| 摘 要： | 基于数据存储I/O通道,为“服务器存储”和“数据中心”两种典型存储结构建立排队模型,利用模型对比分析两种结构的性能特点。结果表明:与服务器存储相比,数据中心的“用户绕过服务器直接访问存储设备”结构,避免了服务器成为系统瓶颈,提高了存储设备利用率,使系统总吞吐量有较大幅度增长。实验证明:该模型可有效地反映实际存储系统的性能变化趋势,并给出大致性能评价。

| Abstract: | This article presents a modeling method based on common I/O paths to describe current storage architectures.Queuing network models are presented for server storage systems and Data Centers.Data Centers use an IP-based storage system in which storage devices can be accessed directly by hosts without passing through a server.Simulations and experimental results show that Data Centers provide much higher performance than server storage systems.The I/O path based performance models are also shown to be effective for analyzing and evaluating different storage systems. |
