CHAPTER
1
System Overview
The Netra 440 server is a high-performance, shared memory, symmetric
multiprocessing server that supports up to four UltraSPARC® IIIi processors. The
UltraSPARC IIIi processor implements the SPARC® V9 Instruction Set Architecture
(ISA) and the Visual Instruction Set extensions (Sun VIS™ software) that accelerate
multimedia, networking, encryption, and Java™ software processing.
System reliability, availability, and serviceability (RAS) are enhanced by features that
include hot-swappable hard drives and redundant, hot-swappable power supplies.
A full list of RAS features is in Chapter 2.

System Configuration Card
The system configuration card (SCC) contains unique network identity information,
including the Ethernet MAC addresses and host ID (stored in idprom), the
OpenBoot firmware configuration (stored in nvram), and ALOM system controller
user and configuration data. It supplants the NVRAM module used on previous Sun
systems. The SCC is housed in a slot in the system controller card reader, behind the
system door (FIGURE 1-10).

FIGURE 1-10
Four-Position Rotary Switch
A new system on the network can inherit an old system’s host ID and Ethernet MAC
addresses through the old system’s SCC. Thus, migrating a SCC from one Netra 440
server to another can smooth the transitions to a new or upgraded system, or
quickly bring up a backup system if a primary system becomes unavailable, without
disrupting the system’s identity on the network.
For instructions on migrating a SCC from one system to another, refer to the Netra
440 Server Service Manual.
14
Netra 440 Server Product Overview • March 2006
System Configuration Card Reader
The system configuration card reader holds the system configuration card (discussed
in “System Configuration Card” on page 14). It also has the On/Standby button and
the rotary switch for the system.
On/Standby Button
The system On/Standby button is recessed to prevent accidentally turning the
system on or off. The ability of the On/Standby button to turn the system on or off
is controlled by the rotary switch. The ALOM system controller can also control the
power-on and power-off functions if environmental conditions are out of
specification or if the ALOM system controller detects that the system configuration
card (SCC) is missing or invalid. See “System Control Rotary Switch” on page 15.
If the operating system is running, pressing and releasing the On/Standby button
initiates a graceful software system shutdown. Pressing and holding in the
On/Standby button for four seconds causes an immediate hardware shutdown.
Caution – When possible, use the graceful shutdown method. Forcing an
immediate hardware shutdown can cause hard drive corruption and loss of data.
System Control Rotary Switch
The four-position rotary switch on the front panel controls the power-on modes of
the system. The rotary switch also prevents unauthorized users from powering off
the system or reprogramming system firmware.
Chapter 1
System Overview
15
The following table describes the function of each rotary switch setting.
TABLE 1-8
Position
Standby
Rotary Switch Settings
Icon
Description
This setting forces the system to power off immediately and to enter standby
mode. It also disables the system On/Standby button. This setting is useful
when AC/DC power is interrupted and you do not want the system to restart
automatically when power is restored. With the rotary switch in any other
position, if the system were running prior to losing power and the power state
memory is enabled in the ALOM system controller, the system restarts
automatically once power is restored.
The Standby setting also prevents anyone from restarting the system during an
ALOM system controller session. However, the ALOM system controller card
continues to operate using the system’s standby power.
Normal
This setting enables the system On/Standby button, allowing you to power the
system on or off. If the operating system is running, pressing and releasing the
On/Standby button initiates a graceful software system shutdown. Pressing and
holding the On/Standby button in for four seconds causes an immediate
hardware power off.
Locked
This setting disables the system On/Standby button to prevent unauthorized
users from powering the system on or off. It also disables the keyboard L1-A
(Stop-A) command, terminal Break key command, and ~# tip window
command, preventing users from suspending system operation to access the
system ok prompt. The Locked setting is recommended for normal day-to-day
operations, and prevents unauthorized programming by write-protecting system
firmware.
The ALOM system controller can still affect the system power state through a
password-secured ALOM session, even when the rotary switch is in the Locked
position. This capability provides remote management of the system.
Diagnostics
16
This setting forces the power-on self-test (POST) and OpenBoot Diagnostics
software to run firmware diagnostic tests at power on or during reset events. The
On/Standby button functions the same as when the rotary switch is in the
Normal position.
Netra 440 Server Product Overview • March 2006
Hard Drives
The Netra 440 server supports up to four internal, hot-swappable Ultra-4 Small
Computer System Interface (SCSI) hard drives, attached to a backplane. Drives are
3.5-inches wide and 1-inch high (8.89-cm x 2.54-cm). The system also includes an
external Ultra-4 SCSI port. See “Ultra-4 SCSI Port” on page 22.
The following figure shows the system’s four internal hard disk drives (HDDs).
Hard disk drives are numbered 0, 1, 2, and 3, with HDD0 being the default system
drive.

