摘要： The disclosed method includes obtaining a result concerning a busy rate and the number of accesses per unit time for a storage device including first and second storage areas; determining, from the result, whether an event that a first indicator value for the busy rate is reset occurs; when the event occurred, notifying a controller that makes the number of accesses for the second storage area not greater than the notified number of accesses of the first number of accesses less than the second number of accesses, which was notified immediately before; obtaining another result; updating the first indicator value based on another result; calculating the third number of accesses so that a sum of busy rates corresponding to the third number of accesses and corresponding to the designated number of accesses becomes equal to the updated first indicator value; and notifying the controller of the third number of accesses.

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： 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.

The group-by processing system includes a unit for storing records; a unit for storing pointers to the records in the unit for storing records at positions, each of which corresponds to a hash function value calculated using the key value of the pointed record; a unit for outputting the records pointed to by the pointers in the unit for storing pointers to secondary storage device, given the hash function values; and a unit for reading a list of output hashed records, sorting the records by key value, and performing a group-by operation on the sorted records. The system also includes a combination generation unit for outputting a combination of two or more items satisfying a combination generation restriction condition; an occurrence count unit for counting occurrences of the combinations; a combination selection unit for selecting the combination which satisfies the given condition of the number of occurrences; and a restriction condition generation unit for assigning the restriction condition to the combination generation unit according to the selection result. The combinations of items can be counted efficiently by performing a high-speed group-by operation.
