ABSTRACT:
A SCSI adapter card which provides one or more internal SCSI channels and includes connectors for an optional daughter card which provides an external SCSI connector. The daughter card is a parallel mezzanine style daughter board which provides modular and upgradable SCSI bus routing options. In the preferred embodiment, the adapter card includes two SCSI controllers which provide two internal SCSI channels. The daughter board can include up to 2 SCSI controllers for additional SCSI channels. The daughter board can reroute one or more of the internal SCSI channels to the external connector according to various SCSI routing options or can include one or more SCSI controllers for additional SCSI channels. In one embodiment, the daughter board does not include a SCSI controller, but rather serves to reroute one or more of the internal SCSI controllers to the external connector. In a second embodiment, the daughter board includes one or more SCSI controllers which provide external SCSI channels in addition to the internal SCSI channels. The incorporation of the external SCSI connector on the daughter board eliminates the need for the base PWA add-in card to include the external SCSI connector and also eliminates the requirement for internal "umbilical" cables which burden mechanical limitations, decrease the reliability and complicate manufacturing and service.
