Laser Safety Information

This product may use Class 1 lasers to communicate over the fiber optic conduc­tors. The U.S. Department of Health and Human Services (DHHS) does not
consider Class 1 lasers to be hazardous. The International Electrotechnical
Commission (IEC) requires labeling information that states that the lasers are
Class 1.

Labeling Requirements

There are no caution or danger labels required for use of the optical Gigabit Inter­face Converter (GBIC) since it is a Class 1 laser component assembly. Within the
U.S., the only laser safety label required is the certification label that already
appears on the plastic retainer of the optical GBIC assembly. Outside of the U.S.,
the IEC 825 laser safety standard requires that the system level product have a
Class 1 information label permanently attached and clearly visible whenever
access to the optical ports is possible. This label is supplied with the equipment
and applied by the user during the installation procedure. Refer to Section 2 Instal-

lationl. An example of the IEC Class 1 information label and its dimensions,

suitable for use in most European countries, is shown below. The label consists of
black printing on a yello w background. The languages represented on this e xample
label are English, German, Finnish, and French and represent the minimum set for
acceptance of a Class 1 product in most European countries.

Section 1 General Description

Introduction

The SANbox™-16HA High Availability Fibre Channel (FC) Switch is the Fabric
component of a Fibre Channel compliant network. Figure 1-1 is an illustration of
the Switch. This manual describes the Switch as a full-featured fabric Switch
unless otherwise specified.

Major Fibre Channel Port Features

Major Fibre Channel Port Features

Major Fibre Channel port features include:

• Each Switch chassis has 16 Fibre Channel ports. Each port operates at

1062.5 megabaud.

• Any or all 16 ports may be:

Fabric Ports Fabric ports connect to fibre channel public devices and device

loops. A fabric port is self configuring as an F_Port for a public device
or as an FL_port for a loop of public devices. Refer to “Fabric Port

Overview” on page 1-3.

SL_Ports Segmented Loop Ports (SL_Ports) allow you to divide a Fibre

Channel Private Loop into multiple se gments. Each segment of the loop
can pass frames around as an independent loop and can also connect
through the fabric to other segments of the same loop. Refer to

“Segmented Loop Port (SL_Port) Overview” on page 1-3.

TL_Ports. Each Translated Loop Port (TL_Port) connects to a private loop

and allows connectivity between the private loop devices on the loop
and “off-loop” devices (devices not connected to that particular
TL_Port) such as Public fabric devices and private devices on other
TL_Port loops. Refer to “Translated Loop Port (TL_Port) Overview”

on page 1-6.

T_Ports. Trunk P orts (T_P orts) allow the interconnection of multiple chassis

to form larger fabrics. Refer to Section 5 Multi-Chassis Fabrics.

• All ports support Class 2 and Class 3 Fibre Channel service. Refer to Appen-

dix A Reference Information for more information.

• The Switch supports the maximum Fibre Channel frame size (2148 bytes) for
Class 2 and 3 Fibre Channel service. Refer to Appendix A Reference Infor-

mation for more information.

• All ports are supported by GigaBit Interface Converters (GBICs). GBICs
contain the transmitters and receivers that connect to the interconnection

Preliminary

media. Each GBIC is “hot pluggable”.

• Each port has eight buffer credits. This feature allows a cable length up to 13
km at 1 Gbps without performance degradation. F_Port and T_Port credits
can be extended by chaining ports together. Refer to “Port Buffer Credits” on

page 2-10 for more information about extending port credits. Cable length is

also dependant on the type of GBIC used. Refer to Appendix A Reference

Information for more information.

SANbox-16HA Fibre Channel Switch

1-2 General Description 59005-03 Rev. A Installer’s/User’s Manual

• You may populate 2 to 16 ports with GBICs. The choice of ports and GBICs
is yours.

The Switch has been validated with GBICs that support a variety of intercon­nection media. Refer to “Fibre Channel Ports” on page 1-17 for more infor-
mation.

Fabric Port Overview

All ports on the SANbox-16HA chassis are “Loop-aware” FL_Ports. That is, they
are ports that are able to discov er, through the Fibre Channel Fabric Login process,
whether they should function as an F_P ort (communicating with an N_P ort) or as a
Fabric Loop port (communicating with an Node Loop Port (NL_Port)). Fabric
ports connect to Public devices that conform to the Fibre Channel Standards.

Switch management allows you to force a fabric port to function as an F_Port.
Refer to the Switch Management manual for more information.

The attributes of F_Ports and FL_Ports are described in the Fibre Channel
Standards.

Segmented Loop Port (SL_Port) Overview

You may use Switch management to configure any or all ports on the SANbox-16
chassis as Segmented Loop ports (SL_Ports). SL_Ports connect to devices which
conform to the Fibre Channel-Private Loop SCSI Direct Attach (FC-PLDA)
standard. SL_Ports allo w y ou to divide these Private Loops into multiple se gments
which may communicate through the Switch as though they were all part of the
same Private Loop.

