    摘要: The present invention relates to a system capable of carrying out efficient and stable system operation control even if a usage rate of the entire system varies under a situation in which the characteristics of storage units, such as maximum available total capacity and speed performance, are largely different from each other. Therefore, the system according to the present invention is composed of a monitor unit for monitoring information on a total volume of data stored in each of the storage units or in all the storage units, an index value calculating unit for calculating an index value on the basis of the monitor result and a location unit for distributively locating or relocating logical storage areas in physical storage areas on a plurality of storage units on the basis of the calculated index value.

    摘要: A storage system is disclosed that stores data across plural storage devices. The storage system includes plural modules. Each of the modules includes a storage device including a data storage section that has plural slice areas to store data elements one in each, and a control-information storage section that stores control information of the plural slice areas, a communications-function section having a function of sending and receiving the data elements stored in the slice areas in the data storage section. The modules communicate with each other to replicate the data element stored in the slice area into an unused slice area in another module so as to have data redundancy.

    摘要: In a storage system, a plurality of RAID devices are connected to a network, and data is multiplexed to primary data and secondary data by being mirrored among the RAID devices. When a failure of a disk device that can be recovered within the devices owing to the RAID configuration occurs, data of a disk device corresponding to the failed disk device is requested to a RAID device that is its mirror target and the transferred data is written to a spare disk device for the recovery. At the time of the data recovery, an access right to a group of disk devices constituting RAID and an access right to individual disk devices are exclusively controlled with respect to an input and output of the primary data.

    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: 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.
