摘要： An information processing system having a storage apparatus and a file sharing server. The storage apparatus comprises a plurality of storage devices for providing logical devices to store data; and a first processing unit for providing virtual logical units based on a mapping relation between the logical devices and the virtual logical units and being operative to switch the mapping relation dynamically according to an external request. The file sharing server comprises a cache memory including cache extents and a second processing unit controlled to provide the virtual logical units of the storage apparatus to a host system by using the cache extents, managing the mapping relation between the logical devices and the virtual logical units. The mapping between a logical unit and a logical device is dynamically switched as the logical devices store data provided from the host system according to external requests.

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： Problem: Providing a storage system which can be applied to a broad range of access forms to the file and, at the same time, in which the performance of file access control processing is improved. Solution: The storage system stores a part of the access control information of a variable size in the basic attribute area of the file, and stores the storage format information in the basic attribute area of the file or in the file system metadata area. At the time of processing the access to the file, with reference to the storage format information, the storage system decodes a part of the access control information into an access mask bit string as needed, and performs the preceding access control processing. If whether access is permitted or not can be determined through the preceding access control processing, the access control processing is performed while, whether access is permitted or not cannot be determined, performs the access control processing based on the extended attribute information.FigureFIG. 7

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： It is provided a storage system including a storage device for storing data, and a controller for controlling data read/write in the storage device. The controller includes a processor for executing a program, and a memory for storing the program that is executed by the processor. The processor executes deduplication processing for converting a duplicate part of data that is stored in the storage device into shared data, and calculates a distributed capacity consumption, which represents a capacity of a storage area that is used by a user in the storage device, by using a size of the data prior to the deduplication processing and a count of pieces of data referring to the shared data that is referred to by this data.
