Product overview

Figure 3 shows the 2109 Model F16.

SJ000309

Figure 3. 2109 Model F16

The 2109 Model F16 is a 16-port, dual speed, auto-sensing Fibre Channel switch. It delivers the next generation of performance and functionality for Storage Area Networks (SANs). As the first product in the new 2109 Model F16 series, the 2109 Model F16 is functionally compatible and interoperable with the current 2109 series of switches and the 3534 switch. The 2109 Model F16 is an enterprise class switch that is designed to handle the large scale SAN requirements of an enterprise. You can also use it to address the SAN requirements of a small to medium-sized workgroup. Providing 16 ANSI Fibre Channel compliant ports (E_ports, FL_ports, and F_ports), the 2109 Model F16 is a flexible switching platform that meets both low-latency and high-throughput demands. Based on Application Specific Integrated Circuit (ASIC) technology (called the Bloom), the 2109 Model F16 provides high levels of reliability, availability, and port density. The 2109 Model F16 provides Fibre Channel throughput at twice the previous speeds. It also has new features that enhance the manageability and performance of the switch.

The 2109 Model F16 switch provides the following features:

v 16 nonblocking ports that provide full-duplex, throughput bandwidth at either

1.0625 Gbps or 2.125 Gbps

v Fibre Channel auto-sensing ports that self-negotiate to the highest speed that is

supported by the attached devices

v Universal ports that self-configure as fabric ports (F_ports), fabric loop ports

(FL_ports), or expansion ports (E_ports)

v Trunking, which allows you to group up to four ports to create high-performance

8 Gbps inter-switch link (ISLs) between switches

v Hardware zoning that permits or denies delivery of frames to any particular

destination port address

v Frame filtering, which augments the hardware zoning capabilities of the

second-generation ASIC. The second-generation ASIC implements hardware zoning at the port level of the switch. The expanded capabilities of the third-generation ASICs include world wide name (WWN), device-level zoning, protocol-level zoning, and logical unit number (LUN)-level zoning to provide the flexibility of second generation software zoning with the enhanced security of hardware zoning.

Note: You will need Fabric OS version 3.1 for protocol-level and LUN-level

zoning support.

v Phantom loop addressing that allows private 8-bit loop addresses to be treated

as equivalent to public loop addresses

v Support for unicast, multicast (up to 256 groups), and broadcast data traffic types

v Extensive diagnostics, system-monitoring capabilities, and dual redundant,

hot-swappable power supplies and cooling units that provide high reliability, availability, and serviceability

v A single system board design with a 100 MHz 80960VH reduced instruction-set

computer (RISC) central processing unit (CPU) with integrated peripherals that provide high performance

v Small form-factor pluggable (SFP) media that supports short wavelength (SWL)

optical, and long wavelength (LWL) optical

v Fabric Operating System (OS) that delivers distributed intelligence throughout the

network and enables a wide range of applications

v A flexible topology that allows the interconnection of up to 239 switches to create

a medium to large Fibre Channel fabric. The topology can change dynamically as you add new switches or links to the fabric or as your needs change.

v Central memory architecture that maximizes switch throughput, guarantees full

transmit and receive bandwidth to all Fibre Channel ports at all times, and enables a number of sophisticated queuing, messaging, and buffer pool management schemes to optimize switch performance characteristics in heavily loaded systems

v Cut-through frame routing that minimizes port-to-port latency

Hardware components

The 2109 Model F16 system board is a single-board design with a highly integrated CPU. The Intel®80960VH CPU is a RISC core processor and is the top choice for this platform. It provides over 70% of the functionality for the digital section of the system board. The system uses three types of memory devices: DRAM, Flash File, and Boot Flash. On the Fibre Channel section of the system board, the Bloom

2 IBM TotalStorage SAN Switch: 2109 Model F16 User’s Guide

CPU subsystem

ASICs, the Serializer/Deserializer (SERDES), and the SFP media are the key components that provide high-speed data transfer. SFP media interfaces support SWL and LWL.

The system chassis is a 1U height enclosure with space for two power supply units and one system board. The system board is placed in an Electromagnetic Interference (EMI) enclosure tray as an EMI-proof system unit. Two 126-watt removable, redundant power supplies provide hot-swappable capability. Cooling fans are mounted in the rear to provide airflow for system cooling.

