  • Patent number: 6122723
    Abstract: Disclosed are a switching system and method for a Small Computer System Interface (SCSI). The SCSI has a plurality of ports coupled to devices having differing priorities including a highest priority (initiator) and lower priorities (targets). The present invention interconnects a plurality of the highest priority initiator devices to the lower priority target devices. A plurality of analog switches are each coupled to one of the initiator device ports and to the lower priority target device ports, preferably on a singular target bus, for selectively interconnecting the coupled initiator device to the lower priority target device ports. A controller is coupled to the initiator devices and to the plurality of analog switches, and is responsive to requests for connection from the initiator devices for arbitrating amongst the initiator devices to operate the analog switches to interconnect only one of the initiator device ports to the lower priority target device ports.