FIGURE 1-11
Internal Drive Bay Locations
Internal drives have a storage capacity of up to 73 Gbytes each, with a rotation speed
of 15,000 revolutions per minute. The maximum internal storage capacity is
292 Gbytes (using four 73-Gbyte drives), with larger capacities possible as drive
storage capacities continue to grow.
Chapter 1
System Overview
17
The drives are supported by the 320-Mbyte per second Ultra-4 SCSI interface to the
internal Ultra-4 SCSI controller on the system’s motherboard. The drives connect to
the four-drive Ultra-4 SCSI backplane.
Three LEDs are associated with each drive, indicating the drive’s operating status,
hot-swap readiness, and any fault conditions associated with the drive. See “LED
Status Indicators” on page 4 for a description of these LEDs.
The hot-swap feature of the system’s internal hard drives allows you to add,
remove, or replace drives while the system continues to operate. This capability
significantly reduces system downtime associated with hard drive replacement.
However, certain software preparations are required prior to removing or installing
a drive. To perform hard drive hot-swap operations, you use the Solaris cfgadm
utility. The cfgadm utility is a command-line tool for managing hot-swap operations
on Netra 440 internal hard drives and external storage arrays. For more information
about cfgadm, see the cfgadm man page.
Hard drive hot-swap procedures involve software commands for preparing the
system prior to removing a hard drive and for reconfiguring the operating
environment after installing a drive. For detailed instructions, see the Netra 440
Server Service Manual.
The Solaris Volume Manager software supplied as part of the Solaris OS lets you use
internal hard drives in four software RAID configurations: RAID 0 (striping),
RAID 1 (mirroring), RAID 0+1 (striping plus mirroring) and RAID 5 (striping with
parity). You can also configure drives as hot-spares, drives installed and ready to
operate if other drives fail. In addition, you can configure hardware mirroring using
the system’s Ultra-4 SCSI controller. For more information about all supported RAID
configurations and configuring hardware mirroring, refer to the Netra 440 Server
System Administration Guide.

Netra 440 Server Product Overview • March 2006
Fan Trays
In addition to the power supply fans, the system is equipped with three fan trays
(fan trays 0-2), which are installed between the hard drives to provide front-to-rear
cooling of the hard drives and the system, and another fan tray (fan tray 3) for
cooling hard drives and PCI cards. Each fan tray houses a single fan. All fans and
fan trays must be present and operating to provide adequate cooling.
Fan trays 0-2 are hot-swappable, and are accessible from the front of the system
without having to remove the top cover. Fan tray 3 is cold-swappable, and is
accessible from the top of the server. If fan tray 3 fails, the Netra 440 server will
automatically go through a soft shutdown. Power supplies are cooled separately,
each power supply with its own internal fan.
FIGURE 1-12 shows the fan trays.

The system Service Required LED lights when a fault is detected in fan tray 3. Above
fan trays 0-2, the amber fault LED light when a fault is detected in a fan installed in
a fan tray. The environmental subsystem monitors the fan trays in the system, and
prints a warning and lights the system Service Required LED if a fan in a fan tray
falls below its nominal operating speed. This provides an early warning to an
impending fan failure, allowing you to schedule downtime for replacement before
an overtemperature condition shuts down the system unexpectedly.
In addition, the environmental subsystem prints a warning and lights the system
Service Required LED if internal temperature rises above a predetermined threshold,
either due to fan failure or external environmental conditions. For additional details,
see the Netra 440 Server Diagnostics and Troubleshooting Guide.
Power Distribution Board
The power distribution board takes the DC power from the four power supplies
located at the rear of the system and provides power to the motherboard through
two connectors. The power distribution board is accessible from the front of the
system, behind the front door.

