Autonomous decentralized file system and its application

From the standpoint of system construction/expansion, it is required that a computer system is flexible and tolerant for change of the system structure and has software productivity. A computer system is also required to be easily operated by users regardless of its structure and status. In order to achieve these requirements, the EVERUN (EVEr RUNning) computer system has been developed based on the autonomous decentralized system concept. The distributed file system for this EVERUN computer system is proposed. This file system realizes flexible fault-tolerance, and easy expansion, operation and maintenance. The EVERUN computer system including this file system has been applied to production management systems and so on. The effectiveness of this computer system has been verified.<
