Executive Summary
Executive Summary
In recent years, emerging applications and expanding web services have fueled an
escalating demand for mission-critical IT resources, with increasing numbers of
collaborative business initiatives focused on information sharing and continuous data
availability. As a result, IT data centers experienced rapid growth as the number of
applications, the population of users, and the quantity of transactions multiplied.
Today IT managers face the task of administering a complex storage and computing
infrastructure — one that typically contains many small servers added over time to
meet ongoing resource demands. Since administrative, energy, and real estate costs
continue to skyrocket, data center sprawl can severely strain IT budgets. To curb
operational expenses, many companies are turning to consolidation and virtualization
to improve resource utilization and enhance business agility.
Sun’s expertise in delivering mission-critical computing solutions and its focus on ecoresponsibility are evident in designs of a new platform family — the Sun Fire™ X4150,
X4250, and X4450 servers. Using high performance Intel® Xeon® processor technology,
Sun has engineered powerful 1U and 2U systems that are ideal for HPC, grid
computing, database, web infrastructure, and consolidation and virtualization
initiatives. These systems offer breakthrough compute, memory, storage, and I/O
density. At the same time, they feature tremendous energy efficiency as well as flexible
support for multiple operating systems — the Solaris™ Operating System, Linux,
Windows, and VMware.
The Sun Fire X4150, X4250, and X4450 servers showcase Intel’s talent for creating highperformance commodity chip sets along with Sun’s innovative engineering and quality
system design. In addition to remarkable expandability and density (such as over 2
terabytes of internal storage or up to four six-core Intel Xeon processors in a single 2U
chassis), these servers feature several redundant and hot-swappable components,
efficient front-to-back air flow, highly efficient power supplies, and built-in system
management tools. Engineered for mission-critical application availability, the Sun Fire
X4150, X4250, and X4450 servers strive to conserve valuable energy resources and
lower operational expenses while delivering high performance and density in an
extremely small footprint.

Chapter 1
Managing Capacity and Complexity
In today’s competitive global marketplace, companies place ever-increasing demands
on the IT infrastructure for compute and storage resources. As a result, most
datacenters have grown exponentially in recent years, with large numbers of servers
and storage racks continuously added to satisfy business requirements and meet
escalating resource demands.
Such rapid growth has produced its own set of challenges. The cost of maintaining
large numbers of servers can prove to be formidable, especially at a time when real
estate costs are rising, energy costs are skyrocketing, and department budgets are flat
or declining. Managing the complexity that results from sprawling server resources
puts tremendous strain on IT staff and budgets. To successfully meet business needs,
IT management must control both cost and complexity while simultaneously scaling
processing and storage capacity.
Today the responsibility of managing datacenter capacity and rapid growth commonly
fuels IT initiatives like consolidation and virtualization. Typically, these initiatives strive
to improve resource utilization, reduce administrative complexity, and drive down IT
costs. Consolidating many small servers into fewer powerful systems helps to minimize
administrative workloads while increasing capacity and conserving valuable floor
space. It can also help to reduce energy costs, vastly improving available performance
relative to the amount of energy consumed. In addition, when IT organizations
consolidate under-utilized resources, virtualization technologies can balance IT
resource demands, applying key resources as needed to business-critical applications to
enhance agility.
Introducing the Sun Fire™ X4150, X4250, and X4450 Servers
To help IT managers address the challenge of increasing capacity while managing
growth, Sun offers new Intel® Xeon® processor-based systems — the Sun Fire X4150,
X4250, and X4450 servers. These systems feature high performance and unprecedented
density in energy-efficient and compact 1U and 2U form-factors. With capabilities that
complement the rest of the Sun server product line, the Sun Fire X4150, X4250, and
X4450 servers raise the bar for 32- and 64-bit enterprise-class computing. These
systems offer:
• Best-in-class performance. The Sun Fire X4150, X4250, and X4450 servers feature
dual-, quad-, and six-core Intel Xeon 5000 and 7000 Sequence processors. With large
integrated caches and high clock speeds, these processors offer high system
performance and throughput compared with systems based on earlier generation
Intel chipsets. In high-end configurations, Sun Fire X4150, X4250, and X4450 servers
can house multiple Intel Xeon processors — for example, the Sun Fire X4450 server
Sun Microsystems, Inc.

Managing Capacity and Complexity
supports up to four six-core Intel Xeon X7450 processors clocked at 2.66 GHz, for a
maximum of 24 cores and impressive performance in a compact 2U chassis.
• Remarkable density. Density is the cornerstone of the Sun Fire X4150, X4250, and
X4450 server designs. When populated in a 40-rack unit (RU) enclosure, the 1U Sun
Fire X4150 server facilitates a single rack with up to 320 cores, 680 DIMM slots, and
120 PCI Express (PCIe) slots. The 2U Sun Fire X4450 server enables a single rack with
up to 480 cores maximum. In addition, the Sun Fire X4250 server can house over 2
terabytes internally using sixteen 2.5-inch SAS drives (via a PCIe Host Bus Adapter) in
a single 2U chassis. The Sun Fire X4150, X4250, and X4450 servers provide the type of
density needed to achieve consolidation and virtualization efficiencies. Such density
facilitates the consolidation of many smaller servers, helping to conserve real estate,
lower energy expense, and reduce costly administrative talent. In addition, these
servers support multiple operating systems, which helps to simplify consolidation
efforts and diminish server sprawl.
• Extensive system expandability. The ability to expand a server over time reduces the
need for additional capital acquisitions and lowers application lifecycle costs. The
Sun Fire X4150 and X4250 servers feature two CPU sockets per system and 64GB of
memory (using 4-gigabyte FB-DIMMs), while the Sun Fire X4450 houses four sockets
and up to 128 gigabytes of memory. The Sun Fire X4150 and X4450 servers support a
maximum of 1 terabyte of internal storage, while the Sun Fire X4250 server allows
over 2 terabytes of internal storage. Four GigabitEthernet ports are standard on all
systems. Because of breakthrough system densities, these servers can scale to
support new users, more transactions, or new 32-bit or 64-bit applications, enhancing
longevity and increasing overall return on investment (ROI).
• Improved energy efficiency. Sun offers a portfolio of eco-responsible products and
computing solutions to address customer IT needs. In the Sun Fire X4150, X4250, and
X4450 servers, Intel Xeon processors incorporate new technologies that minimize
power use and enhance energy efficiency. The Intel® Core Microarchitecture
optimizes processor performance relative to the power consumed. Power
management capabilities limit power to unused execution units in each core, which
helps to reduce power and cooling requirements. High-efficiency power supplies in
the server chassis lessen overall power consumption. Variable speed fans, disk carrier
design, and front-to-back air flow in the chassis help to effectively cool the system
and maintain appropriate processor and system ambient temperatures.
• Enterprise-class high availability. The Sun Fire X4150, X4250, and X4450 servers are
designed with enterprise-class RAS (Reliability, Availability, and Serviceability)
features. To maximize uptime, systems include redundant hot-swappable fans and
can be configured with redundant hot-swappable power supplies. Using a Sun
StorageTek SAS RAID Host Bus Adapter (HBA), internal SAS disk drives can be
configured for RAID 0, 1, 1E, 10, 5, 5EE, 50, 6, and 60 —when mirroring is
implemented, drives are also hot-swappable. Four integrated GigabitEthernet ports

