Fibre Channel Configurations

Fibre Channel Configurations

The Fibre Bridge is supported in a basic configuration on Digital Linear
Tape (DL T) and Magneto-Optical (MO) libraries. The bridge is support in
expanded configurations on DLT libraries. A basic configuration is
comprised of only one Fibre Bridge (two SC SI buses available) and a
host. Expanded configurations may include multiple hubs and hosts,
usually connected to one or more networks.

Basic Configuration

Figure 1-1 shows the Fibre Bridge in a basic configuration, including one
host or server, one Fibre Bridge, and one library.

NOTE Magneto-optical libraries are supported only on the basic configuration.

You may connect a maximum of two MO libraries (one on each SCSI bus
from the bridge).

Mounting the Fibre Bridge in a Rack

Assemble the L-brackets to the Fibre Bridge

1. Facing the back of the Fibre Bridge, position the first L-bracket with
the mounting tab toward the back of the rack and pointing away from
the unit, as shown in Figure 2-1.

2. Insert 6x32 screws through the first and third holes from the
mounting tab and tighten. Use the first and third holes (from the
mounting tab end of the bracket) for mounting in a Hewlett-Packard
rack. (Non-HP racks may require mounting holes number two and
four. See note below.)

3. Follow the same procedure for the second L-bracket.

NOTE For non-HP racks, allow for cable turn: A minimum distance of 5 inches

(125 mm) is required between the back of the Fibre Bridge and the
backplane of the rack. When installing in racks where the mounting
holes in step 2 produces a distance less than 5 inches (125 mm), use the
second and fourth holes when attaching the mounting bracket to the
Fibre Bridge.

Installing Cables

Installing Cables

The Fibre Bridge can be used in either basic or expanded system
configurations. This section provides the steps to install cables in both
configurations.

NOTE The following section explains overall configuration cabling. For

complete installation procedures, refer to the INSTALL subdirectory on
the CD-ROM shipped with the bri d ge.

Fibre Bridge Connection, Basic Configuration Example (DLT and MO Libraries)

CAUTION Be sure all devices in the configuration have been turned off and

disconnected from the power source before making any connections.
F ailure to disconnect all power could result in damage to the devices.

1. Properly shut down all peripheral devices that will be connected to
the Fibre Bridge, i ncluding the host. If the host compu ter is connected
to a network, check with the system administrator before switching
off power.

2. Connect the SCSI cable from bus 1 on the Fibre Bridge to bus 1 on the
library.

For a two-drive DLT library, connect a SCSI cable from bus 2 on the
Fibre Bridge to bus 2 on the library.

For a two-bus MO library, connect a SCSI cable from bus 2 on the
Fibre Bridge to bus 2 on the library.

NOTE A basic, point-to-point configuration is “One HBA to one bridge to one or

two SCSI buses.”

A two-drive DLT library uses both SCSI buses, so only one t w o-drive
DLT library may be connected to one HBA.

An MO library may be connected to each SCSI bus on a bridge, so two
MO libraries (maximum) may be connected to one HBA.

2-6 Chapter 2

Setting Up the Fibre Bridge

3. Connect one end of the optical cable into the GBIC on th e Fibre
Bridge and the other end into the GBIC on the Fibre Channel HBA in
the host.

4. Connect the power cord from the Fibr e Bridge to an grounded outlet.

5. Confirm that all cable ends are connected securely and both ends of
the SCSI bus are properly terminated, as shown in F igure 2-3 on p age
2-7.

6. Go to “Powering on the System” in Chapter 3.

library one. For a two-drive library, connect a SCSI cable from bus 2
on the Fibre Bridge to bus 2 on the library.

3. Connect the optical cable from the Fibre Bridge to the hub.

4. Connect an optical cable from the hub to each host syste m.
If you have a 6-8 host system, you will need an additional hub. (See

Figure 2-3 and Figure 2-4 for examples of expanded configurations.)

5. Connect the power cord from Fibre Bridge one to an grounded outlet.

6. Confirm that all cable ends are connected securely and both ends of

Powering on the System

Powering on the System

The HP SureStore Fibre Channel SCSI Bridge 2100 ER is configured for
most Fibre Channel installations without intervention. The basic
configuration uses one Fibre Bridge connected directly to a Fibre
Channel Host Bus Adapter (HBA) within a host computer. In expanded
configurations (DLT libraries only), the Fibre Bridge may be connected to
either a Fibre Ch annel HBA or a Fibre Channel hub . Th e F ibre Bridge is
set up to support an HP single-ended SCSI library on a Fibre Channel
arbitrated loop.

