【摘要】：自因特網(wǎng)流行以來，網(wǎng)絡(luò)數(shù)據(jù)數(shù)量以前所未有的速度增長(zhǎng)著，傳統(tǒng)的存儲(chǔ)模式已經(jīng)無法跟上數(shù)據(jù)增長(zhǎng)的腳步。而基于網(wǎng)絡(luò)存儲(chǔ)的云存儲(chǔ)(Cloud Storage)是解決數(shù)據(jù)存儲(chǔ)問題的主力軍。其發(fā)展?jié)摿Σ粌H表現(xiàn)在它那低廉的代價(jià)和安全的服務(wù)，，更為重要的是它能夠讓客戶只需擁有輸入輸出終端就能夠正常工作。 傳統(tǒng)云存儲(chǔ)的商業(yè)運(yùn)營(yíng)結(jié)構(gòu)是客戶直接與云存儲(chǔ)運(yùn)營(yíng)商交互。由于訪問接口、收費(fèi)機(jī)制、數(shù)據(jù)存放形式等原因，客戶存放在多個(gè)云存儲(chǔ)運(yùn)營(yíng)商上的數(shù)據(jù)無法相互交互。典型的云存儲(chǔ)拓?fù)浣Y(jié)構(gòu)Master-Slave和P2P都存在各自的不足。為云存儲(chǔ)系統(tǒng)設(shè)計(jì)了一種新的商業(yè)運(yùn)營(yíng)模式，在該商業(yè)模式的基礎(chǔ)上分別從功能、拓?fù)浣Y(jié)構(gòu)為云存儲(chǔ)設(shè)計(jì)了一種結(jié)構(gòu)。該結(jié)構(gòu)能夠解決存放在多個(gè)存儲(chǔ)運(yùn)營(yíng)商上的數(shù)據(jù)相互交互問題，客戶可以根據(jù)自己的需要去選擇安全級(jí)別，同時(shí)融合Master-Slave和P2P兩種拓?fù)浣Y(jié)構(gòu)的優(yōu)點(diǎn)。在這個(gè)結(jié)構(gòu)基礎(chǔ)上，對(duì)云存儲(chǔ)系統(tǒng)進(jìn)行抽象分析，運(yùn)用元胞自動(dòng)機(jī)理論為存儲(chǔ)元胞設(shè)定狀態(tài)、狀態(tài)轉(zhuǎn)換策略，通過系統(tǒng)的自我調(diào)節(jié)，可以解決負(fù)載均衡、熱點(diǎn)數(shù)據(jù)處理以及數(shù)據(jù)副本控制等問題。 通過在CloudSim上部署仿真模型，采用隨機(jī)訪問請(qǐng)求生成機(jī)制，分別對(duì)只有讀請(qǐng)求和讀寫請(qǐng)求共同存在兩種情況進(jìn)行仿真。使用matlab工具對(duì)仿真數(shù)據(jù)進(jìn)行分析。仿真結(jié)果表明，為存儲(chǔ)元胞設(shè)置好狀態(tài)和狀態(tài)轉(zhuǎn)變規(guī)則后，系統(tǒng)將能夠靠自我調(diào)節(jié)來實(shí)現(xiàn)負(fù)載均衡，同時(shí)處理熱點(diǎn)數(shù)據(jù)的發(fā)生和數(shù)據(jù)副本數(shù)量的控制。
[Abstract]:Since the popularity of the Internet, the amount of online data has grown at an unprecedented rate. The traditional storage mode has been unable to keep up with the growth of data. Cloud Storage based on Network Storage is the main force to solve the problem of data storage. More importantly, it enables customers to function as long as they have an I / O terminal. The traditional business operation structure of cloud storage is that customers interact directly with cloud storage operators. The data stored by customers on multiple cloud storage operators cannot interact with each other. Typical cloud storage topology Master-Slave and P2P have their own shortcomings. A new business operation mode is designed for cloud storage system. On the basis of the business model, a structure is designed for cloud storage from function and topology, which can solve the problem of data interaction between multiple storage operators. Customers can choose the security level according to their own needs, and combine the advantages of Master-Slave and P2P topology. Based on this structure, the cloud storage system is analyzed abstractly, and the state of storage cell is set by using cellular automata theory. The strategy of state transition can solve the problems of load balancing, hot data processing and data copy control through self-adjustment of the system. By deploying the simulation model on CloudSim and adopting the random access request generation mechanism, we simulate the two situations of only read request and read and write request respectively. The simulation data are analyzed by using matlab tool. The simulation results show that there are only read requests and read and write requests. After setting up state and state transition rules for storage cells, the system will be able to achieve load balancing by self-adjustment, at the same time, it can handle the occurrence of hot data and the control of the number of data replicas.
