Brocade Silkworm 12000 fabric switch
 
The new Brocade® SilkWorm® 12000 director is a high port density, multi-protocol core fabric switch offering 64-port and dual 64-port configurations in a single enclosure. It is designed for deploying enterprise-class Storage Area Networks (SANs) in mission-critical environments.
 
Spec Summary
   
Fibre Channel ports: 128 universal ports (E,F and FL)
Up to eight 16-port Fibre Channel modules
 
Fabric latency: <2.1 msec any port to any port at 2 Gb/sec, cut through routing
 
Maximum frame size: 2112-byte payload
 
 
Applications
Disk mirroring
Disk SANs employing the Brocade SilkWorm 12000 director can be implemented to improve the manageability of local and remote mirroring systems, keeping online data better protected and more available.
Storage consolidation
By consolidating storage with a SAN using the Brocade SilkWorm 12000 director, you can better manage and protect all of your business critical information.
Disaster recovery
Brocade SilkWorm directors play a critical role in complete disaster recovery systems, including SANs for clustering/fail-over, remote data vaulting and backup and restore functions.
Backup and restore
Brocade SilkWorm directors are at the center of storage area networks (SANs) used to enable backup and restore to be shared across departments and data centers, reducing costs and simplifying management.
 
Benefits
Simplified SAN deployment
The SilkWorm 12000 director simplifies enterprise SAN deployment by combining high port density with exceptional scalability, performance, reliability and availability.
Scalability
The SilkWorm 12000 director can connect from hundreds to thousands of devices within the SAN.
Simplified management
The SilkWorm 12000 director simplifies management by networking core and edge switches under Brocade Fabric OS™, an embedded real-time operating system. This enables heterogeneous device connectivity, automatic data routing and rerouting, self-healing capabilities and scalable connectivity.
Investment protection
The SilkWorm 12000 director provides a seamless upgrade path and backward and forward compatibility with SilkWorm® entry, midrange and port aggregation offerings.
High availability
The SilkWorm 12000 director meets enterprise-class 99.999 percent availability requirements with redundant, hot-pluggable components, no single points of failure within the switch and non-disruptive software upgrades.
 
Features
Standard features:
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.
Brocade® Inter-Switch Link (ISL) Trunking
Provides a high-speed data path between switches.
Brocade Secure Fabric OS
The SilkWorm 12000 director supports Brocade Secure Fabric OS, a comprehensive SAN security architecture based on state-of-the-art networking security technology that addresses a wide variety of vulnerabilities within the SAN fabric.
Brocade Frame Filtering™
To improve security and manageability, advanced Brocade Frame Filtering™ intelligence is built directly into the SilkWorm® 12000 ASIC technology. This design enables new capabilities such as fabric zoning based on Logical Unit Number (LUN), World Wide Name (WWN) or protocol.
Brocade Fabric Shortest Path First (FSPF)
FSPF enables the fabric to automatically isolate problems and reroute traffic around failed links onto alternate paths—supporting availability for mission-critical enterprise applications.
