Abstract

Storage systems represent a growing market. In recent years there has been an explosion of applications that use enormous amounts of data. Disk arrays are today´s standard solution for enterprise class storage systems. One of the most crucial parameters in designing a disk array is the size of the striping unit. The paper presents and validates a performance model for RAID level 5. The model is created as a closed fork-join queue network (CFJQN) under synchronous I/O workloads. It can be used to compute the optimal strip unit size for disk arrays