Netra 440 Server Product Overview • March 2006
DVD Drive
Both DVD-ROM drives and DVD-RW drives are supported in the Netra 440 server
(both are referred to as the DVD drive in this document). The DVD drive is not a
hot-swappable component; you must power down the server before you can remove
or install a DVD drive into the system. The DVD drive does not come standard with
the Netra 440 server, so you must order it separately. Refer to the Netra 440 Server
Installation Guide or the Netra 440 Server Service Manual for information on ordering
and installing a DVD drive.
Rear Panel Ports
Ethernet Ports
The system provides two on-board Gigabit Ethernet ports, which support several
modes of operations at 10, 100, and 1000 megabits per second (Mbps). Additional
Ethernet interfaces or connections to other network types can be provided by
installing the appropriate PCI interface cards. Multiple network interfaces can be
combined with Solaris Internet Protocol (IP) network multipathing software to
provide hardware redundancy and failover capability, as well as load balancing on
outbound traffic. Should one of the interfaces fail, the software can automatically
switch all network traffic to an alternate interface to maintain network availability.
For more information about network connections, refer to the Netra 440 Server
Installation Guide.
Serial Ports
The system also provides a standard serial communication port through a DB-9 port
(labeled 10101) located on the back panel. This port corresponds to TTYB, and
supports baud rates of 50, 75, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400, 4800, 9600,
19200, 38400, 57600, 115200, 153600, 230400, 307200, and 460800. The port is
accessible by connecting a serial cable to the back panel serial port connector.
Chapter 1
System Overview
21
USB Ports
The system back panel provides four external Universal Serial Bus (USB) ports on
two independent controllers to connect USB peripheral devices such as:
■
■
■
■
■
■
Sun Type-6 USB keyboard
Sun opto-mechanical three-button USB mouse
Modems
Printers
Scanners
Digital cameras
The USB ports are compliant with the Open Host Controller Interface (Open HCI)
specification for USB Revision 1.0. The ports support isochronous and asynchronous
modes, and enable data transmission at speeds of 1.5 Mbps and 12 Mbps. Note that
the USB data transmission speed is significantly faster than that of the standard
serial ports, which operate at a maximum rate of 460.8 Kbaud.
The system console device can be either a standard alphanumeric terminal, terminal
server, TIP connection from another Sun system, or a local graphics monitor. The
default connection is through the serial management port (labeled SERIAL MGT) on
the back of the ALOM system controller card. You can also connect an alphanumeric
terminal to the serial (DB-9) connector (as TTYB) on the system back panel. A local
graphics monitor requires installation of a PCI graphics card, monitor, USB
keyboard, and mouse. You can also access the system console through a network
connection by means of the network management port.
The USB ports are accessible by connecting a USB cable to a back panel USB
connector. The connectors at each end of a USB cable are keyed so that you cannot
connect them incorrectly. One connector plugs in to the system or USB hub. The
other connector plugs in to the peripheral device. Up to 126 USB devices can be
connected to each controller simultaneously, through the use of USB hubs. The USB
ports provide power for smaller USB devices such as modems. Larger USB devices,
such as scanners, require their own power source.
Ultra-4 SCSI Port
The system includes a dedicated external Ultra-4 SCSI port. The port provides a
standard 68-pin, alternative 2 shielded connection, located on the back panel. The
port is accessible by connecting a SCSI cable to the Ultra-4 SCSI connector. The port
supports external storage devices capable of data transfer rates up to 320 Mbytes per
second.
22

