Brocade Silkworm 3900 fabric switch |
| 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. |

|
Applications |
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.
|
Storage
consolidation
By consolidating storage with a SAN using Brocade
SilkWorm switches, you can better manage and protect
all of your business critical information.
|
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. |
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. |
|
| |
|
Benefits |
Simplified management
The SilkWorm 3900 switch offers Intelligent Fabric
Services that centralize switch management and
minimize cost of administration while simplifying
allocation of storage. |
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. |
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. |
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. |
|
| |
|
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
Create an eight-gigabit per second data path between
switches for higher performance. |
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
Advanced Fabric Services
Enables new capabilities such as hardware-enforced
World Wide Name (WWN) zoning for improved security
and manageability. |