An Intel 80960VH CPU is used for switch initialization and management functions. The CPU runs the Fabric OS and is responsible for switch initialization, configuration, and management. IBM-designed ASICs provide the switching functionality.

The following peripherals are also supported:

Figure 4. Simplified 2109 Model F16 CPU subsystem block diagram

Embedded processor

The embedded processor is an Intel 80960VH processor with a clock speed of 100 MHz. It contains the following features:

v A high-performance RISC processor core (compatible with the 2109 series of

switches and the 3534 switch)

v An integrated EDO memory controller (for DRAM, SRAM, ROM, and Flash

memory)

v A PCI bus interface

v A complex programmable logic device (CPLD) for SDRAM control

v Two direct memory access (DMA) channels

v An I2C interface

v General purpose I/O

You access system memory through the local bus. The external CPLD SDRAM device provides SDRAM controller functionality at 33 MHz. It supports parity checking to enhance the data integrity of the system. The CPU communicates with the ASIC and the 10BASE-T or 100BASE-T Ethernet media access controller (MAC) through the PCI interface. An external PCI bus arbiter enables the Ethernet device to be a bus master.

You can also access the RS232 Universal Asynchronous Receiver Transmitter (UART) serial port through the local bus. Other I/O peripherals, such as the real-time clock, the two power supply controls, the LEDs, the three digital

4 IBM TotalStorage SAN Switch: 2109 Model F16 User’s Guide

thermometers, and miscellaneous I/O are handled by the I2C bus of the CPU. The CPU is the only I2C bus master in the system. The RS232 port and drivers, Ethernet MAC/PHY, and LEDs are external components to the CPU. An RJ45 connector provides Ethernet connection to external systems. The DB9 RS232 is a ribbon-cable connection through the on-board 10-pin header.

Bus operations

The interface between the embedded processor, the ASICs, and the 10BASE-T or 100BASE-T Ethernet MAC is implemented by using a PCI bus. All PCI devices on the bus are PCI Revision 2.2 compliant. The PCI bus interface operates at 32-bit, up to 33 MHz and has a worldwide even parity bit. A slave-only PCI interface is provided by each ASIC to allow the processor to program various registers, routing tables, and so on within the chip. An external PCI bus arbiter enables the Ethernet device to be a bus master.

The local bus, a 32-bit multiplexed burst bus, provides the interface between the system memory and the I/O. Because the integrated EDO memory controller on the CPU allows only direct control for DRAM, SRAM, ROM, and Flash memory, the external CPLD controller is included to provide SDRAM controller functionality.

The I2C bus provides peripheral I/O control for the LEDs, the thermometers, and general I/O functions. The 80960VH CPU serves as the master on the I2C bus.

Each Bloom ASIC is an eight-port Fibre Channel switch controller. There are two Bloom ASICs to support up to 16 ports. The communication between ASICs is over a proprietary 10-bit wide SSTL2 bus running at 106.25 MHz. An SSTL2 bus is also used between the Bloom ASICs and the SERDES.

Memory

The system design uses three types of memory devices:

v DRAM

v Flash File

v Boot Flash

Two on-board SDRAM chips provide up to 16 MB for system memory. Two additional SDRAM chips provide data parity. The printed circuit board (PCB) SDRAM footprint is designed to be compatible with 64 MB, 128 MB, and 256 MB devices. An external CPLD device added to the local bus provides control functions for the 80960VH processor.

The system provides 4 MB of on-board redundant Flash File memory for software and data storage. The Boot Flash is an 8-bit Flash device socket that is used only for system start. The Boot Flash device contains a block area for startup code protection. The PLCC32 socket supports 3.3 V Boot Flash memory up to 512 KB.

Central memory: As with the 2019 series of switches and the 3534 switch, the 2109 Model F16 is based on a central memory architecture. In this architecture, a set of buffers in the central memory is assigned to each port to be used for receipt of frames. As an ASIC port receives and validates a frame, it stores the frame in one of its receive buffers in the central memory and forwards a routing request (a Put message) to the appropriate destination ports. When a destination port is capable of transmitting the frame, it reads the frame contents from central memory and forwards the frame to its transmit interface. It does not wait for the frame to be written in memory, unless the port is busy. After it removes an entry for a frame from its internal transmit queue in preparation for transmitting a frame, the

Chapter 1. Introduction 5

destination port sends a transmission complete message (a Finish message) to the port that received the frame. This method allows the receiving port to reuse the buffer for subsequent frames received.

