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 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.

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 trans-

action 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 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).

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 fabric-

based 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-to-

port 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 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.

To support disaster recovery and busi-

ness 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 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

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.

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.

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 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.

UPGRADE PATHS FOR

INVESTMENT PROTECTION

To help protect existing technology

investments, the SilkWorm 24000 pro-

vides backward and forward compati-

bility 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,
