CPU subsystem
The 3534 Model F08 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: dynamic random
access memory (DRAM), Flash File, and Boot Flash. On the Fibre Channel section
of the system board, the following three components provide high-speed data
transfer:
v The Bloom ASICs
v The Serializer/Deserializer (SERDES)
v The SFP media. SFP media interfaces support SWL and LWL.
An Intel 80960VH CPU is used for management functions and switch initialization.
The CPU runs the Fabric OS and is responsible for switch initialization,
configuration, and management. Switching functionality is provided by the ASIC.
The following peripherals are also supported:
v An Ethernet port
v A serial port
v Three digital thermometers
v A real-time clock
v General input/output (I/O)
The CPU subsystem is a mixed voltage system that uses 1.8 V, 2.5 V, 3.3 V, and 5
V, depending on the device. The maximum board power consumption is 50 W.
Features
The 3534 Model F08 CPU subsystem includes the following features:
v A 80960VH-100 MHz CPU
v An SDRAM controller with parity check at 33 MHz
v A peripheral control interconnect (PCI) bus arbiter
v Main memory (SDRAM): 32 MB
v Flash memory: Dual 8 MB
v Boot flash memory: 512 bytes of 8-bit for system start
v 10BASE-T or 100BASE-T port for management connection with RJ45 connector
v One RS232 port with DB9 connector
Chapter 1. Introduction 3
v Eight light-emitting diodes (LEDs) to indicate the status for each port
v Eight LEDs to indicate the link speed for each port
v One LED on the front panel to indicate the overall switch status
v One LED on the back panel to indicate the overall switch status
v Two LEDs for the Ethernet port to indicate the port status and link speed

v One 3.3 V to 1.8 V dc/dc converter for the Bloom ASIC core supply
v One Bloom ASIC to support up to eight nonblocking ports
v Eight SERDES
v One real-time clock with a battery
Embedded processor
The embedded processor is an Intel 80960VH processor with a clock speed of 100
MHz. It contains the following components:
v A high-performance RISC processor core (compatible with the 2109 and 3534
series of switches)
v An integrated EDO memory controller (for DRAM, SRAM, read-only memory
(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 LEDs, the three digital 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 ASIC, 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
4 IBM TotalStorage SAN Switch: 3534 Model F08 Installation and User’s Guide
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.
The Bloom ASIC is an eight-port Fibre Channel switch controller. A proprietary
10-bit wide SSTL2 bus running at 106.25 MHz is used between the Bloom ASIC
and the SERDES.
Memory and memory architecture
The system design uses three types of memory devices:
v DRAM
v Flash File
v Boot Flash
One on-board SDRAM chips provides up to 32 MB for system memory. One
additional SDRAM chip provides 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.
As with the 2019 series of switches and the 3534 1RU switch, the 3534 Model F08
is based on a central memory architecture. In this scheme, 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 has removed an entry for a frame from its internal
transmit queue in preparation for transmitting a frame, the destination port sends a
transmission complete message (a Finish message) to the port that received the
frame. This allows the receiving port to reuse the buffer for subsequent frames
received.
Central memory is also incorporated into the ASIC. Frames received on the ports in
an ASIC are written into the portion of central memory.
The ASIC contains a RAM device 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
Chapter 1. Introduction 5
transferred in a single operation. Additionally, because there are two buffers
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.
ASIC
The ASIC provides eight Fibre Channel ports that you can use to connect to
external node ports (N_ports) (as an F_port) or external loop devices (as an
FL_port). You can connect one port (as an E_port) to another 3534 or 2109 series
switch. With the fabric upgrade, you might have up to eight E_ports.
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 ASIC is a PCI slave to the CPU. The ASIC interfaces through an
inter-chip 10-bit SSLT2 bus connection clocked at 106.25 MHz. An 8-channel
SERDES is used to support eight 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. 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 with external devices and enables support for shortwave
laser and longwave laser. Two LEDs for each port provide port status and link
speed information.
Ports
Control Message Interface: The 3534 Model F08 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
frame transmission has been completed. A recipient port is free to reuse a receive
buffer when it receives notification that the frame has been transmitted. In the case
of multicast, multiple notifications are required to determine when a receive buffer is
freed.
The CMI interface for the ASIC is connected inside the ASIC. 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 3534 Model F08 supports the following port types:
v Optical ports
v Ethernet port
v Serial port
The ASIC in the 3534 Model F08 connects up to eight SFP modules. SFP devices
are encased in metal to ensure low emissions and high thermal management. They
are hot-swabble and use industry-standard local channel connectors. Each port
6 IBM TotalStorage SAN Switch: 3534 Model F08 Installation and User’s Guide
provides ISL, loop, and fabric (E, F, and FL respectively) type connectivity that the
3534 Model F08 senses automatically. No adminsitration is necessary to identify the
port type.
Optical ports
For optical ports, the 3534 Model F08 uses SFP fiber-optic transceivers that convert
electrical signals to optical signals (and optical signals to electrical signals). Capable
of transmitting at both 1 and 2 Gbps speeds, each SFP fiber-optic transceiver
supports 850 nm SWL on multimode fiber-optic cable or 1310 nm LWL on
single-mode fiber-optic cable. These miniature optical transceivers provide high port
density and deliver twice the port density of standard removable gigabit interface
converter (GBIC) transceivers.
Ethernet port
The 3534 Model F08 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. There are two LEDs for the port. One LED
indicates transmit and receive activity and one LED indicates speed (10 Mbps or
100 Mbps). You can configure the Transmission Control Protocol/Internet Protocol
(TCP/IP) address for the port from the serial port.
Serial port
An RS232 serial port is provided on the 3534 Model F08. The serial port uses a
DB9 connector. The connector is a header pin block on the system board. The
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.
Enclosure
You 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. The
serial port connection should not be used 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 you to set a specific switch IP address.
The 3534 Model F08 enclosure is designed for you to mount it in a 19-in. rack, with
a height of 1 RETMA unit, but you can use it in a tabletop configuration.
The 3534 Model F08 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 is hot-swappable so that it can be removed
and replaced without interrupting the system power.
Other than the SFP replacement, the 3534 Model F08 has no user-serviceable
parts.
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, ac power input cables, and serial port
cables are located on the front of the switch.

LEDs
The 3534 Model F08 provides several LEDs to indicate status on the switch. Each
of the eight ports has two status indicators. The first LED for the port is a two-color
(green and yellow) LED, and indicates the status for the port. Green indicates
normal status, and yellow indicates an error. The second LED is a single-color
(green) LED and indicates the link speed for the port. Green indicates 2 Gbps. If
the green LED is not lit (dark), it indicates 1 Gbps.
A single-color (green) LED is located on the front of the switch and indicates system
power-on status. On the back of the switch, there is a two-color (green and yellow)
LED driven by an I2C I/O expander that indicates the mode of the unit. Green
indicates normal mode, and yellow indicates diagnostic mode. All LEDs are surface
mount components with on-board light pipe and are visible externally with full
chassis enclosure.
There are two LEDs for the Ethernet port located on the front panel. One LED
indicates the transmit and receive activity, and one LED indicates speed (10 Mbps
or 100 Mbps).
