【摘要】：伴隨著信息技術(shù)的發(fā)展，數(shù)據(jù)量呈爆炸式增長，給數(shù)據(jù)的存儲和處理帶來了越來越大的挑戰(zhàn)。新的技術(shù)不斷應(yīng)用到已有的存儲系統(tǒng)中，用來擴(kuò)展存儲系統(tǒng)的容量和提高存儲系統(tǒng)的性能以及資源利用率。針對這種現(xiàn)狀，提出構(gòu)建一個(gè)重定向框架，嵌入豐富的高級存儲策略，改善現(xiàn)有的存儲系統(tǒng)。初步實(shí)現(xiàn)了重定向的框架程序，定義了存儲策略的嵌入接口，并實(shí)現(xiàn)了一種自定義的快照策略，為現(xiàn)有存儲平臺提供數(shù)據(jù)保護(hù)功能。 深入研究了幾類通用的存儲系統(tǒng)架構(gòu)，提出了實(shí)現(xiàn)重定向技術(shù)的兩種方式：帶內(nèi)和帶外。從重定向的視角，分析了多種高級存儲特性的實(shí)現(xiàn)方案，論證了重定向框架的可行性。改造現(xiàn)有的存儲系統(tǒng)，，可以采取帶外的方式實(shí)現(xiàn)一個(gè)重定向框架程序，兼容現(xiàn)有的存儲方案，并把對現(xiàn)有系統(tǒng)的改動降到最低。可以靈活地嵌入自動精簡配置、重復(fù)數(shù)據(jù)刪除、快照等高級存儲策略，提高存儲平臺的可用性和存儲資源的利用率。實(shí)現(xiàn)了一個(gè)獨(dú)立于存儲系統(tǒng)的重定向框架程序。重定向框架明確定義了存儲策略的嵌入接口，可以靈活地支持多策略的共生，同時(shí)完全兼容現(xiàn)有的存儲方案。在重定向框架的基礎(chǔ)上，實(shí)現(xiàn)了一種自定義的快照存儲策略。這種快照策略按照虛擬視圖的方式實(shí)現(xiàn)，將原始邏輯卷改造成自定義的磁盤格式，能夠支持無上限次數(shù)的快照，同時(shí)存儲性能與快照次數(shù)無關(guān)。 對于實(shí)現(xiàn)快照功能的重定向框架進(jìn)行了相關(guān)測試。首先測試了運(yùn)行空策略的框架程序，結(jié)果表明帶外實(shí)現(xiàn)的框架程序?qū)τ诂F(xiàn)有存儲平臺的影響很小，對存儲策略的支持符合設(shè)計(jì)指標(biāo)。然后對快照策略進(jìn)行了功能和性能的測試，測試結(jié)果表明，嵌入重定向框架的快照策略可以正確地完成設(shè)計(jì)的功能，相關(guān)性能符合設(shè)計(jì)的預(yù)期效果。
[Abstract]:With the development of information technology, the amount of data increases explosively, which brings more and more challenges to the storage and processing of data. It is used to expand storage system capacity and improve storage system performance and resource utilization. In view of this situation, a redirection framework is proposed to embed rich advanced storage strategies. The redirected frame program is implemented, the embedded interface of storage policy is defined, and a self-defined snapshot policy is implemented to provide data protection for the existing storage platform. In this paper, several kinds of general storage system architecture are deeply studied, and two ways to realize redirection technology are put forward: in-band and out-of-band. From the perspective of redirection, the realization schemes of various advanced storage characteristics are analyzed. The feasibility of redirect frame is demonstrated. By modifying the existing storage system, a redirect frame program can be implemented in an out-of-band manner, which is compatible with existing storage schemes. And to minimize the changes to the existing system. Flexible embedded automatic reduction configuration, duplicate data deletion, snapshot and other advanced storage strategy, To improve the availability of storage platform and the utilization of storage resources, a redirection framework program independent of storage system is implemented. The redirection framework clearly defines the embedded interface of storage policy, and can flexibly support the coexistence of multiple policies. At the same time, it is fully compatible with the existing storage schemes. On the basis of the redirection framework, a customized snapshot storage strategy is implemented. The snapshot strategy is implemented in the form of virtual view, and the original logical volume is transformed into a custom disk format. Can support unlimited number of snapshots, while the storage performance is independent of the number of snapshots. First, the framework program running empty policy is tested. The results show that the out-of-band framework program has little effect on the existing storage platform. Then the function and performance of the snapshot policy are tested. The test results show that the snapshot policy embedded in the redirect framework can accomplish the designed function correctly. The related performance is in line with the desired effect of the design.
