    摘要: Access to various types of resources is controlled efficiently, thereby enhancing the throughput. A storage system includes: a disk device for providing a volume for storing data to a host system; a channel adapter for writing data from the host system to the disk device via a cache memory; a disk adapter for transferring data to and from the disk device; and at least one processor package including a plurality of processors for controlling the channel adapter and the disk adapter; wherein any one of the processor packages includes a processor for incorporatively transferring related types of ownership based on specific control information for managing the plurality of types of ownership for each of the plurality of types of resources.

    摘要: A storage control technique with which, even if not data, but only its management information is deleted, a host system can recognize storage areas storing unnecessary data and so use them effectively. When a file system in the host system deletes the management information for data stored in a page in a pool volume, a control circuit writes ‘0’ in all the areas in the deletion target page in response to a command from the host system. The control circuit then detects the page where ‘0’ is written in all of its areas and releases it from allocation to the corresponding virtual volume.

    摘要: The present invention reduces the amount of rebuild processing and executes a rebuild process efficiently. Multiple storage devices configure a parity group. Of the multiple storage devices, a prescribed storage device in which a failure has occurred is blocked. Each storage device stores management information. The management information manages from among the storage areas of the storage device a prescribed area having data from a higher-level apparatus. A controller determines whether a storage area of the prescribed storage device is the prescribed area based on the management information, and executes a rebuild process with respect to the area determined to be the prescribed area.

    摘要: A storage controller having a plurality of storage devices and a control circuit providing a plurality of virtual volumes, to each of which a storage area in a plurality of pool volumes provided with the plurality of storage devices can be mapped for writing data in response to a write access sent from an information processing apparatus to a logical area in one of the plurality of virtual volumes, respectively. The control circuit, according to a search of the plurality of pool volumes for a certain storage area in which a certain data pattern is written, releases the certain storage area from mapping to a logical area in the plurality of virtual volumes, so that the control circuit can use the released certain storage area for mapping to a virtual volume of the plurality of virtual volumes as a destination of another write access from the information processing apparatus.

    摘要: Provided is a storage subsystem capable of speeding up the input/output processing for a cache memory. Microprocessor Packages manage information related to a VDEV ownership for controlling virtual devices and a cache segment ownership for controlling cache segments in units of Microprocessor Packages, and one Microprocessor among multiple Microprocessors belonging to the determined Microprocessor Package to perform input/output processing for the virtual devices searches cache control information stored in the Package Memory without searching the cache control information in the shared memory, and if data exists in the cache memory, accesses the cache memory, and if it does not, accesses the virtual devices.
