首发时间:2009-04-23
摘要:磁盘阵列作为存储系统中的关键设备,在线扩容是其一项必不可少的功能,在线扩容是指在不影响用户正常使用的情况下,添加新的磁盘到系统中,达到扩充阵列容量并提高阵列并行度的目标。本文介绍了在线扩容的相关理论和技术,并且在Linux2.6.18内核进行模拟仿真实验实现了RAID6的在线扩容。

Research on online expansion of RAID6
Abstract:RAID is the base device for storage systems and online capacity expansion is an essential function of it. Online capacity expansion function can add additional disks into RAID without suspending normal requests.In this paper,we introduce the theory and technology of online capacity expansion and then realize the online expansion of RAID6 in simulation experiment of linux2.6.18 .
Keywords: Disk Array Online Capacity Expansion RAID6 iSCSI
