RFC 2143:

SCSI defines a physical and data link protocol for connecting peripherals to hosts. Devices connect autonomously to a bus and send synchronous or asynchronous messages to other devices. Devices are identified by a numeric identifier (ID). For the original SCSI protocol, devices are given a user-selectable SCSI ID between 0 and 7. Wide SCSI specifies a range of SCSI IDs between 0 and 15. A typical SCSI configuration comprises of a host adapter and one or more SCSI capable peripherals responding to asynchronous messages from the host adapter.
