ABSTRACT:
A storage device controller has a channel controller; a disk controller; and a first memory for storing data delivered between the channel controller and the disk controller. The channel controller has a circuit board on which a first processor, a file access processor having a second processor and a second memory, a data transfer device and a third memory are formed. The second processor transmits information indicating the storage position of data in the second memory to the first processor, the first processor writes into the third memory data transfer information containing information indicating the storage position of data in the first memory and information indicating the storage position of the data in second memory, and the data transfer device reads out data transfer information from the third memory and controls the data transfer between the first memory and the second memory on the basis of data transfer information thus read out.
