Fibre Channel interface
This section describes Fibre Channel technology and where to find additional
information for drives that use a Fibre Channel interface.
Attention:
This product contains an assembly that complies with the
performance standards set by the U.S. Food and Drug Administration
for a Class I Laser Product. This laser assembly is registered with the
Department of Health and Human Services and is in compliance with
IEC825.
In the TS3500 Tape Library, for drives that use a Fibre Channel interface the
following information is available:

Fibre Channel technology combines the best features of traditional input/output
interfaces (such as the throughput and reliability of SCSI and Programmed Control
Interrupt) with the best features of networking interfaces (such as the connectivity
and scalability of Ethernet and Token Ring). The technology offers a transport
mechanism for delivering commands, and provides high performance by allowing
processing to be done in the hardware.
You can establish Fibre Channel connections between Fibre Channel ports that
reside in the TS3500 Tape Library, one or more servers, and the network
interconnecting them. The network can consist of such elements as switches, hubs,
bridges, and repeaters used in the interconnection.
Small Computer System Interface
This section sets forth the conditions that apply to drives in the TS3500 Tape
Library that use a Small Computer System Interface (SCSI) interface.
The TS3500 Tape Library operates as a set of SCSI-3 devices. For drives that use a
SCSI interface, the following conditions apply:
v
The Ultrium 2 tape drive attaches to a server through a Low Voltage Differential
(LVD) Ultra160 SCSI interface or a High Voltage Differential (HVD) Ultra SCSI
interface
v
The Ultrium 1 tape drive attaches to a server through an LVD Ultra2 SCSI
interface or an HVD Ultra SCSI interface
Each SCSI drive canister uses shielded, VHDCI, 68-pin connectors and can attach
directly to a 2-byte-wide SCSI cable.
Note:
The earlier version of the SCSI drive used HD68 connectors and was
packaged on a tray (sled). While drive trays are still supported, they can no longer
be ordered. For information about the replacement design, contact your IBM
representative.