The central memory is also incorporated into the ASICs. Frames received on the ports in an ASIC are written into the portion of central memory in the receiving chip. Received frames cannot be written into the sections of central memory located in other ASICs. All transmitters in a 2109 Model F16 switch can read from the memories in any of the ASICs, through inter-chip connections clocked at 106.25 MHz.

Each ASIC contains RAM devices plus data path crossbar logic that is used to implement the central memory. Memory blocks are accessed in a time-sliced fashion. The buffer pool can be split into 2112-byte buffers or into 312-byte mini-buffers. If frames that need to be buffered are smaller than the maximum 2112 bytes, using mini-buffers effectively expands the buffer pool and increases the efficiency of memory usage by providing more (but smaller) receive buffers.

Additionally, the Bloom ASIC provides a special memory interface (SMI). The SMI provides the firmware with a mechanism to read and write frame contents to and from the ASIC. It also supports higher throughput transfers. The SMI includes a set of two buffers that are large enough for an entire maximum-sized frame to be transferred in a single operation. Additionally, because two buffers are available, the firmware can perform a read or write on a frame in one of the buffers while the ASIC streams another frame into the other buffer.

ASICs

Two ASICs within the system provide the switching functionality. Each ASIC provides eight Fibre Channel ports that you can use to connect to external node ports (N_ports) (as an F_port), external loop devices (as an FL_port), or to other 3534 or 2109 series boxes (as an E_port).

Each port can operate at either 1.0625 Gbps or 2.125 Gbps link speeds. The ASIC contains the Fibre Channel interface logic, message and buffer queuing logic, receive buffer memory for the eight on-chip ports, and other support logic.

The Bloom ASICs are PCI slaves to the CPU. The two ASICs interface through an inter-chip 10-bit SSLT2 bus connection clocked at 106.25 MHz. A 16-channel SERDES is used to support 16 ports. The interface between ASIC and SERDES is also a 10-bit SSTL2 bus running at 106.25 MHz. The SERDES converts the 10-bit wide parallel data from the SSTL2 bus into high-speed serial data for the SFP media and vice versa. The SERDES supports single data rate (SDR) or double data rate (DDR) transfer between the SERDES and the SFP media. The DDR operation supports 2.125 Gbps data transfer rate between ASICs. Implementing the SERDES external to the ASIC reduces the risk of silicon packaging as well as the risk of running 2.125 Gbps signals on a board with a long trace length.

The SFP media interfaces to external devices and enables support for shortwave laser and longwave laser. Two LEDs for each port provide port status and link speed information.

Control Message Interface: The 2109 Model F16 Control Message Interface (CMI) consists of a set of control signals that are used to pass hardware-level messages between ports. Recipient ports use these control signals to inform transmitting ports when a new frame needs to be added to the output queue of the transmitter. Transmitting ports also use the CMI to inform recipient ports that a

6 IBM TotalStorage SAN Switch: 2109 Model F16 User’s Guide

Ports

frame transmission has completed. A recipient port is free to reuse a receive buffer when it receives notification that the frame was transmitted. In the case of multicast, multiple notifications are required to determine when a receive buffer is freed.

The CMI interfaces for the ASICs are connected inside each ASIC through a message crossbar, implementing a barrel shift message scheme. Each chip time slices its output port to each possible destination chip in the switch. If it has a message to send to a particular destination during the corresponding time slot, the chip uses the time slot to send the message. Otherwise, the output port lines are driven to indicate that no message is present.

The time slicing of the output CMI control signals of the ASICs are arranged out of phase from each other so that each chip’s output port is time sliced to a different destination chip in any given clock cycle. Messages that display at the input control signal interface of a given ASIC are also time sliced through each possible source chip in the switch.

The 2109 Model F16 supports the following port types:

v Optical ports

v Ethernet port

v Serial port

Each ASIC in the 2109 Model F16 switch connects up to eight SFP media. SFP devices are encased in metal to ensure low emissions and high thermal management. They are hot-swappable and use industry-standard local channel connectors. Each port provides ISL, loop, and fabric (E, F, and FL respectively) type connectivity that the 2109 Model F16 senses automatically. It requires no administration to identify the port type.

