The Brocade®SilkWorm®3900

32-port, auto-sensing Fibre Channel

switch provides an intelligent and

cost-effective solution to meet a

wide range of Storage Area

Network (SAN) requirements.

As the latest addition to the Brocade

2 Gbit/sec fabric switch family,

the SilkWorm 3900 is ideal for

organizations that face rapidly

changing storage requirements.

With the performance capabilities

of an enterprise switch and the

cost-effectiveness of a modular

switch solution, the SilkWorm 3900

enables a flexible SAN infrastructure.

Designed for midsize to large storage

networks, the SilkWorm 3900

enables organizations to implement a

SAN infrastructure that best meets

their current needs and expands

seamlessly as their storage requirements

evolve.The SilkWorm 3900 provides a

complete solution for a departmental

SAN fabric, as a small core, or an

edge switch extending the reach of

an enterprise core-to-edge SAN

built around Brocade SilkWorm

Directors (see Figure 1).

Based on a third-generation

Brocade intelligent architecture,

the SilkWorm 3900 provides a

highly available, scalable, and secure

foundation for SAN applications

such as high-speed data backup,

server and storage consolidation,

remote mirroring, and long-distance

data replication.

Increased Flexibility for Evolving

SAN Requirements

Highlights

along with auto-sensing 1 and

2 Gbit/sec interfaces for seamless

integration with existing fabrics

• Leverages Brocade Advanced Fabric

Services to provide the highest

levels of SAN performance, security,

and manageability

• Meets mission-critical availability

requirements with network resiliency,

automatic data path rerouting, hot

code activation, and redundant,

hot-pluggable components

• Increases performance by employing

Brocade Inter-Switch Link (ISL) Trunking

to create a data path with up to

8 Gbit/sec throughput per trunk

• Provides substantial cost savings by

supporting a SAN infrastructure that

increases productivity, maximizes IT

resource utilization, and reduces

capital expenditures

• Supports FICON®and FICON in-band

management (CUP)

attractive price.

SILKWORM SWITCH FAMILY

HIGH AVAILABILITY FOR

BUSINESS CONTINUANCE

By combining the proven reliability of

the SilkWorm switch family with a wide

range of hardware and software availability

features—such as non-disruptive upgrades

of switch software—the SilkWorm 3900

supports a SAN fabric capable of delivering

overall system availability greater than

99.999 percent.

The core-to-edge SAN model uses

redundant fabrics, hot-pluggable

components, and multiple data paths to

help ensure high availability across the

fabric. In addition, Brocade Fabric Shortest

Path First (FSPF) enables the fabric to

automatically isolate problems and reroute

traffic around failed links onto alternate

paths. As a result, the SilkWorm 3900

provides a SAN infrastructure solution that

is designed to meet the most demanding

business continuance requirements.

INDUSTRY-LEADING PERFORMANCE

The SilkWorm 3900 provides numerous

business advantages for organizations that

want to increase application performance

and operational productivity. It can deliver

up to 128 Gbit/sec of aggregated through-

put, with 32 ports capable of 2 Gbit/sec

full-duplex performance.To achieve even

higher performance, organizations can use

Brocade ISL Trunking, which combines as

many as four ISLs into a single logical ISL

with up to 8 Gbit/sec throughput.

Fibre Channel speed is also possible at

longer distances for remote operations.

By leveraging 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

high speed—significantly enhancing

disaster recovery operations.

A DESIGN TO LEVERAGE INTELLIGENCE IN

THE FABRIC

To help maximize IT investments and

reduce costs, the SilkWorm 3900 is

designed to leverage the industry’s only

intelligent fabric services architecture.

The proven intelligence in the Brocade

Fabric OS®and third-generation Brocade

ASIC technology enables the high levels

of security, management, and performance

required by the most demanding

SAN environments.

Organizations can utilize leading capabilities

such as frame filtering and Brocade

Advanced Fabric Services to unlock the

intelligence of the Brocade SAN fabric

for a variety of applications. For instance,

Brocade Advanced Zoning enables

organizations to implement robust,

Advanced Performance Monitoring

provides fabric-wide performance

analysis to support tasks such as load

balancing and application charge-back.

And ISL Trunking provides

8 Gbit/sec throughput to support

high-performance applications.

OPEN SAN MANAGEMENT

The SilkWorm 3900 simplifies SAN

management by networking core

and edge switches under a common

management platform based on

Brocade Fabric OS. An embedded

real-time operating system, Fabric OS

includes standard management inter-

faces, a full range of management

tools, and a Brocade Fabric Access API

that supports third-party SAN manage-

ment applications.This open systems

approach enables heterogeneous device

connectivity, automatic data routing,

and a seamless upgrade path among

all SilkWorm products.

To simplify SAN administration

and reduce management costs,

the SilkWorm 3900 supports the

following functions:

• Simple Network Management

Protocol (SNMP)-based interfaces to

access switch information

• Switch management through a

command line interface,

WEB TOOLS, or Fabric Manager

• End-to-end fabric visibility through

Advanced Performance Monitoring

• Real-time health monitoring

through Fabric Watch

• Third-party SAN management

application development through

SMI-S and the Fabric Access API

SEAMLESS UPGRADES AND

INVESTMENT PROTECTION

To protect existing investments,

the SilkWorm 3900 provides backward

and forward compatibility with the

SilkWorm family of switches. In addi-

tion, translative mode capabilities

enable legacy private loop devices to

join the Fibre Channel SAN fabric.

The SilkWorm 3900 integrates with

heterogeneous environments that

include operating systems such as

Windows NT, UNIX, z/OS, and

Linux—giving organizations the flexi-

bility to select storage solutions that best

match their particular needs. As a result,

these organizations can more easily

implement cost-efficient and highly

manageable enterprise SAN fabrics.

HIGHER FABRIC SECURITY FOR

CRITICAL INFORMATION

The SilkWorm 3900 is designed to

provide the highest level of SAN fabric

security to help organizations safeguard

their critical information. For example,

Brocade Zoning logically groups a SAN

fabric into secure zones to help ensure

that SAN-attached devices can access

only their authorized storage resources.

Advanced Zoning provides even more

control over the fabric through robust

hardware-enforced zoning by WWN.

These capabilities enable organizations

to simplify administration while

significantly increasing their control

over data access.

MAXIMIZING SAN INVESTMENTS

Brocade and its partners offer

complete SAN solutions to meet a

wide range of technology and business

requirements.These solutions include

education and training, support,

service, and professional services to

help optimize SAN investments.
