Modern storage consists of many optimizations along the data path, from the front-end file system cache and disk layout management to the back-end disk controller cache and on-disk caching. Various components generally exploit the temporal and spatial localities of a workload to improve performance. However, how localities of a workload are transformed by(More)
Temporal and spatial localities are basic concepts in operating systems, and storage systems rely on localities to perform well. Surprisingly, it is difficult to quantify the localities present in workloads and how localities are transformed by storage data path components in metrics that can be compared under diverse settings. In this paper, we introduce(More)
