摘要： 在很多实时应用领域，如遥感遥测、雷达数据采集中都需要高速连续数据记录系统。文章针对基于盘阵列结构的记录系统，提出了一种提高其可靠性的方法浮动校验组方法。与传统容错方法相比，浮动校验组方法通过阵列结构的动态改变，可以显著提高盘阵列记录系统的可靠性。

Abstract: In many real-time fields, the sustained high-speed data recording system is required. This paper proposes a high-speed and sustained data recording system based on complex-RAID. Floating Parity Group (FPG) is proposed as a new way to tolerate multiple disk failures in a complex disk array in this paper. Compared with traditional fault-tolerant scheme, FPG can improve the system reliability dramatically by changing the configuration of the disk array.
