Increased Efficiency to Manage
Business Growth
As the value and volume of business
data continue to rise, organizations
are constantly challenged to “do more
with less.”These organizations need
technology solutions that are easy to
implement and manage, that can grow
and change with minimal disruption,
and that offer dramatic operational
efficiencies.Today, Brocade® Storage
Area Network (SAN) solutions can
help organizations simplify their
IT management infrastructures,
shrink data backup windows,
improve system performance,
and reduce overall storage costs.
The Brocade SilkWorm® 3250
8-port Fibre Channel switch
significantly increases performance
and functionality for SANs at an
entry-level price. Based on thirdgeneration Brocade technology,
the SilkWorm 3250 provides
auto-sensing 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 low-cost device connectivity
and powerful capabilities that make
SAN technology highly accessible
and affordable.
PAY-AS-YOU GROW SCALABILITY
Designed for small and mediumsized organizations, the SilkWorm
3250 integrates innovative hardware
and software features that make it easy
to deploy, manage, and integrate into
a wide range of IT environments.
With these powerful yet flexible
capabilities, the SilkWorm 3250
enables organizations to start small
and grow their storage networks in a
scalable, non-disruptive, and efficient
manner.This is especially beneficial
for organizations that need to upgrade
their existing SAN environment
with minimal disruption.

EFFICIENCY
HIGH AVAILABILITY THROUGHOUT THE FABRIC
The SilkWorm 3250 is designed to provide
high-availability switching at the edge 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
optional Advanced Fabric Services, these
switches provide a SAN fabric capable of
delivering overall system availability greater
than 99.999 percent. In addition, Brocade
Fabric Shortest Path First (FSPF) enables
the fabric to automatically isolate problems
and reroute traffic around failed links onto
alternate paths—increasing availability for
mission-critical enterprise applications.
BACKWARD AND FORWARD COMPATIBILITY
The SilkWorm 3250 is fully interoperable
with existing SilkWorm 1000 and 2000
series switches—supporting entry fabrics
that serve a variety of purposes, such
as easing e-mail storage growth and
streamlining data backup. In addition,
the SilkWorm 3250 is compatible with
newer Brocade SAN switches and
directors, providing the ability to seamlessly
expand to more sophisticated core-to-edge
network architectures as business needs
dictate. As a result, these capabilities
make it ideal for key SAN solutions
such as LAN-free backup and server
and storage consolidation.
A BETTER WAY TO IMPROVE
BUSINESS OPERATIONS
One of the primary benefits of a SAN
environment is the consolidation of
hardware resources in an easy-to-manage
infrastructure.This centralized approach
helps increase operational efficiency and
staff productivity, two critical requirements
for small and medium-sized businesses.
With fewer physical resources to manage,
staff members can handle additional
business growth or focus on other
strategic initiatives.
The high-performance 2 Gbit/sec Fibre
Channel capabilities of the SilkWorm 3250
speed data transfer to help keep data flowing and applications running. As a result,
organizations can significantly improve
storage utilization in distributed e-mail
environments, for example. Consolidating
e-mail applications on a SAN can increase
data availability by greatly reducing backup
and restore windows—in some cases by as
much as 90 percent.

In addition, a SAN-based architecture
enables LAN-free backup and more
efficient storage resource management—
increasing overall system performance
and productivity (see Figure 1).
SUPERIOR NETWORK PERFORMANCE
The SilkWorm 3250 provides high
performance with all ports capable
of operating at 1 and 2 Gbit/sec
(full-duplex) to enable up to
32 Gbit/sec of uncongested throughput. Auto-sensing and speed matching
of data traffic ensures interoperability
between 1 Gbit/sec and 2 Gbit/sec
devices.To provide even higher
performance, optional Brocade
Inter-Switch Link (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.
SIMPLIFIED MANAGEMENT
All SilkWorm switches are based on
the intelligent Brocade Fabric OS,
which provides the integrated building
blocks for highly reliable and scalable
SAN environments.To manage their
switch configurations, organizations
can use a command line interface,
the Brocade WEB TOOLS Java
application, or the Brocade Fabric
Manager multifabric management
application. In addition, Brocade
offers the following advanced
software solutions to further
enhance business operations:
• Brocade Advanced Zoning permits
only authorized devices and
applications to access data, thereby
increasing security and control.
• Brocade Advanced Performance
Monitoring enables end-to-end
performance monitoring of the
entire SAN fabric.
• Brocade Fabric Watch enables
organizations to proactively monitor
the health of the network with
comprehensive thresholds and alerts
that help prevent outages.
• Brocade Secure Fabric OS® helps
ensure that all of these management
capabilities are available in a secure
environment.
• The Brocade Fabric Access API
enables the integration of a broad
range of powerful Brocade SilkWorm
switch functions into popular thirdparty management tools, enabling
organizations to continue using their
storage management tools of choice.
SEAMLESS UPGRADES TO
