Abstract: A processor controls a second storage device including a plurality of media that store data stored in a first storage device. The processor calculates a ratio of the size of each of a plurality of data blocks, which are classified according to a plurality of pieces of dimension information in data stored in two or more of the plurality of media, to the amount of data stored in two or more of the plurality of media. The processor determines, based on a calculated ratio, whether a data block is to be duplicated, generates a duplicate of a data block determined to be duplicated, and stores the generated duplicate of the data block into another medium of the plurality of media, except for the two or more media. This can reduce the number of times of changing a medium, and suppress lowering in the capacity efficiency. Dimension information may be an axis of obtaining data.

Abstract: An apparatus determines a similarity of names of a plurality of virtual machines, and divides the plurality of virtual machines into clusters based on a result of the determination such that virtual machines having a value that represents the similarity of the names that is equal to or less than a given threshold are included in a first cluster and virtual machines having a value that represents the similarity of the names that is greater than the given threshold are included in a second cluster. The apparatus places virtual machines included in the first cluster on different host machines.

Abstract: A control unit calculates the expected number of access operations to each recorded data set, and selects one or more recorded data sets as recorded data sets to be relocated, based on the expected number of access operations. The control unit calculates the expected number of access operations to each recorded data set, based on a calculation period and the number of access operations per unit time. The calculation period differs from one recorded data set to another, depending on the next update timing. If the next update timing is earlier than the next relocation timing, the calculation period is a period from the current relocation timing to the next update timing. On the other hand, if the next update timing is later than the next relocation timing, the calculation period is a period from the current relocation timing to the next relocation timing.

Abstract: In controlling a second storage device including a plurality of media that store data stored in a first storage device, a processor calculates a ratio of each of a plurality of data blocks, which are classified according to a plurality of pieces of dimension information in the data stored in two or more of the plurality of media, to the data; determines, based on the calculated ratio, whether the data block is to be duplicated; and generates a duplicate of a data block determined to be duplicated and store the generated duplicate into another medium of the plurality of media except for the two or more media. This can reduce the number of times of changing a medium, suppressing lowering in the capacity efficiency.

Abstract: From unit storage areas each having a certain size in a first storage device, an extraction unit extracts, at certain time intervals, a monitored area formed by consecutive unit storage areas having been accessed at least a predetermined number of times that is greater than zero and being similar to each other in the number of times of access. When detecting movement between the positions of same-sized monitored areas among the extracted monitored areas over time, a prediction unit determines a predicted storage area predicted to be accessed in the storage area of the first storage device on the basis of the direction of the movement between the positions of the same-sized monitored areas, and performs a control operation so that the content of the predicted storage area is copied to a second storage device that provides faster access than the first storage device.

Abstract: A storage control apparatus includes a processor. The processor is configured to detect a dependency relationship between a first data access and a second data access made after passage of a delay time from the first data access. The first data access is made to a first storage area in a first storage device. The second data access is made to a second storage area in the first storage device. The processor is configured to transfer, when a current data access is made to the first storage area in a state in which the dependency relationship is detected, data in the second storage area to a second storage device before the delay time passes. The second storage device has a higher access speed than the first storage device.
