Preamble

The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

General Public License

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and modification follow.

1.13.2

Terms And Conditions For Copying, Distribution And Modification

1.This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.

2.You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

3.You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such

1-10	59021-09 A

0	1 – Introduction
	General Public License

modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:

a.You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.

b.You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.

c.If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.

In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

4.You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:

a.Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,

59021-09 A

1-11

1 – Introduction	0
General Public License

b.Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,

c.Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.

If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.

5.You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

6.You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.

7.Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the

1-12	59021-09 A

0	1 – Introduction
	General Public License

rights granted herein. You are not responsible for enforcing compliance by third parties to this License.

8.If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

9.If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.

10.The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

11.Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this

59021-09 A

1-13

1 – Introduction	0
General Public License

License, you may choose any version ever published by the Free Software Foundation.

12.If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.

NO WARRANTY

13.BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

14.IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

END OF TERMS AND CONDITIONS

1.13.3

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.

To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names:

2.1.1

Power Switches

Each power supply has an On/Off switch that controls power to the switch logic circuitry. To apply power to the switch, place both switches in the On position.

2.1.2

Maintenance Button

The Maintenance button is a momentary switch on the front panel. Its purpose is to place the switch in maintenance mode. Maintenance mode sets the IP address to 10.0.0.1 and provides access to the switch for maintenance purposes when flash memory or the resident configuration file is corrupted. Refer to ”Recovering a Switch” on page 5-13 for information about maintenance mode.

To place the switch in maintenance mode, do the following:

1.Isolate the switch from the fabric. Open a Telnet session, and enter the Shutdown command. Refer to ”Shutdown Command” on page B-81.

2.Place both power supply switches in the Off position.

Fibre Channel Ports

2.1.3.3

Heartbeat LED (Amber)

The Heartbeat LED indicates the status of the internal switch processor and the results of the Power On Self Test (POST). Following a normal power-up, the Heartbeat LED blinks about once per second to indicate that the switch passed the POST and that the internal switch processor is running. In maintenance mode, the Heartbeat LED illuminates continuously. Refer to ”Heartbeat LED Blink Patterns” on page 5-2 for more information about Heartbeat LED blink patterns.

2.1.3.4

Input Power LED (Green)

The Input Power LED indicates the voltage status at the switch logic circuitry. During normal operation, this LED illuminates to indicate that the switch logic circuitry is receiving the proper DC voltages.

2.2

Fibre Channel Ports

The SANbox2-16 switch has 16 Fibre Channel ports numbered 0–15 as shown in Figure 2-4. Each of these ports is served by a Small Form-Factor Pluggable (SFP) optical transceiver. The port LEDs are located to the right of their respective ports and provide port login and activity status information. The ports self discover the proper mode when connected to public devices and other switches.

Figure 2-5. Port LEDs

2.2.1.1

Port Logged-In LED

The Logged-in LED indicates the logged-in or initialization status of the connected devices. After successful completion of the POST, the switch extinguishes all Logged-In LEDs. Following a successful loop initialization or port login, the switch illuminates the corresponding logged-in LED. This shows that the port is properly connected and able to communicate with its attached devices. The Logged-In LED remains illuminated as long as the port is initialized or logged in. If the port connection is broken or an error occurs that disables the port, the Logged-In LED will flash. Refer to ”Logged-In LED Indications” on page 5-6 for more information about the Logged-In LED.

2.2.1.2

Port Activity LED

The Activity LED indicates that data is passing through the port. Each frame that the port transmits or receives causes this LED to illuminate for 50 milliseconds. This makes it possible to observe the transmission of a single frame. When extending credits, the Activity LED for a donor port will reflect the traffic of the recipient port. Refer to ”Distance” on page 3-4 for more information about extended credits and donor ports.

Fibre Channel Ports

2.2.2

Small Form-Factor Pluggable (SFP) Transceivers

An SFP transceiver, like the one shown in Figure 2-6, converts electrical signals to and from optical laser signals to transmit and receive. SFP transceivers plug into the ports; duplex fiber optic cables plug into the transceivers which then connect to the devices. A port is capable of transmitting at 1-Gbps or 2-Gbps; however, the transceiver must be capable of 2-Gbps for the port to deliver at that rate.

The SFP transceivers are hot pluggable. This means that you can remove or install an SFP transceiver while the switch is operating without harming the switch or the transceiver. However, communication with the connected device will be interrupted. Refer to ”SFP Transceivers” on page 6-2 for information about installing and removing SFP optical transceivers.

