it improves degraded-and reconstruction-mode performance and reliability greatly . “ string parity declustering data layout ” can tolerate single string ( node ) failure in network raid, the reliability of this data layout is several order of magnitudes better than those of other data layouts 鏈校驗散布布局考慮了磁盤相關(guān)性問題,使網(wǎng)絡磁盤陣列系統(tǒng)具有容許單一共享鏈(節(jié)點)的能力,從而極大地提高了網(wǎng)絡磁盤陣列的可靠性。
this dissertation discusses data layout technology for improving reliability and scalability in network based disk arrays . two parity declustering data layouts for network based disk arrays are proposed in this dissertation . “ weighted parity declustering data layout ” distinguishes local / remote disk access performance when use parity declustering technology in network raid 加權(quán)校驗散布布局考慮了網(wǎng)絡磁盤陣列環(huán)境下,本地磁盤和網(wǎng)絡磁盤訪問速度上的差異,提高了網(wǎng)絡磁盤陣列系統(tǒng)在降級模式下和重構(gòu)模式下的性能,提高了系統(tǒng)的可靠性。
