ABSTRACT:
A method for transferring data in a controller having a processor and a controller support device, with the controller connected to a host device and a disk drive. The method includes the steps of providing the controller with a first bus and a second bus, connecting a first bus between the disk drive and the host device, connecting a second bus between the processor and the controller support device, transferring first data between the disk drive and the host device across the first bus, and transferring second data between the processor and the controller support device across the second bus without consuming any portion of the bandwidth of the first bus. A controller architecture is also disclosed.
