1 Fibre Channel is a key technology for storage
Fibre Channel is a serial communications technology designed to transfer large amounts of data
between 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.
ASANisashared storagearchitecture connecting
computers and storage devices for online data
access.Eachconnectedsystemcandirectlyaccess
any attached storage device. Storage devices
could include RAID, tape backup, tape library,
CD-ROM library or JBOD.
SANs maintain greater fault tolerance and load
balancing by supporting server clustering and
failover (the ability for one server to take over for
another in the event of a failure).
The ATTO FibreCenter™ 3400 hub integrates
industry-leading performance and Storage Area
Network capabilities into mid-range applications.

Mounting
You can install the ATTO FC Rack System with
ATTO product modules facing the front or the
back using the "L"-brackets and mounting holes
providedon either end. Themountingholeson the
"L"-bracket fit a standard 19-inch rack, using a
centered 1.25-inch (31.7 mm) hole pattern.
Air flow and cooling
The FC Rack System cooling fans are contained
within the power module. Each power module
contains two 8-CFM fans and provides a total of
16 CFM of airflow. A system that has two power
modules installed will have a total of 32 CFM of
airflow. Air enters through the sides of the
enclosure and is exhausted out the power
modules. Ambient air near the inlets should not
exceed 40° C.
WARNING
Do not block the vents on either side of the
main enclosure. Blocking the vents may cause
overheating and could damage the product.
Internal power distribution
The ATTO FC Rack System provides a redundant
power scheme with two hot swappable power
supplymodules. Eachpowersupply module feeds
12V to the backplane. From there the power is
distributed to the FibreCenter 3400 modules and
the fans.
A failure of one power supply will not affect the
functionality ofthemodulesor thecooling system
since the second supply will continue to supply
power to the backplane. In a redundant power
supply installation, one supply can be removed
and replaced without affecting the rest of the
system in any way.
The product module will detect power supply
failures, voltage regulation and failover.
NOTE: Power modules will load balance
when two are present in the ATTO FC Rack
System
The power module is a hot swappable unit that
contains enough power to supply two ATTO
product modules and four cooling fans. Each is
designed to slide into the ATTO FC Rack System
enclosure in either of the two bays on the end of
the rack enclosure that is closer to the backplane
and farther away from the cooling vents in the
sides of the rack enclosure.
Input voltage:
110/230V AC, with an operating
input range of 90-132V AC or 175-264V ac, 47-
63Hz, single phase. The AC input range selection
is automatic. No manual jumper or switch over is
required.

Connecting Fibre Channel ports
The Fibre Channel ports connect into an
Arbitrated Loop.
When devices connected to the FibreCenter 3400
are powered up, each NL_Port must sign in with
the other ports on the loop. Each port first
attempts to find an FL_Port within the loop.
When it does, it knows it is a part of a public loop
connected to a fabric. If it does not, it knows it is
a part of a private loop consisting of other
NL_Ports only.
Arbitrated loops can have up to 126 active
NL_Portsbutonly oneactiveFL_Portbecausethe
FL_Port is considered the master. You may not
configure two switch ports (same switch or
different switches) because that would create two
FL_Ports.
The FibreCenter can connect direct to a fabric
switch, but the switch port must be configured as
an FL_Port (Loop Mode).
When connecting to a switch, make sure that only
one port of the FibreCenter 3400, or multiple hubs
daisy chained together, are connected to the
switch.
Youmaynotconnectportsfrommultipleswitches
to the same loop FibreCenter 3400.
Cabling
Fibre Channel technology offers a variety of
cabling options including standard copper,
equalized copper, multimode fiber optic, and
single mode fiber optic.
The FibreCenter 3400 uses a Small Formfactor
Pluggable (SFP) Fibre Channel interface.
The type of cable to use varies depending upon
the application, environment and distance. The
following table illustrates the different cable
options available.
Make sure all cables are anchored securely at both
ends with the proper connectors.
Removing the FibreCenter
1 Disconnect all cables from the face of the
hub module.
2 Loosen the two thumbscrews on the face of
the hub module.

6 Configuring the ATTO FibreCenter
The ATTO FibreCenter 3400 may be configured as one 8-port hub (Zone 1) or two 4-port hubs (Zone 2
and Zone 3). Each Fibre Channel bus in the two-zone configuration can run at different speeds (1Gb or
2Gb). The zones may be configured as either a one or two A-B style switch in a FC-AL loop.
Configuration is managed through a 10/100 BaseT Ethernet port.
The software necessary to drive the FibreCenter
3400 consists of two segments: the switching
logic and the command-processing logic.
The switching logic sets up hardware
configurations. The command-processing logic
allows you to change parameters on the
FibreCenter 3400 and view responses and other
information about the hub and its performance via
a Telnet server program and command line
interface commands (see Chapter 7.3)
The ATTO FibreCenter 3400 may be configured
as one 8-port hub (Zone 1) or two 4-port hubs
(Zone 2 and Zone 3) using the Setup and Switch
CLI commands. Each Fibre Channel bus in the
two-zoneconfigurationcanrunatdifferentspeeds
(1Gb or 2Gb). The zones may be configured as
either a one or two A-B style switch in a FC-AL
loop. A zone is defined by the following
parameters:
❈ A zone contains only adjacent ports.
❈ Except for the Get Switch command return,
Ports are labeled P1 through P8: all
connections are assumed to be between port
P1 and P2 | P3 | P4 | P5 | P6 | P7 | P8 in zone
1, between port P1 and P2 | P3 | P4 in zone 2
and between port P5 and P6 | P7 | P8 in zone
3. In the Get Switch command return, ports
are labeled with letters.
❈ Zone 2 and Zone 3 do not overlap.
❈ Within a zone, all ports are disabled except
thelowest-numbered port(countingfromthe
left) and the single other port to which it is
switched.
Data transfer when setting up zones
You must temporarily stop data transfer to the hub
when you execute the Setup and Switch
commandsduringsetupofthe ATTOFibreCenter.
Only the initiators can stop data transfer; the
FibreCenter cannot stop data transfers.
❈ If you are changing the FibreCenter 3400
from a single-zone configuration to a dual-
zoned configuration, you must temporarily
stop all data transfers from the host to the
FibreCenter.
❈ If you are changing zone 2 setup in a dual-
zoned configuration, but not changing zone
3, you must temporarily stop all data
transfers from the host in zone 2 but data
transfer may continue in zone 3.
❈ If you are changing from a dual-zoned
configuration to a single-zoned
configuration, you must temporarily stop all
data from the host to the FibreCenter.
FibreCenter behavior on reset or power-up
The ATTO FibreCenter takes about 40 seconds to
begin operation after power-up or execution of the
Reset command. All ports are disabled during this
40 seconds. When the FibreCenter begins
operation, it will use its default configuration or
the last mapping designated by the Setup and
Switch commands.
Zone 1
The FibreCenter 3400 may be configured into one
zone in which all eight ports are available. Up to
seven devices may access the eighth port, one at a
time.
Zone 2 and Zone 3
The FibreCenter 3400 may be configured into two
separate zones. In each zone, up to three devices
may access the fourth port in that zone, one at a
time. Devices in one zone may not access ports in
the other zone.
