CHAPTER 1 Sun Fire T1000 Server Overview This chapter provides an overview of the features of the Sun Fire T1000 server. The following topics are covered: ■ ■ “Sun Fire T1000 Server Features” on page 1 “Chassis Identification” on page 6 Sun Fire T1000 Server Features The Sun Fire T1000 server FIGURE 1-1 is a high-performance, entry-level server that is highly scalable and very reliable.
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.
TABLE 1-1 lists feature specifications for the Sun Fire T1000 server. TABLE 1-1 Sun Fire T1000 System Features Feature Description Processor 1 UltraSPARC T1 multicore processor (6 or 8 cores) Memory 8 slots that can be populated with one of the following types of DDR-2 DIMMs: • 512 MB (4 GB maximum) • 1 GB (8 GB maximum) • 2 GB (16 GB maximum) Ethernet ports 4 ports, 10/100/1000 Mbit auto-negotiating.
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.
■ 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.
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.

Until the faulty component is replaced, the system can boot using memory that was not disabled. Note – You can use ASR commands to display and control disabled components. See “Managing System Components with Automatic System Recovery Commands” on page 40.
The PSH console message provides the following information: ■ ■ ■ ■ ■ ■ ■ Type Severity Description Automated Response Impact Suggested Action for System Administrator Details If the Solaris OS PSH facility has detected a faulty component, use the fmdump command to identify the fault. Note – Additional predictive self-healing information is available at: http://www.sun.com/msg.
▼ To Use the fmdump Command to Identify Faults The fmdump command displays the list of faults detected by the Solaris PSH facility. Use this command for the following reasons: ■ To see if any faults have been detected by the Solaris PSH facility. ■ If you need to obtain the fault message ID (SUNW-MSG-ID) for detected faults. ■ To verify that the replacement of a FRU has cleared the fault and not generated any additional faults.
Memory module errors exceeded acceptable levels Type Fault Severity Major Description The Solaris(TM) Fault Manager has determined that the number of correctable (single bit) memory errors reported against a memory DIMM module indicates a fault requiring repair action is present. Automated Response The system will attempt to remove the affected page of memory from service.
If Customer Enabled Services apply to the product then refer to the FRU replacement procedures in the appropriate service manual. c. Follow the suggested actions to repair the fault. Collecting Information From Solaris OS Files and Commands With the Solaris OS running on the Sun Fire T1000 server, you have the full compliment of Solaris OS files and commands available for collecting information and for troubleshooting.
The /var/adm directory contains several message files. The most recent messages are in the /var/adm/messages file. After a period of time (usually every ten days), a new messages file is automatically created. The original contents of the messages file are rotated to a file named messages.1. Over a period of time, the messages are further rotated to messages.2 and messages.3, and then deleted. 1. Log in as superuser. 2. Issue the following command: # more /var/adm/messages 3.
The ASR commands (TABLE 2-7) enable you to view, and manually add or remove components from the ASR blacklist. These commands are run from the ALOM sc> prompt. TABLE 2-7 ASR Commands Command Description showcomponent* Displays system components and their current state. enablecomponent asrkey Removes a component from the asr-db blacklist, where asrkey is the component to enable. disablecomponent asrkey Adds a component to the asr-db blacklist, where asrkey is the component to disable.