Figure 2-6. SFP Transceiver

2.2.3

Port Types

SANbox2-16 switches support generic ports (G_Port, GL_Port), fabric ports (F_Port, FL_Port), and expansion ports (E_Port). Switches come from the factory with all ports configured as GL_Ports. Generic, fabric, and expansion ports function as follows:

A GL_Port self-configures as an FL_Port when connected to a public loop device, as an F_Port when connected to a single public device, or as an E_Port when connected to another FC-SW-2 compliant switch.

A G_Port self-configures as an F_Port when connected to a single public device, or as an E_Port when connected to another FC-SW-2 compliant switch.

An FL_Port supports a loop of up to 126 public devices. An FL_Port can also configure itself during the fabric login process as an F_Port when connected to a single public device (N_Port).

An F_Port supports a single public device. If the device is a single device on a loop, the GL_Port will attempt to configure first as an F_Port, then if that fails, as an FL_Port.

2-6	59021-09 A

0	2 – General Description
	Ethernet Port

E_Ports enable you to expand the fabric by connecting SANbox2-16 switches with other FC-SW-2 compliant switches. SANbox2-16 switches self-discover all inter-switch connections. Refer to ”Multiple Chassis Fabrics” on page 3-6 for more information about multiple chassis fabrics. Refer to the SANbox2-8c/16 Switch Management User’s Guide for more information about defining port types.

2.3

Ethernet Port

The Ethernet port shown in Figure 2-7 is an RJ-45 connector that provides a connection to a management workstation through a 10/100 Base-T Ethernet cable. A management workstation can be a Windows®, Solaris™, or a Linux®, workstation that is used to configure and manage the switch fabric. You can manage the switch over an Ethernet connection using SANsurfer Switch Manager, the Command Line Interface (CLI), or SNMP. The switch through which the fabric is managed is called the fabric management switch.

Power Supplies

The power supplies convert standard 110 or 230 VAC to DC voltages for the various switch circuits. Each power supply has an AC power receptacle, an On/Off switch, and two status LEDs as shown in Figure 2-9. After connecting a power supply to an AC voltage source and placing the power switch in the On position, the power supply is energized and DC voltage is delivered to the switch logic circuitry. Refer to Section 6 Removal/Replacement for information about replacing a power supply.

Figure 2-9. Power Supply Components

Each power supply is capable of providing all of the switch’s power needs. During normal operation, each power supply provides half of the demand. If one power supply goes offline, the second power supply steps up and provides the difference.

The power supplies are hot swappable and interchangeable. Hot swappable means that you can remove and replace one power supply while the switch is in operation without disrupting service.

Each power supply has two status LEDs: an Output Power LED (green) and an Over Temperature LED (amber):

The Output Power LED illuminates to indicate that the power supply is producing DC voltage at the proper levels.

The Over Temperature LED illuminates to indicate that the power supply is overheating. When a power supply overheats, the switch extinguishes the Output Power LED and shuts down the power supply. Refer to

Section 5 Diagnostics/Troubleshooting for information about troubleshooting over temperature conditions.

One instance of the web applet can be run at a time by opening the switch IP address with an internet browser. The switch comes from the factory with the web applet enabled, but you can disable it using the EmbeddedGUIEnabled parameter of the Set Setup System command. An inactivity timeout can also be set. Refer to ”Set Setup Command” on page B-49 for more information.

The applet possesses the same features as the workstation-based version with the following exceptions:

Command Line Interface

The command line interface (CLI) provides monitoring and configuration functions by which the administrator can manage the fabric and its switches. The CLI is available over an Ethernet connection or a serial connection. Refer to

Appendix B Command Line Interface for more information.

2.7.4

SANsurfer Switch Manager Application Programming Interface

The SANsurfer Switch Manager API enables an application provider to build a management application for QLogic switches. The library is implemented in ANSI standard C, relying only on standard POSIX run-time libraries (except for the Windows NT build). Contact your distributor or authorized reseller for information about the SANsurfer Switch Manager API.

2.7.5

Simple Network Management Protocol

SNMP provides monitoring and trap functions for the fabric. SANbox2 firmware supports SNMP versions 1 and 2, the Fibre Alliance Management Information Base (FA-MIB) version 4.0, and the Fabric Element Management Information Base (FE-MIB) RFC 2837. Traps can be formatted using SNMP version 1 or 2. Refer to the SANbox/SANbox2 Simple Network Management Protocol Reference Guide for more information about using SNMP.

Planning

Consider the following when planning a fabric:

Devices

Device access

Performance

Multiple chassis fabrics

Fabric security

Fabric management

3.1

Devices

When planning a fabric, consider the number of devices and the anticipated demand. This will determine the number of ports that are needed and the number of switches. Consider how many and what types of switches are needed.

