Your challenge is to do more with less—serve more Web pages, handle more secure
connections, support more e-mail users—all while reducing costs and saving space. The dual®
™
socket IBM System x3550, incorporating IBM X-Architecture features, meets that challenge.
®
™
It supports the latest quad- and dual-core Intel Xeon processors (including 50W low-voltage
quad-core Xeon processors), designed with up to a leading-edge 1333MHz front-side bus (FSB),
64-bit extensions (EM64T), and either 6MB or 4MB (dual-core) or 8MB or 12MB (quad-core) of
L2 cache, to help provide you with the computing power you need to match your business needs
and growth. In addition, the x3550 uses industry-standard fully buffered 667MHz memory with
™
Chipkill ECC (Error Checking and Correcting) protection—for high performance and reliability.
For even higher levels of availability, the x3550 also offers a choice of optional online hot-spare
memory or memory mirroring. Dual integrated high-speed Gigabit Ethernet controllers with TOE
(TCP Offload Engine) and Jumbo Frame support are standard, as are high-performance adapter
slots (PCI-E x8 and optional PCI-X/133).
All models offer impressive scalability, including dual-processor support, up to 32GB of memory
and a choice of high-performance hard disk drives with an internal storage capacity of 600GB
(two 3.5-inch hot-swap Serial-Attached SCSI), 587.2GB (four 2.5-inch hot-swap SAS) or
2TB (two 3.5-inch simple-swap Serial ATA II). The integrated SAS controller provides
hardware-based RAID-0/1/10 standard for SAS drives. (SATA models offer firmware-based RAID
™
0/1 support standard.) Additional RAID support is available via the optional IBM ServeRAID
family of SAS and SATA controllers. The ultradense 1U form factor allows businesses to increase
their computing power and spread their workload without outgrowing their current data center. Up
to 42 of these 1U servers can be installed in a single 42U rack, for a total of up to 84 processors,
offering tremendous deployment flexibility. Optional Advanced Connectivity Technology (ACT)
interconnect cabling reduces cable clutter and cost and minimizes installation time when
interconnecting many rack-mounted servers.
Standard in the x3550 is an integrated Baseboard Management Controller (BMC) that enables
the user to manage and control the server easily—both locally and remotely. This high level of
manageability is designed to keep costs down and the system up—even when network usage
increases. The drop-down light path diagnostics panel enables quick servicing of the system if
a problem develops. These advanced features help maximize network availability by increasing
uptime, as do simple-swap SATA HDDs; hot-swap/redundant SAS HDDs, power and fans;
™
Active Memory ; integrated RAID; temperature-controlled fans with Calibrated Vectored
™
Cooling ; IPMI 2.0 support, including highly secure remote power control and Serial over
LAN; as well as text-console redirect over LAN.
With the inclusion of unique IBM service and support features such as the BMC, light path
diagnostics, IBM Systems Director, IBM Systems Director Active Energy Manager for x86
™
(formerly known as PowerExecutive), IBM ServerGuide and support for the optional slotless
Remote Supervisor Adapter II SlimLine, the x3550 is designed for superior uptime.
If you need highly manageable, dual-socket/multi-core computing power in a rack-dense
package, the x3550 is the ideal system.

superior performance capable of tackling the toughest jobs. 64-bit extensions provide the
flexibility to run 32-bit and 64-bit applications concurrently.
• Low-voltage processors draw less energy and produce less waste heat than high-voltage
processors, thus helping to reduce data center energy costs. Some dual-core Xeon
processors use only 65W. This is half the wattage consumed by older 130W processors. The
50W and 80W quad-core processors are even more economical, consuming only 12.5W and
20W (respectively) per core, vs. 32.5W per core for the 65W dual-core processors.

• Ultra-fast fully buffered 667MHz PC2-5300 DDR II ECC memory with Chipkill protection
provides speed and high availability.
• Two high-speed PCI-E adapter slots offer investment protection by supporting highperformance adapters, such as 10Gb Ethernet, Fibre Channel and InfiniBand cards, none of
which will run in older 33MHz and 66MHz conventional PCI slots.
• Integrated ServeRAID-8k-l provides RAID-0/1/10 support at no extra charge and without
consuming a valuable adapter slot. RAID-0 offers improved disk performance via data striping;
RAID-1 offers disk mirroring for high availability, and RAID-10 combines the benefits of speed
and availability. The x3550 is upgradeable to full RAID-0/1/10/1E/5/6 support, using the
optional ServeRAID-8k card. It also offers higher performance, due to the 256MB batterybacked onboard cache.
