Host Connectivity
Library Overview
1-19
■
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. The SL3000 does not support DHCP.
FC-SCSI Connection
The SL3000 comes standard with a PUA2 Fibre Channel card, which provides an 8GB
interface and contains two ports. You can use the ports for two independent
connections to applications. Or, if the your application supports two ports for failover,
you can use the ports for failover protection.
The
SL3000 SCSI Reference Guide
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
interconnections 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.
TCP/IP Connection
The TCP/IP connection provides the host library interface (HLI) used to communicate
with library management applications, such as:
■
Open system platforms with ACSLS
■
Enterprise-level mainframes with ELS /HSC
The library controller card is responsible for coordinating all component operations
within the library and providing the interface connection with the host. There are two
separate Ethernet connections for host to library communications — Ports 2A and 2B.
■
Port 2B provides the primary host connection (standard).
■
Port 2A provides the dual TCP/IP connection (optional) or can be connected to
StorageTek Library Console (SLC).
The dual TCP/IP feature uses both ports to provide two connections between the
library and ACSLS or ELS/HSC hosts, eliminating a single point of failure. For more
information, refer to
Port Bonding
Port bonding combines multiple ports to create redundancy. The SL3000 library uses
an active-backup mode. In active-backup mode, there is one bond with two slave
Ethernet interfaces. If the active interface fails, the backup interface becomes active.
With minimum library firmware FRS_4.30 and a second Ethernet switch installed in
the library, port bonding is automatically enabled — no command or activation file is
required.
