A storage apparatus S comprises a disk controller for controlling data I/O processing between a host H and a disk unit. The disk controller includes a plurality of circuit board modules each having a circuit board and a module case storing the same, and a chassis shaped like a hollow cylinder having a front side opening and a rear side opening and configured to store the circuit board modules from the front and rear side openings. A CM module is configured to introduce cooling air from a cooling fan through an opening provided on at least one side surface toward a circuit component mounted on the circuit board. A MP module is configured to introduce cooling air by a cooling fan through an opening provide on a front surface of the module case.
