    摘要: Provided is a storage controller capable of changing a system configuration with scalability. A storage controller blade of the storage controller includes: interface units that each connect to one of a host computer and a disk device; a processor unit that controls a configuration of the storage controller and data access; a memory unit that stores a data cache and configuration information on the interface unit and the processor unit; and a mutual connection unit that connects the interface units, the processor unit, and the memory unit to one another. The processor unit recognizes a form of connection to another storage controller blade over the mutual network, and the connection path to another storage controller blade is set in the mutual connection unit based on the recognized form of connection.

    摘要: A method and storage system for increasing an amount of memory in a queuing area on. The storage system includes first and second storage subsystems connected to each other via a path. A primary volume in the first storage subsystem and a remote secondary volume in the second storage subsystem are mirrored and operated in the asynchronous mode. A queuing area having memory is provided in the second storage subsystem for temporarily storing data transferred to the second storage subsystem from the first storage subsystem in response to a write input/output (I/O) issued by a host to write data in the primary volume. Data temporarily stored in the memory is retrieved and stored in the remote secondary volume. An unused area of the queuing area is monitored and the memory increased if the unused area becomes less than a predetermined amount.

    摘要: A system of volume health checking and recovery. The system comprises a health engine capable to check the health of a first volume that is a snapshot mirrored volume of a second volume; and a recovery engine, communicatively coupled to the health engine, capable to perform a recovery process if the first volume is unhealthy. Recovery can be performed via at least one of five methods.
