摘要

提出了一种新的RAID-x (x级廉价磁盘冗余阵列)体系结构，用于在无服务器计算机集群上进行分布式I/O处理。RAID-x架构基于跨集群中所有分布式磁盘的正交条带和镜像(OSM)的新概念。这种OSM方法的主要优点在于:(1)显著提高并行I/O带宽;(2)在后台隐藏磁盘镜像开销;(3)大大提高了集群计算应用的可扩展性和可靠性。所有声称的优势都与1999年在USC构建的木马集群上的基准性能结果相证实。作者讨论了在无服务器集群环境中分布式RAID-x的可伸缩I/O性能、增强的系统可靠性和条纹检查点等问题。

RAID-x: a new distributed disk array for I/O-centric cluster computing

A new RAID-x (redundant array of inexpensive disks at level x) architecture is presented for distributed I/O processing on a serverless cluster of computers. The RAID-x architecture is based on a new concept of orthogonal striping and mirroring (OSM) across all distributed disks in the cluster. The primary advantages of this OSM approach lie in: (1) a significant improvement in parallel I/O bandwidth; (2) hiding disk mirroring overhead in the background; and (3) greatly enhanced scalability and reliability in cluster computing applications. All claimed advantages are substantiated with benchmark performance results on the Trojans cluster built at USC in 1999. The authors discuss the issues of scalable I/O performance, enhanced system reliability, and striped checkpointing on distributed RAID-x in a serverless cluster environment.
