    摘要: Storage nodes participating in the distributed storage system are divided into groups beforehand. A data replica creation unit operates so that a replica is created on each of the nodes participating in the distributed storage system on a hash ring. A unit that specifies an operating state of the system determines the number of data replicas for each group. The data replica creation unit traverses the hash ring and creates one or more replicas until it is determined that the number of replicas for each group is reached.

    摘要: Disclosed is a system including a storage that includes a high-speed response past data protection unit that holds high-speed response past data, a continuous data protection unit that performs continuous data protection, a data synthesis unit that synthesizes data using the data in the high-speed response past data protection unit and data in the continuous data protection unit, and a past data updating unit that creates data corresponding to a predetermined trigger in advance. The past data updating unit restores the data corresponding to the predetermined trigger in advance. The data synthesis unit returns the high-speed response past data stored and held in the high-speed response past data protection unit. For a request to access data other than the one at the predetermined trigger, the data synthesis unit returns the data synthesized.

    摘要: Access destination determination means determines a read destination and/or a write destination of specified data from nodes corresponding to the data and stored in data store destination storage means. Access probability calculation means calculates an access probability based on a history of accesses to the data, and stores the calculated access probability in access probability storage means. When no node corresponding to the specified data is stored in the data store destination storage means, access probability estimation means estimates an access probability of the data based on access probabilities stored in the access probability storage means, and the access destination determination means determines a write destination of the data based on the estimated access probability.

    摘要: A distributed system includes: a plurality of ordinary nodes provided with reduced-power states having different times of recovery to a normal operating state; and a management node for assigning a job to an ordinary node for carrying out the job. The management node has: node select means for selecting an ordinary node from ordinary nodes each put in one of the reduced-power states, assigning a job to the selected ordinary node and driving the selected ordinary node to carry out the assigned job; and node control means for executing control to restore an ordinary node selected by the node select means to the normal operating state. The node select means selects an ordinary node from the ordinary nodes each put in one of the reduced-power states having different times of recovery to the normal operating state in accordance with an ordinary-node order starting with an ordinary node existing in a reduced-power state and having a short time of recovery to the normal operating state.

    摘要: The index update unit analyses the information stored in a document repository to create an index for search and stores the index in a time-series divisional index storage unit and creates, from an ACL repository, an access control entry ACE in association with the index for search, which is correlation of information to be searched with access right of at least a group to which the user belongs. The ACL cache generation unit creates ACL cache data that correlates the user with access right to the information to be searched, from the ACE, and registers the ACL cache data created in an ACL cache. A search processing unit searches for an index for search in response to a request for search from said user. In case the ACL cache data correlating the user with the index for search is registered in the ACL cache, the search processing unit_takes, from among the information searched, the information, reference to which is allowed for the user as a search result, based on information in the ACL cache.
