6.5 Installing and Configuring Fibre Channel Hardware
This section provides information about installing the Fibre Channel
hardware needed for a TruCluster Server configuration accessing storage
over the Fibre Channel.
Ensure that the member systems, the Fibre Channel switches, and the
HSG80 array controllers are placed within the lengths of the optical cables
you will be using.
______________________ Note _______________________
The maximum length of the optical cable between the KGPSA and
the switch or switch and the HSG80 array controller is 500 meters
via shortwave multimode Fibre Channel cable. The maximum
distance between switches in a cascaded switch configuration is
10 kilometers using longwave single-mode fibre.
6.5.1 Installing and Setting Up the Fibre Channel Switch
The Fibre Channel switches support up to 8 (DS-DSGGA-AA/DS-DSGGB-AA)
or 16 (DS-DSGGA-AB/DS-DSGGB-AB) full duplex 1.6025 Gbits/sec
ports. Each switch port can be connected to a KGPSA-BC or KGPSA-CA
PCI-to-Fibre Channel host bus adapter, an HSG80 array controller, or
another switch.
Each switch, except the DS-DSGGB-AB, has a front panel display and four
push buttons that you use to manage the switch. There are four menus
that allow you to configure, operate, obtain status, or test the switch. The
DS-DSGGB-AB is managed by way of a telnet session once the IP address
has been set (from a PC or terminal).
All switches have a 10Base-T Ethernet (RJ45) port, and once the IP address
is set, the Ethernet connection allows you to manage the switch:
• Remotely using a telnet TCP/IP connection
• With Simple Network Management Protocol (SNMP)
• Using Web management tools
______________________ Note _______________________
You have to set the IP address and subnet mask from the front
panel (or from a PC or terminal with the DS-DSGGB-AA) before