Major Fibre Channel Port Features

A Segmented Loop has greater performance than an un-segmented loop because a
Segmented Loop can have multiple concurrent frame transfers (one per loop
segment) while an un-segmented loop can have only one.

Figure 1-2 sho ws a possible topolo gy of a Segmented Loop. In this figure, there are

three distinct loop segments that have been linked (placed in the same segmented
loop zone) together by the Switch as a single Se gmented Loop. This means that all
three loop segments share the same address space (same set of Arbitrated Loop
Physical Addresses (AL_PAs)). All devices on the Segmented Loop can see all
other devices as though they were attached to their local loop segment.

• Each SL_Port can support up to 126 devices.

• Each SL_Port automatically discovers the devices connected to it.

• Switch management allows you to link up to 32 segments (SL_Ports)
together in the same segmented loop zone (even across multiple chassis in
the same fabric) to form a Segmented Private Loop. The aggregate total
number of devices in the linked SL_Ports must not exceed 126 devices and
all AL_PAs within the linked segments must be unique.

Switch management allows you to define a chassis as an SL Private Loop stage
type. This stage type defines all ports on the chassis as SL_Ports and links them
into one segmented loop. If an SL Private Loop chassis is to be used in a cascade

Preliminary

topology, all chassis in that topology must also be SL Private Loop. Furthermore,
an SL Private Loop chassis in a multi-chassis fabric will force all other chassis in
that fabric to behave as SL Pri v ate Loop chassis. You may not mix SL Priv ate Loop
chassis with other stage types in the same fabric.

You define an SL Private Loop chassis by selecting SL Private Loop as the stage
type in the Chassis Parameters portion of any Switch Faceplate Display in the
SANSurfer Switch Management application. Refer to the Switch Management
manual for more information.

Major Fibre Channel Port Features

Translated Loop Port (TL_Port) Overview

You may use Switch management to configure any or all ports on the SANbox-16
chassis as Translated Loop ports (TL_Ports). TL_Ports connect to devices which
conform to the Fibre Channel-Private Loop SCSI Direct Attach (FC-PLDA)
standard. Each TL_Port allows connectivity between the Private Loop devices on
the loop and “off-loop” devices (devices not connected to that particular TL_Port)
such as Public devices connected to F and FL_Ports and private devices on other
TL_Port loops. This connectivity is achieved by having a translation function at
each TL_Port which translates Private frames to Public frames and vice versa.

Figure 1-3 shows possible Fabric topologies with both public and Private SCSI

devices. In this figure, the TL_Ports are ports with Translation Mode functions.
The following three scenarios are supported by TL_Ports:

• Server 1 to ST1 (Public Initiator to/from Private Target)

• Server 2 to ST2 (Private Initiator to/from Public Target)

• Server 3 to ST3 (Private Initiator through fabric to/from Private Target on
different loop)

TCP/IP protocols are also supported. Figure 1-4 shows possible topologies for
TCP/IP:

• Server 1 to and from Server 2 (Public device to/from Private device)

• Server 3 to and from Server 4 (Private device through fabric to/from Private
device on different loop).

When one of these AL_PA addresses communicates with an “off-loop”
device, the TL_Port acts as a proxy for the off-loop device on the Private
Loop. This means that the TL_Port handles all loop primitives on behalf of
the off-loop device.

• Each TL_Port may proxy up to 31 off-loop devices. These off-loop devices
must be Public devices (connected to F, or FL_Ports) or Private devices on
other TL_Ports.

Installer’s/User’s Manual 59005-03 Rev. A General Description 1-7

Major Fibre Channel Port Features

• The set of off-loop devices that a single TL_Port may proxy may overlap or
exclude the devices accessed by other TL_Ports in the same fabric.

• The set of off-loop devices proxied by a TL_Port is contained in its transla­tion entries list.

The translation entries list for a TL_Port connected to Private targets will
contain the initiators (both Public and Private) that try to communicate with
those targets. An Auto Learning feature automaticall y adds these initiators to
the ports’ translation entries list. Use Zoning to limit the number of initiators
to 31 or less. You may disable Auto Learning for any TL_Port via Switch
management. The default for each TL_Port is Auto Learning enabled.

The translation entries list for a TL_Port connected to Priv ate initiator s will
contain the targets (both Public and Private) that you want the Private initia­tor to communicate with. Auto Learning is not able to enter these tar gets into
the translation entry list. The translation entries list cannot exceed 31 entries.
Switch management allows you to manage the translation entries list for
these TL_Ports. Auto Learning should be disabled for these TL_Ports
connected to Private initiators.

• You may disable Auto Learning for any TL_Port via Switch management.
The default for each TL_Port is Auto Learning enabled.

• Devices on TL_Ports cannot communicate with devices on SL_Ports.

• TL_Ports support Broadcast.

• Multiple TL_Ports can coexist in a single fabric. They may be zoned to
control access.

• Devices connected to TL_Ports are registered with the Name Server.

