Research and application of distributed storage technology in power grid enterprise database

At present, the physically independent database servers of power grid enterprises are connected through the network to form a logical cluster system. Then they can continue to provide services even if some servers crash because of various accidents. This paper firstly discussed the application of distributed storage technology in power grid enterprise database cluster system, and then presented the active-active architecture based on distributed consistent state machine. Furthermore, a solution of Oracle real application cluster without shared storage is proposed. The schemes are applied to an experimental system of a power grid enterprise. Experimental results show that the schemes have good reusability and scalability, and improve the operation efficiency and high reliability of the system.
