The paper puts forward a combined - allocation - scheme based on the idea of constrained - block - allocation at the storing allocation strategy and gives disk - striping about the storing of big capacity disk array . in the study about the access path of the multi - media data , we introduce several kinds of representative multi - dimensions data index structure including k - d tree , r tree , vp tree and so on . ( 3 ) the research of multi - media database system architecture . 在存儲(chǔ)分配策略上根據(jù)受限塊分配( constrainedblock ? allocation )的思想,本文提出了聯(lián)合分配模式( combinedallocationscheme ) ;并針對(duì)大容量磁盤(pán)陣列的存儲(chǔ)給出了條形分配方案( diskstriping ) ;在多媒體數(shù)據(jù)的存取路徑的探討中,重點(diǎn)介紹了幾種有代表性的多維數(shù)據(jù)索引結(jié)構(gòu),有k - d樹(shù)、 r *樹(shù)、 vp樹(shù)等。
The requirement for disk array is coming larger and larger with the development of information popularization in various fields , especially in high - tech industries , financial reorganization and national security department , where the reliable and highly secure disk storage system are required 大規(guī)模的信息存儲(chǔ)技術(shù)方興未艾,隨著我國(guó)個(gè)行業(yè)信息話的發(fā)展對(duì)磁盤(pán)陣列的要求會(huì)越來(lái)越大,特別是高科技產(chǎn)業(yè),金融機(jī)構(gòu)和國(guó)家安全部門(mén)需要高可靠性和高安全性的磁盤(pán)存儲(chǔ)系統(tǒng)。
Ftam supports file operation from different systems , that means ftam has nothing to do with the system on file transfer and file treatment . second : disk array is introduced to tfft . the scsi interface is modified to satisfy the requirement of ewsd Ftam信息模式是基于虛文件和虛文件存儲(chǔ)器的概念,支持不同系統(tǒng)之間的文件操作,即ftam在文件的傳送和處理方面有著與系統(tǒng)無(wú)關(guān)的特性;引進(jìn)磁盤(pán)陣列技術(shù),修改scsi接口,以適應(yīng)ewsd交換機(jī)的要求;參照q3接口協(xié)議編寫(xiě)出上層的網(wǎng)絡(luò)管理軟件系統(tǒng),實(shí)現(xiàn)tmn定義的文件傳送方面的功能。
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(yàn)散布布局考慮了網(wǎng)絡(luò)磁盤(pán)陣列環(huán)境下,本地磁盤(pán)和網(wǎng)絡(luò)磁盤(pán)訪問(wèn)速度上的差異,提高了網(wǎng)絡(luò)磁盤(pán)陣列系統(tǒng)在降級(jí)模式下和重構(gòu)模式下的性能,提高了系統(tǒng)的可靠性。
