ABSTRACT:
A disk drive controller having a plurality of disk drive interfaces, each interface includes a connector, a delay circuit, and a set of power application circuits is provided to a server to support hot docking of SCA drives. Each connector is adapted to mate with a hot docking disk drive having equal length connecting pins, and detect the presence of such disk drive when the hot docking disk drive makes contact with the connector. Each delay circuit generates a set of properly delayed enabling signals to the corresponding power application circuits. Each set of power application circuits regulates power applications to the hot docking disk drive making contact with the corresponding connector. The delayed and regulated manner of applying power prevents voltage and power swings that might disrupt on-going operations and/or cause damages to the neighboring drives.
