    摘要: A data management apparatus sends specific data and key information corresponding to the specific data to another apparatus, when executing a process to change a storage destination of the specific data in which the hash value obtained by applying a predetermined hash function to corresponding key information belongs to a certain range, from the data management apparatus to the other apparatus, and sends the identification information of the other apparatus stored in correspondence with the certain range to a request source of an operation request, when the operation request with respect to data corresponding to key information is received after the process.

    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: An internode put requesting unit detects a time-out with respect to a put request issued to the next node in the order of a multiplexing chain and notifies a put/get executing unit of the time-out. The put/get executing unit sends an error to the previous node in the order of the multiplexing chain or a client and instructs a put-failed-data synchronizing unit to synchronize data failed to be put, and the put-failed-data synchronizing unit performs a synchronization process. A primary makes other put requests wait until completion of the synchronization process. Furthermore, when having received the error, the client issues a get request to the tail end of the multiplexing chain.

    摘要: A storage device being one of a plurality of storage devices storing data includes a memory and a processor coupled to the memory. The processor executes determining, when having received a new request and a new priority information during a preparation for an execution of another update processing, whether a new priority indicated by the new priority information is higher than a priority of the update processing in the preparation. The process including canceling the update processing in the preparation when having determines at the determining that the new priority is higher than the priority of the update processing in the preparation. The process includes forwarding the new request and the new priority information to another storage device when having determined at the determining that the new priority is higher than the priority of the update processing in the preparation.