enhance network availability — without consuming a PCIe slot — and can be
implemented in failover configurations. On-board system management tools
encourage remote, proactive monitoring and intervention.
• Simplified system management. To support out-of-band management, the Sun Fire
X4150, X4250, and X4450 servers incorporate a service processor that features robust
“lights-out” management capabilities. This built-in, hardware-based functionality
allows administrators to monitor and manage systems remotely, allowing them to
take corrective action as necessary and minimize unplanned downtime.
The Sun Fire X4150, X4250, and X4450 servers combine best-in-class performance with
noteworthy compute, memory, and I/O capacities. As a result, these systems are
designed to scale up, scale out, and scale within, enabling deployment in a wide range
of application architectures:
• Scale-up architectures: With multiple cores, these servers are well-suited to scale for
growing workloads that deliver web, database, and other key infrastructure services.
• Scale-out architectures: With large memory capacities, internal storage, four
GigabitEthernet ports, and high-bandwidth PCIe expansion for high-speed system
interconnects (such as fiber channel and InfiniBand), these servers can scale to solve
complex computing problems demanding intensive computing power and
data bandwidth.
• Scale-within: With the ability to support Solaris 10 Virtualization and VMware, Sun
Fire X4150, X4250, and X4450 servers are ideal systems to host virtualization
technologies and consolidate multiple applications within a single
extensible platform.

A Choice of Operating Systems
To optimize flexibility and investment protection, Sun Fire X4150, X4250, and X4450
servers support a choice of operating systems, including:
• Solaris Operating System (OS)
• Linux operating systems (64-bit Red Hat or SuSE Linux)
• Microsoft Windows
• VMware ESX Server
Chapter 4 describes the OS releases supported as of this writing. Please see sun.com/
x64 for the latest information on supported operating systems and environments.
Chassis Design Innovations
Sun Fire X4150, X4250, and X4450 servers share common chassis design characteristics
with other Sun x64 and SPARC® server platforms. This approach not only provides a
consistent look and feel across the product line, but simplifies administration through
consistent placement and shared components. Beyond consistency, this approach
provides a design focus that places key technology where it can make a difference in
the datacenter.
• Enhanced System and Component Serviceability
Finding and identifying servers and components in a modern datacenter can be a
challenge. Sun Fire X4150, X4250, and X4450 servers are optimized for lights-out
datacenter configurations with easy to identify servers and modules. Color-coded
operator panels provide easy-to-understand diagnostics and systems are designed for
deployment in hot-isle/cold-isle multi-racked deployments, with both front and rear
diagnostic LEDs to pinpoint faulty components. “Fault Remind” features help to identify
failed components.
Consistent connector layouts for power, networking, and management make moving
between Sun systems straightforward. All hot-plug components are tool-less and easily
available for serviceability. For instance, an integral hinged lid provides access to dual
fan modules so that fans can be serviced without exposing sensitive components or
causing unnecessary downtime.
• Robust Chassis, Component, and Subassembly Design
Sun’s volume servers share chassis designs that are carefully engineered to provide
reliability and cool operation. Even features such as the honeycomb-shaped chassis
ventilation holes help to provide the best compromise for strength, maximum airflow,
and maximum electronic attenuation. Next-generation hard disk drive carriers enhance
chassis ventilation, enabling greater storage density while increasing system airflow.
A removable disk cage in each system plugs directly in front of the fan tray assemblies,
allowing airflow to be directed both above and below disk drives, and above and below
memory FB-DIMMs and mezzanine boards to efficiently cool the system. Dual cooling

