Construction of Virtual Private Network for remote disaster-tolerant channel based on "SG186 Network"

The rapid development of the grid and communication technology for raising the level of power management automation provides a strong condition. Traditional data replication system in rural power network has not keep up with the pace of modernization, the change the traditional and inefficient data replication system has become the goal of power enterprises. Aiming at the deficiency of FC-SAN technology introduced based on the IP-SAN disaster recovery technology. This follows the State gird Second Power Equipment safety regulations, according to state grid and needs of automation, using "SG186 network" to construct a remote data backup system based on IP-SAN. Using the ISCSI protocol to construct IP-SAN is more suitable for using IP network for remote data transmission. The system can realize dispatching data integration, realize the standardization of data and application, and improve the safety of grid operation. Operation shows that the system design is reasonable, so this data replication system will have good generality and application value in power network.
