摘要： If a failure occurs in physical resources constituting a virtual volume, a management server device is notified of information required by a user. A computer system includes a server device for managing a plurality of virtual volumes, a storage apparatus having a storage unit equipped with a plurality of storage devices, and a controller for controlling data input to, or output from, the storage unit, a management server device which is an access target of a user terminal, and an event management device for managing an event(s) generated by the server device or the storage apparatus, wherein when the event management device receives the event, it judges the content of the event and identifies a virtual volume to be affected by the event; and if a service level that should be satisfied by the identified virtual volume is defined for the identified virtual volume, the event management device identifies, based on the content of the received event, whether an incident in violation of the service level has occurred or not, and then notifies the management server device of the identified content as an event based on an event filter.

摘要： A file, for which writing has been reserved, in a file-sharing system can be efficiently read. A check-in file agent is provided in a computer that executes check-in of a file as the file-write reserving processing, a file manager is provided in a file-sharing computer, and a check-out file agent is provided in a computer that executes check-out of a file as the file reading processing. Upon request for check-in of a file, the check-in file agent divides the file into divided files and generates metadata that indicates the order of division of the file, and transmits them to the file-sharing computer for storage therein. Upon request for check-out of the file, the check-out file agent receives the metadata from the file-sharing computer, and based on the metadata, sequentially receives the divided files to generate a file to be checked out.

摘要： To improve performance of a de-duplication process carried out by a storage system. When receiving a write request from a client, the storage system carries out a first de-duplication process, and thereafter carries out a second de-duplication process at an appropriate time. In the first de-duplication process, a determination is made as to whether a write target data item overlaps with any of stored data items of a part of a stored data item group, which is a user data item group stored in a storage device, and the write target data item is prevented from being stored in the storage device, when a result of the determination is positive. In the second de-duplication process, a determination is made as to whether a target stored data item, which is not finished with an evaluation of whether or not it overlaps with the stored data item in the first de-duplication process, overlaps with another stored data item, and the target stored data item or the same data item overlapping with the target stored data item is deleted from the storage device, when a result of the determination is positive.

摘要： A new storage tier is added to a plurality of storage tiers configured in storage areas of a plurality of types of storage devices, whose processing performance is different from each other, without changing its operation form. If a new Tier3 constituting a file system FS4 is added between Tier2 and Tier3, a file server adds a registered generation 1 to a tier number change management table, sets Tier3 as the added file system FS4 in the registered generation 1, manages Tier4 as a file system FS5, which has been changed from the former Tier3, adds a policy corresponding to a policy number 1005 to a migration policy management table, updates only the registered generation from 0 to 1 for policy numbers 1002, 1005, and manages the migration policy management table.

摘要： Provided is a technique capable of efficiently operating files and directories that are stored in storage located in a physically far place from a file server, without causing a network latency. An index creation program is also loaded in a cloud computing environment, and a flag, which indicates whether or not to execute batch processing to a directory that has been migrated to the cloud side, is provided, whereby it becomes possible to collectively execute index creation processing for the migrated directory on the cloud side. More specifically, upon completion of migration of all files under a given directory to the cloud side, a flag, which indicates whether or not to perform batch processing on the cloud side, is validated for the metadata of the directory. Such a batch processing flag can be held for each application such as applications of the index creation processing and the virus check processing.

摘要： The present invention enables creation of a clone file of a parent file stored in a different volume or a different storage system, and enables migration of a parent file and a clone file among volumes and storage systems. 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： 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.