The default console connection to the Netra 440 server is through the RJ-45 serial
management port (labeled SERIAL MGT) on the back panel of the ALOM system
controller card. This port operates only at 9600 baud.
Note – The serial management port is not a standard serial port. For standard serial
functionality, use the DB-9 port on the system back panel, which corresponds to
TTYB.
Chapter 1
System Overview
23
The ALOM system controller card features serial and 10BASE-T Ethernet interfaces
that provide multiple ALOM system controller software users with simultaneous
access to the Netra 440 server. ALOM system controller software users are provided
secure password-protected access to the system’s Solaris OS and OpenBoot console
functions. ALOM system controller users also have full control over power-on selftest (POST) and OpenBoot Diagnostics tests.
The ALOM system controller card runs independently of the host server, and
operates off of standby power from the server power supplies. The card features
on-board devices that interface with the server environmental monitoring subsystem
and can automatically alert administrators to system problems. Together, these
features enable the ALOM system controller card and ALOM system controller
software to serve as a lights out management tool that continues to function even
when the server operating system goes offline or when the server is powered off.
The ALOM system controller card connects to a dedicated slot on the motherboard
and provides the following ports (as shown in FIGURE 1-14) through an opening in
the system’s back panel:
■
Serial communication port by means of an RJ-45 connector (serial management
port, labeled SERIAL MGT)
■
10-Mbps Ethernet port by means of an RJ-45 twisted-pair Ethernet (TPE)
connector (network management port, labeled NET MGT) with green
Link/Activity LED
Serial Management Port
The serial management port (SERIAL MGT) enables you to set up a system console
device, without requiring you to configure an existing port. All power-on self-test
(POST) and ALOM system controller messages are directed to the serial
management port by default.
Network Management Port
The network management port (NET MGT) provides you with direct network access
to the ALOM system controller card and its firmware, as well as access to the system
console, power-on self-test (POST) output messages, and ALOM system controller
messages. You can use the network management port to perform remote
administration, including externally initiated resets (XIR).
For more information about the ALOM system controller card, refer to the Netra 440
Server System Administration Guide (817-3884-xx).

Netra 440 Server Product Overview • March 2006
PCI Cards and Buses
All system communication with storage peripherals and network interface devices is
mediated by four buses, using two Peripheral Component Interconnect (PCI) bridge
chips on the system motherboard. Each I/O bridge chip manages communication
between the system main interconnect bus and two PCI buses, giving the system a
total of four separate PCI buses. The four PCI buses support up to six PCI interface
cards and four motherboard devices.

Power Supplies
The motherboard distributes power from the power supplies to all internal system
components. The system’s four standard power supplies plug in directly to the
power distribution board, which then provides power to the motherboard through
two connectors. All four power supplies share the power demands of the system
equally.
26
Netra 440 Server Product Overview • March 2006
The Netra 440 server’s power supplies are hot-swappable units. They are designed
for fast, easy installation or removal by qualified service personnel, even while the
system is fully operational. Power supplies (PS) are installed in bays at the rear of
the system, as shown in FIGURE 1-16.
PS3
FIGURE 1-16
PS2
PS1
PS0
Power Supply Locations
The DC power supplies operate over an input range of -40 to -75 VDC, and the AC
power supplies operate over an input range of 90 to 264 VAC. Each power supply is
capable of providing up to 400W of DC power. The basic system configuration
comes with four power supplies installed. The system will continue to operate even
if a single power supply fails (known as a 3+1 configuration) or if two power
supplies fail (known as a 2+2 configuration). A 2+2 configuration is possible because
any two power supplies will satisfy the entire load of a fully-configured system.
The system can operate from either a single or a dual power source. If you operate
the system from a dual power source, each power feed would provide input to two
power supplies. In a dual-power source system, if a single power feed fails, the
system continues to receive power from the two power supplies powered from the
healthy feed. If one or two power supplies fail, the system continues to receive
adequate power from the healthy power supplies.
The power supplies provide +3.3V, +5V, +12V, -12V, and 5V standby outputs to the
system. Total system current load is shared equally between all supplies through
active current-sharing circuitry.
Each power supply has separate status LEDs to provide power and fault status
information, and to indicate hot-swap readiness. See “Power Supply LEDs” on
page 13 for a description of power supply LEDs.
Power supplies in a redundant configuration feature a hot-swap capability. You can
remove and replace a faulty power supply without shutting down the operating
system or turning off the system power. A power supply can be hot-swapped only
when at least two other power supplies are online and working properly.
Chapter 1
System Overview
27
In addition, the cooling fans in each power supply operate even if the power supply
fails by drawing power from the other power supplies through the motherboard to
provide adequate cooling to the system.
Note – You must issue a software command to prepare the power supply for
removal. This allows the system to verify that the remaining power supplies are
online and working properly, before lighting the OK-to-Remove LED. For more
information, refer to the Netra 440 Server Service Manual (817-3883-xx).
CPU/Memory Modules
The system motherboard provides slots for up to four CPU/memory modules. Each
CPU/memory module incorporates one UltraSPARC IIIi processor, and slots for up
to four dual inline memory modules (DIMMs). The CPUs in the system are
numbered from 0 to 3, depending on the slot where each CPU resides.
Note – CPU/memory modules on a Netra 440 server are not hot-swappable.

