2 Fibre Channel is a key technology for storage
Fibre Channel is a serial communications technology designed to transfer large amounts of data among
a variety of hardware systems over long distances. It is a key technology for applications that require
shared, high bandwidth access to storage.
Fibre Channel provides a logical, point-to-point,
serial channel for the transfer of data between a
buffer at a source device and a buffer at a
destination device. It moves buffer contents from
one port to another, without regard to the format
or meaning of the data so different upper level
protocols are able to run over Fibre Channel
hardware.
The Fibre Channel architecture is structured as a
hierarchical set of protocol layers. Defined within
these layers are rules for signal interfaces, serial
encoding and decoding, error control, frame
format and communications protocols.
Glossary
Some terms used in the Fibre Channel industry are defined below. More information is available through
the ATTO Technology web site ( www.attotech.com ) , the Fibre Channel Industry Association
( www.fibrechannel.com ) , Cern ( www.cern.ch ) , the Storage Area Networking Industry Association
( www.snia.org ) , and the Fibre Channel Consortium ( www.iol.unh.edu/consortiums , click on FC) .
Term Definition
ANSI American National Standards Institute
arbitrate process of selecting one L_Port from a collection of ports which ask for use of the arbitrated loop
at the same time
arbitrated loop a loop topology (FC-AL) in which two or more ports are interconnected, but only two ports can
communicate at one time; low-cost solution which may or may not use hubs and switches
auto negotiation hardware senses and automatically responds depending on configuration
BER Bit Error Rate: a measure of transmission accuracy; the ratio of bits received in error to bits sent
bit smallest unit of data a computer can process: a single binary digit with a value of either 0 or 1
bus a collection of unbroken signal lines used to transmit information from one part of a computer
system to another; taps on the lines connect devices to the bus
byte an ordered set of 8 bits
channel a point-to-point link which transports data from one point to another
CPU Central Processing Unit: the portion of the computer that actually performs computations
CRC Cyclic Redundancy Check: an error-correcting code which calculates a numeric value for received
and transmitted data; if no error has occurred during transmission, the CRC for both received and
transmitted data should be the same
destination
address
a value in the frame header of each frame which identifies the port in the node where the frame is
being sent
device driver a program that allows a microprocessor to direct the operation of a peripheral device
DMA Direct Memory Access: a way to move data from a storage device directly to RAM without using
the CPU’s resources
DMA bus master allows a peripheral to control the flow of data to and from system memory by block as opposed to
allowing the processor to control the data by bytes (PIO or programmed I/O)

10
fabric a Fibre Channel switch or two or more Fibre Channel switches interconnected to physically
transmit data between any two N_Ports on the switch or switches
FC Fibre Channel
F_port a port in the Fibre Channel fabric where a N_port may attach
FL_port a port in the Fibre Channel fabric where a NL_port may attach in an arbitrated loop
frame an indivisible unit for transfer of information in Fibre Channel
frame header the first field in the frame containing the address and other control information about the frame
full duplex a communication protocol which allows transmission in both directions at the same time
half duplex a communication protocol which allows transmission in both directions, but only one direction at a
time
host a processor, usually a CPU and memory, which communicates with devices over an interface
initiator device a component which originates a command
L_port a port in an arbitrated loop, either a NL_port or a FL_port
LED Light-emitting diode: a type of diode that emits light when current passes through it; visible LEDs
are used as indicator lights on all sorts of electronic devices
LUN Logical Unit Number: an identifier for a logical unit (0-7)
multi-mode fiber an optical fiber which can carry several beams of light at once
N_port a port attached to a node used with point to point or fabric configurations
NL_ port a port attached to a node in Fibre Channel arbitrated loop or fabric loop configuration
originator an initiating device; a component which originates a command

message occurs if the sum is not correct
PCI Peripheral Component Interconnect. Allows peripherals to be connected directly to computer
memory, bypassing the slower ISA and EISA busses

Term Definition

11 ATTO Technology Inc. Celerity FC Host Adapters Installation and Operation Manual
3 Hardware installation
You need a basic understanding of Fibre Channel before installing the Celerity FC host adapter. Please
refer to
Fibre Channel is a key technology for storage on page 9 for a list of related web sites.
CAUTIONCAUTION
Back up your system data before
changing or installing any hardware.
System requirements
The Celerity FC host adapter package contains the
host adapter, the ATTO Utilities CD and a
warranty and registration card. If any of these
items are missing, contact your ATTO authorized
sales representative.
To install and use the Celerity Fibre Channel host
adapter you need
• A computer with an available PCI, PCI-X or PCI
Express expansion slot.
• The complete Celerity FC host adapter package.
Fibre Channel address
Celerity FC adapters are configured with a unique
address designated by the Institute of Electrical
and Electronic Engineers. The WorldWide Port
Name (WWN) and Node Name are the two
components of the address assigned to Fibre
Channel products. This address, stored in flash
memory, allows the system to recognize the
Celerity host adapter as a unique part of your
configuration. The address is clearly marked on
the back of the board for easy identification.
Please keep a reference copy of the number in a
safe place or write in the space provided on this
page.
Celerity FC host adapter WWNs are assigned for
each channel. The WWN listed on your host
adapter is assigned to the first channel (0).
Sequential WWNs apply for additional channels.
Installation
CAUTIONCAUTION
Celerity FC host adapters contain
components that are sensitive to
electrostatic discharge (ESD). ESD can
cause damage to the Celerity FC host
adapter. Please follow standard methods
to avoid ESD.
1Power down the computer and unplug the
computer from all power sources.
2Open the case.
3Install the Celerity FC host adapter in any open
PCI, PCI-X or PCI Express expansion slot. If
you have questions about how to install an
expansion card in your system, consult your
computer’s documentation.
Note
The Celerity FC-24XL, FC-41XS, and FC-
42XS host adapters only fit in 3.3V slots.
The Celerity FC-44ES and FC-42ES (non
RoHS) fit in 8x or 16x mechanical PCI
Express slots.
The Celerity FC-42ES (RoHS) and FC-41ES
fit into 4x, 8x, or 16x mechanical PCI
Express slots.
If you have trouble seating your adapter in a
32-bit PCI bus computer, check to make sure
the connector can accommodate 64-bit host
adapters.
4Connect Fibre Channel devices by inserting a
Fibre Channel cable from the devices to the
connectors on the Celerity FC host adapter until
you hear a click.
5Close the case on the computer and power it
up.
