The UltraSPARC® T1 multicore processor is the basis of the Sun SPARC Enterprise T2000 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 four 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 as L1 cache, L2 cache, memory access crossbar, DDR2 memory controllers, and a JBus I/O interface have been carefully tuned for optimal performance. See FIGURE 2.
The Sun SPARC Enterprise T2000 server running the Solaris 10 OS provides several new performance enhancing technologies with its sun4v architecture and multicore multithreaded UltraSPARC T1 multicore processor.
Some of these enhancements are:
The Sun SPARC Enterprise T2000 server is preinstalled with the Solaris 10 OS, and offers the following Solaris OS features:
If you prefer to install the Solaris OS rather then use the preinstalled Solaris OS, you can do so. The Sun SPARC Enterprise T2000 server supports Solaris 10 OS. For possible updates to supported Solaris releases, refer to the Sun SPARC Enterprise T2000 Server Product Notes.
The Sun SPARC Enterprise T2000 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 Management (ALOM CMT) feature is a system controller that enables you to remotely manage and administer the Sun SPARC Enterprise T2000 server.
The ALOM CMT software is preinstalled as firmware, and 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 a dedicated serial port for connection to a terminal or terminal server. 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 Sun SPARC Enterprise T2000 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 T2000 server offers the following features:
For more information about using RAS features, refer to the Sun SPARC Enterprise T2000 Server Administration Guide.
Sun SPARC Enterprise T2000 server hardware is designed to support hot-swapping of the chassis-mounted hard drives, fan units, 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 the ability to replace hard drives, fan units, and power supplies without service disruption.
The Sun SPARC Enterprise T2000 server features two hot-swappable power supplies, enabling the system to continue operating should one of the power supplies fail or if one power source fails.
The Sun SPARC Enterprise T2000 server also has a single hot-swappable blower unit that works in conjunction with the power supply fans to provide cooling for the internal disk drives. If the blower unit fails, the three functioning fan units provide enough cooling to keep the system running.
The Sun SPARC Enterprise T2000 server features three hot-swappable system fans. The fans enable the system to continue operating with adequate cooling in the event that one of the fans fails.
The Sun SPARC Enterprise T2000 server features an environmental monitoring subsystem protects 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 back 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 system controller, backup sensors protect the system from serious damage, by initiating a forced hardware shutdown.
All error and warning messages are logged in the ALOM CMT event log and are optionally sent to the system controller (SC) system console. 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 logged in the ALOM CMT event log and optionally sent to the SC system console. Additionally, LEDs located on each power supply light to indicate failures. The system Service Required LED lights to indicate a system fault.
You can set up a hardware RAID 1 (mirroring) and hardware RAID 0 (striping) configurations for any pair of internal hard drives, providing a high-performance solution for hard drive mirroring.
By attaching one or more external storage devices to the Sun SPARC Enterprise T2000 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.
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 Sun SPARC Enterprise T2000 server features the latest fault management technologies. The Solaris 10 OS architecture provides a means 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 Sun SPARC Enterprise 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.
The Sun SPARC Enterprise T2000 server uses a space-saving 2U-high rackmountable enclosure that can be installed into a variety of industry standard racks.
