20080235300 | DATA MIGRATION PROCESSING DEVICE - A migration target comprising one or more objects is migrated to a migration-destination file server, which is the file server specified as the migration destination, and object correspondence management information, which is information showing the corresponding relationship between respective migration-source object IDs for identifying in a migration source respective objects included in the migration target, and respective migration-destination object IDs for identifying these respective objects in the migration-destination file server, is created in the migration-destination file server. | 09-25-2008 |
20080235350 | ROOT NODE FOR FILE LEVEL VIRTUALIZATION - A root node creates and issues an object ID comprising share information designating a share unit, which is a logical public unit. The share unit is a logical public unit comprising no less than two objects. Transfer control information in which share information is associated with device information showing a device for managing this share unit, is prepared for each share unit. The root node receives request data, which has an object ID comprising share information, specifies device information corresponding to the share information in this object ID from the transfer control information, and transfers the request data to the device indicated in this device information. | 09-25-2008 |
20100274825 | DATA MIGRATION SYSTEM AND DATA MIGRATION METHOD - 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. | 10-28-2010 |
20120005193 | FILE-SHARING SYSTEM AND METHOD FOR PROCESSING FILES, AND PROGRAM - 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. | 01-05-2012 |
20120005440 | STORAGE SUBSYSTEM AND ITS CONTROL METHOD - 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. | 01-05-2012 |
20120265836 | FILE SHARING SYSTEM AND FILE SHARING METHOD - In a computer system according to an embodiment of the present invention, a first slave server includes copy management information associating a master file system identifier with an identifier of a slave server including a copy of the master file system identified by the master file system identifier. The first slave server acquires a copy of a part of a master file system. The copy includes a stub-state object (file or directory). The first slave server searches the copy management information for a slave server to be queried regarding information for materializing the stub-state object. If the slave server to be queried includes the information for materialization, the first slave server materializes the stub-state object using the information for materialization acquired from the queried slave server. | 10-18-2012 |
20120311002 | COMPUTER AND DATA MANAGEMENT METHOD BY THE COMPUTER - The client computer which transmits an access request specifying an object existing in the first file system and the second computer which accesses the second file system are connected to the first computer which accesses the first file system. The second file system includes a shared directory. A specific object which is an object complying with the path name including the name determined in accordance with the type of the second computer is stored in the shared directory. The controller mounts the shared directory to the first file system. The controller creates a link which comprises a name determined in accordance with a certain naming regulation independent of the type of the computer and corresponds to the specific object in the first file system. | 12-06-2012 |
20120311004 | FILE-SHARING SYSTEM AND METHOD FOR PROCESSING FILES, AND PROGRAM - 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.

20130144921 | ROOT NODE FOR FILE LEVEL VIRTUALIZATION - Root node arrangements configured to carry out file level virtualization for logically providing a plurality of share units that can be shared among file systems of the root node or other one or more root nodes, to a client. | 06-06-2013 |
20140358859 | FILE SHARING SYSTEM AND FILE SHARING METHOD - In a computer system according to an embodiment of the present invention, a first slave server includes copy management information associating a master file system identifier with an identifier of a slave server including a copy of the master file system identified by the master file system identifier.
