摘要： A storage apparatus includes: an associating unit that associates a first memory area in which data to be copied are stored and a second memory area of a destination storage apparatus to which the data are copied; a detecting unit that detects a start or an end of copying the data from the first memory area to the second memory area associated by the associating unit; and an access control unit that controls access to the first memory area and the second memory area based on a result of detection performed by the detecting unit.

摘要： A storage system includes a primary-side storage device and a secondary-side storage device. The primary-side storage device includes a first storage unit that functions as: a primary-side reserving unit to reserve a primary-side storage area in the first storage unit; a request unit to request the secondary-side storage device to reserve a secondary-side storage area; a checking unit to receive identifying information of the reserved secondary-side storage area; a management storage unit to store the identifying information of the secondary-side storage area in the way of being associated with the primary-side storage area; and a transfer unit to transfer data stored in the primary-side storage area to the secondary-side storage area. The secondary-side storage device includes a second storage unit that functions as: a request accepting unit to accept a request for reserving the secondary-side storage area from the primary-side storage device; a secondary-side reserving unit to reserve the secondary-side storage area in the second storage unit in response to the request; and a report unit to report the identifying information of the reserved secondary-side storage area to the primary-side storage device.

摘要： A storage device includes a accepting unit that accepts a replication request that concerns a replication storage area for target data and that is from a requesting server that is among a plurality of servers; a first determining unit that, if a replication request is accepted, determines whether an identifier of the requesting server is included in a first table that stores identifiers of the servers that satisfy a first condition; a second determining unit that, if a replication request is accepted, determines whether the identifier of the requesting server is included in a second table that stores identifiers of the servers that satisfy a second condition; and an executing unit that executes a replication process of replicating the target data to the replication storage area, if the first or the second determining unit determines that the identifier is included.