Netra 440 Server Product Overview • March 2006
The UltraSPARC IIIi processor is a high-performance, highly integrated superscalar
processor implementing the SPARC V9 64-bit architecture. The UltraSPARC IIIi
processor can support both 2D and 3D graphics, as well as image processing, video
compression and decompression, and video effects through the sophisticated Visual
Instruction Set extension (Sun VIS software). The VIS software provides high levels
of multimedia performance, including two streams of MPEG-2 decompression at full
broadcast quality with no additional hardware support.
The Netra 440 server employs a shared-memory multiprocessor architecture with all
processors sharing the same physical address space. The system processors, main
memory, and I/O subsystem communicate by means of a high-speed system
interconnect bus. In a system configured with multiple CPU/memory modules, all
main memory is accessible from any processor over the system bus. The main
memory is logically shared by all processors and I/O devices in the system.
However, memory is controlled and allocated by the CPU on its host module, that is,
the DIMMs on CPU/memory module 0 are managed by CPU 0.
Memory Modules
The Netra 440 server uses 2.5-volt, high-capacity double data rate dual inline
memory modules (DDR DIMMs) with error-correcting code (ECC). The system
supports DIMMs with 512-Mbyte, 1-Gbyte, and 2-Gbyte capacities. Each
CPU/memory module contains slots for four DIMMs. Total system memory ranges
from a minimum of 2 Gbytes (one CPU/memory module with four 512-Mbyte
DIMMs) to a maximum of 32 Gbytes (four modules fully populated with 2-Gbyte
DIMMs).
Within each CPU/memory module, the four DIMM slots are organized into groups
of two. The system reads from, or writes to, both DIMMs in a group simultaneously.
Therefore, DIMMs must be added in pairs. FIGURE 1-18 shows the DIMM slots and
DIMM groups on a Netra 440 server CPU/memory module. Adjacent slots belong to
the same DIMM group. The two groups are designated 0 and 1.

You must physically remove a CPU/memory module from the system before you
can install or remove DIMMs. The DIMMs must be added in pairs within the same
DIMM group, and each pair used must have two identical DIMMs installed—that is,
both DIMMs in each group must be from the same manufacturer and must have the
same density and capacity (for example, two 512-Mbyte DIMMs, two 1-Gbyte
DIMMs, or two 2-Gbyte DIMMs).
Note – Each CPU/memory module must be populated with a minimum of two
DIMMs, installed in either Group 0 or Group 1.
For guidelines and complete instructions on how to install DIMMs in a
CPU/memory module, refer to the Netra 440 Server Service Manual (817-3883-xx).
For more information about identifying the physical DIMMs referenced in system
console messages, refer to the Netra 440 Server Diagnostics and Troubleshooting Guide
(817-3886-xx).

