A distributed and unstructured data copy management model

Lin, Zhang Wanjun, Sun

Aiming at the delay response of data replica management in cloud storage System, a distributed replica management model oriented to unstructured data is proposed. This model adopts the frame election algorithm to reduce the overall energy consumption of the system by improving the utilization ratio of each rack, and provides technical support for the Green data center. In order to improve system performance, balance load and resource utilization, a multiple-route hashing algorithm is used to distribute the data copy dynamically and evenly across different frame nodes. Simulation results show that compared with the traditional global mapping method, the model can achieve high storage and load balance, and has good scalability and usability.