Use the following sequence when powering on the sys tem:

NOTE Powering on each device in the proper sequence is important. When

devices are turned on out of order, communication failures may result.

1. Power on the library, which allows the Fibre Bridge to connect
properly to the library when it scans the SCSI bus.

2. Power on the F ibre Bridge. When you do, notice that the power
indicator comes on immediately. The Fault indicator may flash
momentarily. After about 30 seconds, the SCSI activity indicator will
flash once. The Fibre Channel activity indicator will not flash until
other devices have been attached and powered on.

3. Power on the hub, if required.

4. Power on the host.
(If DLT) If there are multiple hosts , power them on sequentially.

Order is important. Wait for for each host to finish booting before
powering on the next host.

NOTE If any fault indicators are encountered on the Fibre Bridge or other

equipment, consult the appropriate user gui de.

5. (If DLT) Install backup software.

Operating the Fibre Bridge

Changing the Default Settings

Changing the Default Settings

The basic Fibre Bridge configuration assumes there is only one Fibre
Bridge included in the system. If this is a DLT installation and more
than one Fibre bridge will be installed, or if there is another Fibre
Channel device using the same address, you must change the fib re
channel address, using the serial port of the Fibre Bridge.

Connecting the Serial Cable

Using the serial cable is not necessary in most installations. The default
settings work in most configurations. Use the serial cable only if one of
the following situations occurs:

• The default configuration must be changed.

• A failure has occurred that requires diagnostic procedures. See
“Chapter 4: Troub les h o ot ing.”

If any of these scenarios occur , attach the serial cable and RJ-11 to DB9
adapter as shown in Figure 3-2 on page 3-6.

Operating the

Fibre Bridge

1. Plug the RJ-11 connector into the Fibre Bridge.

2. Plug the DB9 adapter into the Com1 or Com2 port of the computer.

3. Verify that the RJ-11 serial cable is properly plugged into the RJ-11
to DB9 adapter.

Serial Port Setup

Before communicating, the PC serial port must be connected to t he Fibre
Bridge and terminal emulation software (Hyperterminal, or similar)
must be installed on the ho st. Configure t he terminal emulat ion program
to use the settings in Table 3-1 on page 3-8 for the PC’s serial port.

NOTE When initially powered on, the Fibre Bridge uses the default (or

previously set) baud rate during self-tests. After completing the
self-tests, pressing
itself to the baud rate used by the host.

ENTER several times causes the Fibre Bridge to reset

Serial Port Operation

The serial port on the Fibre Bridge connects to a terminal or computer
that is running a terminal emulator such as Hyperterminal on Windows
NT. The operator can then perform the following:

• Change the system addresses and address modes

Fibre Bridge

• Check the results of the POST tests

• Change the operating leve l of diag nos tic rout in es

NOTE The serial port cannot be used to transfer data to devices on the SCSI

buses or on the Fibre Channel loop.
An EEPROM inside the Fibre Bridge stores configuration changes.

Because the Fibre Bridge stores its original settings, it can be reset to the
original configuration at any time. See Table 3-1 on page 3-8 for the
default configuration settings.

NOTE If there is trouble communicating between the serial port and the Fibre

Bridge, contact an HP service representative.

• Termination: Problems with termination can cause intermittent or

hard failure. Two connectors are implemented for each SCSI bus,
supporting middle of bus configurations.

Terminate the SCSI bus on both ends, and only at the ends of the
bus. Check each terminator and connector for bent pins.

• Bus Type: Single-ended devices cannot be combined with

differential de vices on the same bus. Similarly, differenti al
terminators cannot be used on the single-ended Fibre Bridge.

• Device ID: Each device on a SCSI bus must have a unique ID. The

default SCSI ID of the Fibre Bridge is 7. Make sure that this ID is
not in use on the bus. Check the library user guide for the default
SCSI IDs. Verify that other IDs on the bus are not in conflict.

• Cabling: Check SCSI cables to verify that they are functional, then

perform the following procedures:
a. Be sure the maximum cable length on the single-ended SCSI

cable connected to the F ib re B rid ge does not exc e ed a to ta l of 3

Fibre Channel Overview

Defining Fibre Channel

Defining Fibre Channel

This overview of Fibre Channel is intended to briefly explain the
technology, its potential uses, and possible problems that a user should
consider. Individuals requiring more information should consider
additional publications, seminars, and Fi bre Channel user groups.

