【摘要】：云計算是一種支持共享的網(wǎng)絡(luò)交付信息服務(wù)的模式,云服務(wù)的使用者看到的只有服務(wù)本身,而不用關(guān)心相關(guān)基礎(chǔ)設(shè)施的具體實現(xiàn)。云計算的兩個本質(zhì)特征是資源虛擬化和處理并行化。資源虛擬化是對計算資源和存儲資源的邏輯表示,它不受物理限制的約束。 現(xiàn)有云存儲架構(gòu)技術(shù)的主要目標是解決如何在互聯(lián)網(wǎng)環(huán)境下對云計算、云存儲進行合理抽象,建立反映新一代存儲系統(tǒng)主要特征的云存儲系統(tǒng)架構(gòu)模型。這些研究的共同點是把存儲介質(zhì)視為云存儲的最小單元,云存儲未穿透該最小單元,因此未形成存儲介質(zhì)并行處理的云架構(gòu)。 本文主要針對存儲介質(zhì)的結(jié)構(gòu)開展研究,提出一種新型存儲結(jié)構(gòu)：基于云計算架構(gòu)的存儲信息系統(tǒng)(CBSIS)。CBSIS采用并行處理的云架構(gòu)組織文件管理系統(tǒng)與存儲介質(zhì),即在建立CBSIS元模型-問題求解模型(PRM)的基礎(chǔ)上,將文件管理系統(tǒng)與存儲介質(zhì)映射為原子構(gòu)件(AC)與PRM的引擎(E),用功能集成電路IP核實現(xiàn)AC的原子系統(tǒng)構(gòu)件(AS),并部署成PRM并行樹的葉節(jié)點,基于消息訪問PRM樹。最終形成云存儲架構(gòu)的片上系統(tǒng)(SSoC)。 論文從四方面重點闡述三個創(chuàng)新性研究成果：研究基于云計算架構(gòu)的存儲信息系統(tǒng)模型；基于該模型分析設(shè)計和驗證新一代CBSIS云存儲系統(tǒng)；最終實現(xiàn)基于CBSIS云存儲片上系統(tǒng)(SSoC)實物原型系統(tǒng)。 (1)通過可計算架構(gòu)的問題求解模型(PRM),課題建立了基于PRM元模型的云存儲系統(tǒng)架構(gòu)模型CBSIS,形成本文的第一個研究成果。本研究提出了針對具體問題建立問題求解模型的方法,包括建立概念模型、邏輯模型和物理模型的三層SOA架構(gòu)。物理模型映射為SOA的構(gòu)件,使構(gòu)件池的原子構(gòu)件集合的有限集可以通過邏輯模型的映射,表現(xiàn)概念模型的語義無窮集。構(gòu)件間是松耦合的,以消息的形式通過接口訪問,構(gòu)成云計算的資源虛擬化基礎(chǔ)。 (2)CBSIS體系結(jié)構(gòu)和總體框架的設(shè)計方案具有如下特點：(a)將體系結(jié)構(gòu)引入CBSIS系統(tǒng)設(shè)計；(b)將引擎E與體系結(jié)構(gòu)連接件CON相關(guān)聯(lián),使PRM的部署與CON的部署相一致。 通過提出和定義CBSIS應(yīng)用層語言LL7,并用連接件CON模型和構(gòu)件AC模型實現(xiàn)LL7,形成本研究的第二個創(chuàng)新點。 (3)以生成CBSIS可執(zhí)行原型系統(tǒng)為背景,討論了可執(zhí)行業(yè)務(wù)和可執(zhí)行架構(gòu)原型系統(tǒng),并提出了增量式原型系統(tǒng)的概念,可用于系統(tǒng)分析、設(shè)計和實現(xiàn)的各個階段。(4)本研究提出的云存儲片上系統(tǒng)SSoC解決方案,其特點是針對云存儲系統(tǒng)的現(xiàn)狀及未來發(fā)展趨勢,用于對云存儲基礎(chǔ)設(shè)施、管理平臺直至整個數(shù)據(jù)中心的分階段改造與部署實施。 論文以云存儲架構(gòu)的基礎(chǔ)設(shè)施改造為例,提出并實現(xiàn)本研究的第三個成果：基于SoW和bSATA控制器的SSoC。其SSoC是以集成文件管理系統(tǒng)模型和形成該模型要素的分層嵌套PRM樹結(jié)構(gòu)為特征的。 本研究提出的CBSIS架構(gòu)及其設(shè)計、驗證和原型系統(tǒng)生成與實現(xiàn)方法是針對云存儲應(yīng)用的,但使用的方法和工具具有普遍性,不局限于具體應(yīng)用領(lǐng)域。因此本研究提出的方法與理念適用于一般應(yīng)用系統(tǒng)的建模,具有快速開發(fā)與部署、易于測試和易于維護等特征。
[Abstract]:Cloud computing is a pattern that supports the shared network delivery of information services. The users of the cloud service see only the service itself, without care about the specific implementation of the related infrastructure. The two essential features of the cloud computing are the virtualization of resources and the parallelization of processing. It is not bound by physical restrictions.
