Environmental Activities in Datacenters

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.

Promoting Environmentally Conscious Datacenters

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.

Framework for Considering Technology for Constructing an Environmentally Conscious Datacenter

  • Visual Representation
    Monitoring electricity consumption, temperature, and humidity to analyze and evaluate energy usage.
  • Power Distribution Innovation (Optimal Energy Usage)
    Our goal is to achieve high reliability and rationality in the distribution of electric power to ICT equipment, and do so from the perspectives of stable operation, business continuity, and energy efficiency. We are also working with suppliers to achieve technological improvements and innovations in battery materials for uninterruptible power supplies (UPS) and in other individual devices and facilities.
  • Ultra-High Efficiency Air Conditioning (Optimal Air Conditioning)
    We work to make air conditioning, which is critical to saving energy, more efficient. Our aim is to achieve air conditioning that relies 100% on external air and is optimized for the climatic and geographic conditions of each datacenter.
  • Green Energy
    We continue to seek ways to use solar power and other renewable forms of energy.
  • Facility Delivery Innovations (Housing Innovations)
    We provide datacenters from the very largest to the very smallest and of various specifications to match customer needs. Working from a modular datacenter concept, rapid delivery of high-quality datacenters matching customer needs is our goal.
  • ICT Platforms
    The ICT equipment for installation in datacenters is constantly evolving. But it is not enough to simply use the latest, most efficient equipment; we search for equipment best suited for use in a datacenter and work with our ICT Equipment Unit to offer datacenters with the best overall efficiency.
  • Energy Procurement Innovation (Energy links between facilities)
    To maintain business continuity, we aim to create datacenters with high energy source independence. We, therefore, seek to ensure a stable supply of power and we consider a variety of energy procurement possibilities, including on-site and nearby facilities.

Initiatives in FY 2012

Contributions to Industry Organizations

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).

Visualization of Effects

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.

Datacenter Solution wins 2013 Datacenter Management and Automation Award in Germany

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.

Example of the Fujitsu Group's Global Environmentally Conscious Datacenters

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.

Indirect Air Cooling Container Datacenters

Container datacenter

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.
