An object of the present invention is to efficiently perform a data transfer by using a plurality of data transfer devices. A storage apparatus 10 includes: a channel control unit 11 having a first DMA 1142, a second DMA 1112, and a memory 113; a processor unit 12; and a drive control unit 13 that communicates with a storage device 17. When the channel control unit 11 transfers to a host computer 3 data stored in a cache memory 14, the first DMA 1142 receives from a processor unit 12 a setting of a first transfer parameter 151 for the first DMA 1142 containing a second transfer parameter 152 for the second DMA 1112, performs a first data transfer from the cache memory 14 to the memory 113 according to the first transfer parameter 151, and sets the second transfer parameter in the second DMA 1112 thereby to cause the second DMA 1112 to perform a data transfer from the memory 113 to the host computer 3.
