摘要： 通过仿真试验对磁盘阵列在并发流媒体负载下的性能进行了定量的研究,对访问请求响应时间的分布进行了统计和分析,得到了磁盘阵列为流媒体应用提供的服务质量随并发流媒体应用数量增加的变化曲线,确定了满足QoS需求的并发流媒体应用数量的阈值。

Abstract: This paper uses the simulation environment to study the performance of the disk arrays with the concurrent stream-media workload,analyzes the statistical distribution of the response time of requests,obtains the curves of the QoS provided by the disk arrays with the increases of the workload,finally finds the certain thresholds of the number of concurrent stream-media applications.
