Supported Internet Protocols
The library supports the following Internet protocols:

v IPv4

v IPv6

SNMP Messaging
Occasionally, the library may encounter a situation that you want to know about,
such as an open magazine or a fault that causes the library to stop. The library
provides a standard TCP/IP protocol called Simple Network Management Protocol
(SNMP) to send alerts about conditions (such as need for operator intervention)
over a TCP/IP LAN network to an SNMP monitoring station. These alerts are
called SNMP traps. Using the information supplied in each SNMP trap, the
monitoring station (together with customer-supplied software) can alert operations
personnel of possible problems or operator interventions that occur.
In summary, each trap provides the following information:

v Product Identification such as product name, description, manufacturer, model

number, firmware level, and the URL that the trap is designated for.

v Product Status such as the severity of the trap, status (current and previous) and

the time the trap occurred.

v Library State (physical device status) such as identification and status of devices

that are monitored. In the case of the library, it would include enclosure, power
supply, controller, magazine status, drive count, cartridge slot count, and I/O
station count. Also included would be certain library statistics, and where
appropriate, the fault FSC (fault symptom code) including the severity and
description of that fault.

v Drive Status such as the identification of each drive in the library, firmware

level, serial number and other address and status information.

v Trap Definitions such as library status change, open magazine, I/O accessed,

hard fault information, drive cleaning requests, excessive retries and library

returning to normal operations.

Maximum Library Storage Capacity and Data Transfer Rate
Maximum library storage capacity and maximum data transfer rates are as follows:
Table 1-4. Tape drive model and interface type
Tape Drive Model Host Interface
Ultrium 4 Full height drives v 4 Gb/s Fibre Channel
v 3 Gb/s Serial Attached SCSI (SAS) - dual port
Ultrium 4 Half height drives v 3 Gb/s SAS - single port
Ultrium 3 Full height drives v Ultra160 SCSI LVD (depending on drive; single-ended (SE) is not
recommended as it will severely degrade performance)
v 4 Gb/s Fibre Channel
Ultrium 3 Half height drives v 3 Gb/s SAS - single port
