Abstract: When computers and virtual machines operating in the computers both attempt to allocate a cache regarding the data in a secondary storage device to respective primary storage devices, identical data is prevented from being stored independently in multiple computers or virtual machines. An integrated cache management function in the computer arbitrates which computer or virtual machine should cache the data of the secondary storage device, and when the computer or the virtual machine executes input/output of data of the secondary storage device, the computer inquires the integrated cache management function, based on which the integrated cache management function retains the cache only in a single computer, and instructs the other computers to delete the cache. Thus, it is possible to prevent identical data from being cached in a duplicated manner in multiple locations of the primary storage device, and enables efficient capacity usage of the primary storage device.

Abstract: A customer inputs a question sentence indicating a problem that the customer needs to resolve, to an automatic question answering system, and the system answers the question sentence. A history of the conversation is recorded in the system as conversation history data. When the system fails to give a suitable answer in a question-and-answer session, the system escalates the question to a support representative. In such a case, the question sentences and an answer sentence given by the support representative to resolve the problem are added to question-answer pair data as new question-answer pairs. The accuracy of automatic question answering is thus enhanced.

Abstract: An example of storage system obtains a reference request of a reference request data block that is included in the content and is stored in the medium area. The storage system determines a number of gaps among addresses, in the medium area, of a plurality of data blocks continuous in the content including the reference request data block. The storage system determines, based on the number of gaps, whether or not defrag based on the plurality of data blocks is valid. The storage system writes, when the defrag is determined to be valid, the plurality of data blocks read from the medium area to the memory area, into continuous address areas of the medium area.

Abstract: When a second storage device in a second site receives an update notification regarding a first element updated according to a write request from a first host, from a first storage device in a first site, for a second element specified on the basis of the update notification, the second storage device manages data of the first element corresponding to the second element as latest data. The first storage device provides a first volume capable of including a plurality of first elements. The second storage device provides a second volume capable of including a plurality of second elements corresponding to the plurality of first elements. When the second storage device receives a read request from a second host, the second storage device determines whether or not data of the first element corresponding to a read source second element (second element specified from the read request) is the latest data. When a determination result is true, the second storage device acquires the latest data from the first storage device and returns the latest data to the second host.

Abstract: When a part already transmitted to an object storage is updated by a file system management section while a plurality of parts are being transmitted to the object storage, a file transfer section requests the object storage to generate a temporary object that is a temporarily generated object containing the transmitted and updated part by combining the parts transmitted before update, re-splits a file into a plurality of parts so that the transmitted and updated data and not-transmitted data are handled as parts different from transmitted and not-updated data, and transmits the part containing the transmitted and updated data or the part containing the not-transmitted data to the object storage.

Abstract: A method switches file server from old file server to new file server which are coupled via a backend network and provides data synchronization. The old file server and new file server are coupled with one or more host computers via a frontend network to direct input/output (I/O) requests from the one or more host computers. The method comprises creating stub files in the new file server, the stub files including stub information indicating location of data in the old file server; switching I/O requests directed to old file server to I/O requests directed to the new file server; checking whether the new file server has any stub files; and, if the new file server has one or more stub files, recalling data corresponding to the one or more stub files from the old file server according to the stub information to replace the one or more stub files.

Abstract: Information regarding an API parameter of a target device is collected from the outside as a manual and knowledge, a description regarding a device configuration, a main parameter, and a specific parameter for which a value is to be set is extracted from the collected manual and knowledge, and a classification axis is created based on the device configuration and the main parameter included in the extracted description. An API execution log and configuration information are collected from the target device, the collected API execution log is classified according to the classification axis, a setting value of the specific parameter in the API execution log is aggregated for each classification, a most frequent setting value is determined as a default value of the parameter, and when the specific parameter is not set in the higher-level API call, the default value is set to make a lower-level API call.

Abstract: To provide a sentence data management method and a sentence data management system in which sentence data and a provision of a regulation are associated and a risk of legal violation associated with outbound transmission of the sentence data is reduced. A sentence data management system includes a processor configured to convert a word string of a first document described using a first term into a word string described using a third term; convert a word string of an outbound-transmitted second document described using a second term into a word string described using the third term; compare the first document and the second document by using a comparison result between the word string and the word string as a comparison result between the word string and the word string; and check a possibility of violation to the regulation in outbound transmission to determine the outbound transmission of the second document.

Abstract: A distributed storage system includes a plurality of storage nodes including: a storage device for storing data in such a way that the data can be written thereto and read therefrom; a memory in which a software program is recorded; and a CPU for executing the software program. The memory stores group management information in which a group configured with a plurality of storage nodes and the storage nodes that configure the group are associated with each other and recorded. The CPU converts data into a plurality of data blocks so that the data is redundant at a predetermined data protection level, and stores the data blocks into each of a plurality of storage nodes belonging to the same group based on the group management information.