The switch uses SFP optical transceivers, but the device host bus adapters you are using may not. Consider whether the device adapters use SFP transceivers or Gigabit Interface Converters (GBIC), and choose fiber optic cables accordingly. Use LC-type cable connectors for SFP transceivers and SC-type cable connectors for GBIC transceivers.

SANbox2 switches support public initiator and target devices. Consider the distribution of target and initiator devices. An F_Port supports a single public device. An FL_Port can support up to 126 public devices in an arbitrated loop.

Device Access

3.2

Device Access

Consider device access needs within the fabric. Access is controlled by the use of zones and zone sets. Some zoning strategies include the following:

Group devices by operating systems.

Separate devices that have no need to communicate with other devices in the fabric or have classified data.

Separate devices into department, administrative, or other functional group.

Reserve a path and its bandwidth from one port to another.

A zone is a named group of devices that can communicate with each other. Membership in a zone can be defined by switch domain ID and port number, port Fibre Channel address, or by device worldwide name (WWN). Devices can communicate only with devices that are within the same zone. A zone can be a member of more than one zone set. Several zone sets can be defined for a fabric, but only one zone set can be active at one time. The active zone set determines the current fabric zoning.

A zoning database is maintained on each switch consisting of all inactive zone sets, the active zone set, all zones, aliases, and their membership. Table 3-1 describes the zoning database limits, excluding the active zone set. Refer to the

SANbox2-8c/16 Switch Management User’s Guide for more information about zoning.

Table 3-1. Zoning Database Limits
Limit	Description
MaxZoneSets	Maximum number of zone sets (256).
MaxZones	Maximum number of zones (1000).

	Device Access

3.2.1

Soft Zones

Soft zoning divides the fabric for purposes of controlling device discovery. Devices in the same soft zone automatically discover and communicate freely with all other members of the same zone. The soft zone boundary is not secure; traffic across soft zones can occur if addressed correctly. The following rules apply to soft zones:

Soft zones that include members from multiple switches need not include the ports of the inter-switch links.

Soft zone boundaries yield to ACL zone boundaries.

Soft zones can overlap; that is, a port can be a member of more than one soft zone.

Membership can be defined by Fibre Channel address, domain ID and port number, or worldwide name.

Soft zoning supports FL_Ports and F_Ports.

3.2.2

Access Control List Hard Zones

Access Control List (ACL) zoning divides the fabric for purposes of controlling discovery and inbound traffic. ACL zoning is a type of hard zoning that is hardware enforced. This type of zoning is useful for controlling access to certain devices without totally isolating them from the fabric. Members can communicate with each other and transmit outside the ACL zone, but cannot receive inbound traffic from outside the zone. The following rules apply to ACL zones:

The ACL zone boundary is secure against inbound traffic.

ACL zones can overlap; that is, a port can be a member of more than one ACL zone.

ACL zones that include members from multiple switches need not include the ports of the inter-switch links.

ACL zone boundaries supersede soft zone boundaries.

Membership can be defined only by domain ID and port ID. A switch port can be a member of multiple ACL zones whose combined membership does not exceed 128.

Performance

3.3

Performance

The SANbox2-16 switch supports class 2 and class 3 Fibre Channel service at transmission rates of 1-Gbps or 2-Gbps with a maximum frame size of 2148 bytes. A port can transmit or receive at 1-Gbps or 2-Gbps depending on the device to which it is connected. The port discovers the transmission speed prior to login when the connected device powers up. Related performance characteristics include the following:

Distance

Bandwidth

Latency

3.3.1

Distance

Consider the physical distribution of devices and switches in the fabric. Choose SFP transceivers that are compatible with the cable type, distance, Fibre Channel revision level, and the device host bus adapter. Refer to

Appendix A Specifications for more information about cable types and SFP transceivers.

Each port is supported by a data buffer with a 12 credit capacity; that is, 12 maximum sized frames. For fibre optic cables, this enables full bandwidth over a distance of 20 kilometers at 1-Gbps (0.6 credits/Km), or 10 kilometers at 2-Gbps (1.2 credits/Km). Beyond this distance, however, there is some loss of efficiency because the transmitting port must wait for an acknowledgement before sending the next frame.

Longer distances can be spanned at full bandwidth by extending credits on G_Ports and F_Ports. Each port can donate 11 credits to a pool from which a recipient port can borrow. For example, you can configure a recipient port to borrow up to 66 credits from 6 ports for a total of 78 credits. This will support communication over approximately 130 Km at 1 Gbps (78÷0.6) or 65 Km at 2 Gbps (78÷1.2).

