SGER: Designs for High-Performance Fault-Tolerant Disk Arrays

这是一个计划奖，用于调查RAID系统的系统和软件方面，其中系统开发可以从理论研究中受益。目标是制定研究问题，将理论和系统努力结合起来，影响下一代RAID系统的设计和性能。重点将集中在四个方面：容忍多个错误的数据布局；磁盘阵列的联机可扩展性，其中新磁盘被添加到一个正在运行的系统；有效地实现数据布局映射；以及系统级优化（如大型读写优化）的效果。与实验RAID组（如卡内基梅隆大学、加州大学圣地亚哥分校和IBM阿尔马登）的合作将继续进行，以获得新的研究主题和新的指标。

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.