fan modules are isolated from the chassis to avoid transferring rotational vibration to
other system components. Also, the integration of the fan power board into the Fan
Tray assembly protects users from electrical shock during fan removal or insertion.
In spite of extreme computational, I/O, and storage density, Sun servers are able to
maintain adequate cooling using conventional technologies. Efficient modular fan
assemblies keep the chassis within an effective operating temperature range.
Minimized DC-to-DC power conversions also contribute to overall system efficiency. By
providing 12 volt power to the motherboard, power conversion stages are eliminated.
This approach reduces generated heat, and introduces further efficiencies to
the system.
• Minimized Cabling for Maximized Airflow
To minimize cabling and increase reliability, a variety of smaller boards and riser cards
are used:
– Power distribution boards (PDBs) distribute system power from the dual power
supplies to the motherboard and to the disk backplane (via a connector board).
– Connector boards eliminate the need for many discrete cables, providing a direct
card plug-in interconnect to distribute control and most data signals to the disk
backplane, fan boards, and the PDB.
– Fan boards provide connections for power and control for both the primary and
secondary fans in the front of the chassis. No cables are required since every
dual fan module plugs directly into one of these PCBs which, in turn, plug into
the Connector board.
– PCIe riser cards plug directly into the motherboard, allowing PCIe cards to be
easily installed.
– The disk backplane mounts to the disk cages in the enclosure, delivering disk
data through one or two 4-channel discrete mini-SAS cables from the installed
HBA card. An 8-disk backplane is offered for the Sun Fire X4150 and X4450 servers
while the Sun Fire X4250 server supports a 16-disk backplane. Also provided via
the disk backplane are two USB connections to the front of the system.

X4450 servers.

The Intel Advantage
Sun Microsystems, Inc. and Intel Corporation are collaborating in an alliance targeted
at building a comprehensive family of servers based on Intel® Xeon® processors and at
optimizing performance for the Solaris Operating System (OS). With the Intel processorbased Sun Fire X4150, X4250, and X4450 servers, Sun extends its existing X64 system
portfolio and complements its powerhouse SPARC® processor-based platforms. Moving
forward, Sun and Intel continue to participate in joint engineering efforts aimed at
enhancing the Solaris OS, Java™ technologies, and systems built using Intel Xeon
processor designs.
In this new family of servers, Sun’s well-known engineering expertise combines with an
emphasis on performance, quality, reliability, and eco-responsibility. The Sun Fire
X4150, X4250, and X4450 servers leverage dual-, quad-, or six- core Intel Xeon
processors that feature key Intel technologies for virtualization, I/O acceleration, and
energy efficiency. These 64-bit processors are compatible with the legacy of IA-32
software, instantly making available a large volume of existing 32-bit applications as
well as emerging 64-bit applications.
Figure 2. 50W Quad-core Intel Xeon L5420 Processor.
This chapter introduces the Intel Xeon processors and chipsets used in these new Sun
models. The Sun Fire X4150 and X4250 servers have two processor sockets that can be
populated with either dual- or quad-core Intel Xeon Processor 5000 Series for a
maximum of 8 cores. In contrast, the Sun Fire X4450 server contains four processor
sockets — supporting up to four dual-, quad-, or six-core Intel Xeon Processor 7000
Series, for a maximum of 24 cores in a single 2U chassis. The related system chipsets
include a Northbridge Memory Controller Hub (MCH) and a Southbridge Input/Output
Hub (IOH). For an overview of Intel chipsets used in these Sun servers, see Chapter 3.

The Intel Advantage
Multi-Chip Packaging
The Intel Xeon Processor 5000 Sequence processors use a Multi-Chip Package (MCP) to
deliver dual- and quad-core configurations, while the design of the Intel Xeon Processor
7000 Sequence enables dual-, quad-, and six- core configurations. The processor
packaging approach increases yields and lowers manufacturing costs, helping Intel and
Sun to deliver higher performance and throughput at lower price points.
Intel Xeon Processor 5200 and 5400 Series
Based on the Intel Core Microarchitecture, the Intel Xeon Processor 5200 and 5400
Series employ a second-generation 45nm manufacturing process that incorporates
smaller transistors, allowing the processors to consume less power, to achieve faster
switching times, and to provide greater density. (Earlier generation 5100 and 5300
processors used a 65nm manufacturing process.) The Intel Xeon 5200 and 5400 Series
processors feature microarchitecture enhancements, including larger Level-2 caches, in
comparison with earlier generation processors.
The Intel Xeon Processor 5200 and 5400 Series processors provide performance for
multiple application types and user environments in a substantially low power
envelope. The dual-core 5200 Series processors provide significant performance
headroom for multithreaded applications and can boost system utilization through
virtualization and application responsiveness. The quad-core 5400 Series processors
maximize performance-per-watt, providing increased density for datacenter
deployments where energy efficiency is a key goal.
Figure 3 shows logical diagrams for the 5000 Sequence. The 5200 Series processors
include dual execution cores, each with a 64K Level-1 cache (32K instruction/32K data).
The dual cores share a Level-2 cache (6 MB on the 5200 Series) to increase cache-toprocessor data transfers, maximize memory-to-processor bandwidth, and reduce
latency. The 5400 Series processors provide four execution cores. Each pair of cores
shares a 6 MB Level-2 cache, for a total of 12 MB. With two sockets in Sun Fire X4150 or
X4250 servers, 5400 Series processor designs enable a maximum of 8 processor cores in
a single 1U or 2U form factor.

Intel Xeon Processor 7200 and 7400 Series
In Sun Fire X4450 servers, the dual-core Intel Xeon Processor 7200 Series processor
incorporates two die per processor package, with each die containing a single
processor core (Figure 4). The Intel Xeon Processor 7400 Series is a monolithic design
that supports up to six cores. In a Sun Fire X4450 server configuration with four Intel
Xeon 7400 Series processors, this enables a maximum density of 24 execution cores in a
compact 2U enclosure.
Figure 4. Intel Xeon 7200 Series uses two die per package while the Intel Xeon
7400 Series is a monolithic design supporting up to six cores
The 5000 and 7000 Sequence processor families share these additional features:
• An integrated Level-1 (L1) instruction and data cache (64KB per core)
• Large integrated Level-2 (L2) cache. The Intel Xeon 7400 Series processors also feature
up to 16 MB of shared Level 3 cache.
• Multiple, independent Front Side Buses (FSBs) that act as high-bandwidth system
interconnects. The Intel Xeon 5000 Sequence processors support both 1066 MT/sec
and 1333 MT/sec Front Side Buses enabling theoretical data transfer rates of 8.66
GB/sec (at 1066 MT/sec) or 10.5 GB/sec (at 1333 MT/sec). The 7000 Sequence
supports Front Side Bus interconnects at 1066 MT/sec.
Like the Intel Xeon Processor 5200 and 5400 Series, the 7400 Series processors use a
new, second-generation 45nm manufacturing process along with an enhanced
microarchitecture. (Earlier generation 7300 processors used a 65nm manufacturing
process.) The 45nm manufacturing process leverages the use of smaller transistors,
enabling higher densities, lower power consumption, and faster switching times.
Microarchitecture enhancements support up to six cores, large Level-2 caches, and a
shared Level-3 cache of up to 16 MB. As a result, 7400 Series processors offer fast
performance and innovative features that are ideal for addressing server consolidation
and virtualization initiatives.

