Research on data block storage strategy in cloud storage system

With the development and progress of computer technology, data computing has been moving from traditional computing to cloud computing gradually. Cloud storage technology is an important part of cloud computing technology, and the replica technology is the key technology in the cloud storage system. According to the thinking of replica technology, this paper presents a new model of cloud storage problem, links the storage reliability to the physical performance of the underlying storage disk by modeling. Use the optimization algorithm to obtain the optimal solution. At the same time, we propose a new data block storage strategy. The MATLAB simulation results show that the new strategy can get the similar solution and reduce the operation time greatly compared to the optimization algorithm.
