Abstract:The fault-tolerant ability of an object-based storage system is an important factor that affects the reliability and usability of the entire system. Existing fault-tolerant methods either increase procurement cost, or impede performance. In this paper, we propose an I/O fault-tolerant method based on an application-level agent, which can perform fault-tolerance swiftly and efficiently at runtime by constructing the fault-tolerant agent’s execution engine. We consider a “disk full” exception as an example to fu… Show more
