摘要
通过追踪I/O数据在信道中的传输过程,分析了当前海量存储系统可能存在的瓶颈。指出了在硬件性能一定的情况下,编码技术在磁盘阵列中的应用,以及对存储系统的容错性和存取速度的贡献。本文最后提出了一种存储综合测评系统,具体评估了P4080和IOP80331平台的读写带宽和系统性能。
By tracking the I/O data transmission in the signal channel, analizing the bottlenecks in the mass storage system. Pointed out that in the condition that the hardware performance was certainly, the coding technology application in the disk array, as well as the contribution in the fault tolerance and access speed of the storage system. This article concludes with a comprehensive evaluation of a storage system, specific the read and write bandwidth and system performance of P4080 and IOP80331 platform.
