Introduction
IBM offers a family of Fibre Channel switching products that allow
implementation of a storage area network (SAN) topology in Fibre
Channel Protocol (FCP) or fibre connection (FICON) environments.
IBM offers several alternatives to build a robust and scalable SAN
infrastructure that meets the customer’s data center requirements.
This manual provides information and procedures for installing the
SAN Router, and for configuring and managing by the SAN Router
Element Manager and the Enterprise Fabric Connectivity Manager.
The SAN Router Element Manager is a Web-based Java applet which
is used to configure, monitor, and troubleshoot the router.
SANvergence Manager is a Java-based collection of software tools for
managing a multi-protocol storage fabric consisting of McDATA
switches and gateways.
Both applications can be used to configure and manage the SAN
Router. SAN Router Element Manager is used to configure an
individual SAN Router while SANvergence Manager is used to
configure and manage multiple SAN Routers in a SAN environment.
When used with SANvergence, SAN Router Element Manager can be
launched from SANvergence.

SAN Router
The SAN Router (also referred to as router in this manual) supports
iSCSI, iFCP, and R_Port for connecting to both IP backbones and
legacy Fibre Channel (FC) fabrics. The SAN Router connects to a
wide range of Fibre Channel and IP end systems. The SAN Router
supports TCP/IP routing over extended distances at wire speed.
The SAN Router can be deployed for multiple, concurrent
applications, including SAN routing in the data center (mSAN
routing), SAN routing over distance (iSAN routing) for disaster
recovery, and iSCSI access to Fibre Channel storage.
mSAN routing enables you to build very large, stable fabrics where
faults in one part of the network do not impact traffic in other parts.
For disaster recovery, the backup site can be quite distant, thanks to
Fast Write technology, which can sustain wire-speed throughput in
spite of high-link latency. The TCP ports on the SAN Router can
support iSCSI access to Fibre Channel storage.
The SAN Router offers:
• mSAN internetworking for scalable and fault-tolerant SANs.
• Compression for increased bandwidth.
• Support for full fabric and private and public loop FC devices.
• Fast Write™ technology for maximizing throughput across long
distances.
The SAN Router is shown in Figure 1, The SAN Router, front view, and
described in SAN Router physical description. A rear view with power
supply locations is shown in Figure 2, The SAN Router, rear view.

Figure 2 The SAN Router, rear view
SAN Router physical description
All ports and connectors are located on the front of the SAN Router,
except for the power connectors, as described in the following
paragraphs. The rear of the SAN Router contains only the power
connectors and cooling fans. The Field Replaceable Units (FRUs) are
the optical transceivers, power supplies (which include internal fans),
and base machine.
Power
connections
There are two standard power connections located on the rear of the
SAN Router. Each of these power connections supplies AC power to
a different power supply for power redundancy and backup. Either
power supply can support the SAN Router operation, but it is
recommended that both be connected, each to a different power
source.
NOTE: If one power supply fails, the SAN Router will continue to operate
but the failed power supply should be replaced as soon as possible to retain
redundancy.
Fibre channel
ports
There are twelve user-configurable fibre channel ports located on the
front of the SAN Router, labeled 1 through 12. These port connections
hold SFP transceivers that support FC connectivity at 1 or 2 Gbps or
GE connectivity at 1 Gbps. The ports can be configured as:
• FC_Auto (default)
•FL_Port
• F_Port
• L_Port
• R_Port

Chapter 1: Overview
To the left of each FC port is an LED that indicates the configuration
and status of the associated port. For more information about these
LEDs, see Table 20 on page 52.
Intelligent ports
for IP connection
The SAN Router provides four intelligent ports for Gig Ethernet (GE)
connectivity, labeled 13 through 16. Each intelligent port for IP
connectivity can be configured for either Internet Small Computer
Systems Interface (iSCSI) or Internet Fibre Channel Protocol (iFCP).
Management ports There are two management ports located on the front of the SAN
Router. An RS-232 serial port that can be connected to a VT100
terminal emulator for access to SAN Router console that supports the
Command Line Interface (CLI), and an RJ45 port that can be
connected to the LAN for out-of-band management using the SAN
Router Element Manager or the SANvergence Manager. The RJ45
management port can be accessed by any PC on the LAN with a web
browser or Telnet based CLI.
Operational features
The SAN Router features are described in Table 3, SAN Router
features. Some features are optional and may not be present in some
SAN Router software versions.

Feature Description
Intelligent ports Four intelligent ports, which can be configured for
Internet Small Computer Systems Interface (iSCSI) or
Internet Fibre Channel Protocol (iFCP). An Intelligent
port is also referred as TCP port.
Internet Fibre Channel
Protocol (iFCP)
standards track
protocols
The SAN Router supports the IETF draft standard for
iFCP, which provides connectivity and networking for
existing Fibre Channel devices over a TCP/IP network.
iSCSI The SAN Router supports IETF standard based iSCSI
protocol.A TCP port can be configured for either iSCSI
or iFCP.

R_Port Support for FC-SW2 standard E_Port as well as
Brocade interoperability mode allows you to fully
integrate the SAN Router into an existing Fibre Channel
SAN that includes one or more Fibre Channel switches.
Fast write The Fast Write software feature available on intelligent
ports improves the performance of write operations
between Fibre Channel initiators and targets in a Wide
Area Network (WAN). The improved speed depends on
the WAN Round Trip Time (RTT), available buffer space
on the target, number of concurrent I/Os supported by
the application and application I/O size.
Router Zoning Using SANvergence Manager, network management
software, or the command line interface (CLI), you can
create zones across networks.
You can use zone sets for periodic reallocation of
network resources. For example, you can have one set
of zones for daytime data transactions and another set of
zones for nighttime backups. You can create zones
across networks.
Real-time and historical
system logs
The Element Manager and LogViewer can be used to
look at current system log messages from the connected
SAN Router.
Compression Compression technology available on intelligent ports
identifies repetitive patterns in a data stream and
represents the same information in a more compact and
efficient manner. By compressing the data stream, more
data can be sent across the network even if slower link
speeds are used.
Jumbo Frames Since the maximum Fibre Channel payload size is 2112
bytes, two regular Ethernet frames are required. The
Jumbo Frame option extends the Ethernet payload to
2112 bytes. With the support of Jumbo Frames, a Fibre
Channel frame can be mapped to just one Ethernet
frame, providing more efficient transport. For iSCSI
traffic, up to 4K size frames are supported.
