Improved 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 through­put 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 organi­zations that want to upgrade their
existing environment with minimal
disruption.The switch is fully inter­operable 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.

PERFORMANCE

INDUSTRY-LEADING PERFORMANCE

The SilkWorm 3800 provides high perform­ance with all ports capable of operating at
1 and 2 Gbit/sec (full-duplex) to enable
32 Gbit/sec of uncongested switch through­put.Auto-sensing and speed matching of
1 and 2 Gbit/sec traffic ensures interoper­ability 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.

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-effi­cient, 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 mirror­ing, 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.
