Dynamic Stripe Management Mechanism in Distributed File Systems

Abstract : This paper presents a novel mechanism to dynamically re-size and re-distribute stripes on the storage servers in distributed file systems. To put this mechanism to work, the information about logical I/O access on the client side is piggybacked to physical I/O access on the storage server side, for building the relationship between the logical I/O access and physical I/O access. Moreover, this newly presented mechanism supports varying size of stripes on the storage servers to obtain finer concurrency granularity on accessing to data stripes. As a result, the mapping relationship can be utilized to direct stripe re-sizing and re-distributing on the storage servers dynamically for better system performance. Experimental results show that this stripe management mechanism can reduce I/O response time and boost I/O data throughput significantly for applications with complicated access patterns.
