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
hierarchica l set of pro tocol laye rs. Def ined with in
these layers are rules for signal interfaces, serial
encoding and decoding, error control, frame
format and communications protocols.

A SAN is a shared storage architecture connecting
computers and storage devices for online data
access. Each connected system can directly access
any attached storage device. Storage devices
could include RA ID , ta pe ba c k up , tape libr a ry,
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.

back using the "L"-brackets and mounting holes
provided on either end. The mounting holes on 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.

overheating and could damage the product.

Do not block the vents on either side of the

Internal power distribution

The ATTO FC Rack System provides a redundant
power scheme with two hot swappable power
supply modules. Each power supply 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 of the modules or the cooling 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 po wer module is a hot sw a p pab le un it th at
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, 47­63Hz, single phase. The AC input range selection

Connecting Fibre Chan nel 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 kno ws it is a part of a p ublic loop
connected to a fabric. If it does not, it knows it is
a part of a private loop consisting of other
NL_Ports on ly.

Arbitrated loops can have up to 126 active
NL_Ports but only one active FL_Port because the
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.

Y ou may not connect ports from multiple switches
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.

Cable length Cable type Cable size Connector

Up to 175 meters multimode fiber optic 62.5 micron LC
Up to 500 meters multimode fiber optic 50 micron LC
Up to 13 meters unequalized copper HSSDC-2

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.

3 Carefully slide the hub module out of the

6 Configuring the ATTO FibreCenter

The A TT O FibreCenter 34 00 ma y be con f ig ured 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.
Config u r a tio n is ma naged through a 10 /100 Ba seT E th erne t 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-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. 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 labe le d w it h le t te r s .

❈

Zone 2 and Zone 3 do not overlap.

❈

Within a zone, all ports are disabled except
the lo west-numbe red port (cou nting from th e
left) and the single other port to which it is
switched.

Data transfer when setting up zones

Y ou must temporarily stop data transfer to the hub
when you execute the Setup and Switch
commands during setup of the A TTO FibreCenter .

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 dual­zoned configuration, you must temporarily
stop all data transfers from the host to the
FibreCenter.

❈

If you are changing zone 2 setup in a dual­zoned 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.

9 Troubleshooting

The fault LED indicates that a signal is being received, but the signal contains enough faults to make
the port fail and go into bypass mode.

Port LEDs on the ATTO FibreCenter are
generally lighted if the port is enabled through the
Setup CLI command and an active device is
connected to the port. However , if you want to test

Forcemode while in the command line interface.
If the FibreCenter is not in force mode, however,
the port LEDs will behave as illustrated in the

table below.
your configurations without having active devices
attached to the ports, enter the command Switch-
