18 HP StorageWorks Remote Switch Version 3.1.x/4.1.x User Guide

Configuring a Remote Switch Fabric

A Remote Switch fabric requires two StorageWorks SAN Switches (2Gb, v 3x or

v4x), or StorageWorks Core Switches with identical configurations.

Remote Switch is supported over Fibre Channel for the following gateway

devices:

■ ATM

■ IP

■ SONET

■ DWDM

Most of these gateway devices include a large number of buffers to cover data

transfer over WAN.

A separate extended fabric license is not required to operate the switch at

distances much greater than 100 kilometers. This can be achieved when the switch

operates over an FCIP WAN connection.

In addition to normal switch configuration options, you can configure the

following parameters depending on the gateway requirements:

■ R_A_TOV: Resource Allocation Timeout Value

■ E_D_TOV: Error Detect Timeout Value

■ dataFieldSize: Maximum FC data field reported by the fabric

■ BB_Credit: Number of Buffer-to-Buffer credits for Nx_Port devices

■ NoClassF: Enable/Disable class F traffic

■ Suppress Class F Traffic: Disable class F traffic

Accessing the Switch using Telnet

Use telnet commands to set the following:

■ R_A_TOV and E_D_TOV values

■ Data field size
