The Performance of the Data-Cluster Based on the CEPH Platform with Geographically Separated Nodes

摘要

This paper is focused to the designing, implementing and benchmarking the data cluster based on the CEPH [1] technology. The main point of this paper is aimed to the implementation with geographically separated nodes. These nodes, store points of distributed data cluster, is in different location and on different subnets. Realized test show the dependency of number of concurrent clients connected to the cluster and cluster read/write bandwidth. These test show the potential limits of the developed solution.