Fibre Channel is an information transport protocol that can be used to
send information between computers and computer sub-systems.
Defined by the American National Standards Institute (ANSI), Fibre
Channel supports the following:

• Internet Protocol (IP)

• Transmission Control Protocol/Internet Protocol (TCP/IP)

• Small Computer System Interface (SCSI)

• High-Performance Parallel Interface (HIPPI)

• Asynchronous Transfer Mode (ATM)

• Other high-level protocols

Using Fibre Channel, these protocols can run at the same time. For
example, a host bus adapter (HBA) can simultaneously send Local Area
Network (LAN) information to another computer and read or write data
to a Redundant Array of Inexpensive Disks (RAID). Fibre Channel was
defined with multiple initiators in mind. In addition to supporting a
number of protocols on the same connection, Fibre Channel offers users
the following advantages:

• High speed data transmission

• Long distance support

• Large address space

• Multiple device configuration opportunities

Appendix A A-3

Fibre Channel

Overview

Fibre Channel Overview

Defining Fibre Channel

A fully implemented Fabric system supports over 16 million device
addresses, allowing a user to send data from each device at 100 MB per
second. Using fiber optic cable, Fibre Channel devices can be spaced at
maximum intervals of 10 km, supporting distributed hosts in a campus
environment, with centralized st orage systems. Fibre Channel uses
three connection topologies, illustrated in the following table:

A-4 Appendix A

Fibre Channel Overview

Implementing Fibre Channel

Implementing Fibre Channel

Whether designing a new system or enhancing a system that is in place,
Fibre Channel offers significant speed and distance and cost advantages.
Fibre Channel works with existing systems and software, with the
addition of a Fibre Channel HBA; new systems are not required to take
advantage of Fibre Channe l technology.

Distributed Devices

Computer and storage systems can be separated and distributed more
efficiently because of the distance capability of Fibre Channel.
Contrasting with the address range and distance limitations of SCSI,
adding storage with a Fibre Channel system does not require adding
servers, except when extra performance is needed.

Supporting distributed configurations, Fibre Channel improves dis aster
recovery planning. Faster speeds and greater transmission distances
allow for remotely located backup systems.

Cabling Advantages

Using less cable-associated hardware than a typical SCSI environment,
Fibre Channel reduces total system costs and supports greater
performance. Easily added, and often using LAN cables, Fibre Channel
cable is smaller and lighter than SCSI cable, making it easier to install
and manage.

Fibre Channel supports copper and optical cables. Optical cable, while
more expensive, will carry data further than copper and is not
susceptible to noise interference. Although current HBA drivers use
SCSI commands, future driver enhancements will support other
protocols specified for Fibre Channel, including LAN. Optical cables,
carrying LAN protocols, will be used in place of existing LAN cabling in
the future.

Appendix A A-5

Fibre Channel

Overview

Fibre Channel Overview

Working With Fibre Channel

Working With Fibre Channel

Fibre Channel is a transport protocol. Differing from protocols such as
SCSI, Fibre Channel does not use data manipulation commands. An
addressing scheme with advance handshaking requirements verifies
that data was transferred correctly.

Fibre Channel specifications are divided into multi-layered, functional
levels. The five layers define the physical media and transmission rates,
encoding scheme, framing protocol and flow control, common services,
and the upper-level protocol interfaces. Each section of the Fibre
Channel specification can be changed without affecting other sections.
Upper level specifications for Fibre Channel map commands and data
from different supported protocols to the Fibre Channel system. The
mapped commands and data are then segmented into frame sequences.
Each frame is encoded and sent to the desi red target device. At the target
device, the frames are decoded and reassembled into the original
sequence. The data in the sequence is extracted and then processed by
the target system. This whole process is done without knowledge of the
contents of the information being transferred.

Because Fibre Channel supports many different communication
protocols, the highest level of the Fibre Channel specifications identify
the type of communication protocol encoded. As information is divided
into sequences of frames, Fibre Channel attaches address and sequence
information to each packet. This transport protocol is required to
reconstruct the original information into its original form.

More complex than simply dividing information up into frames and
sending it to an address, Fibre Channel also has special frames to pass
the following Fibre Channel-specific information between devices:

• New devices added to the system

• All device addresses

• How and when data can be transferred

• Problem detection

A-6 Appendix A

Fibre Channel Overview

Working With Fibre Channel

The Fibre Channel protocol will work when devices are connected or
disconnected while data is being transferred because of this additional
information. Error detection and recovery at all levels of the protocol are
also provided.

A fairness algorithm is built into the FCAL protocol so that all devices
have equal access to the system. To keep the phase lock loops
synchronized, Fibre Channel continually communicates, even between
frames, supporting device arbitration for access to the loop. Fibre
Channel devices also use this communication to report on buffer size
available for communication. If there is nothing to report, the Fibre
Channel protocol fills up the space between frames with idle characters.
Characters must be present on the bus at all times to keep the high
frequency circuits working correctly, reconstructing data clocks and
detecting data on the bus. Even the data encoding is arranged so that
there is never a continuous string of ones or zeros.

