中文摘要：
通过分析集群中单节点在不同网络延时下的延时大小与集群存储性能的关系,提出基于网络时延的权重改进方法.实验表明所提出的方法可根据存储节点的网络时延对权重进行再调整,使数据较大概率存入网络时延小的节点.该方法降低了由单一节点网络延时引起的存储性能损耗,从而提高了CEPH分布式存储系统的存储性能.
英文摘要：
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 ease.