• Up to two 3.5-inch or four 2.5-inch (depending on the model) hot-swap SAS hard disk
drives offer high-performance with high availability. The SAS controller provides full-duplex (2
x 300MBps) data transfers for SAS drives. For lower cost and high capacity, other models
support up to two simple-swap Serial ATA drives. The SATA II drives offer performance
nearly equal to that of Ultra320 SCSI (300MBps half-duplex vs. 320MBps half-duplex,
respectively). Alternatively, 2.5-inch drives consume approximately half the power of 3.5-inch
drives.
• The integrated dual Gigabit Ethernet controllers with IPMI 2.0 support provide high-speed
network communications. Jumbo Frames offer higher efficiency transfers for large data
packets.
• The TCP Offload Engine (TOE) feature offers higher performance for TCP/IP traffic, with less
overhead on the system processor.
• A high degree of device integration—including SAS or SATA, RAID, dual Gigabit Ethernet,
systems management and video controllers—lowers costs and frees up valuable adapter
slots.
Flexibility
The x3550 has the ability to grow with your application requirements, thanks to
• A choice of quad-core or dual-core processors with 1.86 to 3.33GHz clock rates, 1333MHz
or 1066MHz FSB, and 50W to 120W maximum power draw.
• Up to 32GB of high-speed fully-buffered DDR2 system memory.
• Two available high-performance PCI-E adapter slots in all models. Optionally, if desired, the
riser card containing one of the PCI-E slots can be exchanged for a riser containing a PCIX/133 adapter slot.
• Installing the slotless ServeRAID-8k option upgrades the integrated ServeRAID-8k-l
controller with 256MB of low-cost, battery-backed cache to enable even higher-performance
hardware RAID support, and allows the x3550 to offer six RAID levels: RAID-0, 1, 10, 1E, 5
™
and 6. The optional MegaRAID 8480 controller supports up to four IBM System Storage
EXP3000 expansion units containing up to 48 SAS HDDs and 14.4TB of external storage.
2
• The six USB 2.0 ports are up to 40X faster than older USB 1.1 ports. This provides speedy
access to external HDDs (non-arrayed), optical drives, tape drives, and other USB devices.
Two ports are on the front of the unit and four are on the back.
• A choice of up to two internal 3.5-inch hot-swap SAS or simple-swap SATA II HDDs or four
2.5-inch hot-swap SAS HDDs (depending on the model) offer a variety of storage options.
The 3.5-inch SAS models provide a maximum of 600GB of internal hot-swap storage. The
2.5-inch SAS models support up to 587.2GB of hot-swap SAS storage. The 3.5-inch SATA
models provide a maximum of 2TB of internal simple-swap storage.
• Alternatively, iSCSI or Fibre Channel-attached storage can be attached using IBM System
®
Storage or TotalStorage servers.

A highly available and expandable, rack-dense, 1U dual-socket SMP server, for application
serving in Web environments
Powerful systems management features simplify local and remote management of the x3550:
• The x3550 includes a Baseboard Management Controller (BMC) to monitor server
availability, perform Predictive Failure Analysis, etc., and trigger IBM Systems Director alerts.
The BMC enables service personnel to use sophisticated diagnostic tools, such as light path
diagnostics, to resolve problems quickly.
• Integrated IPMI 2.0 support alerts IBM Systems Director to anomalous environmental factors,
such as voltage and thermal conditions. It also supports highly secure remote power
control using data encryption.
• IBM Systems Director Active Energy Manager for x86, an IBM-exclusive, is designed to
take advantage of new system power management features, by providing power monitoring
and power capping features.
• Text Console Redirection support allows the administrator to remotely view x3550 text
messages over Serial or LAN.
• IBM Systems Director is included for proactive systems management and works with both
the blade’s internal BMC and the chassis’ management module. IBM Systems Director comes
with a portfolio of tools, including Management Processor Assistant, Rack Manager, RAID
Manager, Update Assistant and Software Distribution. In addition, IBM Systems Director offers
extended systems management tools for additional server management and increased
availability. When a problem is encountered, IBM Systems Director can issue administrator
alerts via e-mail, pager, and other methods.
• An optional Remote Supervisor Adapter II SlimLine provides additional systems
management capabilities, including Web-based out-of-band control; virtual floppy and optical
drive support; Windows “blue screen” error capture; LDAP and SSL support; and remote
redirection of PCI video, text, keyboard and mouse. And it does all this without consuming a
valuable adapter slot.
