Brocade Communications Systems SilkWorm 24000 User Manual

The Brocade SilkWorm 24000 Director provides

a highly reliable and intelligent solution for

enterprise-class Storage Area Networks (SANs)

in mission-critical environments.

With state-of-the-art performance
and enhanced scalability for both
open system and IBM zSeries server
enterprise SAN environments, the
Brocade®SilkWorm®24000 Director
provides unique capabilities to meet
demanding mission-critical require­ments. It scales non-disruptively
from 32 to as many as 128 concur­rently 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 perform­ance 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.

With its intelligent fourth-generation
ASIC, the SilkWorm 24000 provides
a reliable foundation for core-to-edge
SANs, enabling fabrics capable of

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 trans­action processing applications such as
ERP and data warehousing, as well
as data backup, remote mirroring,
and high-availability clustering.

The SilkWorm 24000 is designed to
integrate with heterogeneous envi­ronments 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).

SILKWORM 24000 DIRECTOR

SILKWORM SWITCH FAMILY

ULTRA-HIGH AVAILABILITY THROUGHOUT
THE FABRIC

The core-to-edge SAN model features
redundancy within the director as well as
a high-availability network approach for
the entire fabric.The ultra-high-availability
features of Brocade Fabric OS®help provide
a SAN infrastructure capable of delivering
continuous overall system availability with
features that include:

• Non-disruptive software upgrades and
hot code activation

• Dual-redundant control processors with
stateful failover

• Redundant, hot-swappable components and
redundant power and cooling subsystems

• Continuous monitoring of environmental
components

• Power-On Self-Test (POST), online/offline
diagnostics, and per-port statistics

• Error detection and fault isolation facilities

• Call-home capabilities to provide remote
notification of system events

A NEW LEVEL OF SAN SECURITY

To help protect valuable information, the
SilkWorm 24000 supports Brocade Secure
Fabric OS®, the most comprehensive fabric­based security platform available. Based on
the latest networking security technology,
Secure Fabric OS addresses a wide variety
of vulnerabilities within the SAN fabric and
helps prevent downtime due to human error.

INDUSTRY-LEADING PERFORMANCE

With a fully non-blocked architecture
supporting 128 ports concurrently active
at 2 Gbit/sec full-duplex, the SilkWorm
24000 supports the most demanding SAN
applications at the core of large SANs. It
employs a multistage shared memory
architecture that reduces latency in port-to­port transfers to 2.1 microseconds or less.

To provide even higher performance,
Brocade ISL Trunking with 2 Gbit/sec
blades combines up to four ISLs between
a pair of switches into a single, logical
high-speed trunk running at up to
8 Gbit/sec.With 4 Gbit/sec blades, an
ISL trunk can include up to eight ports for
as much as 32 Gbit/sec of data throughput.

core fabric surrounded by

cost-effective, highly scalable
enterprise SANs.

In addition, exchange-based Dynamic
Path Selection (DPS) optimizes fabric­wide 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.

To support disaster recovery and busi­ness continuance operations, the
SilkWorm 24000 with new 4 Gbit/sec
blades enables unprecedented distances
between servers and storage devices.
Support for distances up to 500 kilo­meters at 1 Gbit/sec and 100 kilome­ters at 4 Gbit/sec at full bandwidth
facilitates high-performance, long­distance SAN solutions for data
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, auto­matic data routing, self-healing capabili­ties, 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.

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 manage­ment tools of choice.

FICON SUPPORT FOR IBM ZSERIES
SERVER ENVIRONMENTS

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 imple­mentation 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.

UPGRADE PATHS FOR
INVESTMENT PROTECTION

To help protect existing technology
investments, the SilkWorm 24000 pro­vides backward and forward compati­bility with SilkWorm entry, midrange,
and director offerings. Organizations
can upgrade existing SilkWorm 12000
directors by replacing the port cards

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-proof” the SilkWorm 24000
for years to come. (For specific
SilkWorm 24000 upgrade options,
