【摘要】：隨著信息化科技的發(fā)展,人們對(duì)計(jì)算資源和存儲(chǔ)資源的需求不斷的增加。云計(jì)算的提出能夠很好的解決因需求增長(zhǎng)帶來(lái)的資源利用問(wèn)題。同時(shí)伴隨著虛擬化技術(shù)逐漸成熟,尤其是在服務(wù)器領(lǐng)域,越來(lái)越多的公司考慮利用一些開(kāi)源的虛擬化技術(shù)來(lái)構(gòu)建云計(jì)算平臺(tái),來(lái)提供公有云服務(wù)或滿(mǎn)足自身的私有云需求。 無(wú)論是何種類(lèi)型的云平臺(tái),其計(jì)算和存儲(chǔ)都是圍繞虛擬機(jī)來(lái)展開(kāi)。為了根據(jù)統(tǒng)一的虛擬機(jī)鏡像提供一些可定制化的鏡像服務(wù),以及保證虛擬機(jī)的容災(zāi)能力和高可用性,眾多云平臺(tái)解決方案都提供了快照的功能。針對(duì)快照過(guò)程,本文以開(kāi)源的云計(jì)算平臺(tái)為實(shí)驗(yàn)平臺(tái),結(jié)合寫(xiě)前拷貝的存儲(chǔ)快照技術(shù),介紹了兩種方案來(lái)加快快照和恢復(fù)速度,減少網(wǎng)絡(luò)傳輸和快照文件存儲(chǔ),提高快照效率。針對(duì)快照鏡像存儲(chǔ),本文采用三種數(shù)據(jù)去重的方式,設(shè)計(jì)了快照鏡像去重存儲(chǔ)的方案來(lái)減少鏡像服務(wù)器的存儲(chǔ)壓力。最后對(duì)各種方案進(jìn)行了實(shí)驗(yàn)對(duì)比和分析,在快照過(guò)程優(yōu)化方案中,采用本文的快照優(yōu)化方案,虛擬機(jī)快照和恢復(fù)速度明顯加快。在快照鏡像存儲(chǔ)中,應(yīng)用了本文的去重方案可以有效的減少重復(fù)數(shù)據(jù)的存儲(chǔ),減輕存儲(chǔ)壓力。
[Abstract]:With the development of information technology, the demand for computing resources and storage resources is increasing. Cloud computing can solve the problem of resource utilization caused by increasing demand. At the same time, the virtualization technology is gradually mature. Especially in the server field, more and more companies are considering using some open source virtualization technology to build cloud computing platform to provide public cloud services or meet their own private cloud needs. Regardless of the type of cloud platform, its computation and storage are centered around virtual machines. To provide customized mirroring services based on unified virtual machine mirroring, and to ensure disaster tolerance and high availability of virtual machines, Many cloud platform solutions provide the function of snapshot. Aiming at the snapshot process, this paper takes open source cloud computing platform as the experimental platform and introduces two kinds of schemes to accelerate the snapshot and restore speed. Reduce network transmission and snapshot file storage, improve snapshot efficiency. In order to reduce the storage pressure of the mirror server, this paper designs a scheme of removing and restoring the snapshot image. Finally, the experimental comparison and analysis of the various schemes are carried out. In the optimization scheme of the snapshot process, the snapshot optimization scheme of this paper is adopted. The speed of snapshot and recovery of virtual machine is accelerated obviously. In snapshot mirror storage, the reshuffling scheme of this paper can effectively reduce the storage of duplicate data and reduce the storage pressure.