You can configure recipient and donor ports using SANsurfer Switch Manager or the Set Config command. Refer to ”Set Config Command” on page B-33 for more information.

3.3.2

Bandwidth

Bandwidth is a measure of the volume of data that can be transmitted at a given transmission rate. A port can transmit or receive at 1-Gbps or 2-Gbps depending on the device to which it is connected. The switch supports all transmission rate combinations as shown in Table 3-2.

Table 3-2. Port-to-Port Transmission Combinations

Source Port Rate	Destination Port Rate	Maximum Bandwdith
1-Gbps	1-Gbps	100 MB
1-Gbps	2-Gbps	100 MB
1-Gbps x 2 ports	2-Gbps	200	MB
2-Gbps	1-Gbps x 2 ports	100	MB each port1
2-Gbps	2-Gbps	200 MB

1Bandwidth will be less for larger sequence sizes.

In multiple chassis fabrics, each link between chassis contributes 100 or 200 megabytes of bandwidth between those chassis. When additional bandwidth is needed between devices, increase the number of links between the connecting switches. The switch guarantees in-order-delivery with any number of links between chassis.

3.3.3

Latency

Latency is a measure of how fast a frame travels from one port to another. The factors that affect latency include transmission rate and the source/destination port relationship as shown in Table 3-3.

Table 3-3. Port-to-Port Latency

Source/Destination Rates	Same Switch I
1-Gbps – 1-Gbps	< 1 µsec
2-Gbps – 2-Gbps	< 0.4 µsec

Multiple Chassis Fabrics

3.4

Multiple Chassis Fabrics

By connecting switches together you can expand the number of available ports for devices. Each switch in the fabric is identified by a unique domain ID, and the fabric will automatically resolve domain ID conflicts. Because the Fibre Channel ports are self-configuring, you can connect SANbox2-16 and other FC-SW-2 compliant switches together in a wide variety of topologies.

3.4.1

Optimizing Device Performance

When choosing a topology for a multiple chassis fabric, you should also consider the locality of your server and storage devices and the performance requirements of your application. Storage applications such as video distribution, medical record storage/retrieval or real-time data acquisition can have specific latency or bandwidth requirements. Refer to ”Performance” on page 3-4 for information about latency and bandwidth. However, the highest performance is achieved on Fibre Channel switches by keeping traffic within a single switch instead of relying on ISLs. Therefore, for optimal device performance place devices on the same switch under the following conditions:

Heavy I/O traffic between specific server and storage devices.

Distinct speed mismatch between devices such as the following:

A 2-Gbps server and a slower 1-Gbps storage device

A high performance server and slow tape storage device

3.4.2

Domain ID, Principal Priority, and Domain ID Lock

The following switch configuration settings affect multiple chassis fabrics:

Domain ID

Principal priority

Domain ID lock

The domain ID is a unique number from 1–239 that identifies each switch in a fabric. The principal priority is a number (1–255) that determines the principal switch which manages domain ID assignments for the fabric. The switch with the highest principal priority (1 is high, 255 is low) becomes the principal switch. If the principal priority is the same for all switches in a fabric, the switch with the lowest WWN becomes the principal switch.

The domain ID lock allows (False) or prevents (True) the reassignment of the domain ID on that switch. Switches come from the factory with the domain ID set to 1, the domain ID lock set to False, and the principal priority set to 254. Refer to the SANbox2-8c/16 Switch Management User’s Guide for information about changing the domain ID and domain ID lock using SANsurfer Switch Manager. Refer to the ”Set Config Command” on page B-33 for information about changing the default domain ID, domain ID lock, and principal priority parameters.

An unresolved domain ID conflict means that the switch with the higher WWN will isolate as a separate fabric, and the Logged-In LEDs on both switches will flash green to show the affected ports. If you connect a new switch to an existing fabric with its domain ID unlocked, and a domain ID conflict occurs, the new switch will isolate as a separate fabric. However, you can remedy this by resetting the new switch or taking it offline then back online. The principal switch will reassign the domain ID and the switch will join the fabric.

Note: Domain ID reassignment is not reflected in zoning that is defined by domain ID/port number pair or Fibre Channel address. You must reconfigure zones that are affected by domain ID reassignment. To prevent zoning definitions from becoming invalid under these conditions, lock the domain IDs using SANsurfer Switch Manager or the Set Config Switch command.