The lower levels of Fibre Channel protocol is handled in the hardware
and, to a minor extent, by the low level HBA drivers. System and
application software does not need to be aware of any low level protocol
operations. Additional features exi st in the protocol that more advanced
applications can use.

Fibre Channel addressing int roduces three major advantages:

• Provides large number of addresses

• Detects address conflicts

• Automatically reassigns new addresses when conflicts occur

With Fibre Channel, the data network can be distributed and very large .
The ANSI Fibre Channel committee developed a method that devices
must use to check and report addresses before data can be sent or
received. ANSI also added the ability to semi-dynamically assign address
devices on the loop. Addresses are only checked and conflicts resolved
when a Fibre Channel device is added or removed. During normal
operations (i.e. no devices being connected or disconnected), device
addresses are not changed. When a Fibre Channel bus configuration
changes, each device on the bus verifies and reports its address.

Appendix A A-7

Fibre Channel

Overview

Fibre Channel Overview

Working With Fibre Channel

Fibre Channel devices may use either of two modes: soft or hard
addressing. Hard addressing is similar to the existing SCSI approach.
Fibre Channel device s can o nly us e t he assi gned a ddre ss. If that address
is already being used by another device, the Fibre Channel device will
not respond to any bus activity. Soft addressing is similar to LAN
addressing, where the system determines device addresses. As part of
the addressing protocol, all Fibre Channel devices have one or more
unique addresses that are not duplicated any where in the world. These
addresses are provided by ANSI to manufactures of Fibre Channel
products.

A-8 Appendix A

Fibre Channel Overview

Problems with Fibre Channel

Problems with Fibre Channel

Fibre Channel accommodates many protocols and physical interfaces.
Problems result in the attempt to do many things with one solution.
Awareness of the potential problems helps users create and maintain
reliable systems. This section addresses three of the main problems:

• Physical Connections

• Laser Power Control Systems

• Device Addressing

Physical Connections

Physical problems arise from connecting devices with different types of
cables. Fibre Channel supports copper and optical interfaces.

ANSI specifies types of copper cable. The maximum distance between
devices depends on the type of cable being used, but is limited to less
than 20 meters. As with all electrical media, Fibre Channel copper media
can radiate RF interference and can be affected by external RF noises.
Because of the distance limitation and noise problems, copper media
should be used only inside a cabinet or rack.

An optical interface should be used to send data farther. ANSI specifies
multiple optical interfaces that use lasers, light-emitting diodes (LED’s),
and different types of optical cable. Generally, cable that supports
greater distance transmission commands is more expensive than cables
that support shorter distances.

Using a Fibre Channel hub allows multiple cable types within a system.
For ex ample , all devices in a rack can be connect ed to a hub usin g coppe r
cable. The hub can be connected to a F ibre Channel l oop or Fabric using a
fiber optic cable.

Appendix A A-9

Fibre Channel

Overview

Fibre Channel Overview

Problems with Fibre Channel

Additional optical cable considerations are as follows:

• Cable between two nodes must use the same core size.

NOTE The limitation on mixing core sizes applies only to cable between two

nodes and is only a concern when splicing or connecting optical cables
directly together. Different size optical cable can be used in the same
Fabric between different sets of nodes.

• Three core sizes supported by Fibre Channel are: 62.5 micron, 50
micron, and 9 micron.

A-10 Appendix A

Fibre Channel Overview

Problems with Fibre Channel

Laser Power Control Systems

There are two types of systems approved for use: OFC and non-OFC.
These two types of control systems can exist on the same network, but
are not optically compatible and cannot be hooked up to the same optical
cable.

Device Addressing

The two modes of addressing use d in Fibre Channel, included on page
A-7, are hard and soft addressing. In small, controlled environments,
hard addressing works well. Also, s ome operating systems and host bus
adapters do not support soft addressing. Large Fabric networks,
connecting many devices, require the flexibility of soft addressing; hard
addressing is not supported in a Fabric environment.

HBA drivers cannot dynamically track device addresses that can change
after the system is turned on. Physical addresses change while the
operating system uses the same logical name for the device. Applications
that always use the same phy sical dev ice may use the World-Wide Name
(WWN). For ex ample, backup p rograms must locate the library and all of
its drives regardless of the bus address. Fibre Channel resolves these
issues.

Proper system pla nning a nd r ese arc h p rio r t o i nst all ing a F i bre C hannel
system will help avoid these problems. Configured properly, Fibre
Channel is as reliable and easy to use as current SCSI systems.
