摘要
针对iSCSI在磁盘I/O和网络传输速度上存在的瓶颈问题,提出了一种改进的iSCSI存储架构。根据请求包大小动态的选择存储策略,目标端采用提出的并行算法对包进行处理,并且消除了写冗余并减少了对同一扇区多次读操作的冗余。实验结果表明,该策略有效地缩短了系统的响应时间,提高了系统的吞吐量,从而达到优化iSCSI存储系统性能的目的。
Aimed at the problems of the iSCSI bottleneck between the I/O of disk and the network speed,the improved iSCSI storage architecture is presented.This strategy can dynamic select storage strategy according to the size of request packets and eliminate the redundant overwrites.Thus the latency caused by multiple reads to same storage sector are reduced in the parallel algorithm of target.The experiment shows that the strategy has shorter response time and higher throughput to improve the iSCSI performance.