Multiple Chassis Fabrics

3.4.3

Common Topologies

The SANbox2-16 switch supports three commonly used fabric topologies:

Cascade

Mesh

Multistage®

3.4.3.1

Cascade Topology

A cascade topology describes a fabric in which the switches are connected in series. If you connect the last switch back to the first switch, you create a cascade-with-a-loop topology as shown in Figure 3-1. The loop reduces latency because any switch can route traffic in the shortest direction to any switch in the loop. The loop also provides failover should a switch fail.

The cascade fabric shown in Figure 3-1 has the following characteristics:

Each chassis link contributes up to 200 MB/s of bandwidth between chassis, 400 MB/s in full duplex. However, because of the sequential structure, that bandwidth will be shared by traffic between devices on other chassis.

Latency between any two ports is no more than two chassis hops.

48 Fibre Channel ports are available for devices.

Mesh Topology

A mesh topology describes a fabric in which each chassis has at least one port directly connected to each other chassis in the fabric. The example mesh fabric shown in Figure 3-2 has the following characteristics:

Each link contributes up to 200 MB/s of bandwidth between switches, 400 MB/s in full duplex. Because of multiple parallel paths, there is less competition for this bandwidth than with a cascade or a Multistage topology.

Latency between any two device ports is one chassis hop.

40 Fibre Channel ports are available for devices.

Multistage Topology

A Multistage topology describes a fabric in which two or more edge switches connect to one or more core switches. Each additional core switch increases the bandwidth to each edge switch by 200 MB/s. The Multistage fabric shown in Figure 3-3 has the following characteristics:

Each link contributes up to 200 MB/s of bandwidth between chassis. Competition for this bandwidth is less than that of a cascade topology, but greater than that of the mesh topology.

Latency between any two device ports is no more than two chassis hops.

	Fabric Security

3.5

Fabric Security

Fabric security consists of the following:

User account security

Fabric services

3.5.1

User Account Security

User account security consists of the administration of account names, passwords, expiration date, and authority level. If an account has Admin authority, all management tasks can be performed by that account in both SANsurfer Switch Manager and the Command Line Interface. Otherwise only monitoring tasks are available. The default account name, Admin, is the only account that can administer user accounts. Consider your management needs and determine the number of user accounts, their authority needs, and expiration dates.

Account names and passwords are always required when connecting to a switch through Telnet. However, SANsurfer Switch Manager does not authenticate account names when opening a fabric unless user authentication is enabled. User authentication is disabled by default and can be changed using the Set Setup System command. Refer to the ”Set Setup Command” on page B-49 for more information. User authentication must be configured the same for all switches in the fabric. If user authentication is disabled, SANsurfer Switch Manager ignores the account name and password entries and logs you in with the default account name and password (admin, password). Consider your user accounts and determine whether user authentication is necessary.

3.5.2

Fabric Services

Fabric services include security-related functions such as inband management and SNMP. Inband management is the ability to manage switches across inter-switch links using SANsurfer Switch Manager, SNMP, management server, or the application programming interface. The switch comes from the factory with inband management enabled. If you disable inband management on a particular switch, you can no longer communicate with that switch by means other than a direct Ethernet or serial connection.

59021-09 A

Fabric Management

You can also enable or disable the Simple Network Management Protocol (SNMP). SNMP is the protocol governing network management and monitoring of network devices. SNMP security consists of a read community string and a write community string, that are the passwords that control read and write access to the switch. The read community string ("public") and write community string ("private") are set at the factory to these well-known defaults and should be changed if SNMP is enabled. If SNMP is enabled (default) and the read and write community strings have not been changed from their defaults, you risk unwanted access to the switch. SNMP is enabled by default. Consider how you want to manage the fabric and what switches you do not want managed or monitored through other switches.

3.6

Fabric Management

The SANsurfer Switch Manager application and CLI execute on a management workstation that provides for the configuration, control, and maintenance of multiple fabrics. Supported platforms include Windows, Solaris, and Linux. The application can be installed and executed on the workstation, or you can run the SANsurfer Switch Manager web applet that is resident on the switch.

Consider how many fabrics will be managed, how many management workstations are needed, and whether the fabrics will be managed with the CLI, SANsurfer Switch Manager, or the SANsurfer Switch Manager web applet.

A switch supports a combined maximum of 19 logins reserved as follows:

4 logins or sessions for internal applications such as management server and SNMP

9 high priority Telnet sessions

6 logins or sessions for SANsurfer Switch Manager inband and out-of-band logins, Application Programming Interface (API) inband and out-of-band logins, and Telnet logins. Additional logins will be refused.
