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
