    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: An allocation control apparatus allocates duplicate logical volume divided areas to virtual storage areas that do not have data storage area in the physical storage area. The apparatus associates identification information of the allocated virtual storage areas, of the duplicate logical volume divided areas, and of duplication source logical volume divided areas to be set in the management information. The apparatus detects, upon a data writing request, based on the management information, the unallocated real storage area in the logical volume divided area. The apparatus reallocates the real storage area to the duplicate logical volume divided area to update the management information. The apparatus identifies, based on the management information, the real storage area allocated to the duplication source logical volume divided area corresponding to the duplicate logical volume divided area. The apparatus copies data stored in the real storage area to the real storage area.

    摘要: In a computer for executing processing based on a storage management program, a management information storing unit designates, from the data blocks having the same content, main-data used as an access destination and sub-data used as a backup, and stores management information that registers storage nodes as allocation destinations of the respective main-data and sub-data; a load information collecting unit continuously collects load information on the storage nodes; a replacement object detecting unit detects a pair of the main-data and the sub-data having the same content and having a predetermined condition such that a load difference between the allocation destination of the main-data and that of the sub-data exceeds a predetermined allowable value; and a management information updating unit replaces roles of the main-data and the sub-data between the detected pair of data blocks.

    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.
