【摘要】：隨著信息技術(shù)的發(fā)展,企業(yè)的生產(chǎn)經(jīng)營對于電子數(shù)據(jù)的依賴越來越大。很多企業(yè)面對大量數(shù)據(jù)存在存儲,管理,使用等一系列問題。網(wǎng)絡(luò)附屬存儲(Network Attached Storage,簡稱NAS)產(chǎn)品在數(shù)據(jù)存儲領(lǐng)域由于具有用途專一,性價比高,支持多種數(shù)據(jù)傳輸協(xié)議的特點而被很多企業(yè)采用。傳統(tǒng)的NAS產(chǎn)品是基于單個節(jié)點,存在先天性的缺陷。其可靠性差,擴展困難等缺點難以適應(yīng)當(dāng)代企業(yè)全天候數(shù)據(jù)服務(wù)的需求。 本文將介紹一個可擴展的NAS產(chǎn)品,它是基于IBM公司的通用并行文件系統(tǒng),可以在提供數(shù)據(jù)服務(wù)的同時進(jìn)行擴展,備份等操作�？蓴U展NAS產(chǎn)品提供了基于B/S的管理系統(tǒng),易于部署和管理。此外,企業(yè)可以根據(jù)當(dāng)前數(shù)據(jù)量對節(jié)點數(shù)目進(jìn)行調(diào)整,可以有效降低采購和運營成本。本文以可擴展NAS產(chǎn)品為項目背景,詳細(xì)介紹了其集群模塊的分析,設(shè)計和實現(xiàn)。 本文首先介紹了可擴展NAS產(chǎn)品的背景,以及國內(nèi)外NAS產(chǎn)品發(fā)展的現(xiàn)狀。介紹可擴展NAS產(chǎn)品集群模塊在項目中的作用和地位。介紹了產(chǎn)品網(wǎng)絡(luò)層,數(shù)據(jù)層,服務(wù)層,表現(xiàn)層的四層架構(gòu)。 接著本文介紹了在集群模塊開發(fā)過程中使用的技術(shù)和工具。 然后,本文在需求分析的基礎(chǔ)上介紹了集群模塊的設(shè)計和實現(xiàn)。詳細(xì)分析了集群模塊的四個主要的功能子模塊,網(wǎng)絡(luò)通信子模塊,節(jié)點管理子模塊,權(quán)限管理子模塊和性能監(jiān)控子模塊。本文對各個子模塊的功能設(shè)計,關(guān)鍵流程設(shè)計進(jìn)行了闡述,并且詳細(xì)分析了關(guān)鍵的實現(xiàn)細(xì)節(jié)。 最后,本文對所做的工作進(jìn)行了總結(jié),并且指出了集群模塊在節(jié)點管理方面可以繼續(xù)展開的工作。
[Abstract]:With the development of information technology, the production and management of enterprises depend more and more on electronic data. Network attached Storage Network Attached Storage (NAS) products in the field of data storage because of their unique use, high cost-effective, Traditional NAS products are based on a single node and have inherent defects, such as poor reliability, difficult expansion and so on, which are difficult to adapt to the demand of all-weather data service in modern enterprises. This paper will introduce an extensible NAS product, which is based on the general parallel file system of IBM Company. It can provide data service while extending, backup and so on. The extensible NAS product provides a management system based on B / S. It is easy to deploy and manage. In addition, enterprises can adjust the number of nodes according to the current data volume, which can effectively reduce the purchasing and operating costs. This paper introduces the analysis of its cluster modules in detail, taking extensible NAS products as the project background. Design and implementation. This paper first introduces the background of extensible NAS products and the development of NAS products at home and abroad, introduces the role and status of extensible NAS product cluster modules in the project, and introduces the product network layer, data layer, service layer, etc. The four-tier architecture of the presentation layer. Then this paper introduces the technology and tools used in cluster module development. Then, on the basis of requirement analysis, this paper introduces the design and implementation of cluster module, and analyzes in detail the four main functional sub-modules of cluster module, network communication sub-module, node management sub-module, network communication sub-module, network communication sub-module, node management sub-module, network communication sub-module and node management sub-module. In this paper, the function design and key flow design of each sub-module are described, and the key implementation details are analyzed in detail. Finally, this paper summarizes the work done, and points out that the cluster module can continue to work in the aspect of node management.
