OVERVIEW: Hitachi is working on research and development aimed at implementing KaaS that extract and present valuable information (knowledge) from the large volumes of data generated by social infrastructure such as industry, transport, and electricity supply. Two issues associated with realizing this goal are getting access to extensive computing capacity and ensuring the privacy of the data. To solve these problems, Hitachi is developing an architecture that can run various different analysis algorithms on large distributed processing platforms and, in addition to the ability to increase capacity simply by adding computing resources, has also developed privacy protection systems that incorporate two features: data access control for multiple items with multiple IDs and k-anonymization. The resulting technology is currently being used for applications such as maintenance and diagnostic services and location-aware services where it is the subject of ongoing evaluation and improvement. The aim for the future is to provide knowledge platforms that merge information in a way that transcends boundaries between industries by building systems with a high level of computing performance able to analyze data from across different industries.

OVERVIEW: Data centers house IT equipment centrally and run diverse IT services that form part of our social infrastructure, and factors such as their growing size and the increasing density of installed IT equipment have made the associated increase in power consumption a matter of concern around the world. It is believed that the solution to this problem can be found not only in reducing the power consumption of individual equipment but also through the coordinated control of all the equipment in the data center. Hitachi develops a range of different equipment and systems for data centers and in 2007 embarked on an "Environmentally Conscious Data Center Project" that draws on the overall capabilities of the Hitachi Group and an "IT Power-saving Plan" for reducing the power consumption of IT equipment. The major outcomes of this work to date have included the commercialization of a power supply unit for IT equipment and a spot cooling system that features natural circulation of the refrigerant. Future initiatives will include technology for collaborative control of IT and facilities which fits in with the overall aim of implementing center-wide control.
