Abstract :
Remote replication, also called remote mirror, is the key technology for data disaster tolerance. Compared with researchers, administrators of data center prefer to pay more attention to the influence factors of performance rather than how to implement remote replication and the technical details. In this paper, the influence factors to remote replication system are analyzed using a LVM-based remote replication system platform, named ELVM. ELVM is embedded into the LVM module of Linux. It uses NBD as data communication protocol. Experimental results and regression equations show that network QoS, which includes delay time, packet loss rate and packet corruption rate, takes much more influence on the system performance than user´s access mode. It implies improving network QoS is more important to remote replication system.
