Abstract: |
A method of the virtual intelligent controller in SAN system, belonging to storage area network field. The characteristics of the invention is that: introduce virtual intelligent controller to the data path in SAN, to divide SAN system into two independent subsystems of equipment SAN and host SAN. Thereinto the equipment SAN takes charge of the organization and management of storage resource, while the host SAN only need to pay attention to the usage of storage resource. The virtual intelligent controller is between both of them, and is the relation link of equipment SAN and host SAN. It can manage all kinds of storage equipments and can provide uniform storage resource view to the isomerous host SAN, so as to simplify the management of the storage resource. Besides the visit control management of the virtual intelligent controller provides the validating function to I/O request jurisdiction, to prevent data damage caused by illegal operation. It is very suitable to effectively manage the isomerous storage resource in the isomerous application server environment, and provides a kind of efficient solving method to the increasingly complex storage management. |
