Connecting the Jukebox With Other SCSI
Peripherals
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 peripherals in many
different ways (depending on your model):
a 4- or 6-drive jukebox using basic SCSI addressing or Logical Unit Numbering
(LUN) addressing
a 10-drive jukebox with
one
host adapter and with
LUN
addressing,
daisy-chaining Bus 1 and Bus 2
together or a 10-drive jukebox using
two
host
adapters,
LUN
addressing, and using
both BUS 1 and Bus 2
interfaces
a 10-drive jukebox with two host adapters and using LUN addressing
There are many issues that must be considered when connecting other devices on a
bus with this jukebox, including the following:
how the jukebox is used; archiving, backup, near-line storage. What
performance must be maintained
how the additional peripheral will be used. How much demand will it place on
the bus
whether you will be mixing
wide
and
narrow
devices on the bus.
whether you are using both internal and external segments on your SCSI host
adapter
whether your bus is single-ended or differential
NOTE
Appendix B provides a brief overview of SCSI and the issues you must consider
when placing other peripherals on the same bus with this jukebox.
