Quantum SuperLoader 3 Software Interface Guide 1
Chapter 1
1Theory of Operation
The SuperLoader 3 product is an integration of two separate devices, a
tape drive and a media changer. The media changer consists of all the
mechanics and electronics required to store and move tape cartridges
while the tape drive provides the read/write functionality.
Each device has a separate interface for communication to the host. The
SCSI command set supported by the tape drive is documented
separately. The SCSI command set supported by the media changer
device is detailed in “
Media Changer Command Descriptions” on page 9.
The SuperLoader 3 is fully compliant with the mandatory commands for
the ANSI SCSI-3 standard for tape drive and media changer devices and
implements many optional features.
The SuperLoader 3 does not act as an initiator on the SCSI bus. Therefore,
it does not generate unsolicited interrupts to the bus, initiate its own SCSI
commands, or assert bus reset.
