This section describes suggested PCI/XAUI card features and configurations. See FIGURE 1-3 for back panel locations of the PCI slots.
Slot 0 and Slot 1 are 133MHZ PCI-X slots and support form factor PCI-X cards. The maximum power for each slot is 25 Watts.
Slot 2 and Slot 3 are x8 PCIe slots that have x16 mechanical connectors. These slots support form factor PCIe cards, and support the highest power 75 Watt PCIe card. However, only one 75 Watt PCIe card can be installed in the server. It is suggested to install the 75 Watt card in Slot 2 for better cooling.
PCIe Slots 4-9 are x8 PCIe slots and support low profile PCIe cards and Max power for each slot is 25 Watts. PCIe Slot 4 and PCIe Slot 5 are combination slots with XAUI4 and XAUI5.
If a XAUI card is installed in the XAUI4 slot, the PCIe Slot 4 cannot be used, and the Ethernet Port 1 on the motherboard will be disabled. If a XAUI card is installed in the XAUI5 slot, the PCIe Slot 5 cannot be used and the Ehternet Port 0 on the motherboard will be disabled.
To balance the PCIe bus bandwidth from the upstream of the PCIe buses, it is suggested to limit the numbers of high bandwidth PCIe cards installed in the server. It is also suggested to install the high bandwidth PCIe cards in the assigned slots. The following are two examples:
Example 1 – If one or two XAUI cards are installed in the server, it is suggested to install two high bandwidth PCIe cards: one in Slot 2 and in Slot 8.
Example 2 – If there are no XAUI cards installed in the server, it is suggested to install four high bandwidth PCIe cards: one in Slot 2, 4, 8, and 9.
The Sun Netra T5440 server is based on a new four rack unit (4U) chassis.
Note - For chassis dimensions and other specifications, refer to the Sun Netra T5440 Server Site Planning Guide. |
The Sun Netra T5440 server has the following boards installed in the chassis:
Motherboard – The motherboard includes two CMP modules, slots for 16 FB‐DIMMs, memory control subsystems, and all service processor (ILOM) logic. In addition, a removable SCC module contains all MAC addresses, host ID, and ILOM configuration data. When replacing the motherboard, the SCC module can be transferred to a new board to retain system configuration data. However, your OpenBoot PROM configuration information is stored on the NVRAM on the motherboard, and the NVRAM cannot be transferred to the new motherboard, so you should record your OpenBoot PROM configuration information before replacing the motherboard.
The service processor (ILOM) subsystem controls the server power and monitors server power and environmental events. The ILOM controller draws power from the server’s 3.3V standby supply rail, which is available whenever the system is receiving main input power, even when the system is turned off.
Note - CPUs can not be upgraded or replaced on the motherboard. If a CPUs fails, the motherboard must be replaced as a field-replaceable unit (FRU). |
Memory mezzanine assembly – This is an option that requires purchasing an upgrade. This assembly provides an additional 16 memory slots.
Power distribution board – This board distributes main 12V power from the power supplies to the rest of the system. This board is directly connected to the motherboard through a bus bar and ribbon cable.
Power supply backplane – This board carries 12V power from the power supplies to the power distribution board with a pair of bus bars.
Fan power boards – This board carries power to the system fan modules, and is cabled to the power distribution board.
SAS backplane – This board includes the connectors for the 12 SAS hard drives.
Each drive has its own Power/Activity, Fault, and Ready-to-Remove LEDs.
System Alarm Board – This board contains the interconnect for the front I/O board, Power and Locator buttons, and system/component status LEDs.
PCI auxiliary board (PCI_AUX) – This board has two PCIe slots and two PCI-X slots to support full length and full height PCIe/PCI-X cards. One Intel 41210 PCIe to PCI-X chip is used to convert the PCIe bus to two PCI-X buses. One PLX8525 PCIe switch is used to expand two PCIe slots. All the PCIe signal/buses are from the PCI mezzanine board, through the cables.
PCI mezzanine board (PCI_MEZZ) – This board is designed with six x8 PCIe slots and two XAUI slots (combo) to support six low profile PCIe cards or four low profile PCIe cards and two XAUI cards. One PLX8533 PCIe switch is used to expand the PCIe slots.
DVD interface board – This board connects the optical media drive to the motherboard.
PCIe/XAUI risers – There are three risers per system, each attached to the rear of the motherboard.
Note - 10‐Gbit Ethernet XAUI cards are only supported in Slots 4 and 5. |
The Sun Netra T5440 server has the following cables:
Ribbon cable, connected between the power distribution board (PDB) and the motherboard
Two power and signals cables are used between PDB and PCI_AUX board
One x4 PCIe cable, one x8 PCIe cable, and power cable are connected between the PCI Mezz board and the PCI-AUX board
An alarm cable connects the PDB to the DB15 connector in the rear of the server
A cable is used to connect the PDB to the SYS/Alarm LED board in the front of the server
The server front panel contains a recessed system power button, system status and fault LEDs, Locator button and LED, and Telco Alarm Status LEDs. The front panel also provides access to internal hard drives, the removable media drive, and the two front USB ports.
Caution - Do not open the fron bezel while the server is on a flat surface. If opened on a flat surface, the bezel hinges will break. |
The server must either be rackmounted, OR the front of the server (including bezel hinges) must extend over the edge of a table or desktop surface before opening the bezel.

