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 Installationl. 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 yellow background.

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 segments. 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 Ports (T_Ports) 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 Appendix 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 Information for more information.

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

1-2 General Description

 

SANbox-16HA Fibre Channel Switch

59005-03 Rev. A

Installer’s/User’s Manual

Major Fibre Channel Port Features

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 information.

Fabric Port Overview

All ports on the SANbox-16HA chassis are “Loop-aware” FL_Ports. That is, they are ports that are able to discover, through the Fibre Channel Fabric Login process, whether they should function as an F_Port (communicating with an N_Port) 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 allow you to divide these Private Loops into multiple segments which may communicate through the Switch as though they were all part of the same Private Loop.

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.

Major Fibre Channel Port Features

Figure 1-2 shows a possible topology 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 Segmented 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.

Segmented Loop Features

Switch management allows you to designate any or all ports on a SANbox-16 chassis as SL_Ports.

SL_Ports connect to devices that conform to the Fibre Channel-Private Loop SCSI Direct Attach (FC-PLDA) standard. If you place a Public Fibre Channel device on an SL_Port it becomes a Private device and (like other Private devices) cannot communicate off the loop.

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

1-4 General Description

 

SANbox-16HA Fibre Channel Switch

59005-03 Rev. A

Installer’s/User’s Manual

Major Fibre Channel Port Features

Devices in the same segmented loop zone communicate with one another as though they were on the same physical loop.

Devices on SL_Ports cannot communicate with devices on F, FL or TL_Ports. They also cannot communicate with devices on SL_Ports which are not in the same segmented loop zone.

Devices connected to SL_Ports are not registered with the Name Server.

Each loop segment may have a Fibre Channel Frame in process.

You may have as many loop segments as you have SL_Ports. That is, if none of them are zoned together, each SL_Port would contain one set of AL_PA and each AL_PA within that loop must be unique.

The Switch supports all SCSI/FCP and TCP/IP frames.

SL_Ports support Class 2 and 3 Fibre Channel Service.

SL_Port Management

Refer to the Switch Management manual for more information. The SANsurfer Web-based Switch management application provides the following:

The user may choose which ports (if any) are SL_Ports.

The user may place up to 32 SL_Ports together in the same segmented loop zone to form each Segmented Loop.

The application provides a map of all AL_PAs on a Segmented Loop. This viewable map includes information about which AL_PA address are being used by the SL_Port.

The application provides a way to flag error conditions to the user.

All management configuration information is stored in non-volatile memory.

SL Private Loop Stage Type

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 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 Private Loop chassis. You may not mix SL Private 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)

Translated Loop Features

Each TL_Port maintains up to 125 AL_PA addresses on the Private 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

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 automatically 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 Private initiators 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 targets 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:

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.

TL_Port Management

Refer to the Switch Management manual for more information. SANsurfer Switch management provides the following:

The user may choose which ports (if any) are TL_Ports.

The user may use Name Server Zoning or Hard Zoning to limit the number of Public devices that have access to a particular TL_Port to 31 devices or less.

The user may disable the Auto Learning feature for any TL_Port. The default for each TL_Port is Auto Learning enabled.

The user may manage the translation entries list for any TL_Port connected to Private initiators. That is, the user may identify all off-loop targets for the initiators on the particular TL_Port. Auto learning should be disabled for these TL_Ports.

SANsurfer provides a map of all AL_PAs on a Translated Loop. This viewable map includes information about which AL_PA addresses are being used by the TL_Port.

SANsurfer provides a way to flag error conditions to the user.

All switch management configuration information is stored in non-volatile memory.

The user may clear the stored configuration information.

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 “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.

59005-03 Rev. A

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

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

Hard Zones

Hard zones allow the division 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 overlapping hard zones). If hard zones are enabled, broadcast zones and Name Server zones do not cross the defined hard zone boundaries.

Broadcast Zones

Broadcast zones allow the division 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 overlap each other. T_Ports are not affected 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 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.

Name Server Zoning by World Wide Name

Name server zoning by world wide name (WWN) allows the division of the fabric into as many as 256 zones that define which devices receive Name Server information. A particular device may be defined in one or more Name Server zones. A device will receive Name Server information for all Name Server zones of which it 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.

Segmented Loop Zones

Segmented loop zones allow the division of the fabric into as many as 256 zones that define the SL_Ports that may communicate with each other. Each segmented loop zone can have a maximum of 32 SL_Ports, and each AL_PA within a segmented loop zone must be unique. You can zone individual SL_Ports together, or all SL_Ports on a chassis by defining the chassis as an SL Private Loop stage type. Refer to “SL Private Loop Stage Type” on

page 1-5 for more information. If hard zones are enabled, segmented loop zones do not cross the defined hard zone boundaries.
