Abstract:
A system and method is provided in a self-contained high speed repeater/LUN converter that allows for up to fifty-six devices to be connected to a narrow host SCSI bus via a local SCSI bus, where there does not have to be any modification of the devices on the local SCSI bus in terms of the SCSI interface. The host side of the converter supports either a single-ended or a differential SCSI bus. The converter controls all SCSI operations between the host SCSI bus and the local SCSI bus by means of a Corona device and a controller, where Corona controls all of the physical SCSI signals and the controller provides the capability to detect and respond to SCSI error conditions. The controller also selects the operation mode (LUN or repeater), board addresses, host bus type (single-ended or differential) selection, LUN/SCSI address mapping, and data mode (asynchronous, synchronous or fast synchronous) conversion.