• Out-of-order execution conserves processor-to-memory bandwidth, improving
memory access and increasing overall processing performance
• Speculative prefetches move data to the L2 cache before an L1 cache request occurs
• Large L2 caches (6 MB on dual-core 5200 Series, 12 MB on quad-core 5400 Series,
8 MB on dual-core 7200 Series, 6 MB on quad-core 7400 Series, and 9 MB on six-core
7400 Series) help to increase system memory efficiency and enhance performance.
On the Intel Xeon 7400 Series, up to 16 MB of shared Level-3 cache can enable ready
access to the working set for performance-critical applications.
• Power management capabilities modulate power delivery to execution cores,
limiting power to unused components
These features help to enhance performance and conserve processor power, which can
translate into energy savings and lower operational costs. Table 2 and Table 3 list
typical power envelopes for Intel Xeon processors that are configurable in the Sun Fire
X4150, X4250, and X4450 servers as of this writing. Additional processor characteristics
are also included.

System Processors and Chipsets
Although the Sun Fire X4150, X4250, and X4450 servers are based on different Intel
Xeon processors and associated chipsets, they share a similar system-level architecture.
In these systems, multiple host processors interface to the Northbridge MCH over
multiple Front-Side Buses (FSBs) — two FSBs in the Sun Fire X4150 and X4250 servers
and four in the Sun Fire X4450 server. The Southbridge IOH interfaces to the I/O
devices, enabling expandability along with high I/O throughput. Each chipset is
designed to match processor performance with memory capacity, I/O expandability,
and interconnect bandwidth.
Intel Xeon 5000 Sequence Chipset
Refer back to the Sun Fire X4150 and X4250 server block diagrams earlier in this
chapter. The Sun Fire X4150 and X4250 servers incorporate the Intel Xeon Processor
5000 Sequence chipsets, which consist of:
• One or two dual-core Intel Xeon 5200 Series processors or quad-core Intel Xeon 5400
Series processors
• The Northbridge Intel 5000P Memory Controller Hub (MCH)
• The Southbridge Intel 6321ESB Input/Output Handler IOH (ESB-2). The ESB-2 is
interconnected to the MCH using one ESI (Enterprise South Bridge Interface) link and
one PCIe link. ESI is based on x4 PCIe interconnect with proprietary extensions and
offers a 2 GB/sec transfer rate.
Dual independent Front Side Buses (FSBs) act as a system interconnect between each
processor socket and the MCH. Operating at either 1066 MT/sec or 1333 MT/sec, the
64-bit wide FSBs are capable of peak bandwidths up to 8.5 GB/sec or 10.5 GB/sec
respectively. For more information on the Intel Xeon Processor 5000 Sequence chipset,
see www.intel.com/products/processor/xeon5000/.
Sun Microsystems, Inc.

22
Intel Xeon 7000 Sequence Chipset
Refer back to the Sun Fire X4450 server block diagrams (earlier in this chapter). The Sun
Fire X4450 server uses an Intel Xeon Processor 7000 Sequence chipset, which includes:
• Up to four dual-core Intel Xeon 7200 Series processors, or up to four quad- or six-core
Intel Xeon 7400 Series processors
• The Northbridge Intel 7000P Memory Controller Hub (MCH)
• The Southbridge Intel 6321ESB Input/Output Handler IOH (ESB-2)
With the 7000 Sequence chipset, four FSB buses connect between the four processor
sockets and the MCH. Running at 1066 MT/sec, the 64-bit wide FSBs are capable of
peak bandwidths of 8.5 GB/sec each. For more information on the Intel Xeon Processor
7000 Sequence chipset, see www.intel.com/products/processor/xeon7000/.
Memory Subsystem
To address memory-intensive applications, multiple FB-DIMM memory channels help to
support large memory densities and high bandwidth in the Sun Fire X4150, X4250, and
X4450 servers. The memory subsystems are based on similar Intel MCH controller
designs that feature four independent memory channels.
In the Sun Fire X4150 and X4250 servers, each memory channel supports up to four FBDIMMs, enabling up to 16 FB-DIMMs per system for a maximum capacity of 64GB using
4GB modules. In the Sun Fire X4450 server, each channel supports up to eight memory
modules for up to 32 FB-DIMMs per system, allowing a memory capacity of up to 128GB
in the 2U chassis using 4GB FB-DIMMs. In all systems, the four memory channels are
organized into two branches. Modules of identical size must be populated in pairs,
starting with memory slot 0 on each channel (slot 0 on each channel is marked with
white handles).
The same 667 MHz, PC2-5300 DDR2 FB-DIMM modules — in either 1 GB, 2 GB, or 4 GB
capacities — are supported in the three server models. Peak read bandwidth to the FBDIMMs is 5.3 GB/sec per channel (21 GB/sec total with the 1333 MT/sec system bus),
and peak write bandwidth is 2.7 GB/sec per channel (10.7 GB/sec total with the 1333
MT/sec system bus). Memory modules feature Error Checking and Correcting (ECC)
with Chipkill technology for high reliability.

