【摘要】：对虚拟计算机数据存储空间的稳定性进行优化,可以有效缓解数据的存储压力。对数据存储空间的稳定性优化,需要根据历史数据和当前数据的交界区域,得到数据存储空间稳定性优化阈值。传统方法通过给出数据存储的约束条件,得到数据存储的理想状态函数,但无法得到存储空间优化阈值,导致优化精度低。提出基于预分块和滑动窗口的虚拟计算机数据存储空间稳定性优化方法。融合于动态指针方法给定实验室系统数据流无穷序列,划分出数据变动区域和非变动区域,提取数据中的冗余元素,计算出重复数据存储率,采用滑动窗口给出上限值与实际值之间的差值,根据历史数据和当前数据的交界区域,得到存储空间稳定性优化阈值,完成对虚拟计算机数据存储空间稳定性优化。实验证明,所提方法数据存储安全性高,极大地提升了计算机存储空间,保障了虚拟虚拟计算机灵活性和稳定性。
[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.
