  • Publication number: 20150106363
    Abstract: When plural processing programs for generating post-processing data which is a source of services to be provided are present, a relationship between post-processing data and a data group which is a source of the post-processing data is managed. The processing units acquire pre-processing data, execute given processing, and generate post-processing data as a result of the processing. At an opportunity to acquire the pre-processing data, a process ID indicative of ordering of the acquisition, and not updated before and after the given processing is allocated to acquired pre-processing data. The generated post-processing data is stored, and in extracting the post-processing data satisfying the given data search condition, the post-processing data having a process ID equal to or before the process ID that is latest in the post-processing data and oldest among the respective processing units is extracted from the post-processing data that satisfies the data search condition.

  • Patent number: 8862812
    Abstract: A first storage system includes a first storage unit to provide storage volumes, a first storage controller, and a first memory to store a first control program to process an input/output request received by the first storage system. A second storage system includes a second storage unit to provide storage volumes, a second storage controller, and a second memory to store a second control program to process an input/output request received by the second storage system. Each of the first and second storage systems is configured to present the storage volumes of the other storage system to the host computer, so that the host computer can access the storage volumes of each of the first and second storage systems via one of the first and second storage systems if the host computer is unable to access the storage volumes via the other storage system.

  • Patent number: 8819205
    Abstract: Provided are a content transfer system, a content transfer method, and a home server capable of backing up all backup target contents without having to transfer all backup target contents. This content transfer system includes a home storage and an online storage. The home storage transfers identifying information of a backup target content to the online storage and requests the online storage to determine the existence of a content that is identical to the backup target content upon requesting the online storage to back up the backup target content, transfers metadata to the online storage when an identical content exists in the online storage, and transfers the backup target content to the online storage in all other cases.

  • Patent number: 8819796
    Abstract: Security is improved as compared to the security of conventional authentication systems, only by requesting a user to perform operations involving the same number of operations as that of the conventional authentication systems. When login information is registered, an authentication system (1, 1A) accepts registration of a type of a login image that composes an authentication button for initiating user authentication. When displaying an authentication page that is used for user authentication, the authentication system (1, 1A) displays buttons including the authentication button composed of the login image and dummy buttons composed of other images. The authentication system (1, 1A) performs user authentication in a case in which an operation button selected by the user is the authentication button.

  • Patent number: 8706714
    Abstract: The performance of the analysis system is deteriorated because file content extraction processing is performed in the file aggregation server and in the analysis server and further because annotation data creation is performed in the file aggregation server. Therefore, the present invention solves the problem by providing a file aggregation server classifying files into analysis target contents, non analysis target contents, and content matched data, and providing only the analysis target contents to the analysis server. Since this method enables the analysis server to acquire the analysis target contents directly from the file aggregation server, the processing of extracting contents from the files becomes unnecessary, and the throughput of the entire analysis system is improved.

  • Patent number: 8700567
    Abstract: The present invention enables a unified way of accessing files generated by application programs configured to store contents in files in different formats, without using a conversion program. A database for holding correspondence between an identifier of a content and a storage position of the content is generated based on a backup catalog generated by a backup server, and contents are accessed by using this database. Contents generated by a plurality of different application programs are accessed in a unified way using a single name space.

  • Patent number: 8635280
    Abstract: In a service system having plural servers and storage systems connected via a network, a storage library is installed on all servers on which applications are running. All applications can use the storage library to create new data, read data, and update data in different types of backend storage systems. In one embodiment, the storage library holds a list of all storage systems which can be used for storing data, and manages capabilities of the storage systems, such as data replication and data integrity checking. The storage library is arranged to create a write profile for each created data in order to indicate how the data is being managed. A storage system and the storage library are thus able to avoid performing unnecessary data management (for example, redundant replication) by checking whether such data management is or has been performed by the storage library or by the storage system by referring to the write profile.

  • Patent number: 8521985
    Abstract: There is provided a storage subsystem having a virtual volume and a page volume which has a page physical area allocated to the virtual volume. The storage subsystem divides an address space of the virtual volume into a plurality of pages, classifies each of the pages into one of a plurality of states including at least a first state and a second state, and further divide a page which is classified into the second state into a plurality of segments to managed the page classified into the second state. The first state is a state in which a page physical area is allocated to the page from the page volume, and the write data is stored in the page physical area. The second state is a state in which the predetermined pattern data and the segment are managed, in the memory, by correlating with each other.
