Abstract EN
Modern storage environment is commonly composed of heterogeneous storage devices.
However, traditional cache algorithms exhibit performance degradation in heterogeneous storage systems because they were not designed to work with the diverse performance characteristics.
In this paper, we present a new cache algorithm called HCM for heterogeneous storage systems.
The HCM algorithm partitions the cache among the disks and adopts an effective scheme to balance the work across the disks.
Furthermore, it applies benefit-cost analysis to choose the best allocation of cache block to improve the performance.
Conducting simulations with a variety of traces and a wide range of cache size, our experiments show that HCM significantly outperforms the existing state-of-the-art storage-aware cache algorithms.
