A new approach in the analysis and modeling of disk access patterns

While in previous work we have demonstrated that disk arrival patterns are consistent with self-similarity and have provided a physical explanation for the self-similar phenomenon in disk arrival patterns, the authors now deal with the analysis and modeling of disk access patterns. We provide visual and mathematical evidence showing that the same bursty behavior observed in the time series can also be observed in the spatial series formed by the starting address of the accessed blocks. Moreover, we demonstrate that the clustering of accesses in areas of the disk has self-similar characteristics. Next, we demonstrate that the observed behavior can be explained using the same self-similar property used in the analysis of arrival patterns and applying the same physical explanation.
