Connecting the Jukebox With Other SCSI Peripherals
Connecting the Jukebox With Other SCSI
Peripherals
Operating this jukebox with other peripherals on the same bus is
supported, but not recommended.
In most circumstances, the recommended configuration for this jukebox
is as the only device on a SCSI bus. However, the customer may be using
the jukebox in a way that connecting other devices to the same bus will
not result in a loss of performance.
It is possible to connect this jukebox on a bus with additional peripherals
in many different ways depending on the model:
• a 2- or 4-drive jukebox using basic SCSI addressing or
• a 2- or 4-drive jukebox using logical unit numbering (LUN)
addressing
Some issues that the customer should considered when evaluating
whether other devices may be connected on the same bus as this jukebox
include the following:
• How will the jukebox be used: archiving, backup, near-line storage?
What performance must be maintained?
• How will the other device under consideration be used? How much
demand will the additional device place on the bus?
• Will "wide" and "narrow" devices have to be mixed?
• Are there devices on the internal part of the SCSI bus?
• Will a single-ended or differential interface be used?
