A storage control apparatus includes a plurality of MBFs for managing pieces of data stored in a storage by storage region, caches some of the MBFs on a RAM, and determines the presence or absence of redundancy on a basis of the MBFs on the RAM alone. The storage control apparatus performs redundancy elimination on the pieces of data already stored in the storage on the basis of how the MBFs are used such that the contents of a hash log for an MBF higher in frequency of use are maintained.

Storage control apparatus and storage control method

A storage control apparatus includes a memory, and a processor. The memory is configured to retain associative relation information for managing an associative relation between a hash value associated with a first address being inputted and a second address as an address of the storage device, filter information containing Bloom filters, and overlap count management information. The processor executes a process that causes the storage control apparatus to perform first storing the storage target data in the storage device without being registered in the filter information, second storing the storage target data in the storage device as well as registering the storage target data in the filter information, performing neither registering the storage target data in the filter information nor storing the storage target data in the storage device and deleting deletable data from the storage device.

A deduplicate device includes: a first through N-th (N&#x2267;3) bloom filters; a counting unit that performs a process of judging whether information indicating that a duplicate data of a storing-target data exists in a storage device is registered in each bloom filter sequentially until an unregistered bloom filter in which the information is not registered is found or that the information is registered in the N-th bloom filter is found, and registers, when the unregistered bloom filter is found, the information indicating that the duplicate data exists into the unregistered bloom filter; and a deduplicating unit that stores the storing-target data in the storage device when the counting unit finds the unregistered bloom filter, and stores index information relating the duplicate data in the storage device with the storing-target data when the counting unit finds that the information is registered in the N-th bloom filter.

Deduplication device and deduplication method

A computer-readable recording medium stores a program that causes a computer to execute a writing control process that includes receiving a writing request to write a first data to a first storage apparatus; determining a second data from among a series of data and based on a writing sequence of the series of data written to the computer and a count of storage areas at a second storage apparatus that sequentially selects from among the storage areas when data is received, a storage area to be over written by the received data, where the second data is written to the first storage apparatus and is identical to data that is stored in the storage area to be selected next at the second storage apparatus; and transmitting copy data of the first data to the second storage apparatus, when the second data has been written to the first storage apparatus.

Access method, computer and recording medium

A data management apparatus sends specific data and key information corresponding to the specific data to another apparatus, when executing a process to change a storage destination of the specific data in which the hash value obtained by applying a predetermined hash function to corresponding key information belongs to a certain range, from the data management apparatus to the other apparatus, and sends the identification information of the other apparatus stored in correspondence with the certain range to a request source of an operation request, when the operation request with respect to data corresponding to key information is received after the process.

Data management apparatus and system

An information processing apparatus includes a first storage unit and a processor. The first storage unit includes a first storage area. The processor receives a first request to write first data into the first storage area. The processor requests an external apparatus to write the first data into a second storage area in a second storage unit included in the external apparatus. The processor determines whether a first response has been received from the external apparatus. The first response indicates that the first data has been written into the second storage area. The processor writes the first data into the first storage area when the first response has been received. The processor requests, without writing the first data into the first storage area, the external apparatus to write second data stored in the first storage area into the second storage area when the first response has not been received.

Information processing apparatus and storage control method

Nodes respectively store a multilayer transposed Bloom filter. A client selects a node Nfrom among the group of nodes and transmits a search request to the node N. Upon receiving a reply from the node N, the client determines whether the received search result indicates 'positive'. If the search result is not positive, the client selects in order of node number, a node Nand transmits a search request to the node N. Upon receiving a reply from the node N, the client determines whether the received search result indicates 'positive'. Upon determining that the search result is positive, the client outputs the search result and ends the search notification process.
