Abstract: With the rapid development of storage technology,the storage system is more and more complicated,especially in the distributed environment.How to evaluate all kinds of storage system becomes a big problem.The I/O trace based evaluation method is more objective and accurate for its application.This paper designs and implements an I/O trace based evaluation tool called Distributed I/O Trace Replay System.This system can simultaneously control each node’s I/O trace replaying behavior through the centrized console,and evaluate the I/O performances of each node in the distributed system.This paper describes the design considerations and the implementation details.

Key words: trace replay, distributed, storage system