Sun Fire X4150, X4250, and X4450 Server Architectures
I/O Subsystem
Designed for the headroom needed to expand systems and scale applications, the Sun
Fire X4150, X4250, and X4450 servers feature a PCIe expansion bus, integrated storage,
four on-board Intel Gigabit Network Interface Controllers (NICs), and five USB ports.
The same Southbridge ESB-2 chip is used on the three server models. In each case, it is
interconnected to each system’s Northbridge MCH using one ESI link and one PCIe link.
The ESB-2 provides two built-in GigabitEthernet NICs going to external NIC ports 0
and 1. Two additional GigabitEthernet NICs (port 2 and 3) are connected to a Dual
Gigabit Intel Ophir 82571 chip that interfaces to the ESB-2 using a 4-lane PCIe link. The
ESB-2 also supports all USB functionality — two USB ports go from the ESB-2 to the rear
of the system, one is routed to an internal USB hub for the two front USB connections,
and one USB port is inside the chassis for internal boot devices.
The ESB-2 also supports a USB-to-IDE interface that enables the connection of an
optional internal EIDE DVD/RW drive, and connects to the service processor via a
32-bit, 33MHz PCI channel.
System Network Interfaces
Multiple on-board GigabitEthernet connections promote flexible connectivity, as well
as configurations that support network interface failover. Each server features four
10/100/1000 Mbit/sec Ethernet ports on the rear panel, numbered in sequence from
left to right. Each port auto-negotiates its link connection, and LEDs above the port
indicate the speed of the established link (green signifies that the established link is
1000 Mbit/sec). All four Ethernet interfaces support PXE boot for network
interface booting.
PCIe Expansion Bus
The Sun Fire X4150, X4250, and X4450 servers include a PCIe expansion bus that
accommodates 64-bit low-profile cards. On each server model, three right-angle risers
plug directly into the motherboard to enable PCI expansion (Figure 11). On the Sun Fire
X4150 server, the risers support one slot per riser, for a total of three internal 8-lane
PCIe slots (all with x16 mechanical connectors). In contrast, on the Sun Fire X4250 and
X4450 server, each riser supports two PCIe card slots. On the Sun Fire X4250 server,
each riser provides two 8-lane (electrical and mechanical) slots, for a total of six x8 slots
in the 2U chassis. On the Sun Fire X4450 server, each riser supports two card slots with
one x8 and one x16 mechanical connector, also for a total of six slots in a
2U chassis.

Of note, the three PCIe risers for the Sun Fire X4250 server are “active” riser cards —
that is, a IDT PES24N3A PCIe switch resides on the riser card (Figure 12). The PES24N3A
switch provides high-performance I/O connectivity and switching functions between a
x8 PCIe upstream port and two x8 downstream ports. It can operate either as a storeand-forward switch or as a cut-through switch (depending on packet size) and supports
switching of memory and I/O transactions. It supports eight Traffic Classes (TCs) and
one Virtual Channel (VC) with sophisticated resource management algorithms
(including round robin, weighted round-robin, and strict priority schemes). These
algorithms support sufficient bandwidth allocation and latency for critical traffic classes
in applications such as high throughput 10 Gigabit I/Os, SATA controllers, and Fibre
Channel HBAs.

5 are routed to the ESB-2 while Slots 0, 1, 3, and 4 connect to the MCH.
Slot 1 on the Sun Fire X4150 and X4250 servers is used for an optional host bus
adapter to support internal SAS disk drives. On the Sun Fire X4450 server, the
optional adapter is installed in Slot 0.
Integrated Storage
In addition to breakthrough compute, memory, and I/O densities, these servers offer
large internal storage capacities — up to 1TB in the Sun Fire X4150 and X4450 servers,
and up to 2TB in the Sun Fire X4250 server. The Sun Fire X4150 and X4450 servers can
support up to eight internal 2.5-inch SAS drives (via a PCIe Host Bus Adapter), while the
Sun Fire X4250 server can house a remarkable sixteen SAS drives internally. Either 73GB
10,000RPM or 15,000RPM, or 146GB 10,000RPM SAS drives are available.
The ample storage density of these servers is partly due to an innovative new drive
carrier design that incorporates honeycombed grillwork to facilitate effective air flow
above and below each drive. Drives insert into a modular disk tray and cable-free disk
backplane that increases reliability and serviceability. The carrier includes an ejection
handle that simplifies drive removal — drives are hot-swappable when disk mirroring is
configured. Drive status lights indicate “Ready to remove”, “Fault”, and “Status”.
In all three systems, the disks plug into a backplane board. In the Sun Fire X4250 server,
a 28-port LSI SAS expander (the LSISASX28) resides on the 16-disk backplane board to
enable this server’s large internal storage capacity. Eight ports on the SAS expander
connect to the SAS Host Bus Adapter, supporting switched connections to up to 16
SAS devices.
Disk Controller and I/O RAID Options
The Sun Fire X4150, X4250, and X4450 servers support these basic options for SAS disk
controllers:
• The Sun StorageTek SAS adapter, which supports hardware RAID 0, 1, or 1E. Based on
LSI 3081E technology, this controller is a low-profile card with two external 4-port
SAS connectors.
Sun Microsystems, Inc.
Sun Fire X4150, X4250, and X4450 Server Architectures
27
• The Sun StorageTek SAS RAID adapter, which supports 3 GB/sec SAS and hardware
RAID levels 0, 1, 1E, 5, 5EE, 6, 10, 50, and 60. Based on Adaptec technology, this
adapter is an 8-channel, low-profile card with two 4-port SAS connectors. This adapter
includes 256 MB of DDR2 memory on-board and a battery-backed write cache for 72hour backup, which helps to deliver protected, high availability storage.
To support SAS configurations, two cables with four lanes (each at 3 Gb/sec) each are
wired from the SAS adapter to the disk backplane to control the disk drives and provide
high bandwidth. In the case of the Sun Fire X4250 server, the four SAS links connect to
the LSISASX28 SAS expander on the 16-disk backplane. The SAS expander then provides
16 SAS links to the individual disks in the drive tray.
DVD/USB Assembly
A slim form-factor IDE optical drive assembly is also available as an option to the Sun
Fire X4150, X4250, and X4450 servers. The assembly provides an internal DVD-RW device
as well as two USB ports accessible from the front panel. A locking handle allows the
assembly to be safely secured and more easily extracted from the system chassis.
Systems can be ordered with an assembly that features two USB ports only (and no DVD
device), or with no DVD/USB option at all.
Enclosure Features
The Sun Fire X4150, X4250, and X4450 servers feature innovative chassis designs
engineered to conserve system power and reduce cooling. The power and cooling
efficiency of these systems exceeds that of many competitive systems configured with
similar processing, memory, and storage capacities. The effective front-to-back airflow
design helps to lower component temperatures, reducing the number of fans needed
to cool the system. Processors also consume less energy under cooler temperatures. In
addition, lower component temperatures help to increase reliability.
Key enclosure features include:
• Hex-shaped, honeycombed air inlet holes that enhance airflow and provide
EMI shielding
• Front-mounted fans (located directly behind the disk drive cage) that pull air through
the chassis, over system components, and exhaust it out the rear panel
• Innovative disk drive bracket design that enables efficient air flow above and below
drive units
• Cable and component placement that helps to optimize cooling efficiency by
channeling airflow effectively, as well as the reduction of internal cables to
enhance airflow
• Fewer DC-to-DC conversions to improve power efficiency and generate less heat

