摘要
大数据时代的到来,使得对云存储产生了强烈的需求。云存储性能评测一直是云存储系统研究的热点与难点。通过分析典型云存储平台数据访问的过程,建立云存储数据读写的模型,利用网络分析工具iptools获得云存储系统在处理用户访问请求的各个阶段的时间开销,从中排除网络干扰,反映真正云存储系统数据读写性能。实验结果表明,这种云存储系统数据读写模型是科学合理的,按照模型设计的云存储系统性能评测方法能够有效排除网络干扰,获取反映云存储系统真正读写性能的数据。
After the coming of Big Data Time,the demands for cloud storage are becoming stronger.Performance evaluation of cloud storage is always the key and difficult point of research of cloud storage system.Through analyzing the data access process of typical cloud storage platforms,the data access model of cloud storage was built.With the help of iptools capturing IP packages,the time cost of each phase of processing users＇ access was gained.The true performance can be observed when ignoring the network interference.The test results show that the model is scientific and the test method can gain the true performance of cloud storage system effectively.
