Server Highlights
The SPARC Enterprise T5120 (FIGURE: SPARC Enterprise T5120 Server on page 3)
and T5220 (FIGURE: SPARC Enterprise T5220 Server on page 3) servers are scalable,
reliable, high-performance, entry-level servers, optimized for enterprise data centers.
These servers offer the following key features:
■ The UltraSPARC T2 multicore processor with CoolThreads technology for
high-throughput and energy savings.
■ High levels of system uptime through the processor and memory
reliability-availability-serviceability (RAS) features, coupled with redundancy of
some systems components, support for hardware RAID (0+1), and the Predictive
Self-Healing features of the Solaris 10 Operating System (Solaris OS).
■ Both servers come in a space efficient, rack-optimized form factor chassis, 1U for
the SPARC Enterprise T5120 server, and 2U for the SPARC Enterprise T5220
server.
■ Investment protection with SPARC V9 binary application compatibility and the
Solaris 10 OS. The Solaris 10 OS also provides features such as Solaris Predictive
Self-Healing, Solaris Dynamic Tracing, and support across UltraSPARC platforms.
■ Unified server management though the use of the Integrated Lights Out Manager
(ILOM) interface. ILOM integrates and manages CoolThreads and x64 platforms
with the same tool set, and in heterogeneous environments, using industry
standard element management tools and enterprise frameworks.
The following figure shows the SPARC Enterprise T5120 server chassis as viewed
from the front and top.

The UltraSPARC T2 multicore processor is the basis of the SPARC Enterprise T5120
and T5220 servers. 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, the processor has four, six, or eight UltraSPARC
cores. Each core equates to a 64-bit execution pipeline capable of running eight
threads. The result is that the 8-core processor handles up to 64 active threads
concurrently.
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.

Support for Virtualization Through Logical Domains (LDoms)
The SPARC Enterprise T5120 and T5220 servers support 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.
10 SPARC Enterprise T5120 and T5220 Servers Overview Guide • July 2009
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:
■ Kernel, patches, and tuning parameters
■ User accounts and administrators
■ Network interfaces, MAC addresses, and IP addresses
Each logical domain can interact only with those server resources made available to
it. The configuration is controlled using the Logical Domains Manager.

Remote Manageability With ILOM
The Integrated Lights Out Manager (ILOM) feature is a service processor that is built
into the server, and 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 that you can use 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 SPARC Enterprise T5120 and
T5220 server conditions:
Understanding Server Features 11
■ CPU temperature conditions
■ Hard drive status
■ Enclosure thermal conditions
■ Fan speed and status
■ Power supply status
■ Voltage conditions
■ Solaris watchdog, boot time-outs, and automatic server restart events
In addition to the ILOM CLI and browser interface, you can set up the server to use
the ALOM CMT compatibility CLI. The ALOM CMT compatibility CLI provides
commands that approximate the ALOM CMT UI that was provided on some
previous servers.

High Levels of 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 SPARC
Enterprise T5120 and T5220 servers offer the following features:
■ Ability to disable individual threads and cores without rebooting
■ Lower heat generation, reducing hardware failures
■ Hot-pluggable hard drives
■ Redundant, hot-swappable power supplies (two)
■ Redundant N+1 hot-swappable fan modules
■ Environmental monitoring

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.

Environmental Monitoring
The SPARC Enterprise T5120 and T5220 servers feature an environmental monitoring
subsystem that protects the server and its components against:
■ Extreme temperatures
■ Lack of adequate airflow through the system
■ Power supply failures
■ Hardware faults
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 panels. 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 service processor, backup sensors protect the system from serious damage, by
initiating a forced hardware shutdown. The 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.

Fault Management and Predictive Self Healing
The SPARC Enterprise T5120 and T5220 servers provide 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 SPARC Enterprise T5120 and T5220
servers.
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.
