【摘要】：基于固态硬盘的RAID-6阵列,在每次数据更新时,都需要计算和写入校验信息,降低了阵列的性能和缩短了固态硬盘的使用寿命,该论文提出了一种基于延迟写入校验信息策略的RAID-6,称为PRAID-6.在每次数据更新时,PRAID-6只计算部分校验信息,写入非易失性存储器P-Cache.在垃圾回收时,将部分校验信息与原校验信息合并,产生新的校验信息,写入固态硬盘.通过实验测试结果表明PRAID-6的响应时间比RAID-6减少了30%,比RAID-5减少了10%.垃圾回收开销比RAID-6减少了20%,比RAID-5减少了15%.
[Abstract]:Based on the RAID-6 array of solid-state hard disk, the verification information needs to be calculated and written every time the data is updated, which reduces the performance of the array and shortens the service life of solid-state hard disk. In this paper, a RAID-6, based on delayed write check information strategy is called PRAID-6.. Each time the data is updated, PRAID-6 calculates only part of the check information and writes to the non-volatile memory P 鈮，
