Highlights

■

Designed for high performance

with 4 Gigabit per second

(Gbps) Fibre Channel (FC) ports

and hardware-assisted traffic

processing for line-rate per-

formance across Ethernet

Internet Protocol (IP) ports

■

Utilizes existing Internet, IP-

based Metropolitan Area

Network (MAN) or Wide Area

Network (WAN) infrastructures

for metro and global SAN

extension for business

continuity solutions

■

Hardware-based compression,

large window sizes and selec-

tive acknowledgement of IP

packets designed to optimize

performance of SAN extension

over IP networks

Integrated IBM System

Storage™ SAN b-type (Brocade)

switch management helps sim-

plify installation and administra-

tion and helps provide fabric

investment protection

A wide range of IBM System Storage

mid-range and enterprise Storage Area

Network (SAN) infrastructure simplifica-

tion and business continuity solutions

can be created with the IBM System

Storage SAN04B-R multiprotocol

router. Infrastructure simplification solu-

tions for the IBM Power™ Systems and

System x™ family include disaster tol-

erance over metropolitan and global IP

networks with IBM System Storage disk

arrays, tape libraries and IBM Tivoli®

Storage Manager data protection

software.

Local site infrastructure simplification

solutions may be extended to one or

more remote sites for enhanced data

protection and disaster tolerance. The

IBM System Storage SAN04B-R multi-

protocol router provides Fibre Channel

over IP and FCIP Tunneling Service for

distance extension which can enable

cost effective and manageable metro

and global business continuity solu-

tions. This extended distance connec-

tivity can help create consolidated

remote tape vaulting data protection

plus metro mirror and global mirror

disk-based disaster tolerant solutions.

High performance

The IBM System Storage SAN04B-R

multiprotocol router is designed to

deliver 4, 2 and 1 Gigabit per second

(Gbps) full-duplex Fibre Channel or

50 Megabit per second Ethernet line-

rate performance on all ports. Each

router FC port auto-negotiates to 4 or

2 or 1 Gbps depending on the speed of

the device at the other end of the link.

The Ethernet ports enable reliable SAN

extension across the Internet, IP-based

Metropolitan Area Networks (MANs)

and Wide Area Networks (WANs)

through the use of Fast Write,

hardware-based compression and

storage-optimized protocol

enhancements.

High-availability features

Mid-size SAN users require high-

availability fabric solutions. The

IBM System Storage SAN04B-R multi-

protocol router uses second-generation

advanced application-specific inte-

grated circuits (ASIC) electronic compo-

nents to help minimize the number of

components and improve reliability. The

SAN04B-R router is designed to pro-

vide hot-swappable, load-sharing dual

redundant power supplies that allow

the router to remain online if one power

supply fails. Dual power cords allow

attachment to separate power sources

for improved availability. Hot-swappable

power supplies and redundant cooling

fans help eliminate downtime for service

when replacing a failed component.

Hot-pluggable SFP transceivers are

designed to be replaced without taking

the router offline.

High availability solutions require redun-

dant components, including clustered

servers with dual Host Bus Adapters,

dual independent fabrics and disk stor-

age arrays with dual controllers each

with dual adapters. Dual IBM System

Storage SAN04B-R routers may be

configured in a high availability solution

to create a resilient “meta” SAN

infrastructure.

Configuration flexibility

A variety of SFP transceivers are avail-

able to meet diverse requirements.

Standard short wave optical Fibre

Channel SFPs are available to connect

at distances up to 1500 meters. Long

wave optical Fibre Channel SFPs are

available to connect at distances of up

to 4 km, 10 km or 30 km. Optical SFPs

are always used to connect the FC

ports to a Fibre Channel fabric, how-

ever both optical and copper SFPs are

available to connect the Ethernet ports

to an Ethernet fabric.

The router helps provide full Fibre

Channel fabric services with many stan-

dard features including WEBTOOLS

with Advanced Zoning, FCIP Tunneling

Service and Extended Fabric.

Fabric Operating System

Brocade® Fabric OS® (FOS) is

included with each SAN04B-R and

contains all functions necessary to

operate a base system. The SAN04B-R

requires FOS level 6.1.0 or higher. FOS

offers the following advanced functions:

●

ADVANCED PERFORMANCE MONI-

TOR helps identify end-to-end

bandwidth usage by host/target

pairs and is designed to provide for

capacity planning.

●

TRUNKING enables FC packets to be

efficiently distributed across multi-

ple ISLs between two IBM SAN

b-type fabric switches and directors

while preserving in-order delivery.

Both SAN b-type devices must have

trunking activated.