• The user must identify Public Targets and Initiators for each TL_Port.

• TL_Ports support all SCSI/FCP frames.

NOTE:

Preliminary

Third Party SCSI commands (i.e. Third Party RESERVE, COPY, XOR) are
not supported. A Third Party SCSI command is any command that has a
target address embedded in the command (i.e. embedded in the Fibre
Channel frame payload).

• TL_Ports support TCP/IP.

Major Switch Chassis Features

The following is an overview of the major features of the Switch chassis:

• A chassis can be defined as one of three stage types: Input/Output Transfer
(IO/T), Cross Connect (CC), or SL Private Loop. An IO/T chassis supports
all port types (F, FL, SL, TL, and T). A CC chassis supports only T_Ports as it
serves as a bridge between many IO/T chassis. An SL Private Loop chassis
supports SL_Ports and T_Ports. Refer to“Three Multi-Chassis Topologies”

on page 5-2 for more information about IO/T and CC stage types. Refer to

Preliminary

“SL Private Loop Stage Type” on page 1-5 for more information about the

SL Private Loop Stage Type.

• You have the option to add a second power supply for total power supply
redundancy. When there are two power supplies, they each become “hot
pluggable”. Refer to “Power Supply(s)” on page 1-24 and also to Section 4

Removal/Replacement Procedures.

SANbox-16HA Fibre Channel Switch
Installer’s/User’s Manual 59005-03 Rev. A General Description 1-9

Major Switch Chassis Features

• Each chassis has two separate AC power inputs, one for each power supply.
The left AC power input provides input power to the left power supply. The
right AC power input provides input power to the right power supply.

• The Switch performs Power-On-Self-Tests (POSTs) each time it is powered­up. POST provides one pass through the battery of tests, but does not test the
GigaBit Interface Converters (GBICs). The POST uses the Heartbeat LED to
indicate pass or fail test conditions. Refer to “Heartbeat LED (Yellow)” on

page 1-20 and“Power-On-Self-Test (POST)” on page 3-6.

• LEDs indicate the status of the Switch and each port. Refer to“Front Panel

LEDs” on page 1-20.

• The Switch contains an RJ-45 Ethernet connector that provides a manage­ment connection to the outside world. The user can use a management station
connected via this network to manage the Switch. Refer to “Major Switch

Management Features” and “Switch Management Connector” later in this

section, and the Switch Management manual for more information.

• The Switch chassis may be connected to other Switch chassis to expand the
number of user ports. Refer to Section 5 Multi-Chassis Fabrics for more
information.

• The Switch chassis is shipped from the factory physically configured with
rubber feet on its bottom that allow it to sit on a flat surface and stack.
Mounting brackets (in a separate packet shipped with the Switch) allow you
to mount it in a 19-inch rack. When mounted in a rack, the Switch must be
supported by rails or a shelf. Refer to Section 2 Installation for the install
procedure and to Appendix A Reference Information for the dimensions and
type of rack.

• SANbox switch fabrics support the use of MKII switches as IO/T chassis in
mesh and Multistage™ topologies. Refer to “Three Multi-Chassis Topolo-

gies” on page 5-2 for more information about MKII compatibility.

Major Switch Management Features

• Perform Trace operations to follow selected operations through the selected
chassis

• Read and write memory locations on the selected chassis

• Update the Flash memory on the selected chassis

• Divide the ports or devices into zones for more efficient and secure commu­nication among functionally grouped nodes.

Hard Zones

Hard zones allow the di vision of the fabric (one or more Switch chassis) into
as many as 16 fabric-wide zones that define the ports that may communicate
with each other. A port may communicate with any other port that is in the
same hard zone as it is defined. If hard zones cross chassis boundaries in a
multi-stage topology, the interconnecting T_Port, or ports must be placed in
the same hard zone that they interconnect. Refer to Section 5 Multi-Chassis

Fabrics. A particular F, FL, TL, or T_Port may be placed in only one hard

zone (no ov erlapping hard zones). If hard zones are enab led, broadcast zones
and Name Server zones do not cross the defined hard zone boundaries.

Broadcast Zones

Broadcast zones allow the di vision of the fabric into as many as 16 zones that
define the ports that receive Broadcasts. A particular F, FL, or TL_Port may
be placed in one or more of these broadcast zones. A port will broadcast to all
ports in the same broadcast zone (or zones) in-which the port is defined. If
hard zones are enabled, broadcast zones do not cross the defined hard zone
boundaries. Broadcast zones may o v erlap each other . T_P orts are not af fected
by broadcast zones.

Name Server Zoning by Port

Name server zoning by port allows the division of the fabric into as many as
256 zones that define the ports that receive Name Server information. A
particular F, FL, or TL_Port may be defined in one or more of Name Server
zones. A port will receive Name Server information for all zones of which it

Preliminary

is a member. If hard zones are enabled, Name Server zones do not cross the
defined hard zone boundaries. Name server zones may overlap each other.
T_Ports are not affected by Name Server zones.
