| 20080263222 | COMPUTER SYSTEM, ROOT NODE, AND LOG MANAGEMENT METHOD FOR ACCESS PATH CONVERSION - A computer system including a storage system, a host computer system, a path configuration unit that associates a local path with a global path, an access path conversion unit that converts a global path into a local path associated, by the path configuration unit, with the global path used in the file access, and forwards the converted file access to the storage system, an access log reception unit that receives an access log from the storage system, an access log conversion unit that converts the local path used in the access log received by the access log reception unit, into a global path associated, by the path configuration unit, with the local path used in the received access log, and an access log display unit that displays the converted access log. | 10-23-2008 |
| 20080294704 | INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD - Providing an information processing apparatus and information processing method that prevent the occurrence of inconsistencies between restored files and other files, thereby improving ease of use. When restoring a backup virtual tree, the owner of each file and directory belonging to the backup virtual tree is identified; and when it is found, based on the identification result, that the owner of any of the files or directories is not a target user and the update time and/or version of the backup file or directory is older than that of the corresponding present file or directory, the backup file or directory is restored back into a special directory accessible for the target user with the tree structure of the original virtual tree intact. | 11-27-2008 |
| 20080306917 | FILE SERVER FOR PERFORMING CACHE PREFETCHING IN COOPERATION WITH SEARCH AP - Provided is a control computer coupled to a storage apparatus for storing a plurality of information resources and a search computer for receiving a search request containing a search condition and transmitting information resource list information containing at least one piece of information regarding an information resource corresponding to the search condition as a search result, the control computer includes a cache memory for storing at least one of the plurality of information resources, in which the control computer is configured to: receive the information resource list information from the search computer; calculate cache priority for each of the information resources based on the received information resource list information; decide at least one information resource to be stored in the cache memory based on the calculated cache priority; and store the decided at least one information resource in the cache memory. | 12-11-2008 |
| 20090150455 | File server, file server log management system and file server log management method - The present invention provides a log management system which is devised so that improper behavior by managers with regard to the log information can easily be discovered. Virtual OS are respectively installed for respective users in a file server that can also be constructed as an NAS device. These virtual OS function as virtual NAS. The virtual OS and manager OS can exchange information relating to log information via an information exchange part constructed as a kernel. The log information produced in the virtual OS is transmitted to a first log management device via a first communications network, and is also transmitted to a second log management device via a second communications network. The respective networks are separated. As a result of the same log information being managed by multiplex management using separate management devices, it can be detected whether or not there has been any improper behavior with respect to the log information. | 06-11-2009 |
| 20090240899 | Storage device and method of controlling same - A storage device having a volume for storing data sent from a host computer and transferring the data stored in the volume to a sub storage device via a network, comprises: a retrieval unit for retrieving a snapshot retaining change data generated in the volume during a time period between a given time and another given time, and a maximum transfer size of the network between the storage device and the sub storage device; and a control unit for controlling so as to store data exceeding a maximum transfer size in the area of another snapshot, when the size of a created snapshot exceeds the maximum transfer size. | 09-24-2009 |
| 20100070724 | Storage system and method for operating storage system - In acquiring a snapshot, when data in a P-VOL is updated, it is determined whether the same data as target data to be stored in a certain second storage area specified by a certain second address of a D-VOL is already stored in a different second storage area specified by a different second address of the D-VOL, the target data being the differential data generated by the update. When the same data as the target data is stored, the target data is not newly stored in the D-VOL, and the different second address, specifying the different second storage area where the same data is stored, is registered in a snapshot management table (CoW table), in association with a certain first address specifying a certain first storage area where the data from which the target data has been generated is stored. | 03-18-2010 |
| 20100262637 | FILE CONTROL SYSTEM AND FILE CONTROL COMPUTER FOR USE IN SAID SYSTEM - A situation where, even though a file system set with an additional function has been expanded, the additional function is unable to operate is prevented from occurring. Provided are a file control computer and its system having a main computer including a file system for managing reading and writing of data between the client computer and the storage device, a control circuit for controlling the file system, and a memory circuit for storing management information of the file system. The memory circuit stores setting information which is set with an additional function that is set to the file system, and a condition necessary for operating the additional function. Upon expanding the file system based on the management information, the control circuit determines a status of fulfillment of the condition in the expanded file system, and outputs warning information if the determination result denies fulfillment of the condition. | 10-14-2010 |
| 20110035409 | HIERARCHICAL STORAGE SYSTEM AND COPY CONTROL METHOD OF FILE FOR HIERARCHICAL STORAGE SYSTEM - An interface for controlling an inhibition of a recall is prepared for an application, and a judgment of necessity of a recall is informed of to a hierarchical storage before the application executes an access to a file. | 02-10-2011 |
