    摘要: In the prior art clone creating technique of a file, a management table of a snapshot and the file was created when creating the clone file, so that a considerable amount of creation time for creating the clone file and storage capacity was required. In order to solve the problems of the prior art, the present invention provides a system wherein if a request to create a clone of a file is received, a differential file is created while inhibiting update of the file, and update data is written to the differential file. Further, when a first update request is received to the differential file after creating the differential file, a management table is created. According to the invention, a large amount of clone files can be created speedily.

    摘要: In a file storage service system, a computer stores files in a hybrid cloud. The computer comprises an extension metadata table which stores file storage conditions and target availability and an arrangement planned cloud table which stores a first identifier of a first cloud included in the hybrid cloud. The computer further comprises: an arrangement number calculation unit which selects a second cloud included in the hybrid cloud and satisfying the storage conditions and stores an identifier of the selected second cloud as the first identifier of the first cloud in the arrangement planned cloud table when availability of the selected second cloud satisfies the target availability; and a file arrangement management unit which stores a file uploaded from a client terminal in the first cloud identified by the first identifier stored in the arrangement planned cloud table by referring to the extension metadata table.

    摘要: A method and a storage system are provided for implementing a sustained large block random write performance mechanism for shingled magnetic recording (SMR) drives in a redundant array of inexpensive disks (RAID). A Solid State Drive (SSD) is provided with the SMR drives in the RAID. The SSD is used in a hot spare mode, which is activated when a large block random-write event is identified for a SMR drive in the RAID. In the hot spare mode, the SSD temporarily receives new incoming writes for the identified SMR drive. Then the identified SMR drive is updated from the SSD to restore the state of the identified SMR drive, and operations continue with normal writing only using the SMR drives in the RAID.

    摘要: The system of the present invention curbs an unnecessary inter-tier file migration and provides an inter-tier file migration that conforms to the utilization state. The hierarchical storage management system respectively migrates a frequently accessed file to the upper Tier, and an infrequently accessed file to the lower Tier. This system carries out inter-tier file migration in conformance with the utilization state. This system provides functions for anchoring a Tier for storage for a specified file, and for not permitting an inter-tier file migration.

    摘要: To inhibit deterioration in the I/O performance of a file even if the file includes an area that is frequently accessed.An access account of the file is recorded, an area of the file is split into a plurality of partial areas at least one or more times if the access count exceeds a split threshold, the partial area (partial area including a hotspot with frequent access) in which the access count exceeded the split threshold is minimized, data corresponding to that partial area is ultimately uncompressed, and data corresponding to the other partial areas is compressed.

    摘要: When performing migration of data from a migration source file server which is not endowed with any HSM interface, to a migration destination file server which is endowed with HSM, a volume of high capacity is needed for the migration destination file server, and moreover the performance deteriorates directly after the migration. However, with this system, the manager is enabled to set a migration policy using attribute information which can be acquired through a standard file access interface possessed by a file server program, and, when setting the attribute information of the migration destination file, the tier of the file which is to be created is determined, and the migration destination file is created, on the basis of this attribute information and migration policy.
