Chip-Multitheaded (CMT) Multicore Processor and Memory Technology
The UltraSPARC®T1 multicore processor is the basis of the Sun Fire T1000 server.
The UltraSPARC T1 processor is based on chip multithreading (CMT) technology
that is optimized for highly threaded transactional processing. The UltraSPARC T1
processor improves throughput while using less power and dissipating less heat
than conventional processor designs.
Depending on the model purchased, the processor has six or eight UltraSPARC
cores. Each core equates to a 64-bit execution pipeline capable of running four
threads. The result is that the 8-core processor handles up to 32 active threads
concurrently.
Additional processor components, such the
cache, and the Jbus I/O interface have been carefully tuned for optimal
performance.

Remote Manageability With ALOM
The Sun Advanced Lights Out Manager (ALOM) feature is a system controller (SC)
that enables to you remotely manage and administer the Sun Fire T1000 server.
Chapter 1 Sun Fire T1000 Server Overview 3
The ALOM-CMT software is preinstalled as firmware, and therefore, ALOM
initializes as soon as you apply power to the system. You can customize ALOM to
work with your particular installation.
ALOM enables you to monitor and control your server over a network, or by using
a dedicated serial port for connection to a terminal or terminal server. ALOM
provides a command-line interface that you can use to remotely administer
geographically distributed or physically inaccessible machines. In addition, ALOM
enables you to run diagnostics (such as POST) remotely that would otherwise
require physical proximity to the server’s serial port.
You can configure ALOM to send email alerts of hardware failures, hardware
warnings, and other events related to the server or to ALOM. The ALOM circuitry
runs independently of the server, using the server’s standby power. Therefore,
ALOM firmware and software continue to function when the server operating
system goes offline or when the server is powered off. ALOM monitors the
following Sun Fire T1000 server components:
■ Hard disk drive status
■ Enclosure thermal conditions
■ Power supply status
■ Voltage levels
■ Faults detected by POST (Power-On Self-Test)
■ Solaris OS Predictive Self Healing (PSH) diagnostic facilities
For information about configuring and using the ALOM system controller, refer to
the Sun Fire T1000 Server Advanced Lights Out Manager (ALOM) Guide.
System Reliability, Availability, and Serviceability
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 Sun Fire T1000
server offers the following features:
■ Environmental monitoring
■ Error detection and correction for improved data integrity
■ Easy access for most component replacements
■ Extensive POST tests that automatically delete faulty components from the
configuration.
4 Sun Fire T1000 Server Service Manual • January 2006
■ PSH automated run time diagnosis capability that takes faulty components off
line.
For more information about using RAS features, refer to the Sun Fire T1000 Server
System Administration Guide.
Environmental Monitoring
The Sun Fire T1000 server features an environmental monitoring subsystem
designed to protect the server and its components against:
■ Extreme temperatures
■ Lack of adequate airflow through the system
■ Power supply failure
■ Hardware faults
Temperature sensors throughout the system monitor the ambient temperature of the
system and internal components. The software and hardware ensure that the
temperatures within the enclosure do not exceed predetermined safe operating
ranges. If the temperature observed by a sensor falls below a low-temperature
threshold or rises above a high-temperature threshold, the monitoring subsystem
software lights the amber 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.
All error and warning messages are sent to the ALOM system controller system
console and logged in the ALOM log file. Additionally, some FRUs such as the
power supply provide LEDs that indicate a failure within the FRU.
Additionally, the power supply contains an LED that is lit to indicate a failure within
the power supply.
Error Correction and Parity Checking
The SPARC T1 multicore processor provides parity protection on its internal cache
memories, including tag parity and data parity on the D-cache and I-cache. The
internal 3MB L2 cache has parity protection on the tags, and ECC protection of the
data.
Advanced ECC, also called Chipkill, detects up to 4-bits in error.
Chapter 1 Sun Fire T1000 Server Overview 5
Predictive Self-Healing
The Sun Fire T1000 server features the latest fault management technologies. With
the Solaris 10 Operating System (OS), Sun is introducing a new architecture for
building and deploying systems and services capable of predictive self-healing. Selfhealing technology enables Sun systems to accurately predict component failures
and mitigate many serious problems before they actually occur. This technology is
incorporated into both the hardware and software of the Sun Fire T2000 server.
At the heart of the predictive self-healing capabilities is the Solaris Fault Manager, a
new service that receives data relating to hardware and software errors, and
automatically and silently diagnoses the underlying problem. Once a problem is
diagnosed, a set of agents automatically responds by logging the event, and if
necessary, takes the faulty component offline. By automatically diagnosing
problems, business-critical applications and essential system services can continue
uninterrupted in the event of software failures, or major hardware component
failures.

