A stripe set is a disk file system , on which data is divided into blocks and spread in a fixed order among all disks in a disk array ”是一個(gè)磁盤文件系統(tǒng),在該系統(tǒng)上,數(shù)據(jù)分為若干個(gè)塊,并在磁盤數(shù)組中的所有磁盤上按照固定順序排列。
If it is higher than that , one striping unit needs more than one i o to be issued so that it may de - parallel disk i os in large disk arrays 如果大于該尺寸,一個(gè)分段單元就需要不止一次地發(fā)出i / o ,以便它可以在大型磁盤陣列中近似地并行化磁盤i / o 。
A set of two or more disks that may appear to the system as one large disk . a disk array can be either a software or a hardware device 磁盤陣列:由一組兩個(gè)或者多個(gè)磁盤組成,就系統(tǒng)而言可以看作是一個(gè)大的邏輯磁盤。一個(gè)磁盤陣列不僅可以當(dāng)一個(gè)軟件裝置,也可以當(dāng)作一個(gè)硬件裝置。
Using the disk arrays " infortions stored in the internal data structure implemented by the author and his teammates , commands from users are to be validated . so a more robust logical disk array appears in the user " s view 設(shè)計(jì)并實(shí)現(xiàn)了用于存儲(chǔ)磁盤陣列信息的內(nèi)部數(shù)據(jù)結(jié)構(gòu),通過(guò)對(duì)命令的合法性檢查,為用戶提供了一個(gè)更加健壯的邏輯磁盤陣列。
Redundant disk arrays are a popular method to improve the reliability and performance of disk storage and an ever - increasing number of array architectures and data layouts are being proposed to balance cost , performance , and reliability 冗余磁盤陣列作為一種提高存儲(chǔ)系統(tǒng)可靠性和性能的技術(shù),已經(jīng)得到了廣泛的應(yīng)用。有關(guān)磁盤陣列結(jié)構(gòu)和數(shù)據(jù)布局的研究也一直比較活躍。
Reed - solomon code , a powerful error correcting code for burst and random errors , is widely applied to deep space communications , mobile communications , disk array , digital video broadcasting system , and so on Reed - solomon (簡(jiǎn)稱rs碼)是一種具有很強(qiáng)的糾正突發(fā)和隨機(jī)錯(cuò)誤的信道編碼方式,在深空通信、移動(dòng)通信、磁盤陣列以及數(shù)字視頻廣播( dvb )等系統(tǒng)中具有廣泛的應(yīng)用。

Data cent technology is adopted in raid array , that means the parallel operation in many disks . the i / o respond time is improved , the same time the reliability and security of disk array is highly improved by the technology of redundancy and permitting mistakes Raid陣列由于采用了數(shù)據(jù)分塊技術(shù),即在多個(gè)磁盤上交叉存儲(chǔ)使得多盤可平行操作, i o響應(yīng)時(shí)間得到了改善,同時(shí)利用冗余容錯(cuò)技術(shù),極大的提高了磁盤陣列的可靠性和安全性。
We summarized common video server architecture , analyzed the performance requirements , data placement and admission control problem , etc . , of large - scale video storage server . we propose a new data placement scheme and its admission control algorithm based on parallel disk arrays , which can satisfy user ' s multi - qos requirements 就大規(guī)模視頻服務(wù)器的存儲(chǔ)體系結(jié)構(gòu)、性能指標(biāo)要求、數(shù)據(jù)布局和準(zhǔn)入控制等問(wèn)題進(jìn)行了分析,提出了基于并行磁盤陣列、可滿足用戶多qos要求的、大規(guī)模視頻服務(wù)器存儲(chǔ)體系結(jié)構(gòu)及調(diào)度算法。
In the design , we adopt the microsoft windows 2000 advance server operating system and the system design that combines the server cluster and the san . nlb technology is used to realize the load balance of all the nodes in the server , and the layout of streaming media data preserved on the disk arrays is realized by coarse - grained striping . windows media technology is introduced to help the application of streaming media 在此設(shè)計(jì)中采用了服務(wù)器集群與存儲(chǔ)區(qū)域網(wǎng)絡(luò)( san )相結(jié)合的系統(tǒng)設(shè)計(jì),采用microsoftwindows2000advanceserver操作系統(tǒng),利用網(wǎng)絡(luò)負(fù)載平衡技術(shù)( nlb )實(shí)現(xiàn)服務(wù)器集群內(nèi)各節(jié)點(diǎn)的負(fù)載均衡,采用粗粒度數(shù)據(jù)條紋化對(duì)磁盤陣列上存儲(chǔ)的流媒體數(shù)據(jù)進(jìn)行布局,并使用windowsmedia技術(shù)實(shí)現(xiàn)流媒體應(yīng)用。
