便宜磁盘(袭击) 的冗余的数组 10 作为最可靠的磁盘数组建筑学被知道在在数据损失给静止结果的一样的镜子容忍直到二个磁盘的全部的磁盘失败,而是失败的一半。在这篇论文,我们建议新磁盘数组体系结构,反射并且同等值保护了袭击(MP 袭击) ,它联合反射并且进一步改进磁盘数组的可靠性的同等值技术。在 MP 袭击后面的主要想法是由反射和同等值技术保护数据:把数据的二个拷贝放在在一样的同等值组以内在木头磁盘给并且更新同等值块的一样的镜子。可靠性分析证明以数据损失(MTTDL ) 的吝啬的时间, MP 袭击的可靠性比 RAID10 和 RAID5 好一些。
Redundant array of inexpensive disk (RAID)10 is known as the most reliable disk array architecture to tolerate up to half of total disk failures, but failure of two disks in the same mirror set still results in data loss. In this paper, we propose a new disk array architecture, mirroring and parity protected RAID (MP-RAID), which combines both mirroring and parity techniques to further improve reliability of disk arrays. The main idea behind MP-RAID is to protect the data by both mirroring and parity techniques: keep two copies of data in the same mirror set and update the parity block in the log disk within the same parity groups. Reliability analysis shows that the reliability of MP-RAID, in terms of mean time to data loss (MTTDL), is much better than RAID10 and RAID5.
