System Requirements and Compatibility

Compatibility with other Products

Fabric OS version 3.0.1b or later can be installed and run on the FC Entry Switch 8B, FC Switch

8B, and FC 16B products.

The FC Entry Switch 8B, FC Switch 8B, and the FC 16B switch running Fabric OS version 3.0.1b

or later can operate in the same fabric with the HP Brocade 2400/2800 and FC 6164 switches

running the a2.4.1 or later versions of Fabric OS.

For more information about configuring FC Entry Switch 8B, FC Switch 8B, FC 16B, HP Brocade

2400/2800, and FC 6164 products to operate in the same fabric, contact your switch supplier.

Introducing QuickLoop

This chapter provides the following information:

•Overview on page 1-1

•QuickLoop Basics on page 1-1

•Address Translation on page 1-2

•Combining QuickLoop and Zoning on page 1-2

Overview

QuickLoop allows arbitrated loops to be attached to a fabric. Without modifying their drivers,

private target on the arbitrated loops can be accessed by public or private hosts elsewhere on the

fabric.

Devices attached to QuickLoop communicate with all other devices attached to the same

QuickLoop. However, private devices attached to QuickLoop communicate only with devices

within the same QuickLoop. Public devices in an arbitrated loop mode are considered private

devices when connected to QuickLoop ports.

Zoning enables the set of storage devices visible to specific hosts can be carefully administered.

The QuickLoop and Zoning combination allows a private host to fully participate in a Storage Area

Network (SAN).

QuickLoop Basics

QuickLoop is a unique Fibre Channel topology that combines arbitrated loop and fabric topologies.

An arbitrated loop supports communication between devices that are not fabric-aware. Such

devices are called private devices, and arbitrated loops are sometimes called private loops.

QuickLoop allows an FC Entry Switch 8B, FC Switch 8B, or FC 16B switch to emulate a hub

environment, while offering the additional benefit of connectivity to a fabric.

A QuickLoop consists of multiple private arbitrated looplets (a set of devices connected to a single

port) that are connected by a fabric. All devices in a QuickLoop share a single AL_PA bit-map and

behave as if they are in one loop. This allows private devices to communicate with other devices

over the fabric, provided they are in the same QuickLoop.

A particular QuickLoop can be configured to consist of selected devices or looplets connected to

the ports of one switch, or to a cascaded switch pair.

1-2 QuickLoop User’s Guide

Introducing QuickLoop

QuickLoop provides a possible migration path starting with deploying a single private loop and

later deploying a fabric-based SAN. In this scenario, QuickLoop-enabled switches can be used to

replace hubs when the SAN is first deployed and has only private devices attached. Then, as the

SAN grows, fabric switches can be added without any detrimental effect to the QuickLoop-enabled

switches.

Address Translation

Address translation is transparent and requires no actions on the part of the user. It is achieved

through hardware translative mode (also known as phantom mode), in which a device not

physically located in a looplet is made addressable by a unique AL_PA in that looplet.

There are two hardware translative modes available to a QuickLoop-enabled switch:

•Standard translative mode

Allows public hosts to communicate with private target devices across the fabric. Standard

translative mode is available as an integral part of Fabric OS, and does not require QuickLoop.

•QuickLoop mode

Allows private hosts to communicate with private target devices across the fabric when

configured in the same QuickLoop. Also allows private host to communicate with public target

in the same QuickLoop.

In mixed mode individual ports within a switch are set by configuration commands to one of the

above two modes.

The switch automatically determines and sets the appropriate mode, based on factory defaults and

configurations currently in effect.

Combining QuickLoop and Zoning

QuickLoop can be used in conjunction with Zoning.

In addition to zoning fabrics, QuickLoop Zoning also allows you to zone QuickLoops, enhancing

management of a Fibre Channel Arbitrated Loop (FC-AL) in a legacy environment.

In QuickLoop Zoning, devices within a QuickLoop can be partitioned off within that QuickLoop to

form QuickLoop zones; in other words, a QuickLoop zone is a subset of QuickLoop and can

include only devices in QuickLoop.

Fabric zones and QuickLoop zones are independent of each other; both types of zones can co-exist

in the same zone configuration. Hosts in a QuickLoop can see only targets contained within a

QuickLoop.

Zoning adds the following features:

•Devices from multiple QuickLoops can be added to the definition for a fabric zone.

Even an identical AL_PA from two different QuickLoops could be configured under a fabric

zone. Zoning can correctly direct traffic to the different devices.

•Additional control over access to QuickLoop devices.

Fabric devices in a zoned fabric can only access the QuickLoop (and fabric) devices that are in

the same zone.