Netra 440 Server Product Overview • March 2006
Memory Interleaving
You can maximize the system’s memory bandwidth by taking advantage of its
memory interleaving capabilities. The Netra 440 server supports two-way
interleaving. In most cases, higher interleaving results in improved system
performance. However, actual performance results can vary depending on the
system application. Two-way interleaving occurs automatically in any DIMM group
where the DIMM capacities do not match the capacities used in any other group. For
optimum performance, install identical DIMMs in all four slots of a CPU/memory
module.
Independent Memory Subsystems
Each Netra 440 server CPU/memory module contains an independent memory
subsystem. Memory controller logic incorporated into the UltraSPARC IIIi CPU
allows each CPU to control its own memory subsystem.
The Netra 440 server uses a shared memory architecture. During normal system
operations, the total system memory is shared by all CPUs in the system.
Ultra-4 SCSI Controller
The Netra 440 server uses an intelligent, two-channel 320-Mbyte per second Ultra-4
SCSI controller. Integrated into the motherboard, the controller resides on PCI Bus
2B and supports a 64-bit, 66-MHz PCI interface.
The on-board Ultra-4 SCSI controller provides hardware RAID mirroring (RAID 1)
capability with higher performance than conventional software RAID mirroring.
One pair of hard drives can be mirrored using the on-board Ultra-4 SCSI controller.
For more information about RAID configurations and configuring hardware
mirroring using the Ultra-4 SCSI controller, refer to the Netra 440 Server System
Administration Guide (817-3884-xx).
Ultra-4 SCSI Backplane
The Netra 440 server includes a single Ultra-4 SCSI backplane with connections for
up to four internal hard drives, all of which are hot-swappable.
Chapter 1
System Overview
31
The Ultra-4 SCSI backplane accepts four, low-profile (1.0-inch, 2.54-cm), UltraSCSI
hard drives capable of up to 320-Mbyte per second throughput. Each hard drive is
connected to the backplane through a standard 80-pin single connector attachment
(SCA) interface. Incorporating all power and signal connections into a single
connector, SCA technology makes it easy to add or remove hard drives from the
system. Drives using SCA connectors provide better serviceability than drives using
other types of connectors.
For information about installing or removing an UltraSCSI drive or drive backplane,
refer to the Netra 440 Server Service Manual (817-3883-xx).

Reliability, Availability, and
Serviceability Features
Reliability, availability, and serviceability (RAS) are aspects of a system’s design that
affect its ability to operate continuously and to minimize the time necessary to
service the system. Reliability refers to a system’s ability to operate continuously
without failures and to maintain data integrity. System availability refers to the
ability of a system to recover to an operational state after a failure, with minimal
impact. Serviceability relates to the time it takes to restore a system to service
following a system failure. Together, reliability, availability, and serviceability
features provide for near continuous system operation.
To deliver high levels of reliability, availability, and serviceability, the Netra 440
server offers the following features:

Hot-Swappable Components
Netra 440 hardware is designed to support hot-swapping of internal hard drives and
power supplies. By using the proper software commands, you can install or remove
these components while the system is running. Hot-swap technology significantly
increases the system’s serviceability and availability, by providing you with the
ability to do the following:
■
Increase storage capacity dynamically to handle larger work loads and to improve
system performance
■
Replace hard drives, fan trays, and power supplies without service disruption
3+1 or 2+2 Power Supply Redundancy
The system features four hot-swappable power supplies, two of which are capable of
handling the system’s entire load. Thus, the four power supplies provide “3+1” or
“2+2” redundancy, enabling the system to continue operating should one of the
power supplies fail (3+1 redundancy) or its DC power source fail (2+2 redundancy).
Note – Four power supplies must be present at all times to ensure proper system
cooling. Even if one power supply has failed, its fans obtain power from the other
power supply and through the motherboard to maintain proper system cooling.
For more information about power supplies, redundancy, and configuration rules,
see “Power Supplies” on page 26. For instructions on performing a power supply
hot-swap operation, see the Netra 440 Server Service Manual (817-3883-xx).

