  • Hard disk drive controller having versatile chip connector having printed circuit board engaged by at least two data ports having two pairs of differential connector elements
    Patent number: 7529858
    Abstract: A hard disk controller (HDC) chip has interchangeable “A” and “B” ports of differential connector element pairs, with one connector element of each pair being disposed closest to the edge of the chip and with the other element inboard of it to facilitate connection to more than one printed circuit board (PCB) serial interface pinout without crossing traces of a pair and with maintaining traces of a pair parallel and on the same PCB level.

  • Method and system for allowing a plurality of SCSI hosts to interact with a DASD storage subsystem
    Patent number: 6128683
    Abstract: The present invention provides a system for configuration and running a DASD storage subsystem where the small computer system interface (SCSI) Target behavior needs to be different depending on type and characteristics of the attaching SCSI hosts. The configuration process defines the behavior by SCSI bus port through the use of bus behavior tables. Accordingly, several ports are able to operate correctly based on the hosts that attach to separate ports. In a first aspect, a direct access storage device (DASD) storage subsystem is described. The DASD storage subsystem comprises a plurality of ports, each of the plurality of ports including a table. Each of the tables defines the behavior of the particular port as a SCSI target. The DASD storage subsystem includes a mechanism for configuring the plurality of ports utilizing the tables within the ports. In a second aspect, a SCSI system is described. The SCSI system comprises a plurality of SCSI hosts and a DASD storage subsystem.
