The Brocade® SilkWorm® 3900 Fibre Channel switch is a 32 port auto-sensing Fibre Channel core switch that combines entry-to-enterprise features and functions in a modular configuration. It combines one gigabit per second and two gigabit per second Fibre Channel throughput with advanced fabric services.
Backup and restore Brocade SilkWorm switches are at the center of storage area networks (SANs) used to enable backup and restore to be shared across several applications, reducing costs and simplifying management.
Disaster recovery Brocade SilkWorm switches play a critical role in complete disaster recovery systems, including SANs for clustering/fail-over, remote data vaulting and backup and restore functions.
Storage consolidation By consolidating storage with a SAN using Brocade SilkWorm switches, you can better manage and protect all of your business critical information.
Disk mirroring Disk SANs employing Brocade SilkWorm switches can be implemented to improve the manageability of local and remote mirroring systems, keeping online data better protected and more available.
High performance The SilkWorm 3900 switch supports a SAN fabric capable of delivering overall system availability greater than 99.999 percent. It provides up to 128 gigabits per second of aggregated throughput, with 32 ports capable of two gigabit per second full-duplex performance. For even greater performance, organizations can use Brocade ISL Trunking to achieve eight gigabit per second throughput.
Flexibility Designed for flexibility, the SilkWorm 3900 switch provides a complete solution for a departmental SAN fabric (as a small core) or for an edge switch extending the reach of an enterprise core-to-edge SAN built around the Brocade SilkWorm 12000 core fabric switch.
Investment protection The SilkWorm 3900 switch offers full backward and forward compatibility with other Brocade SilkWorm switches to provide a seamless migration path to two gigabit per second connectivity and intelligent fabric services.
Simplified management The SilkWorm 3900 switch offers Intelligent Fabric Services that centralize switch management and minimize cost of administration while simplifying allocation of storage.
Brocade Advanced Fabric Services Enables new capabilities such as hardware-enforced World Wide Name (WWN) zoning for improved security and manageability.
Brocade Fabric Shortest Path First (FSPF) FSPF enables the fabric to automatically isolate problems and reroute traffic around failed links onto alternate paths - ensuring availability for mission-critical enterprise applications.
Brocade Inter-Switch Link (ISL) Trunking Create an eight-gigabit per second data path between switches for higher performance.
Brocade Fabric Access Application Programming Interface (API) The API provides application developers with programmatic control of the fabric for discovery, zone, performance, and switch control functions.
