    • An adaptive read/write optimized algorithm for Ceph heterogeneous systems via performance prediction and multi-attribute decision making
    Authors: Zhike, Li; Yong, Wang;  Advisor: -;  Co-Author: - (2023)

    The advent of the Big Data era has brought considerable challenges to storing and managing massive data. Moreover, distributed storage systems are critical to the pressure and storage capacity costs. The Ceph cloud storage system only selects data storage nodes based on node storage capacity. This node selection method results in load imbalance and limited storage scenarios in heterogeneous storage systems. Therefore, we add node heterogeneity, network state, and node load as performance weights to the CRUSH algorithm and optimize the performance of the Ceph system by improving load balancing. We designed a cloud storage system model based on Software Defined Network (SDN) technology....
