Method to Improve the Performance of CEPH Storage Based on Network Delay

This article propose an new method based on weight of network delay by analysis the relationship of one node's network delay and the storage performance of CEPH. The experiments show that the method could adjust the node's weight depended on the network delay of that node, so that data files could be stored in good network performance with greater probability. This new method reduces the time cost caused by network delay and improves the performance of CEPH storage system in that case.
