The Brocade SilkWorm 3800 Enterprise Fibre

Channel Fabric Switch provides both 1 and

2 Gbit/sec interfaces and includes a wide range

of enhanced features to improve SAN security,

availability, performance, and manageability.

The Brocade®SilkWorm®3800

16-port, auto-sensing Fibre Channel

switch significantly increases

performance and functionality for

Storage Area Networks (SANs).

Based on third-generation Brocade

ASIC technology, the SilkWorm

3800 combines 1 Gbit/sec and

2 Gbit/sec Fibre Channel through-

put with new features that greatly

enhance switch operation.As a

result, organizations can enjoy the

advantages of higher security,

availability, and performance, as well

as centralized data management.

Designed for enterprise environments,

the SilkWorm 3800 integrates a

variety of high-availability hardware

and software features.The SilkWorm

3800 is especially useful for organi-

zations that want to upgrade their

existing environment with minimal

disruption.The switch is fully inter-

operable with existing SilkWorm

1000 and 2000 series switches—

enabling a core-to-edge architecture

that facilitates expansion, higher

performance, and higher availability.

When added to existing fabrics,

the SilkWorm 3800 automatically

assigns individual switch addresses,

establishes frame routes, and configures

the internal name server.

HIGH AVAILABILITY THROUGHOUT

THE FABRIC

The SilkWorm 3800 is designed to

provide high-availability switching at

the core of small-to-medium-sized

storage networks.The core-to-edge

SAN model features high availability

for the entire fabric through redundant

network paths. Combining the

proven reliability of the SilkWorm

family with a wide range of Advanced

Fabric Services, the SilkWorm 3800

provides a SAN fabric capable of

delivering overall system availability

greater than 99.999 percent—the

“five nines” of availability.

In addition, Brocade Fabric Shortest

Path First (FSPF) enables the fabric

to automatically isolate problems

and reroute traffic around failed

links onto alternate paths—ensuring

availability for mission-critical

enterprise applications.

Improved Security, Availability,

Performance, and Manageability

Fabric Services that increase

security through hardware-enforced

WWN zoning

• Meets high-availability requirements

with redundant, hot-pluggable

components, automatic path

rerouting, and extensive diagnostics

(ISL) Trunking to create an 8 Gbit/sec

data path between switches for

higher performance

• Protects investments through

backward and forward compatibility

with Brocade SilkWorm Fibre

Channel switches

INDUSTRY-LEADING PERFORMANCE

The SilkWorm 3800 provides high perform-

ance with all ports capable of operating at

1 and 2 Gbit/sec (full-duplex) to enable

32 Gbit/sec of uncongested switch through-

put.Auto-sensing and speed matching of

1 and 2 Gbit/sec traffic ensures interoper-

ability between current 1 Gbit/sec devices

and next-generation 2 Gbit/sec devices.

With the Brocade Extended Fabrics feature

and Dense Wave Division Multiplexing

(DWDM) technology, storage networks

can span up to 100 km over Metropolitan

Area Networks (MANs) at full bandwidth—

significantly increasing the level of disaster

protection to help ensure the highest level

of business continuance.

To provide even higher performance—

as well as simplified management—Brocade

ISL Trunking combines up to four ISLs

between a pair of switches into a single,

logical high-speed trunk running at up to

8 Gbit/sec (see Figure 1).

INTELLIGENCE WITHIN THE SWITCH

To improve security and manageability,

a wire-speed Frame Filtering engine is

built directly into the SilkWorm 3800

third-generation ASIC technology.

This design enables new capabilities such

as fabric zoning based on World Wide

Name (WWN) to be enforced through

hardware for greater security. Organizations

can improve end-to-end performance

analysis by measuring resource utilization

on a fabric-wide basis.They can track

data all the way from the source device to

the destination device to quickly identify

bottlenecks, optimize fabric configurations,

and plan for when additional capacity will

be required.

OPEN SAN MANAGEMENT

The SilkWorm 3800 simplifies management

by networking core and edge switches

with Brocade Fabric OS, an embedded

real-time operating system.This approach

enables heterogeneous device connectivity,

automatic discovery, data routing, and

scalable connectivity. In addition, the

Brocade Fabric Access API provides critical

functions for integrating applications

within the SAN environment.The API

layer is currently used by more than 50

independent software vendors to develop

feature-rich management applications that

leverage the distributed intelligence in

Brocade SANs.

INCREASES

PERFORMANCE

SEAMLESS UPGRADES,

COST-EFFECTIVE MIGRATION,

AND INVESTMENT PROTECTION

To help protect existing investments,

the SilkWorm 3800 provides a seamless

upgrade path along with backward

and forward compatibility with

SilkWorm entry, midrange, and core

fabric switch offerings.

The SilkWorm 3800 integrates with

heterogeneous environments that

include multiple operating systems

such as Windows 2000 and NT,

UNIX, Linux, HPUX, Solaris, AIX,

and others. As a result, organizations

have the flexibility to build cost-effi-

cient, and easy-to-manage enterprise

SAN fabrics.These capabilities make the

SilkWorm 3800 ideal for applications

such as LAN-free backup, server and

storage consolidation, remote mirror-

ing, and data replication.

A NEW LEVEL OF SAN SECURITY

Brocade Advanced Zoning logically

groups a SAN fabric into an unlimited

number of secure private SANs

(zones) to ensure that devices can

access only their authorized storage

resources. Zoning is enabled by the

wire-speed Frame Filtering feature of

the third-generation Brocade ASIC,

which filters and analyzes frames based

on the content of fields in the first

64 bytes of the header. Organizations

can specify hardware-enforced zones

by WWNs on the SilkWorm 3800,

simplifying administration while

providing the highest level of security

to control data access.

SUPERIOR RELIABILITY, AVAILABILITY,

AND SERVICEABILITY

Advanced SilkWorm 3800 reliability

features include the following:

• Highly reliable components

and continuous monitoring of

environmental conditions help

reduce service costs.

• Power-On Self-Test (POST)

and online diagnostics enable

administrators to monitor and test

ports while the switch is operating.

• Per-port statistics help administrators

diagnose and isolate problem ports

without disrupting switch operations.

INTELLIGENT SAN MONITORING

To simplify SAN monitoring and

maintenance, the SilkWorm 3800

provides the following functions:

• Fabric OS enables value-added

Brocade SAN monitoring and

management applications.

• Industry-standard Management

Information Base (MIB) support

enables Simple Network

Management Protocol (SNMP)-

based interfaces to access switch

information.

• Administrators can manage switch

configurations by using a command

line interface, a Web-based Java

application, or a centralized,

multifabric management application.

• Self-learning features enable the

fabric to automatically discover

and register host server and

storage devices.