Power Distribution
Engineered for high availability as well as low energy consumption, the Sun Fire X4150,
X4250, and X4450 servers can be configured with two highly-efficient, redundant, hotswappable AC/DC power supply units (PSUs), each with separate power cords. The
PSUs differ between systems — the Sun Fire X4150 server uses 650W PSUs, the Sun Fire
X4250 server requires 1050W PSUs, and the Sun Fire X4450 server uses 1100W PSUs.
Configuring a system with a second power supply enables N+1 redundancy, supplying
continuous power to the system if a single power supply fails.
The power supplies are high-efficiency units, having a typical efficiency rating that
exceeds at least 80%. Each PSU features a non-removable internal fan that supplies
independent PSU cooling. Three light indicators display power supply status
information (“AC”, “Fault”, and “OK”).
The Sun Fire X4150, X4250, and X4450 servers use a Power Distribution Board (PDB) that
provides connections between the power supplies and major system components. The
PDB contains a single 10Amp 12V-to-5V DC-to-DC supply used to power the disk
subsystem and the optional IDE DVD-RW device.
Fan Assemblies
The server enclosures are designed for efficient front-to-back air flow. Variable speed
fans run under the control of the on-board Service Processor, which monitors processor
temperatures and system ambient air temperature. Based on these readings, the fans
operate at the lowest speeds possible to provide sufficient cooling — conserving power
usage, prolonging fan life, and reducing acoustical noise.
Fan assemblies differ between the Sun Fire X4150, X4250, and X4450 servers. The Sun
Fire X4150 server houses seven fan modules, with each module containing two 40mm,
10,000RPM fans. In the Sun Fire X4250 and X4450 servers, there are six fan modules,
with each module accommodating two hot-swappable 60mm fans.
A green status light on a fan module indicates proper operation while an amber light
indicates a fan fault. Fan modules on these systems are designed for redundancy — a
backup fan enables system continuity in the event of a fan failure. The fans are also hotswappable such that a module with a failed fan can be removed and a new fan module
inserted without shutting down the system.
Rack Mounting
To shorten time-to-deployment, the Sun Customer Ready Systems program can preinstall Sun Fire X4150, X4250, and X4450 servers in a rack configuration. Alternatively,
the 1U and 2U servers can be field-installed into Sun or other third-party racks.
The following options are available from Sun to facilitate rack mounting:
• Rack-Mounting Slide Rail Kit. This is a 4-point mounted slide rail kit (i.e., mounting
points are located at the rack front and rear).
Sun Microsystems, Inc.
Sun Fire X4150, X4250, and X4450 Server Architectures
29
• Tool-less Rack Kit. As the name implies, this rack-mounting kit snaps into most thirdparty racks without requiring any tools.
• Cable Management Arm. The Cable Management Arm supports and protects cables
as the server slides into and out of the rack.
The Slide Rail Kit and optional Cable Management Arm enable the servers to be
installed in these racks:
• Sun Rack 900 (-38 and -36N)
• Sun Rack 1000 (-38 and -42)
• Third Party ANSI/EIA-310-D-1992 or IEC 60927-compliant racks in 19-inch/482.6mm
panel-width series
The Slide Rail Kit includes hardware to mount to rack rails with either 6mm threaded
holes, #10-32 threaded holes, #10 clearance holes, or square unthreaded holes per
ANSI/EIA 310-D-1992 or IEC 60927 standards. Note that not all third-party racks are
compatible with the slide rail kit. Rack density will vary widely based on systems
installed, power distribution (in-cabinet or external), power source (single-phase or
three-phase), and whether redundant power is required.
Service Processor and System Management
Similar to other Sun servers, the Sun Fire X4150, X4250, and X4450 servers feature a
built-in, hardware-based service processor. Integrating the service processor on the
motherboard enables remote power control and system monitoring — capabilities that
help to simplify system management.
The Sun Fire X4150, X4250, and X4450 servers embed an Aspeed AST2000 chip as the onboard service processor. The Aspeed AST2000 combines a graphics controller and a
service processor into a single chip, saving space and power. It uses two USB ports for
virtual devices and one 32-bit, 33Mhz PCI bus for data to connect to the Southbridge
ESB-2 (refer back to system block diagrams earlier in this chapter).
For system management operations, the AST2000 supports three external interfaces on
the rear panel:
• one RJ45 RS-232 serial interface
• one 10/100 Mbit/sec Ethernet network interface (also an RJ-45 connector)
• one HD-15 SVGA video port
The serial interface is intended for console use only (it does not support modem
connection). Default serial port configuration parameters are 9600 baud, 8 data bits, no
parity, 1 stop bit, and no flow control. By default, the BIOS directs system output to the
Service Processor, or it can be redirected to the serial port by changing a BIOS option.
The BIOS can also be used to check or modify the Service Processor’s IP address.

