This is a planning award to investigate systems and software aspects of RAID systems in which system development can benefit from theoretical research. The goal is to formulate research problems that combine theory and systems efforts to affect the design and performance of the next generation of RAID systems. The focus will be in four areas: data layouts that tolerate multiple faults; on-line extendibility of disk arrays, in which new disks are added to a running system; efficient implementation of data-layout mappings; and the effect of system-level optimizations such as large read and write optimizations. Collaborations with experimental RAID groups (such as Carnegie-Mellon University, UCSD, and IBM Almaden) will be pursued, with the goal of obtaining new research topics and new metrics.

这是一个规划奖，旨在研究系统开发可以从理论研究中受益的RAID系统的系统和软件方面。其目标是制定将理论和系统工作结合在一起的研究问题，以影响下一代RAID系统的设计和性能。重点将放在四个方面：容忍多个故障的数据布局；磁盘阵列的在线可扩展性，即将新磁盘添加到运行中的系统；数据布局映射的有效实施；以及系统级优化的效果，如大型读写优化。将继续与实验性的突击小组(如卡内基-梅隆大学、加州大学洛杉矶分校和IBM Almaden)合作，目标是获得新的研究课题和新的指标。
