I/O Response Rate Analysis in the Replicate-Based Object Storage System

With the development of storage technology, storage system capacity has been rapidly growing, so rapid that storage I/O performance has become one of the most critical issues in large complex systems. This article combines the latest research in object-based storage with replica technology to share I/O in the object storage system, and to maintain high and stable I/O response rate. Theoretical derivation and simulation experiment results are both examined, which show the prominent role that replicas can play in improving system performance and maintain stable I/O response rate.
