Abstract:
A storage control apparatus for transmitting data to and receiving data from a plurality of storage devices connected to the same interface, the storage control apparatus includes a memory configured to store a management table registering a burst transfer length of each of the plurality of storage devices, the plurality of storage devices including a first storage device having a first burst transfer length that is a minimum in the management table and a second device having a second burst transfer length; an adjusting controller configured to adjust the second burst transfer length in input and/or output processing if the second burst transfer length registered in the management table is different from the first burst transfer length; and a data transfer controller configured to issue a command for a data transfer to the second storage device on the basis of the adjusted second burst transfer length.
