All SCSI devices in a Solbourne system use a three layer device driver scheme. The top layer supports a specific type of device (for example disk sd(4s), or tape st(4s)), the middle layer contains common code (scsi(4)), and the lower layer supports specific host adaptor hardware (for example SCSI IOASIC si(4), or SCSI Rimfire sr(4s)).  This man page describes the low layer operations for the SCSI IOASIC host adaptor. 

The controller line above describes the SCSI IOASIC host adapter on the Solbourne system board.