Optical ports

For optical ports, the 2109 Model F16 uses SFP fiber-optic transceivers that convert electrical signals to optical signals (and optical signals to electrical signals).

Each SFP fiber-optic transceiver is capable of transmitting at both 1 and 2 Gbps speeds and supports:

v 850 nm SWL on multimode fiber-optic cable

v 1310 nm LWL on single-mode fiber-optic cable

v 1550 nm ELWL 5 on single-mode fiber-optic cable

These miniature optical transceivers provide high port density and deliver twice the port density of standard removable GBIC transceivers.

Ethernet port

The 2109 Model F16 provides a fully IEEE-compliant 10BASE-T or 100BASE-T Ethernet port for switch management console interface. When a device is connected to the port, both ends negotiate to determine the optimal speed. The Ethernet port uses an RJ45 connector. Two LEDs are for the port. One LED indicates transmit and receive activity and the other LED indicates speed (10 Mbps or 100 Mbps). You can configure the TCP/IP address for the port from the serial port.

Serial port

The 2109 Model F16 provides an RS232 serial port. The serial port uses a DB9 connector. The connector is a header pin block on the system board. The

Chapter 1. Introduction 7

Enclosure

parameters of the serial port are fixed at 9600 baud, 8 data bits, no parity, no hardware flow control, 1 start and 1 stop bit.

Use this connector to configure the Internet protocol (IP) address and to recover the factory default settings of the switch should Flash memory contents be lost. You should not use the serial port connection to perform normal administration or maintenance functions. Accessible functions are limited to connecting a terminal to the port to reinitialize the switch defaults, which restores the switch to its factory configuration. This is required to restore the switch passwords to a known state and to allow customers to set a specific switch IP address.

The 2109 Model F16 enclosure is designed so that you can mount it in a 19-inch rack, with a height of 1 RETMA unit (1µ). But you can also use it in a tabletop configuration. The enclosure houses dual-redundant power supplies, dual-redundant fan assemblies, and a system board that supports the two ASICs and the CPU.

The 2109 Model F16 enclosure has forced-air cooling. The fans push the air from the rear chassis intake through the enclosure and exhaust the air through venting holes in the front panel. The SFP media, the cooling fan, and the power supplies are hot-swappable so that they can be removed and replaced without interrupting the system power.

The top panel of the 2109 Model F16 enclosure can be removed without tools, allowing access to the system board. The enclosure design provides for simple assembly of the system board into the enclosure, allowing for ease of manufacture and maintenance. All pieces of the product are modular. You can perform all maintenance without special tools.

Power supply

On the front of the unit, there are two port connections (an RS232 connection and an RJ45 connection). The RJ45 connection provides a 10BASE-T or 100BASE-T Ethernet port for a full system management console interface. The RS232 connection provides a serial port interface for setting the IP address of the switch and for resetting the switch to factory defaults.

The fibre-optic cables, Ethernet cables, and serial port cables are located on the front of the switch. AC power input cables, power supplies, and cooling modules are inserted and removed from the rear of the switch.

The 2109 Model F16 power supply is a hot-swappable switching unit, allowing 1+1 redundant configurations. The unit is a universal power supply capable of functioning worldwide without voltage jumpers or switches. The fully enclosed, self-contained unit has its own internal fans to provide cooling. It is auto-ranging in terms of accommodating input voltages. The power supply has three dc outputs (3.3 V, 5 V, and 12 V) that provide a total output power of 126 maximum usable watts. The power supplies plug directly into the enclosure from the rear of the unit, mating to internal blind connectors that connect both the dc outputs and the interface signals to the system backplane. The power supply provides an integral on/off switch, input filter, and power indicator.

v Command-line interface (CLI) through a Telnet connection

v Advanced Web Tools

v SCSI Enclosure Services (SES)

v SNMP applications

You can use all these management methods either in-band (Fibre Channel) or out-of-band (Ethernet), except for SES, which can be used for in-band only.

For more information about these management interfaces, see the Brocade Fabric OS Procedures Guide.

Diagnostics

The 2109 Model F16 switch supports a set of power-on self tests (POSTs), as well as tests that you can invoke by using Telnet commands. These diagnostics are used during the manufacturing process as well as for fault isolation of the product in your installation.