Sun Fire T1000 Server Diagnostics
This chapter describes the diagnostics that are available for monitoring and
troubleshooting the Sun Fire T1000 server. This chapter does not provide detailed
troubleshooting procedures, but instead describes the Sun Fire T1000 server
diagnostics facilities and how to use them.
This chapter is intended for technicians, service personnel, and system
administrators who service and repair computer systems.
The following topics are covered:
■ “Overview of Sun Fire T1000 Server Diagnostics” on page 9
■ “Using LEDs to Identify the State of Devices” on page 14
■ “Using ALOM For Diagnosis and Repair Verification” on page 17
■ “Running POST” on page 27
■ “Using the Solaris Predictive Self-Healing Feature” on page 35
■ “Collecting Information From Solaris OS Files and Commands” on page 39
■ “Managing System Components with Automatic System Recovery Commands”
on page 40
■ “Exercising the System with SunVTS” on page 43
Overview of Sun Fire T1000 Server Diagnostics
There are a variety of diagnostic tools, commands, and indicators you can use to
troubleshoot a Sun Fire T1000 server.
■ LEDs – provide a quick visual notification of the status of the server and of some
of the FRUs.
9
■ ALOM-CMT firmware – is the system firmware that runs on the system
controller. In addition to providing the interface between the hardware and OS,
ALOM also tracks and reports the health of key server components. ALOM works
closely with POST and Solaris predictive self healing technology to keep the
system up and running even when there is a faulty component.
■ Power-On self-test (POST) – Performs diagnostics on system components upon
system reset to ensure the integrity of those components. POST is configureable
and works with ALOM to take faulty components offline if needed and blacklist
them in the asr-db.
■ Solaris OS predictive self healing (PSH) – Continuously monitors the health of
the CPU and memory, and works with ALOM to take a faulty component offline
if needed.
■ Log files and console messages – Provide the standard Solaris OS log files and
investigative commands that can be accessed and displayed on the device of your
choice.
■ SunVTS™ – is an application you can run that exercises the system, provides
hardware validation, and discloses possible faulty components with
recommendations for repair.
The LEDs, ALOM, Solaris OS PSH, and many of the log files and console messages
are integrated. For example, a fault detected by the Solaris PSH software will display
the fault, log it, pass information to ALOM where it is logged, and depending on the
fault, might result in the illumination of one or more LEDs.
The diagnostic flowchart in
FIGURE 2-1 and TABLE 2-1 describe an approach for using
the servers diagnostics that is likely identify a faulty field-replaceable unit (FRU).
The diagnostics you use, and the order in which you use them, depend on the nature
of the problem you are troubleshooting, so you might not follow this flow step-bystep.
The flowchart assumes that you have already performed some rudimentary
troubleshooting such as verification of proper installation, visual inspection of cables
and power, and possibly reset server (For details, refer to the Sun Fire T1000 Server
Installation Guide and Sun Fire T1000 Server Administration Guide .
Use this flow chart to understand what diagnostics are available to troubleshoot
faulty hardware, and use TABLE 2-1 to find more information about each diagnostic
in this chapter.
For many faults, service can be deferred, either because the faulty component has
been asr'd out, the fault is being corrected, or the fault is predictive

8. Identify the cause
of the over
temperature
condition
The over temperature condition may be caused
excessive ambient room temperature, an
overheating power supply or a faulty fan tray
assembly.
• If ambient room temperature is too high, reduce
room temperature.
• If over temperature condition still exists, go to
Action 9.
• If over temperature condition does not exist, go
to Action 10.
9. Identify the faulty
FRU.
The FRUs require that you shut down the server to
perform a cold-swap.
After replacing the faulty FRU, go to Action 14.
10. Check the Solaris
log files for fault
information.
The Solaris message buffer and log files record
system events and can provide information about
faults.
• If system messages indicate a faulty device,
replace the FRU (Action 11).
• To obtain more diagnostic information, got to
Action 7.
11. Run POST. POST perforsm basic tests of the server components
and reports faulty FRUs.
• If POST indicates a faulty FRU, replace the FRU
(Action 9).
• If POST does not indicate a faulty FRU, go to
Action 12.
12. Run SunVTS. SunVTS provides tests used to exercise and
diagnose FRUs. To run SunVTS, the server must be
running the Solaris OS.
• If SunVTS reports a faulty device replace the
FRU (Action 9).
• If SunVTS does not report a faulty device, go to
Action 11.

verify the functionality of the system components.
Two useful commands are:
• The ALOM showfaults command
• The ASR showcomponents command
If the FRU is blacklisted, you can manually remove
it from the black list with the enablecomponent
command.
If the fault is cleared, and the component is not
blacklisted, the repair is verified well enough to
boot the server. For added assurance, you can run
the SunVTS diagnostic software.
The majority of hardware faults are detected by the
server’s diagnostics. In rare cases it is possible that
a problem requires additional troubleshooting. If
you are unable to determine the cause of the
problem, contact Sun for support.
