Researches on technologies about testing IOPS and data transfer speed of disk arrays in mass storage systems. We propose a parallel testing technology towards the high performance disk array and realize the testing work on the newest developed disk array. By taking researches on many factors which effect disk performance seriously and quantifying them through experiments, so we realize evaluations...
For parallel disk array systems, the parallelism among disks is the key factor influencing the performance and the scale of systems. Unfortunately, the parallelism of cached blocks is largely ignored by cache management schemes that focus on reducing the number of cache misses. Therefore, the performance of parallel disks array systems for workloads with a skew access pattern can be seriously degraded...
