METHOD FOR MIRRORING NETWORK DATA TO ESTABLISH VIRTUAL STORAGE AREA NETWORK AND VIRTUAL STORAGE AREA NETWORK

摘要

Will use the shared physical storage node is without a security protocol modules 311 and 321 and the mirror engine (317 and 327) to mirror data to provide a storage area network (340) of the virtual. Mirror engines (317 and 327) are each in the network 301 receives the server a write operation, and mirroring data between a mass storage device (319, 320) of the server when executing a respective mass storage device to include the same stored data It exists on the server computer (310, 320). Security protocols (311, 321) is to prevent data corruption by not allowing the one or more servers (310 and 320) is to write the data files at once. A server (310 and 320) is Nago failure if you can provide a connection to the network data, there another server or servers to service all of the read request, which all network data is because the accessible by all servers. Unlike a conventional storage area network, any physical shared memory node is not present and therefore, the cost of operating the gain storage area network 340, the virtual is relatively inexpensive. ; Virtual, storage, sharing, network, security protocol modules, mirroring, memory
