    摘要: In a cluster system: a heartbeat transmission unit in a service provision node transmits to a monitoring node a heartbeat packet which contains interval information indicating an interval greater than normal intervals at which normal heartbeat packets are transmitted, when an execution unit in the service provision node receives a stop command. Thereafter, when software realizing the execution unit is updated and the execution unit is restarted, the heartbeat transmission unit periodically transmits the normal heartbeat packets to the monitoring node at the normal intervals, where the normal heartbeat packets contain interval information indicating the normal intervals. A heartbeat monitoring unit in the monitoring node determines that the execution unit is in operation, while the monitoring node receives heartbeat packets at intervals indicated by the interval information stored in the monitoring node and updated with received interval information.

    摘要: In a distributed storage system, client terminals make access to virtual storage areas provided as logical segments of a storage volume. Those logical segments are associated with physical segments that serve as real data storage areas. A management data storage unit stores management data describing the association between such logical segments and physical segments. Upon receipt of access requests directed to a specific access range, a segment identification unit consults the management data to identify logical segments in the specified access range and their associated physical segments. A remapping unit subdivides the identified logical segments and physical segments into logical sub-segments and physical sub-segments, respectively, and remaps the logical sub-segments to the physical sub-segments according to a predetermined remapping algorithm. A data access unit executes the access requests based on the remapped logical sub-segments and physical sub-segments.

    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.
