  • Publication number: 20170068600
    Abstract: A file on file storage is archived as an object on object storage. In this case, a correspondence between UUID which is an identifier of the object and a path or an inode number which is an identifier of the file is recorded. This is referred to as correlation between the file and the object. However, because of changing of the path due to the renaming of the file, or changing of the inode number due to overwriting of the file, the correlation is likely to be lost. The invention provides a technique that restores the lost correlation and causes the correlation between the file and the object to be maintained.

  • Publication number: 20170019345
    Abstract: In a system, such as a cloud, which allows resource allocation to be flexibly changed in a multi-tenant environment, it is necessary to interchange resources between the tenants. Efficient resource coordination for resource allocation cannot be attained by merely adjusting resource allocation amounts or resource usage amounts. In order to address this problem, the present invention selects an optimum allocation method from among a plurality of resource allocation methods including CPU capping, taking into account each period for which resources must be allocated and the manner in which each tenant uses resources, and then coordinates allocation of resources across the entire system using the selected allocation method. This makes it possible to improve the efficiency of resource coordination even in a multi-tenant environment.

  • Publication number: 20160259783
    Abstract: Provided is a method for retaining metadata inheritance relationship in an object storage and for interpreting the relationship. A file and directory inheriting metadata of an upper-level directory allocates the UUID of an object corresponding to the inheritance source directory to metadata of an object of a CAS device corresponding to the file and directory as inheritance information. The inheritance information stored in the CAS device is interpreted in a metadata conversion apparatus (see FIG. 1).

  • Patent number: 9317519
    Abstract: A storage system 103 carries out first and second de-duplication processes in response to receiving a write request from a client. First, a determination is made as to whether a write target data item overlaps with any of the stored data items of a part of a stored data item group, which is a user data item group stored in a storage device 209, and if so, the write target data item is prevented from being stored in the storage device. Second, a determination is made as to whether a target stored data item, which is not finished being evaluated as to whether it overlaps with the stored data item in the first de-duplication process, overlaps with another stored data item, and if so, the target stored data item or the same data item overlapping with the target stored data item is deleted from the storage device 209.

  • Publication number: 20150356108
    Abstract: The present invention is provided to suppress input and output requests to a storage apparatus when a plurality of cloned files has been created based on one shared file. A storage system comprises a plurality of clone-use cache areas 304 corresponding to the cloned files, and a shared cache area 305 corresponding to a shared file. When a read request for any of the cloned files has been received, a prescribed clone-use cache area, from among the plurality of clone-use cache areas, that corresponds to the read-target cloned file is searched for the read-target data, and when determination is made that the read-target data does not exist in the prescribed clone-use cache area, the shared cache area 305 is searched for the read-target data.

  • Patent number: 9116913
    Abstract: A file storage performs control to create a virtual parent file having an identifier capable of uniquely identifying a parent file among storage systems and volumes, and to acquire block layout information of the parent file using said identifier. The file storage creates a virtual parent file in the volume in which the clone file is created, and sets the file as a virtual parent file of the clone file so as to enable creation of a clone file of a parent file that exists in a different volume or a different storage system. Moreover, by combining creating the virtual parent file and switching the identifier of the parent file which is pointed by the virtual parent file, migration of clone files and parent files astride storage systems and volumes is enabled.

  • Patent number: 9015526
    Abstract: A NAS device providing a snapshot function for executing CoW processing in multiple successive block units is provided, wherein upon restoring a file saved in a file system sharing from a snapshot, the speed for restoring files is enhanced by restoring only data blocks that have been changed within the data blocks constituting a file, to thereby reduce the amount of data being restored and cut down CoW processing. Upon restoring a file stored in file system sharing from a snapshot file, data blocks storing different data between the restore source file and the restore destination file are specified based on a differential map table and a differential block table, and only the specified data blocks are restored. Further, upon restoring data from a file other than the snapshot, the data blocks constituting the restore source file and the restore destination file are compared, and only the data blocks storing different data are restored.
