NOTE NOTE Setting Up the Jukebox Connecting the Jukebox with Other SCSI Devices Connecting the Jukebox with Other SCSI Devices 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, your use of the jukebox may be such that other devices could be connected to the bus without a loss of performance. It is possible to connect this jukebox on a bus with additional devices in different ways (depending on your 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 must be considered when connecting other devices on a bus with 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 it place on the bus? • Will you be have to mix "wide" and "narrow" devices on the bus? • Are there devices on the internal part of the SCSI bus? • Will you be using a single-ended interface or a differential interface? Appendix B provides a brief overview of SCSI and the issues you must consider when placing other devices on the same bus with this jukebox. 1-12 Chapter 1

Setting Up the Jukebox
Connecting the Jukebox with Other SCSI Devices
Connecting the Jukebox with Other SCSI
Devices
NOTE
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, your use of the jukebox may be such that other
devices could be connected to the bus without a loss of performance.
It is possible to connect this jukebox on a bus with additional devices in different
ways (depending on your 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 must be considered when connecting other devices on a bus with
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
it place on the bus?
•
Will you be have to mix
“
wide
”
and
“
narrow
”
devices on the bus?
•
Are there devices on the internal part of the SCSI bus?
•
Will you be using a single-ended interface or a differential interface?
NOTE
Appendix B provides a brief overview of SCSI and the issues you must consider
when placing other devices on the same bus with this jukebox.