Integrated System Management Capabilities
The need for high availability in business-critical systems calls for robust and proactive
system management. The AST2000 service processor supports firmware-resident system
management capabilities that enable remote monitoring and system control using
industry-standard protocols. Since system management tools reside in firmware, they
can be easily upgraded and enhanced at a future time.
The AST2000 service processor and system management tools are IPMI 2.0 compliant.
The service processor enables management functionality that includes: system
configuration information retrieval; key hardware component monitoring; remote
power control; full local and remote keyboard/video/mouse (KVM) access; remote
media attachment; SNMP V1, V2c, and V3 support, and event notification and logging.
Digital thermal sensors on the processor and the motherboard are used to monitor
temperatures, which helps to increase reliability. The service processor continuously
monitors and detects errors on these and other system sensors:
• Memory Voltage
• CPU Core Voltage
• System 3.3V
• System 5V
• System 12V
• CPU Fan
• System Fans
• CPU Temperature
• Chassis Temperature
Administrators can track status information from these sensors and take action before
a minor system issue escalates into a serious problem.
Secure access to the service processor and its management capabilities is available in
several ways:
• Via a Secure Shell (SSH) command line interface. To access management capabilities
through a remote Secure Shell (SSH), a Secure Shell communications application
must be available on the remote administrative system.
• Using a Command Line Interface (CLI) with industry-standard keyboard commands
and scripting protocols. The Desktop Management Task Force’s (DMTF) Systems
Management Architecture for Server Hardware (SMASH) command line protocol is
supported over both the serial interface and the secure shell network interface.
• Via Simple Network Management Protocol (SNMP) v3 interfaces for external
datacenter management tools (such as Sun N1™ System Manager, IBM Tivoli®, and
Hewlett-Packard OpenView®).
• Using an easy-to-use, web-based graphical user interface. The web-based interface
offers a wide spectrum of management capabilities, from retrieving current system
configuration data to monitoring the status of key hardware components.
Sun Microsystems, Inc.
Sun Fire X4150, X4250, and X4450 Server Architectures
31
• Redirecting the managed server’s console to a Remote Console application. The
Remote Console application is a piece of layered software that allows remote clients
to view the graphical console as though clients were directly attached to the
managed server’s video connector. Remote Console allows the remote keyboard,
mouse, CD-ROM drive, or floppy drive to be configured to appear as standard USB
devices. The Remote Console application is embedded in the service processor,
minimizing the need for software installation on remote administrative workstations.
For enhanced security, the service processor includes multi-level role-based access, and
supports native and Active Directory Service lookup of authentication data. All functions
can be provided out-of-band through a designated serial or network interface, virtually
eliminating any performance impact to workload processing.
Keyboard/Video/Mouse Over IP
To simplify remote access to management functions, the service processor supports
Keyboard/Video/Mouse (KVM) over IP to redirect the server’s video screen, keyboard,
and mouse data to a remote administrative workstation via the network.
Administrators can access the KVM-over-IP function in the Java technology-based
Remote Console application by using a standard web browser and SSL authentication.
The service processor captures keyboard and mouse input and output at the remote
workstation and emulates USB-connected keyboard and mouse devices. The Sun Fire
X4150, X4250, and X4450 servers then detect these emulated devices and treat them as
directly connected interfaces. The service processor captures, compresses, encrypts,
and sends the video output to the remote workstation. The workstation subsequently
receives and displays the managed server’s video screen. Advanced Encryption
Standard (AES) governs encryption and decryption of KVM control commands to protect
the managed server from intervention by a remote hacker.
Virtual Storage
The virtual storage feature of the service processor emulates devices to enable remote
storage operations — just as if the units were physically attached to the Sun Fire
X4150, X4250, or X4450 server. The service processor incorporates a USB 2.0 device
controller that connects to the server’s internal USB host controller. By using the
Remote Console application to launch the virtual storage function at a remote
workstation, the server detects USB storage device attachment.
Sun Microsystems, Inc.
Sun Fire X4150, X4250, and X4450 Server Architectures
32
This feature applies to a variety of remote storage devices such as DVD, CD-ROM, and
floppy drives, as well as USB flash disk drives and ISO image files. For example, when
CD-ROM emulation is enabled, the Sun Fire X4150, X4250, and X4450 servers detect a
USB-attached CD-ROM. A target disk placed in the CD-ROM drive of the remote PC
becomes accessible by the managed server. To maintain security, the Advanced
Encryption Standard governs remote storage transmissions. In addition, administrators
can use KVM over IP and virtual storage together to enable remote booting, or to
remotely install operating systems, device drivers, or application software.
In-band System Management
Some organizations prefer in-band system management in order to standardize
administrative tasks across multi-vendor, heterogeneous environments. Using in-band
system management, administrators perform monitoring and maintenance tasks
through the host operating system. The Sun Fire X4150, X4250, and X4450 servers
provide in-band system management using two methods: IPMI v2.0 with a Keyboard
Controller Style interface and IPMI kernel driver, or by using SNMP operating system
resident agents. IPMI 2.0 and SNMP V1, V2c, and V3 are industry-supported standards
for performing autonomous platform management functions.
RAS Features
Corporate data and business information comprise critical business assets. Enterprise
computing technologies strive to furnish a high degree of data protection (reliability),
to provide virtually continuous application access (availability), and to incorporate
procedures and components that help to resolve problems with minimal business
impact (serviceability). Commonly referred to as RAS, these capabilities are a standard
part of Sun’s mission-critical computing solutions.
The Sun Fire X4150, X4250, and X4450 servers are engineered for hardware failure
prevention, near continuous operation, fast recovery, and easy serviceability. RAS
features for these systems include:
• High CPU density. Multiple Intel Xeon processors in 1U and 2U form factors enable
density that increases overall availability.
• Hot-swappable redundant components. Mirrored disks, redundant fan modules, and
redundant power supply units can be quickly and easily changed out, increasing
system uptime.
• Accessible components for improved serviceability. Front-accessible, hot-swappable
disk drives can be replaced quickly. The optional DVD/RW drive can also be removed
without opening the top cover of the chassis. Fan modules and power supply units
can be replaced without completely removing a system from the rack.
Sun Microsystems, Inc.
Sun Fire X4150, X4250, and X4450 Server Architectures
33
• A variety of RAID options, allowing customers to balance storage capacity,
availability, and cost. The LSI-based SAS controller supports RAID 0, 1, and 0+1, while
the Sun StorageTek SAS RAID host bus adapter supports RAID 0, 1, 10, 1E, 5, 50, 5EE,
6, 60 and also features battery backup of disk writes.
• Indicator LEDs on the front and back of the chassis. Easily visible LEDs allow problems
to be identified and isolated easily. Diagnostic LEDs are also included on
the motherboard.
• Integrated lights-out management capabilities. Standard on the Sun Fire X4150,
X4250, and X4450 servers at no additional charge, the integrated service processor
provides powerful tools for local or remote system management, simplifying
administrative tasks, reducing on-site personnel needed, and lowering overall
operational costs.

