摘要： 为提高磁盘阵列的可靠性,该文提出采用扩展海明码构造阵列的存储数据,形成一种可靠磁盘阵列——RAID7.充分利用磁盘的ECC检错指示和扩展海明码的纠1检2能力实现RAID7的容错功能,可有效地提高磁盘阵列的数据有效性和系统可靠性。

关键词: 扩展海明码, 磁盘阵列, 计算机I/0瓶颈, 冗余结构

Abstract: The disk array techniqne is an efficient way to break the I/0 bottleneck of the computer system,and is widely studied and developed recently in the world.In order to increase the reliability of the disk array, this paper proposes a new kind of disk array-RAID7 (Redundant Array of Inexpensive Disks level seve),in which the data store unit of the array is coded using the extended Hamming code.It gives high data availability and high system reliability.

Key words: extended hamming code, computer I/0 bottleneck, redundant structure, disk array
