Host Connectivity
The SL3000 library supports two types of host connections:
Small computer system interface over a physical Fibre Channel interface (FC-SCSI)
■
Ethernet using 10/100 Base-T and CAT-5 cable (TCP/IP)
■
In a non-partitioned configuration, the library can use only one interface type, either
FC-SCSI or TCP/IP. In a partitioned configuration, the library can have one interface
type per partition.

FC-SCSI Connection

A PUA2 Fibre Channel (FC) card must be purchased to provide a FC-SCSI connection
to the library. The card provides a single or optional dual port feature, with an 8 Gb
connection.
The SL3000 Interface Reference Manual contains information about the SCSI command
set, FC operations, command implementations, topologies, cables, and connectors.

Supported Topologies

Switched Fabric — Oracle recommends this topology. It provides dynamic
■
inter-connections between nodes and multiple, simultaneous FC connections. If
the library is connected to a FC switch or fabric-capable host, it configures itself as
a switched topology and can support up to 16 million ports logged into the fabric.
Arbitrated Loop — While the library supports the arbitrated loop topology, Oracle
■
does not recommend it. This topology provides multiple connections for devices
that share a single loop and allows only point-to-point connections between an
initiator and target during communications. An arbitrated loop can connect only
up to 126 ports.