The UltraSPARC T2 Plus multicore processor is the basis of the Sun Netra T5440 server. The UltraSPARC T2 processor is based on chip multithreading (CMT) technology that is optimized for highly threaded transactional processing. The UltraSPARC T2 processor improves throughput while using less power and dissipating less heat than conventional processor designs.
Depending on the model purchased, each processor chip has four, six, or eight UltraSPARC cores. Each core has two integer pipelines. Each pipeline runs four threads, for a total of eight threads per core.
Additional processor components, such as L1 cache, L2 cache, memory access crossbar, memory controllers, and the I/O interface have been carefully tuned for optimal performance.
The Sun Netra T5440 server expands the CoolThreads family to include dual socket systems. The server delivers extremely high compute density with up to 128 threads in 4 rack units.
The server provides advanced power management through the UltraSPARC T2 power management features that work at both the core and the memory levels of the processor. These features include the ability to reduce instruction issue rates, parking of idle threads and cores, and the ability to turn off clocks in both cores and memory to reduce power consumption.
The Sun Netra T5440 server is preinstalled with the Solaris 10 OS, and offers the following Solaris OS features:
Stability, high performance, scalability, and precision of a mature 64-bit operating system
Support for over 5,000 leading technical and business applications, and thousands of Java based services
Solaris Containers – Isolate software applications and services using flexible, software-defined boundaries
DTrace – A comprehensive dynamic tracing framework for tuning applications and troubleshooting systemic problems in real time
Predictive Self-Healing – Capability that automatically diagnoses, isolates, and recovers from many hardware and application faults
Security – Advanced security features designed to protect the enterprise at multiple levels
Network Performance – Completely rewritten TCP/IP stack dramatically improves the performance and scalability of your networked services
You can use the preinstalled Solaris 10 OS, or reinstall a supported version of the Solaris 10 OS from your network, CD, or downloaded copy. In some cases, if you reinstall the Solaris OS, you must also install patches. Refer to the Sun Netra T5440 Server Product Notes for information on the supported OS releases for your server.
The UltraSPARC T2 Plus multicore, multithreaded, processors provide hardware-assisted acceleration of symmetric, asymmetric, hashing, and random number generation cryptographic operations as follows:
The Solaris 10 OS provides the multithreaded device driver that supports the hardware-assisted cryptography.
The Sun Netra T5440 server supports the use of Logical Domains (LDoms) technology. Through the use of the Solaris OS and the built-in server firmware, and by installing the Logical Domains Manager software, you can virtualize the compute services that run on your server. LDoms technology is open source technology, and is included at no additional cost.
A logical domain is a discrete, logical grouping with its own operating system, resources, and identity within a single computer system. Each logical domain can be created, destroyed, reconfigured, and rebooted independently, without requiring a power cycle of the server.
You can run a variety of applications software in different logical domains and keep them independent for performance and security purposes.
Each logical domain can be managed as an entirely independent machine with its own resources, such as:
Each logical domain can interact only with those server resources made available to it, and the configuration is controlled using the Logical Domains Manager.
For more information on Logical Domains, refer to the Logical Domains (LDoms) Administration Guide.
The Integrated Lights Out Manager (ILOM) feature is a service processor, built into the server, that enables you to remotely manage and administer the server. The ILOM software is preinstalled as firmware, and initializes as soon as you apply power to the system.
ILOM enables you to monitor and control your server over an Ethernet connection (supports SSH), or by using a dedicated serial port for connection to a terminal or terminal server. ILOM provides a command-line interface and a browser-based interface to remotely administer geographically distributed or physically inaccessible machines. In addition, ILOM enables you to run diagnostics (such as POST) remotely that would otherwise require physical proximity to the server’s serial port.
You can configure ILOM to send email alerts of hardware failures and warnings, and other events related to the server. The ILOM circuitry runs independently of the server, using the server’s standby power. Therefore, ILOM firmware and software continue to function when the server operating system goes offline or when the server is powered off. ILOM monitors the following Sun Netra T5440 server conditions:
In addition to the ILOM CLI and browser interface (BI), you can set up the server to use an ALOM CMT compatibility CLI. The ALOM CMT compatibility CLI provides commands that approximate the ALOM CMT CLI that is a system controller interfaced provided on some previous servers.
For information about configuring and using the ILOM service processor, refer to the latest Integrated Lights Out Management (ILOM) User’s Guide and the Sun Integrated Lights Out Manager 2.0 (ILOM 2.0) Supplement for the Sun Netra T5440 Server.
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 Netra T5440 server offers the following features:
Sun Netra T5440 server hardware is designed to support hot-plugging of the chassis-mounted 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 and hot-plug 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 Netra T5440 server features an environmental monitoring subsystem that 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 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 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. 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.
You can set up 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 Netra T5440 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. Software RAID applications such as VERITAS Volume Manager are not included with this server. You must obtain and license them separately.
The UltraSPARC T2 Plus 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 L2 cache has parity protection on the tags, and ECC protection on the data.
Advanced ECC corrects up to 4 bits in error on nibble boundaries, as long as the bits are all in the same DRAM. If a DRAM fails, the DIMM continues to function.
The Sun Netra T5440 server provides 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 Netra T5440 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.