environments. Sun’s support for multiple operating systems enables organizations to
deploy a choice of application environments without having to shift hardware
platforms when software requirements change. This added flexibility enables
enterprises to reduce cost and complexity when supporting and managing solutions
from multiple vendors, helping organizations to reduce risk and increase return
on investment.
The Sun Fire X4150, X4250, and X4450 servers are certified to run the following
operating system versions (subsequent releases of these operating systems are also
expected to be supported and Sun-qualified):
• Solaris 10 8/07 Operating System
• Red Hat Enterprise Linux 4 Update 5 (32-bit or 64-bit) or Red Hat Enterprise Linux 5
(32-bit or 64-bit)
• SUSE Linux Enterprise Server 10 SP1 (64-bit)
• VMware ESX 3.0.2
• Windows Server 2003, Standard and Enterprise Editions (32-bit or 64-bit)
Additional patches and drivers required to complete the installation of these operating
systems are available from the web site sun.com/download/ or on the Tools and
Drivers CD-ROM provided with every Sun Fire X4150, X4250, and X4450 server. The
drivers and installation scripts on the Tools and Drivers CD-ROM help to reduce the
complexity of installing supported operating system distributions (since additional
device drivers are included on the CD-ROM). Note that the Solaris 10 OS, Red Hat
Enterprise Linux 5, SUSE Linux Enterprise Server 9, Windows Server 2003, and VMware
ESX are available directly from Sun along with support contracts. In addition, the Sun
Fire X4150, X4250, and X4450 servers come with the Solaris 10 OS pre-installed, or can
be ordered with Windows 2003 Server pre-installed.
The Solaris™ Operating System
In a class by itself, the Solaris 10 OS offers many innovative technologies that change
the equation for organizations needing to reduce costs, minimize complexity, and
eliminate risk. Optimized for Sun Fire systems with 64-bit Intel Xeon processors and
supported on hundreds of third-party x86 and x64 systems, the Solaris 10 OS brings
flexibility and power to the enterprise. Running on diverse hardware, ranging from

supports demanding applications that include military command and control systems,
telecommunication switch gear, and stock trading applications, among others.
Provided on all Sun systems at no charge, the Solaris OS delivers performance, security,
scalability, and reliability advantages for scale-out computing environments.
Underlying technologies (such as a high performance networking stack, advanced file
system, and modern memory model) combine to optimize performance of hosted
applications. A suite of security features previously only found in Sun’s military-grade
Trusted Solaris™ operating system are now included to fortify the commercial
enterprise. The Solaris OS supports near linear scalability from 1 to 72 CPUs and
addressability of up to 264 bytes of memory, well beyond the physical memory limits of
even Sun’s largest server. In addition, by providing the ability to automatically recover
from hardware faults, the Solaris OS enables maximum data and
application availability.
One of the most advanced operating systems on the planet, the Solaris OS includes
features not found in any other operating system, including:
• Solaris Dynamic Tracing (DTrace) is a powerful tool that provides a true, system-level
view of application and kernel activities, even those running in a Java Virtual
Machine. System administrators, integrators, and developers can use this dynamic
instrumentation tool to reduce the time to diagnose problems from days and weeks
to minutes and hours, accelerating problem resolution.
• Solaris Containers technology provides a break-through approach to virtualization
and software partitioning, supporting the creation of many private execution
environments within a single instance of the Solaris OS. Using this technology,
organizations can improve resource utilization, reduce downtime, and lower
solution costs.
• Predictive Self Healing technology automatically diagnoses, isolates, and recovers
from many hardware and application faults. As a result, business-critical applications
and essential system services can often continue uninterrupted in the event of
software failures, major hardware component breakdowns, and software
misconfiguration problems.
• Resource management facilities built into the Solaris 10 OS enable computing
resources to be allocated among individual tasks and users in a structured, policydriven fashion. By using these facilities to proactively allocate, control, and monitor
system resources (such as CPU time, processes, virtual memory, connect time, or
logins) on a fine-grained basis, organizations can often reach and maintain more
predictable service levels.