Diagnostic environment

Most diagnostics are written to run in the VxWorks environment. However, as VxWorks does not run without a working SDRAM, a SDRAM/boot EEPROM test is run as part of the pre-VxWorks startup code to verify that the basic processor-connected memories are functioning properly.

12 IBM TotalStorage SAN Switch: 2109 Model F16 User’s Guide

Hardware support

Loop-back paths for frame traffic are provided in the hardware for diagnostic purposes. You can use a loop-back path within the ASIC, at the final stages of the Fibre Channel interface, to verify that the internal Fibre Channel port logic is functioning properly, as well as paths between the interface and the central memory. Additionally, the SerialLink macro within the ASIC includes a serial data loop-back function that can be enabled through a register in the corresponding ASIC.

Diagnostics are provided to allow traffic to be circulated between two switch ports that are connected with an external cable. This allows the diagnostics to verify the integrity of the final stage of the SERDES interface, as well as the media interface module.

Diagnostic coverage

The POST and diagnostic commands concentrate on the Fibre Channel ports and verify switch functionality of the 2109 Model F16 switch. For more information, see the Brocade Diagnostic and System Error Message Reference.

v “Turning on and off the 2109 Model F16”

v “Interpreting LED activity”

v “Interpreting POST” on page 19

v “Maintaining the switch” on page 20

To turn on the 2109 Model F16, connect one or both of the power supplies to a power source, then flip the ac power switch to “I”.

To turn off the switch, flip the ac switch for both power supplies to “O”.

Note: When you remove all power from the switch, a system reset is triggered.

When you restore the power, all devices are returned to the initial state, and the switch runs a POST, a one-minute system check.

You can determine system activity and status by monitoring the activity of the LEDs on the switch.

Note: The LEDs might flash green, orange, or yellow during a POST. This is

normal and does not indicate a problem unless the LEDs do not return to a normal pattern after a POST completes.

Each time you power on or reset the switch, the switch automatically performs a POST, a one-minute system check. The LEDs flash during a POST, but all LEDs should return to a normal state when the POST is complete.

To determine whether a POST completed without errors, verify that all LEDs return to a normal state after the POST is complete. If one or more LEDs continue to flash, see “Interpreting LED activity” on page 15. Verify that the flashing is not due to the switch being configured to beacon.

Note: The switchBeacon command sets the switch beaconing mode on or off if

the operand is 1 or 0 respectively. When you turn on beaconing mode, the port LEDs flash orange in a running pattern from port 0 - port 15, port 15 port 0, and then back to port 15 again.

For more information about the switchBeacon command, see the Brocade Fabric OS Reference.

Note: If the switch prompt does not display, or if the Power Supply LED or the

Switch Status LED flashes, the POST did not successfully complete. You should then return the switch for repairs.

If errors are detected during a POST, error messages are written to the system error log. You can view this error log by using the errShow command. For information about error messages, see the Brocade Diagnostic and System Error Message Reference.

Chapter 2. Operating the 2109 Model F16 19

Maintaining the switch

| | | | |

| | | | | |

| | | | |

The 2109 Model F16 does not require any physical maintenance and is designed to minimize the chance of failure. However, if a failure occurs, the you can replace some of the switch components. For more information, see IBM TotalStorage SAN Switch 2109 Model F16 Installation and Service Guide. Diagnostic tests are provided to help troubleshoot the hardware and the firmware.

The diagnostic tests include tests of internal connections and circuitry, fixed media, and any SFP modules and fiber optic cables that are in use. The tests are implemented by commands, either through a Telnet session or through a terminal that is set up for a serial connection to the switch. Some tests require that the ports be connected by external cables, allowing the diagnostics to verify the serializer or deserializer interface, as well as the attached SFP and cable.

All diagnostic tests are run at link speeds of 1 Gbps and 2 Gbps. As a result, the transmit and receive speed of the links can be temporarily locked at one speed or the other while the diagnostic tests are running. For information about the specific diagnostic tests and how to run them, see the Brocade Diagnostic and System Error Message Reference.

v IEEE 802.3 for Ethernet

Protocol compliance

The 2109 Model F16 complies with the following standards and protocols.

