- 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
”是一個磁盤文件系統(tǒng)，在該系統(tǒng)上，數(shù)據(jù)分為若干個塊，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：由一組兩個或者多個磁盤組成，就系統(tǒng)而言可以看作是一個大的邏輯磁盤。一個磁盤陣列不僅可以當(dāng)一個軟件裝置，也可以當(dāng)作一個硬件裝置。 - 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)計并實現(xiàn)了用于存儲磁盤陣列信息的內(nèi)部數(shù)據(jù)結(jié)構(gòu)，通過對命令的合法性檢查，為用戶提供了一個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 （簡稱rs碼）是一種具有很強的糾正突發(fā)和隨機錯誤的信道編碼方式，在深空通信、移動通信、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。 - 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 ( dvb ) , and so on
Reed - solomon碼(簡稱rs碼)是一種具有很強糾正突發(fā)和隨機錯誤能力的信道編碼方式,在深空通信、移動通信、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)，即在多個磁盤上交叉存儲使得多盤可平行操作， i o響應(yīng)時間得到了改善，同時利用冗余容錯技術(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)入控制等問題進行了分析，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)計中采用了服務(wù)器集群與存儲區(qū)域網(wǎng)絡(luò)( san )相結(jié)合的系統(tǒng)設(shè)計，采用microsoftwindows2000advanceserver操作系統(tǒng)，利用網(wǎng)絡(luò)負(fù)載平衡技術(shù)( nlb )實現(xiàn)服務(wù)器集群內(nèi)各節(jié)點的負(fù)載均衡，采用粗粒度數(shù)據(jù)條紋化對磁盤陣列上存儲的流媒體數(shù)據(jù)進行布局，并使用windowsmedia技術(shù)實現(xiàn)流媒體應(yīng)用。
