Preface

Introduction

This document discusses the practical aspects of designing, deploying, and maintaining a SilkWorm

12000 based SAN. The SilkWorm 12000 is a new product because it has: a bladed architecture, two

logical switches in one chassis, a new Fabric OS (version 4.0), and high availability/failover features.

Several SilkWorm 12000 features, while introduced in the SilkWorm 3800, require further discussion

within the context of the SilkWorm 12000, such as Trunking and 1-2 Gbit/sec auto-sensing ports. Other

considerations include designing and deploying SilkWorm 12000 based SANs and the integration of the

SilkWorm 12000 into existing SANs built with SilkWorm 2x00 and 3x00 technology.

This document addresses these new features and capabilities in a clear and concise manner, with liberal

use of examples, and is intended to be used in conjunction with SilkWorm 12000 manuals (see

References later in this section).

While working with the SilkWorm 12000, a multitude of decisions are necessary. This guide is intended

to identify the key decision points expected during the lifecycle of a SilkWorm 12000 deployment and

the advantages and disadvantages of adopting a particular approach. Also included in this guide are tips,

shortcuts, and suggestions for the efficient operation and maintenance of the SilkWorm 12000, which

are gathered from the engineers who developed and tested the SilkWorm 12000.

Audience for This Document

This guide is intended for technically focused personnel directly or indirectly responsible for the design,

deployment, and management of SilkWorm 12000 based SANs. The reader is expected to be familiar

with and have a working knowledge of SAN technology, Brocade SilkWorm switches, and Brocade

Fabric OS.
