Abstract: A control device includes a processor. The processor is configured to receive an execution request for write processing of writing data of logical volumes to second physical volumes. The data of the logical volumes is stored in first physical volumes. The processor is configured to generate write information on basis of data sizes of the respective logical volumes and free spaces of storage areas of the respective second physical volumes. The processor is configured to perform, on basis of the write information, control of writing first data of the logical volumes from a cache unit to the second physical volumes. The processor is configured to perform control of reading second data of the logical volumes from the first physical volumes to the cache unit. The processor is configured to optimize the write information in response to completion of the control of reading.