Support for Fibre Channel ports

All ports on the 2109 Model F16 are universal ports and support F_port (point-to-point), FL_port (loop), and E_port (switch-to-switch) port connections.

Fibre Channel class operation

The 2109 Model F16 supports Fibre Channel Classes 2, 3, and F operations on all ports.

Auto-configuration

All ports support E_ports to allow for cascading switches to form larger fabrics. E_ports are auto-configuring. Linking ports from any two switches automatically configure an E_port connection to form the fabric. The 2109 Model F16 supports a trunking option that binds up to four ports together as a high-performance trunk group. In this trunking configuration, inter-switch data transfers can occur at an

aggregate rate of 800 MBps in both directions. The trunk group is automatically configured on the ports of the switch as the links between the switches are connected.

In-order delivery

The 2109 Model F16 guarantees in-order delivery of frames between source F/FL and destination F/FL ports. In-order delivery is supported across any arbitrary switch configurations or fabric topologies.

Flexibility of fabric topology and operation

The 2109 Model F16 implements the Fabric Shortest Path First (FSPF) routing protocol as specified in the T11 FC-SW-2 standard. Fabric topology and operation are automatically adjusted and dynamically distributed to the fabric as new switches and links are added to the fabric. This is completed with no operator intervention. When a link is added or removed, the routes are recalculated. The switch adopts a minimal disruption algorithm to minimize the impact of the route recalculation. To minimize disruption, the switch only reroutes traffic due to a new shortest path (if one has been established) or if new load sharing is required.

22 IBM TotalStorage SAN Switch: 2109 Model F16 User’s Guide

Appendix B. Interoperability, reliability, serviceability, and specifications

This appendix provides the following information:

v “Interoperability”

v “Reliability and serviceability”

v “Specifications” on page 24

Interoperability

This section includes information about interoperability.

Switch interoperability

The 2109 Model F16 switch supports both 1 Gbps and 2 Gbps transmit and receive rates with auto-negotiation. The actual data signaling rate that is used on a port is automatically sensed and is set to the rate that is supported by a device or devices that are attached to the port. The 2109 Model F16 has been tested and is compliant with the current Fibre Channel standards. The 2109 Model F16 is compatible with most current-generation switches N_ports, NL_ports, and E_ports, as well as host adapters, Redundant Array of Independent Disks (RAID) storage devices, hubs, and Fibre-SCSI bridge devices, including the 3534 and 2109 series of switches.

Implementation in existing environments

Because the 2109 Model F16 switch has a compatible 1 Gbps auto-negotiated signaling rate on each port, you can use it as a replacement for current 3534 and 2109 series switches. As newer technology is added to existing systems that support 2 Gbps signaling, the ports can accept these devices and interoperate with existing 1 Gbps devices. If the 2109 Model F16 is connected to a third-party device but is unable to negotiate the signaling rate, the 2109 Model F16 allows you to manually set the speed of each port through the management interfaces.

Host bus adapter interoperability

See the following Web site for the host bus adapter supported fibre matrix:

ssddom02.storage.ibm.com/hba/hba_support.pdf

Reliability and serviceability

This section includes information about reliability and serviceability for the 2109 Model F16.

Reliability

The 2109 Model F16 switch provides the following features to ensure reliability:

v POST

v Error detection and fault isolation (internal and external cyclic redundancy check

(CRC) checking, parity checking, checksum, and illegal address checking)

v Continuous monitoring of environmental components (fan status and

temperature)

v DC power in proper range monitoring

v Low component count

Serviceability

Low component count

Because buffering is integrated into the ASICs in the 2109 Model F16, you do not need external SRAM chips on the system board.

The 2109 Model F16 switch uses a highly integrated 80960VH processor that incorporates a memory controller, PCI bus arbiter, and I2C controller in the processor chip, reducing the parts count for the processor functions. Because a single system board contains all circuitry, the 2109 Model F16 requires no interboard connections.

The 2109 Model F16 switch has the following features to enhance serviceability:

v Modular design with hot-swappable components

v Few internal cables or harnesses

v Simple enclosure

v Captive hardware

v Loop-back test mode for manufacturing and service

v Extensive and user-friendly diagnostics

v No jumpers or hardware settings

v Modular field-replaceable units (FRUs)

FRUs

FRUs for the 2109 Model F16 series include:
