The Brocade SilkWorm 24000 Director provides  
a highly reliable and intelligent solution for  
enterprise-class Storage Area Networks (SANs)  
in mission-critical environments.  
SILKWORM 24000 DIRECTOR  
Highlights  
A High-Port-Density, Multiprotocol  
Director for Enterprise SANs  
• Delivers up to 128 ports in a single  
domain and a 14U enclosure with up  
to 384 ports in a single rack, facilitat-  
ing more easily managed SAN fab-  
rics with thousands of ports  
With state-of-the-art performance  
and enhanced scalability for both  
open system and IBM zSeries server  
enterprise SAN environments, the  
supporting thousands of hosts and  
storage devices (see Figure 1).Whether  
used as a core building block for an  
enterprise fabric or as a standalone  
director, the SilkWorm 24000 is a  
reliable, high-availability solution.These  
capabilities make it ideal for enterprise  
management and high-volume trans-  
action processing applications such as  
ERP and data warehousing, as well  
as data backup, remote mirroring,  
and high-availability clustering.  
• Meets ultra-high-availability require-  
ments with redundant, hot-pluggable  
components, no single points of  
failure, non-disruptive software

®
Brocade SilkWorm 24000 Director  
provides unique capabilities to meet  
demanding mission-critical require-  
ments. It scales non-disruptively  
from 32 to as many as 128 concur-  
rently active 2 Gbit/sec full-duplex  
ports in a single domain or two  
domains of up to 64 ports each. In  
addition, it offers improved perform-  
ance and the potential to upgrade to  
higher-speed connectivity in the  
future.The SilkWorm 24000 also  
leads the industry in power and  
cooling efficiency, helping to reduce  
total cost of ownership.

• Provides FICON support for IBM  
zSeries server environments, includ-  
ing intermix mode on a port-by-port  
basis, cascaded FICON fabrics,  
1 and 2 Gbit/sec FICON speeds,  
and CUP support  
• Increases performance through reduced  
latency and Brocade Inter-Switch Link  
(ISL) Trunking  
• Leverages intelligent Brocade SAN  
management and security tools to  
increase operational efficiency and  
maximize SAN investments  
The SilkWorm 24000 is designed to  
integrate with heterogeneous envi-  
ronments that include IBM zSeries  
server and open platforms with  
multiple operating systems such as  
Microsoft Windows, Linux, Solaris,  
HP-UX,AIX, and i5/OS. As a result,  
Brocade-based SANs can help serve  
as the foundation for implementing  
utility computing and Information  
Lifecycle Management (ILM).  
• Protects investments by enabling  
upgrade paths to future technologies,  
increased port speeds, IP connectivity,  
and more  
With its intelligent fourth-generation  
ASIC, the SilkWorm 24000 provides  
a reliable foundation for core-to-edge  
SANs, enabling fabrics capable of

In addition, exchange-based Dynamic  
Path Selection (DPS) optimizes fabric-  
wide performance and load balancing  
by automatically routing data to the  
most efficient available path in the  
fabric. DPS augments ISL Trunking to  
provide more effective load balancing  
in certain configurations, such as routing  
data between multiple trunk groups  
for higher availability.  
Organizations can also use Brocade  
Advanced Performance Monitoring to  
improve SAN performance tuning,  
resource optimization, and administrator  
productivity. Moreover, the Brocade  
Fabric Access API integrates with  
popular third-party storage management  
applications, enabling organizations to  
continue using their storage manage-  
ment tools of choice.  
and control processors, and can intermix  
SilkWorm 12000 and SilkWorm 24000  
blades in supported configurations.  
In addition, the SilkWorm 24000 is  
designed to support non-disruptive  
addition of 4 Gbit/sec Fibre Channel  
blades for performance and distance  
benefits. These capabilities help  
“future-proofthe SilkWorm 24000  
for years to come. (For specific

FICON SUPPORT FOR IBM ZSERIES  
SERVER ENVIRONMENTS  
SilkWorm 24000 with new 4 Gbit/sec  
blades enables unprecedented distances  
between servers and storage devices.  
Support for distances up to 500 kilo-  
meters at 1 Gbit/sec and 100 kilome-  
ters at 4 Gbit/sec at full bandwidth  
facilitates high-performance, long-  
distance SAN solutions for data  
The SilkWorm 24000 supports the  
FICON protocol for IBM zSeries server  
environments, enabling organizations  
to run both open systems Fibre Channel  
and FICON traffic in intermix mode  
on a port-by-port basis within a single  
director.The Brocade FICON imple-  
mentation also supports cascaded  
FICON fabrics and both 1 and 2  
Gbit/sec FICON speeds, as well as the  
CUP in-band management protocol  
for use with SA/390, DCM, or RMF  
monitoring platforms.  
MAXIMIZING SAN INVESTMENTS  
Brocade and its partners offer complete  
SAN solutions to meet a wide range of  
technology and business requirements.

replication and business continuance.  
INTELLIGENT SAN MANAGEMENT  
AND MONITORING  
The SilkWorm 24000 leverages Fabric  
OS, the embedded operating system,  
to centralize SAN management for  
greater efficiency.This approach enables  
heterogeneous device connectivity, auto-  
matic data routing, self-healing capabili-  
ties, and scalable connectivity options.  
To simplify daily SAN management,  
organizations can utilize a command line  
interface for automated scripting or the  
GUI-based Brocade Web Tools utility.