Netra 440 Server Product Overview • March 2006
System Controller
Sun Advanced Lights Out Manager (ALOM) system controller is a secure server
management tool that comes preinstalled on the Netra 440 server, in the form of a
module with preinstalled firmware. It lets you monitor and control your server over
a serial line or over a network. The ALOM system controller provides remote system
administration for geographically distributed or physically inaccessible systems. You
can connect to the ALOM system controller card using a local alphanumeric
terminal, a terminal server, or a modem connected to its serial management port, or
over a network using its 10BASE-T network management port.
When you first power on the system, the ALOM system controller card provides a
default connection to the system console through its serial management port. After
initial setup, you can assign an IP address to the network management port and
connect the network management port to a network. You can run diagnostic tests,
view diagnostic and error messages, reboot your server, and display environmental
status information using the ALOM system controller software. Even if the
operating system is down or the system is powered off, the ALOM system controller
can send an e-mail alert about hardware failures, or other important events that can
occur on the server.
The ALOM system controller provides the following features:
■
Default system console connection through its serial management port to an
alphanumeric terminal, terminal server, or modem
■
Network management port for remote monitoring and control over a network,
after initial setup
■
Remote system monitoring and error reporting, including diagnostic output
■
Remote reboot, power-on, power-off, and reset functions
■
Ability to monitor system environmental conditions remotely
■
Ability to run diagnostic tests using a remote connection
■
Ability to remotely capture and store boot and run logs, which you can review or
replay later
■
Remote event notification for overtemperature conditions, power supply faults,
system shutdown, or system resets
■
Remote access to detailed event logs
For more details about the ALOM system controller hardware, see “ALOM System
Controller Card and Ports” on page 23.
For information about configuring and using the ALOM system controller, refer to
the Netra 440 Server System Administration Guide (817-3884-xx).

Environmental Monitoring and Control
The Netra 440 server features an environmental monitoring subsystem designed to
protect the server and its components against:
■
■
■
■
■
Extreme temperatures
Lack of adequate airflow through the system
Operating with missing or misconfigured components
Power supply failures
Internal hardware faults
Monitoring and control capabilities are handled by the ALOM system controller
firmware. This ensures that monitoring capabilities remain operational even if the
system has halted or is unable to boot, and without requiring the system to dedicate
CPU and memory resources to monitor itself. If the ALOM system controller fails,
the operating system reports the failure and takes over limited environmental
monitoring and control functions.
The environmental monitoring subsystem uses an industry-standard I2C bus. The
I2C bus is a simple two-wire serial bus used throughout the system to allow the
monitoring and control of temperature sensors, fans, power supplies, status LEDs,
and the front panel rotary switch.
Temperature sensors are located throughout the system to monitor the ambient
temperature of the system, the CPUs, and the CPU die temperature. The monitoring
subsystem polls each sensor and uses the sampled temperatures to report and
respond to any overtemperature or undertemperature conditions. Additional I2C
sensors detect component presence and component faults.
The hardware and software together ensure that the temperatures within the
enclosure do not exceed predetermined “safe operation” ranges. If the temperature
observed by a sensor falls below a low-temperature warning threshold or rises
above a high-temperature warning threshold, the monitoring subsystem software
lights the system Service Required LEDs on the front and back panels. If the
temperature condition persists and reaches a critical threshold, the system initiates a
graceful system shutdown. In the event of a failure of the ALOM system controller,
backup sensors are used to protect the system from serious damage, by initiating a
forced hardware shutdown.
All error and warning messages are sent to the system console and logged in the
/var/adm/messages file. Service Required LEDs remain lit after an automatic
system shutdown to aid in problem diagnosis.
The power subsystem is monitored in a similar fashion. Polling the power supply
status periodically, the monitoring subsystem indicates the status of each supply’s
outputs, inputs, and presence.

Netra 440 Server Product Overview • March 2006
If a power supply problem is detected, an error message is sent to the system
console and logged in the /var/adm/messages file. Additionally, LEDs located on
each power supply light to indicate failures. The system Service Required LED lights
to indicate a system fault.
Automatic System Recovery
The system provides automatic system recovery (ASR) from component failures in
memory modules and PCI cards.
The ASR features enable the system to resume operation after experiencing certain
nonfatal hardware faults or failures. Automatic self-test features enable the system to
detect failed hardware components. An auto-configuring capability designed into
the system’s boot firmware enables the system to unconfigure failed components
and to restore system operation. As long as the system can operate without the
failed component, the ASR features enable the system to reboot automatically,
without operator intervention.
During the power-on sequence, if a faulty component is detected, the component is
marked as failed and, if the system can function, the boot sequence continues. In a
running system, some types of failures can bring down the system. If this happens,
the ASR functionality enables the system to reboot immediately if it is possible for
the system to detect the failed component and operate without it. This prevents a
faulty hardware component from keeping the entire system down or causing the
system to crash repeatedly.
Note – ASR functionality is not enabled until you activate it. Control over the
system ASR functionality is provided by several OpenBoot commands and
configuration variables. For additional information, refer to the Netra 440 Server
System Administration Guide.

