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,
