SCSI Cable Connections
NOTE
Refer to “Fibre Channel Cable Connections” on page 1-16 if the library is
configured with Fibre Channel.
This section illustrates a standard SCSI configuration that produces a
high level of data storage performance (one SCSI host bus adapter for
each drive in the library, with the library controller daisy-chained to the
first drive). HP supports up to two drives per SCSI host bus adapter, but
recommends only one drive per bus. If compression is used when
attaching two drives per bus, keep in mind the combined transfer rate of
the drives must not exceed the throughput of the host bus adapter used
or performance will be degraded.
Connect the library as follows (refer to Table 1-4 on page 1-15):
1. Properly power off all peripheral devices connected to the host
computer.
2. Power off the host. If the host is connected to a network, check with
the system administrator before turning off power.
3. Connect a 68-pin jumper cable from the top connector of the library
controller to the left drive module on level 1 (drive module 1).
CAUTION
Use SCSI cables and HVDS differential terminators for high-voltage
SCSI interfaces. User SCSI cables and LVDS differential terminators for
low-voltage SCSI interfaces. The label on the library controller indicates
high- or low-voltage.
4. Connect the appropriate 68-pin SCSI terminator to the bottom
connector on the library’s controller card.
5. Connect a 68-pin SCSI cable from a host SCSI card to each drive
module. Add the appropriate terminators to the remaining SCSI
connectors.
6. Connect the remote management card (see “Using the Remote
