This chapter describes the features of the server.
The Sun SPARC Enterprise T1000 server is a scalable and reliable high-performance, entry-level server, offering the following characteristics:
The UltraSPARC T1 multicore processor is the basis of the Sun SPARC Enterprise T1000 server. The UltraSPARC T1 processor is based on chip multithreading (CMT) technology that is optimized for highly threaded transactional processing. The 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 (FIGURE 2), such as L1 cache, L2 cache, memory access crossbar, DDR2 memory controllers, and a JBus I/O interface have been carefully tuned for optimal performance.
The Sun SPARC Enterprise T1000 server introduces several new technologies with its sun4v architecture and multicore multithreaded UltraSPARC T1 multicore processor.
Some of these enhancements are:
The Sun SPARC Enterprise T1000 server is preinstalled with the Solaris 10 OS, and offers the following Solaris OS features:
If you prefer to install the Solaris OS rather than use the preinstalled Solaris OS, you can do so. The Sun SPARC Enterprise T1000 server uses the Solaris 10 OS. For specific supported Solaris releases, refer to the Sun SPARC Enterprise T1000 Server Product Notes.
The server is preinstalled with Java Enterprise System software and includes a free 90-day evaluation license for the following Java Enterprise System software applications:
To gain the benefits of the Java Enterprise System, you can buy a subscription license for a Java Enterprise System Suite, or a combination of Java System Suites.
The UltraSPARC T1 multicore processor provides hardware-assisted acceleration of RSA and DSA cryptographic operations. The Solaris 10 Operating System provides the multithreaded device driver (ncp device driver) that supports the hardware-assisted cryptography.
The Advanced Lights Out Manager (ALOM CMT) feature is a system controller that enables you to remotely manage and administer the Sun SPARC Enterprise T1000 server.
The ALOM CMT software is preinstalled as firmware, and therefore, ALOM CMT initializes as soon as you apply power to the system. You can customize
ALOM CMT to work with your particular installation.
ALOM CMT enables you to monitor and control your server over a network, or by using the dedicated serial port. ALOM CMT provides a command-line interface that you can use to remotely administer geographically distributed or physically inaccessible machines. In addition, ALOM CMT 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 CMT to send email alerts of hardware failures, hardware warnings, and other events related to the server or to ALOM CMT. The ALOM CMT circuitry runs independently of the server, using the server's standby power. Therefore, ALOM CMT firmware and software continue to function when the server operating system goes offline or when the server is powered off. ALOM CMT monitors the following server components:
For information about configuring and using the ALOM system controller, refer to the Advanced Lights Out Management (ALOM) CMT guide.
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 SPARC Enterprise T1000 server offers the following features:
For more information about using RAS features, refer to the Sun SPARC Enterprise T1000 Server Administration Guide.
The Sun SPARC Enterprise T1000 server features an environmental monitoring subsystem designed to protect the server and its components against:
Temperature sensors are located throughout the system to 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 operation 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 rear panel. 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 controller (sc), system console, and logged in the ALOM CMT console log 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 by monitoring power supplies and reporting any fault in the front and rear panel LEDs.
If a power supply problem is detected, an error message is sent to the SC system console and logged in the ALOM CMT console log file. Additionally, LEDs located on each power supply light to indicate failures. The system Service Required LED lights to indicate a system fault.
The UltraSPARC 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 on the data.
Advanced ECC, also called chipkill, corrects up to 4-bits in error on nibble boundaries as long as they are all in the same DRAM. If a DRAM fails, the DIMM continues to function.
The server features the latest fault management technologies based on a new architecture for building and deploying systems and services capable of Predictive Self-Healing. Self-healing technology enables 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 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 logs 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.
The server uses a space-saving 1U-high rackmountable enclosure that can be installed into a variety of industry standard racks.