The main goal of the existing cloud storage architecture technology is to solve cloud computing and cloud storage in the Internet environment, and to establish a cloud storage architecture model which reflects the main features of the new generation storage system. Therefore, there is no cloud architecture for parallel processing of storage medium.
This paper focuses on the structure of storage medium, and proposes a new storage structure: the storage information system based on cloud computing architecture (CBSIS).CBSIS adopts the parallel processing Cloud Architecture to organize file management system and storage medium, which is based on the establishment of the CBSIS meta model problem solving model (PRM) and the file management system and the file management system. The storage medium is mapped to the atomic component (AC) and the PRM engine (E), and the AC's atomic system component (AS) is implemented with the IP kernel of the functional integrated circuit, and is deployed into the node of the PRM parallel tree, and the PRM tree is accessed based on the message. Finally, the system on chip (SSoC) of the cloud storage architecture is formed.
This paper focuses on three innovative research results from four aspects: Research on the model of storage information system based on cloud computing architecture, and design and verify a new generation of CBSIS cloud storage system based on this model; finally, it is based on the prototype system of the system on the CBSIS cloud storage chip (SSoC).
(1) through the problem-solving model (PRM) of computable architecture (PRM), a cloud storage system architecture model based on PRM metamodel is established to form the first research result of this paper. This study proposes a method for establishing a problem solving model for specific problems, including the establishment of a conceptual model, a logical model and a physical model of the three layer SOA architecture. The physical model is mapped to the component of SOA. The finite set of the set of atomic components in the component pool can be mapped by the logical model, and the semantic infinite set of the conceptual model is expressed. The component is loosely coupled, and is accessed through the interface in the form of message, which forms the basis of the resource virtualization of the cloud computing.
(2) the design scheme of the CBSIS architecture and the overall framework has the following features: (a) introducing the architecture into the CBSIS system design; (b) associating engine E with the architecture connector CON to make the deployment of PRM consistent with the deployment of CON.
By proposing and defining the CBSIS application level language LL7, and implementing the LL7 with the connector CON model and the component AC model, second innovative points of this research are formed.
(3) with the background of generating CBSIS executable prototype system, the executable service and executable architecture prototype system are discussed, and the concept of incremental prototype system is proposed, which can be used in the various stages of system analysis, design and implementation. (4) the cloud storage system on the cloud storage system is proposed in this study, which is characterized by the present cloud storage system. And future development trend for cloud storage infrastructure, management platform until the entire data center staged transformation and deployment implementation.
This paper, taking the infrastructure transformation of cloud storage architecture as an example, proposes and implements third results of this study: the SSoC of SSoC. based on SoW and bSATA controller is characterized by the integrated file management system model and the hierarchical nested PRM tree structure forming the elements of the model.
CBSIS architecture and its design, design, verification and prototype system generation and implementation are applied to cloud storage, but the methods and tools used are universal, not limited to specific applications. Therefore, the methods and concepts proposed in this study are applicable to the modeling of general application systems, with rapid development and deployment and easy to measure. Test and easy to maintain and so on.
