【摘要】：基于固態(tài)硬盤的RAID-6陣列,在每次數(shù)據(jù)更新時(shí),都需要計(jì)算和寫入校驗(yàn)信息,降低了陣列的性能和縮短了固態(tài)硬盤的使用壽命,該論文提出了一種基于延遲寫入校驗(yàn)信息策略的RAID-6,稱為PRAID-6.在每次數(shù)據(jù)更新時(shí),PRAID-6只計(jì)算部分校驗(yàn)信息,寫入非易失性存儲(chǔ)器P-Cache.在垃圾回收時(shí),將部分校驗(yàn)信息與原校驗(yàn)信息合并,產(chǎn)生新的校驗(yàn)信息,寫入固態(tài)硬盤.通過(guò)實(shí)驗(yàn)測(cè)試結(jié)果表明PRAID-6的響應(yīng)時(shí)間比RAID-6減少了30%,比RAID-5減少了10%.垃圾回收開銷比RAID-6減少了20%,比RAID-5減少了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，
