Environmental Conditions; Physical Distance Between; The Library And A Host Workstation - HP StorageWorks ESL9000 Series Manual

Selecting an Installation Location

Environmental Conditions

The installation site must provide the following environmental conditions during
normal library operation:
• Humidity: 20% to 80% non-condensing
• Temperature: 59°F to 90°F (10° to 32°C)
• Altitude: sea level to 10,000 feet (3,048 m)
NOTE: For additional library specifications refer to Appendix A of the hp StorageWorks
ESL9000 Series Tape Library Reference Guide .

Physical Distance Between

the Library and a Host Workstation

The maximum physical distance between the library (SCSI bulkhead) and the SCSI
connector on a host workstation is dictated by the Low Voltage Differential (LVD) bus
characteristics (see Table 2-1 and Table 2-2).
NOTE: For the ESL9198, ESL9322, and most ESL9326/ESL9595 libraries, a SCSI bus
extender is used for bus 1 (robotic controller, drive 0, drive 1.) For the other drive pairs (D2, D3),
(D4, D5), (D6, D7), (D8, D9) no internal SCSI extender is used. See Table 2-1 and Table 2-2 for
the maximum external SCSI bus cable lengths.
SCSI bus extenders can be purchased for other drive pairs.
