize a recycling-based society. In recognizing the value of our efforts, the City of Yokohama's Comprehensive Assessment System for Building Environment Efficiency (CASBEE) awarded the Yokohama Datacenter its highest, S, rank. In FY 2012, it also won the Kanagawa Prefecture's 2nd Kanagawa Global Warming Prevention Award in the greenhouse gas reduction performance category.
At the London North Datacenter, in the U.K., we have deployed energy use simulation technology designed to optimize datacenter facility and ICT equipment operations. We have also installed free cooling, high-efficiency UPS, and other technologies to cut facility-related CO2 emissions by about 3,000 tons per year, compared to a conventional datacenter.
For our Homebush Datacenter, in Australia, we employed a cooling system that combines the reuse of cooling water and a layout optimized for heat flow, and achieved an 80% reduction in water usage and up to a 32% reduction in energy usage, compared to conventional systems. In addition, we reduced energy consumption by up to 60% through the use of centralized equipment controls and sensor-equipped lighting.
At our Sunnyvale Datacenter in the U.S., we have taken energy-saving steps like installing an on-site power generation facility that uses hydrogen fuel cells and biofuels.
At the FeDC in Singapore, we have installed a high-efficiency power plant, temperature monitoring system, lighting control system, and other technology to make this facility energy efficient.
With the rapid adoption of ICT and cloud computing in particular, the datacenters that underlie it all are taking on even greater importance. As a new form of datacenter, Fujitsu began in October 2012 to provide "container" datacenters that can be constructed in a short time and used to start operations at a small scale. Because they are relatively small and can be cooled without waste, container datacenters operate with only a small amount of electric power and have low operating costs.
Our container datacenters employ indirect air cooling that takes external air into a heat exchanger and expels air warmed by the ICT equipment. The use of external air reduces the amount of energy needed for air conditioning and eliminates the need to install the external water-cooling equipment required for a water-cooled system. A key characteristic of our container datacenters, therefore, is that they can be installed in any environment or location. In addition, because external air is not taken into the container directly, the system is one that does not require adjustments of humidity and is not subject to the effects of dust or insects.
The ICT equipment and facilities installed in the container are controlled by Fujitsu's own operating and management software. And electricity consumption is minimized through the deployment of electrical system control technology developed by Fujitsu Laboratories Ltd.
