NEC Develops Educational Computer System for Kyoto University - 60% reduction in power consumption achieved -
Academic Center for Computing and Media Studies*** For immediate use April 24, 2012
Tokyo, April 24, 2012 - NEC Corporation (NEC; TSE: 6701) recently announced the completion of an educational computer system for Kyoto University (President: Hiroshi Matsumoto) that began operating in March 2012.
The new computer system is an information processing facility for use by students and teaching staff in the university's classrooms for educational and research purposes. Kyoto University has updated the approximately 1,400 terminals in its computer classrooms with a thin client system and introduced virtual desktop services that permit the remote use of the system.
The new system requires only half the number of core servers and features compact, low power consumption workstations. This permits a 60% reduction in power consumption compared with the previous system, resulting in an energy-saving environment. The system is also user-friendly for the increasing number of overseas students. It utilizes a multilingual operating system, which permits the use of a desktop environment and Microsoft Office applications in each user's language.
Key features of the educational computer system are as follows:
- 60% reduction in power consumption
For the core servers, the new educational system uses the Express5800/ECO CENTER, a space-saving server that incorporates superior power-saving technologies. The number of servers has been reduced by half thanks to virtualization. Computer classrooms feature compact Express5800/51Mb-S workstations, which limit power consumption to approximately 25W at boot-up. The result is a 60% reduction in power consumption, which contributes to environmental protection and power conservation. In addition, a power controller is installed in each classroom, allowing the system administrator to control the power supply for all terminals via LAN. This enables a reduction in standby electricity consumption of approximately 4W for each terminal, thereby saving power consumption during idle times. - Multiple languages capability
The educational computer system uses multilingual OS and Microsoft Office applications. Login screens automatically appear in each user's language, which is previously registered in the user management information. It also allows the users to select a language at the time of login. These user-friendly services are intended to assist the increasing number of overseas students. - Remote access on campus and off campus
The system uses virtual desktop services (virtual PC) that allow remote use both on and off campus, which permits off-campus PCs and tablet terminals to use the thin client environment of the computer classrooms. This is done using the integrated control of the Citrix Xen Desktop. This improves convenience by permitting the teaching staff to create lecture materials wherever they are. It also includes a system that manages applications for permission to use virtual PCs. This system automates the entire process from application to permission and registration, thereby allowing appropriate user management. - Easier terminal management
The educational computer system uses only six administrative servers for the thin client system. It utilizes a system that permits easy updates and copying of the boot images by placing these images on centralized storage for sharing with the six servers.
In addition, the terminal features NEC's server operations management technologies. This enables remote monitoring of high loads and abnormal temperatures for terminal CPUs and memory as well as the remote updating of the BIOS for all the terminals. Moreover, the optimized terminal management tool provides a series of functions required for managing terminals at a university, such as those that permit the administrator to control the power supply to terminals, to schedule notification messages and to obtain detailed logs.
These measures have significantly reduced the burden for the operational management of terminals that are spread across the campus.
NEC's introduction of a campus network and a general-purpose computer system supports the improvement of Kyoto University's education and research environment. Going forward, NEC will continue contributing to the introduction of ICT to the education and research fields in an environmentally friendly manner that capitalizes on its experience in developing educational computer systems.
