【摘要】：對(duì)虛擬計(jì)算機(jī)數(shù)據(jù)存儲(chǔ)空間的穩(wěn)定性進(jìn)行優(yōu)化,可以有效緩解數(shù)據(jù)的存儲(chǔ)壓力。對(duì)數(shù)據(jù)存儲(chǔ)空間的穩(wěn)定性優(yōu)化,需要根據(jù)歷史數(shù)據(jù)和當(dāng)前數(shù)據(jù)的交界區(qū)域,得到數(shù)據(jù)存儲(chǔ)空間穩(wěn)定性優(yōu)化閾值。傳統(tǒng)方法通過給出數(shù)據(jù)存儲(chǔ)的約束條件,得到數(shù)據(jù)存儲(chǔ)的理想狀態(tài)函數(shù),但無法得到存儲(chǔ)空間優(yōu)化閾值,導(dǎo)致優(yōu)化精度低。提出基于預(yù)分塊和滑動(dòng)窗口的虛擬計(jì)算機(jī)數(shù)據(jù)存儲(chǔ)空間穩(wěn)定性優(yōu)化方法。融合于動(dòng)態(tài)指針方法給定實(shí)驗(yàn)室系統(tǒng)數(shù)據(jù)流無窮序列,劃分出數(shù)據(jù)變動(dòng)區(qū)域和非變動(dòng)區(qū)域,提取數(shù)據(jù)中的冗余元素,計(jì)算出重復(fù)數(shù)據(jù)存儲(chǔ)率,采用滑動(dòng)窗口給出上限值與實(shí)際值之間的差值,根據(jù)歷史數(shù)據(jù)和當(dāng)前數(shù)據(jù)的交界區(qū)域,得到存儲(chǔ)空間穩(wěn)定性優(yōu)化閾值,完成對(duì)虛擬計(jì)算機(jī)數(shù)據(jù)存儲(chǔ)空間穩(wěn)定性優(yōu)化。實(shí)驗(yàn)證明,所提方法數(shù)據(jù)存儲(chǔ)安全性高,極大地提升了計(jì)算機(jī)存儲(chǔ)空間,保障了虛擬虛擬計(jì)算機(jī)靈活性和穩(wěn)定性。
[Abstract]:To optimize the stability of data storage space of virtual computer, it can effectively relieve the pressure of data storage. To optimize the stability of data storage space, it is necessary to optimize the stability of data storage space according to the boundary region between historical data and current data. The optimal threshold of data storage space stability is obtained by the traditional method, the ideal state function of data storage is obtained by giving the constraint condition of data storage, but the optimal threshold value of storage space can not be obtained. In this paper, a method of optimizing the spatial stability of virtual computer data storage based on pre-partitioning and sliding window is proposed. The method is integrated with the dynamic pointer method to give the infinite sequence of the data stream of the laboratory system. The data variable region and the non-variable region are divided, the redundant elements in the data are extracted, the duplicate data storage rate is calculated, the difference between the upper limit value and the actual value is given by the sliding window, and according to the boundary region between the historical data and the current data, the difference between the upper limit value and the actual value is given by the sliding window. The optimization threshold of storage space stability is obtained, and the stability optimization of virtual computer data storage space is completed. Experiments show that the proposed method has high data storage security and greatly improves the computer storage space. It ensures the flexibility and stability of virtual computer.
