摘要： A simultaneous failure occurrence degree calculation section calculates a simultaneous failure occurrence degree a value of which becomes smaller with an increase in a difference between numeric values indicative of manufacture date information on a computer which performs a process on the basis of a duplication combination management program. A combination pattern generation section then combines two of a plurality of storage apparatus and generates a plurality of combination patterns. A simultaneous failure occurrence degree adding section then calculates a total of simultaneous failure occurrence degrees corresponding to combinations of storage apparatus for each of the plurality of combination patterns. A duplication combination pattern determination section then determines that a combination pattern for which the total of simultaneous failure occurrence degrees is the smallest is a duplication combination pattern.

摘要： An allocation control apparatus may access an address table storing addresses of slice areas allocated in a storage area for an entire storage system having a plurality of storage devices and addresses that do not correspond to allocated slice areas. The allocation control apparatus includes a reception unit receiving a request for allocating an arbitrary storage capacity an allocation unit allocating, by referring to the address table, an address that does not correspond to the allocated slice area for at least a part of the requested storage capacity and allocates an address for the slice area to the remaining storage capacity when the reception unit receives the allocation request, and a transmission unit transmitting the result allocated by the allocation unit to a requesting source of the allocation request.

摘要： A storage system having a plurality of storages. The each of the storages include a memory and a processor coupled to the memory. The processor executes a process including transmitting an update request for data which is commonly stored in the plurality of storages according to a predetermined transmission order indicating a path to transfer the update request. The process includes updating data when receiving an update request from another storage. The process includes changing the predetermined transmission order to a transmission order in which one or more storages included in the path are excluded according to the number of times the update request for the data is received.

摘要： Upon receipt of a first key and first data, a control unit exercises control to store second data indicating a second key in association with the first key in a first node and to store the first data in association with the second key in a second node. Upon receipt of an access request that specifies the first key, the control unit detects that data stored in association with the first key is the second data, and accesses the first data stored in the second node on the basis of the second key indicated by the second data.

摘要： A storage apparatus, method and program are provided. The apparatus includes a management information storing unit that stores management information which defines storage nodes to allocate primary data used as a destination of access and secondary data used as a backup. The apparatus also includes data allocation unit that divides storage nodes 5 into groups, and assigns data allocation destination so that the data allocation destination of the primary data and the data allocation destination of the secondary data with the same content as the primary data are not in the same group. The apparatus also includes an operation mode switching unit that replaces the role of primary data assigned to the storage node which belongs to the group subject to suspension with that of the secondary data that corresponds to the primary data.
