摘要： A root node creates and issues an object ID comprising share information designating a share unit, which is a logical public unit. The share unit is a logical public unit comprising no less than two objects. Transfer control information in which share information is associated with device information showing a device for managing this share unit, is prepared for each share unit. The root node receives request data, which has an object ID comprising share information, specifies device information corresponding to the share information in this object ID from the transfer control information, and transfers the request data to the device indicated in this device information.

摘要： Provided is a computer system containing plural storage systems which manages the bandwidth of the storage systems in accordance with storage area attributes. The computer system is characterized in that: a control unit incorporates related file information in metadata, the related file information containing information for identifying a second file which to be write-accessed in conjunction with access to a first file by a client computer, and an access type of the write access. The control unit refers to the related file information to obtain the second file and the access type when the first file is accessed by the client computer. The control unit reads, from the obtained second file stored in the disk device, data corresponding to the obtained access type, to store the read data in a cache memory.

摘要： A storage system includes a plurality of nonvolatile memory devices that each includes a plurality of nonvolatile memory chips, and a storage controller configured to perform input and output of data to and from a RAID group comprised by storage areas of the plurality of nonvolatile memory devices. A nonvolatile memory device identifies a failure occurrence area that is a storage area in which a failure occurred in the plurality of nonvolatile memory chips, excludes the failure occurrence area from a storage area allocated to the RAID group, and transmits failure occurrence information that is information relating to the failure that has occurred in the nonvolatile memory device to the storage controller. When the failure occurrence information is received, the storage controller reconstructs data that had been stored in a storage area including at least the failure occurrence area of the nonvolatile memory device.

摘要： A storage device is provided with a file I/O interface control device and a plurality of disk pools. The file I/O interface control device sets one of a plurality of storage hierarchies defining storage classes, respectively, for each of LUs within the disk pools, thereby forming a file system in each of the LUs. The file I/O interface control device migrates at least one of the files from one of the LUs to another one of the LUs of an optimal storage class, based on static properties and dynamic properties of each file.
