ABSTRACT:
A drive controller for controlling multiple disk drives is disclosed. In one embodiment, the drive controller includes a physical interface circuit configured for coupling to a peripheral bus. A plurality of serial interface engines may be coupled to the physical interface circuit. A buffer may be coupled to each of the plurality of serial interface engines and an interface controller. The interface controller may be configured for coupling to a plurality of disk drives. Since the drive controller includes only a single physical interface circuit, a single buffer, and a single interface controller, its complexity is reduced to near that of a single drive controller while being capable for simultaneously providing interfaces for each of a plurality of disk drives.
