【摘要】：隨著計算機網(wǎng)絡(luò)和信息技術(shù)的不斷發(fā)展,人們需要存儲和利用的數(shù)據(jù)呈現(xiàn)出指數(shù)增長。存儲虛擬化技術(shù)可以減少存儲系統(tǒng)的管理復(fù)雜度,使得人們只需去利用虛擬化以后的統(tǒng)一的存儲空間,而不必去考慮物理存儲設(shè)備的細(xì)節(jié),同時可以提高存儲設(shè)備的利用率,節(jié)約存儲設(shè)備的成本。存儲虛擬化技術(shù)近年來引起了人們的廣泛關(guān)注,各國學(xué)者都進行了深入的研究,存儲虛擬化已逐漸成為存儲的發(fā)展方向。iSCSI協(xié)議是基于IP協(xié)議的技術(shù)標(biāo)準(zhǔn),是當(dāng)前人們研究的熱點。本文深入研究了存儲虛擬化技術(shù)和存儲區(qū)域網(wǎng)(SAN)的相關(guān)理論,結(jié)合對iSCSI協(xié)議的研究,提出了一種基于iSCSI的SAN存儲虛擬化的實現(xiàn)方案。所做的主要工作如下： 本文首先研究了存儲虛擬化的原理和概念,對存儲虛擬化的優(yōu)點、分類、實現(xiàn)方式等內(nèi)容進行了闡述,并對帶內(nèi)存儲虛擬化和帶外存儲虛擬化的實現(xiàn)方式進行研究。然后闡述了SAN技術(shù)的原理、內(nèi)容和虛擬化的實現(xiàn)方式。接著研究了SCSI協(xié)議的基本協(xié)議模型以及SCSI命令描述塊,同時重點介紹了iSCSI的相關(guān)理論,對iSCSI協(xié)議的協(xié)議棧、協(xié)議數(shù)據(jù)單元以及協(xié)議的讀寫操作的實現(xiàn)流程進行了研究。 在以上內(nèi)容的基礎(chǔ)上,通過對iSCSI協(xié)議的啟動端和目標(biāo)端的結(jié)構(gòu)、工作流程及其具體實現(xiàn)中的函數(shù)、線程等的分析,完成了iSCSI協(xié)議的啟動端和目標(biāo)端的實現(xiàn)。最后本文提出了一種基于iSCSI的SAN存儲虛擬化的實現(xiàn)方案,并完成了設(shè)計與實現(xiàn),其中重點介紹了存儲虛擬化系統(tǒng)中的用戶邏輯卷管理模塊和存儲虛擬化管理配置模塊的設(shè)計與實現(xiàn)。同時闡述了存儲資源的整合、存儲用戶SCSI請求的數(shù)據(jù)流程、存儲設(shè)備的配置信息和存儲用戶的配置信息。最后通過程序?qū)崿F(xiàn)了這兩個模塊,通過測試證明了本文所提出的方案的可行性,整個系統(tǒng)的設(shè)計和實現(xiàn)的代價比較低,存儲資源的利用率可以得到很大的提高,這樣的解決方案更具有實際的應(yīng)用價值。
[Abstract]:With the development of computer network and information technology, the data that people need to store and use is increasing exponentially. Storage virtualization technology can reduce the management complexity of storage system. So that people only need to take advantage of the unified storage space after virtualization, without having to consider the details of physical storage devices, and at the same time can improve the utilization of storage devices. Saving the cost of storage devices. Storage virtualization technology has attracted extensive attention in recent years. Scholars from all over the world have carried out in-depth research. Storage virtualization has gradually become the storage development direction. ISCSI protocol is a technical standard based on IP protocol. This paper deeply studies the storage virtualization technology and the storage area network (San) theory, combined with the research of iSCSI protocol, An implementation scheme of SAN storage virtualization based on iSCSI is proposed. The main work is as follows:. In this paper, the principle and concept of storage virtualization are studied, and the advantages, classification and implementation of storage virtualization are described. The implementation of in-band storage virtualization and out-of-band storage virtualization is studied. Then the principle, content and implementation of SAN technology are described. Then, the basic protocol model of SCSI protocol and the SCSI command description block are studied. At the same time, the related theory of iSCSI is introduced, and the protocol stack, protocol data unit and the implementation flow of read and write operation of iSCSI protocol are studied. On the basis of the above contents, the structure of the start end and the target side of the iSCSI protocol, the workflow and the functions in the implementation, the thread and so on, are analyzed. Finally, this paper proposes a realization scheme of SAN storage virtualization based on iSCSI, and completes the design and implementation. The design and implementation of user logic volume management module and storage virtualization management configuration module in storage virtualization system are emphatically introduced. Meanwhile, the integration of storage resources and the data flow of storing user SCSI requests are described. The configuration information of storage devices and the configuration information of users are stored. Finally, the two modules are realized through the program. The feasibility of the proposed scheme is proved by testing, and the design and implementation of the whole system is relatively low. The utilization of storage resources can be greatly improved, so the solution has practical application value.