For more information, refer to the Netra 440 Server System Administration Guide
(817-3884-xx).
ALOM Watchdog Mechanism and XIR
To detect and respond to a system hang, should one ever occur, the Netra 440 server
features an ALOM “watchdog” mechanism, which is a timer that is continually reset
as long as the operating system and user application are running. In the event of a
system hang, the operating system is no longer able to reset the timer. The timer will
then expire and cause an automatic externally initiated reset (XIR), eliminating the
need for operator intervention. When the ALOM watchdog mechanism issues the
XIR, debug information is displayed on the system console.
The XIR feature is also available for you to invoke manually at the ALOM system
controller prompt. You use the ALOM system controller reset -x command
manually when the system is unresponsive and an L1-A (Stop-A) keyboard
command or alphanumeric terminal Break key does not work. When you issue the
reset -x command manually, the system is immediately returned to the OpenBoot
ok prompt. From there, you can use OpenBoot commands to debug the system.
For more information, refer to the Netra 440 Server System Administration Guide (8173884-xx) and the Netra 440 Server Diagnostics and Troubleshooting Guide (817-3886-xx).

Support for RAID Storage
Configurations
By attaching one or more external storage devices to the Netra 440 server, you can
use a redundant array of independent drives (RAID) software application such as
Solstice DiskSuite™ or VERITAS Volume Manager to configure system drive storage
in a variety of different RAID levels. Configuration options include RAID 0
(striping), RAID 1 (mirroring), RAID 0+1 (striping plus mirroring), RAID 1+0
(mirroring plus striping), and RAID 5 (striping with interleaved parity). You choose
the appropriate RAID configuration based on the price, performance, reliability, and
availability goals for your system. You can also configure one or more hard drives to
serve as “hot spares” to fill in automatically in the event of a hard drive failure.
In addition to software RAID configurations, you can set up a hardware RAID 1
(mirroring) configuration for any pair of internal hard drives using the on-board
Ultra-4 SCSI controller, providing a high-performance solution for hard drive
mirroring.
For more information, refer to the Netra 440 Server System Administration Guide (8173884-xx).
Error Correction and Parity Checking
DIMMs employ error-correcting code (ECC) to ensure high levels of data integrity.
The system reports and logs correctable ECC errors. (A correctable ECC error is any
single-bit error in a 128-bit field.) Such errors are corrected as soon as they are
detected. The ECC implementation can also detect double-bit errors in the same
128-bit field and multiple-bit errors in the same nibble (4 bits). In addition to
providing ECC protection for data, parity protection is also used on the PCI and
UltraSCSI buses, and in the UltraSPARC IIIi CPU internal caches.

Sun Java System Cluster Software
Sun Java System Cluster software lets you connect up to eight Sun servers in a
cluster configuration. A cluster is a group of nodes that are interconnected to work as
a single, highly available and scalable system. A node is a single instance of Solaris
software. The software can be running on a standalone server or on a domain within
a standalone server. With Sun Java System Cluster software, you can add or remove
nodes while online, and mix and match servers to meet your specific needs.
Sun Java System Cluster software delivers high availability through automatic fault
detection and recovery, and scalability, ensuring that mission-critical applications
and services are always available when needed.
With Sun Java System Cluster software installed, other nodes in the cluster
automatically take over and assume the workload when a node goes down. The
software delivers predictability and fast recovery capabilities through features such
as local application restart, individual application failover, and local network
adapter failover. Sun Java System Cluster software significantly reduces downtime
and increases productivity by helping to ensure continuous service to all users.
The software lets you run both standard and parallel applications on the same
cluster. It supports the dynamic addition or removal of nodes, and enables Sun
servers and storage products to be clustered together in a variety of configurations.
Existing resources are used more efficiently, resulting in additional cost savings.
Sun Java System Cluster software allows nodes to be separated by up to 10
kilometers. This way, in the event of a disaster in one location, all mission-critical
data and services remain available from the other unaffected locations.
For more information, see the documentation supplied with the Sun Java System
Cluster software.
