摘要： The prior art information system could not migrate a file in a file sharing system provided by a file storage to a plurality of cloud storages having different forms of connection and different properties, and therefore, could not manage the files via a single Stub information. The present invention provides a data mover program in a file storage to select one or more migration destination cloud storages based on a migration policy, a connection information table of cloud storages and a property information table of cloud storages. Then, a Stub information of the migrated file is created, and an identification information of the file in the cloud storage is stored in a file information table. When access occurs from a client to a file storage, the data mover program downloads a file from the cloud storage stored in the file information table corresponding to the Stub information and provides the file to the client.
摘要翻译：现有技术的信息系统不能将由文件存储器提供的文件共享系统中的文件迁移到具有不同形式的连接和不同属性的多个云存储器中，因此无法通过单个存根信息来管理文件。本发明提供一种文件存储器中的数据移动器程序，用于基于迁移策略选择一个或多个迁移目的地云存储，云存储的连接信息表和云存储的属性信息表。然后，创建迁移文件的存根信息，将云存储中的文件的识别信息存储在文件信息表中。当从客户端到文件存储进行访问时，数据移动器程序从与存根信息相对应的文件信息表中存储的云存储中下载文件，并将该文件提供给客户端。

摘要： 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.

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 comprises a storage apparatus which includes a processor, storage disks, and a memory storing a page mapping table, a page mapping program, and a page-filename mapping program. A file system manages a file tree of files with filenames. The page mapping table specifies a relationship between data volumes in the storage apparatus and the storage disks and the file system, the data volumes each including pages, each page including segments, each segment including sectors. The file tree has for each storage apparatus a hierarchy of directories and files based on relationships among the data volumes, the pages, and the segments. The page mapping program and the page-filename mapping program are executable by the processor to specify, by page, a location of data contained in the I/O request by referring to the page mapping table and the file tree.

摘要： An aspect of the invention relates to a method of managing data location of plural files in a storage system having a mixed volume which includes plural pages having a fixed page size, the pages belonging to different tiers. The method comprises mapping pages of different tiers to storage devices of different speeds in the storage system, the storage devices including at least a high speed storage device corresponding to a high tier page and a low speed storage device corresponding to a low tier page; and for each file that is a large file which is larger in size than the page size, performing sub-file tiered management on the large file to assign the large file among pages of different tiers according to access characteristics of different portions of the large file by matching the access characteristics of each portion of the large file with a corresponding tier of the assigned page of the mixed volume.
