    摘要: An access method includes: obtaining, by a computer, a result of monitoring a busy rate and a number of access operations per unit time of a storage device, the storage device having a first storage area and a second storage area; calculating a characteristic of correlation between the busy rate and the number of access operations per unit time based on the result; calculating a second number of access operations per unit time based on the characteristic of the correlation such that a sum of a first busy rate corresponding to a first number of access operations per unit time and a second busy rate corresponding to a second number of access operations per unit time becomes equal to or lower than a given busy rate; and controlling a number of operations to access the second storage area per unit time based on the second number of access operations.

    摘要: A file server has a conversion table that stores therein, in a corresponding manner, logical addresses specified by a higher-level layer and physical addresses specified by a disk driver that are address information indicative of a storage area in a disk device. The file server accesses the disk device with a storage area indicated by a physical address as an access destination and counts up the number of access requests to each storage area in a given period of time for each of the logical addresses. The file server then updates the conversion table such that the physical addresses are lined up in a descending order of the logical addresses of a higher number of the access requests counted. Thereafter, the file server changes storage areas of data stored in the storage device based on the conversion table updated.

    摘要: An information processing apparatus includes a first storage unit and a processor. The first storage unit includes a first storage area. The processor receives a first request to write first data into the first storage area. The processor requests an external apparatus to write the first data into a second storage area in a second storage unit included in the external apparatus. The processor determines whether a first response has been received from the external apparatus. The first response indicates that the first data has been written into the second storage area. The processor writes the first data into the first storage area when the first response has been received. The processor requests, without writing the first data into the first storage area, the external apparatus to write second data stored in the first storage area into the second storage area when the first response has not been received.

    摘要: A computer-readable recording medium stores a program that causes a computer to execute a writing control process that includes receiving a writing request to write a first data to a first storage apparatus; determining a second data from among a series of data and based on a writing sequence of the series of data written to the computer and a count of storage areas at a second storage apparatus that sequentially selects from among the storage areas when data is received, a storage area to be over written by the received data, where the second data is written to the first storage apparatus and is identical to data that is stored in the storage area to be selected next at the second storage apparatus; and transmitting copy data of the first data to the second storage apparatus, when the second data has been written to the first storage apparatus.

    摘要: A parity-data generating unit generates, in response to a write request containing update data, updated parity data in the parity group to which the update data belongs. A time-series-information generating unit generates time-series information indicating an anteroposterior relationship during writing between the update data and existing data stored in the unit storage area to which the update data is to be written. A time-series-information adding unit adds the time-series information, generated in response to the write request, to the update data as certification time-series information and that adds comparison time-series information to the updated parity data in association with the update data, the comparison time-series information having the same value as the certification time-series information. A writing unit distributes and writes, to the multiple storage devices, the update data to which the certification time-series information is added and the updated parity data to which the comparison time-series information is added.
