Abstract—Data movement within high performance environments can be a large bottleneck to the overall performance of programs. With the addition of continuous storage and usage of...
This paper investigates randomization and replication as strategies to achieve reliable performance in disk arrays targeted for video-on-demand (VoD) workloads. A disk array can p...
Electric energy consumed in data centers is rapidly growing. Power-aware IT, recently called `green IT', is widely recognized as a significant challenge. Disk storage is a no...
We evaluate the reliability of storage system schemes consisting of an equal numbers of data disks and parity disks where each parity disk contains the exclusive or (XOR) of two o...
Declustering and replication are well known techniques used to improve response time of queries in parallel disk environments. As data replication incurs a penalty for updates, da...
