    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.

    摘要: In a computer which executes an access control program, an authentication information storage unit stores authentication information. A logical volume acquiring unit acquires a logical volume associating data with storage nodes storing the data, from a predetermined database. In response to an access request to access data, a data access unit identifies a storage node to be accessed, based on the logical volume, and sends the authentication information and a command corresponding to the access request to the identified storage node.
