The authors consider algorithms for integrated prefetching and caching in a model with a fixed-size cache and any number of backing storage devices (disks). Previously, the single disk case was considered by Cao et al. (1995). They show that the natural extension of their aggressive algorithm to the parallel disk case is suboptimal by a factor near the number of disks in the worst case. The main result is a new algorithm, reverse aggressive, with near-optimal performance in the presence of multiple disks
