【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.
[Abstract]:Through the relationship between the single node in the cluster analysis in different network delay delay under the cluster size and storage performance, put forward the improvement method of weighted network based on delay. Experiments show that the proposed method can be adjusted according to the weight of the network delay storage node, the data is stored in the nodes of the network delay probability. This method reduces the the storage performance loss caused by a single node of the network delay, so as to improve the storage performance of CEPH distributed storage system.
