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,