Availability and Serviceability
The x3550 provides many features to simplify serviceability and increase system uptime:
• x3550 servers use Chipkill-enabled fully buffered memory DIMMs. Chipkill memory is up to
16X better than standard ECC memory at correcting memory errors. This can help reduce
downtime caused by memory errors. Fully buffered DIMMs provide additional availability
features, including CRC (cyclic redundancy check) monitoring.
• The x3550 offers selectable online hot-spare memory and memory mirroring for
redundancy in the event of a noncorrectable memory failure
• Toolless cover removal provides easy access to upgrades and serviceable parts. Similarly,
the Remote Supervisor Adapter II SlimLine and the ServeRAID-8k controller can be
installed and replaced without tools. This means less time (and therefore less money) spent
servicing the x3550. Similarly, hot-swap/redundant HDDs, fans and power supplies, as
well as online hot-spare and mirrored memory, mean greater system uptime while these
components are being serviced.
• New toolless slides ship with the server, together with a Cable Management Arm (CMA),
that allows the rack server to easily slide into place
• IBM Thermal Diagnostics allows the administrator to evaluate thermal data on the server
without taking the hardware offline. This can provide greater server uptime.
• The drop-down light path diagnostics panel and individual light path LEDs quickly lead the
technician to failed (or failing) components. This simplifies servicing, speeds up problem
resolution and helps improve network availability.
• Integrated RAID-1 disk mirroring and RAID-10 striped mirrored arrays standard enable
the server to keep operating in the event of a failure to any one drive.
• IPMI 2.0 supports highly secure remote system power control using data encryption. This
allows an administrator to restart a server without having to visit it in person, saving travel time
and getting the server back up and running quickly and securely. It also adds new features to
those provided by IPMI 1.5, including VLAN support, Serial over LAN, enhanced
authentication and encryption algorithms (RMCP+, SHA-1, AES) and a firmware firewall.
• Temperature-controlled fans adjust to compensate for changing thermal characteristics. At
the lower speeds they draw less power and suffer less wear. Equally important in a crowded
data center, temperature-controlled fans produce less ambient noise in the data center than if

High-Performance Xeon Processors
The x3550 supports up to two high-performance Intel Xeon processors, allowing you to upgrade
to a second processor as your business needs require. The x3550 offers a choice of processor
clock rates, FSB speeds and energy efficiency, including:
• 120W quad-core Xeon processor models X5450, X5460, or X5470 at 3.0, 3.16, 3.33GHz
respectively with 64-bit extensions, a 1333MHz FSB, and 12MB of L2 processor cache (2 x
6MB).
• 50W quad-core Xeon processor model L5420 at 2.5GHz with 64-bit extensions, ultralow
power draw (12.5W per core), a 1333MHz FSB, and 12MB of L2 processor cache (2 x 6MB).
Ultralow power processor L5430 at 2.66GHz is supported via CTO.
• 80W quad-core Xeon processor models E5405, E5420, E5430, E5440 at 2.0, 2.5, 2.66,
2.8GHz (respectively), with 64-bit extensions, a 1333MHz FSB, and 12MB of L2 processor
cache (2 x 6MB). Processor E5410 at 2.33GHz is supported via CTO.
• 65W dual-core Xeon processor model E5205 at 1.86GHz with 64-bit extensions, a 1333MHz
FSB, and 6MB of shared L2 processor cache. 80W dual-core Xeon processor model X5260
at 3.33GHz with 64-bit extensions, a 1333MHz FSB, and 6MB of shared L2 processor cache
is supported via CTO.
• 80W dual-core Xeon processor model 5160 at 3.0GHz, with 64-bit extensions, reduced power
draw, a 1333MHz FSB, and 4MB of shared L2 processor cache.
Dual-core Xeon processors contain two complete processor cores; quad-core processors,
similarly, contain four cores. Some processors contain one unified cache shared by all cores,
while other processors have multiple independent caches (one per pair of cores). The shared
cache is dynamically allocated between the cores as needed. The multiple cores appear to
software as multiple physical processors. The dual-core processors offer considerably higher
performance than a same-speed Xeon processor with a single core. Likewise, quad-core
processors offer considerably higher performance than a same-speed Xeon processor with dual
cores.
Intel Extended Memory 64 Technology (EM64T) 64-bit extensions allow the Xeon processor to
use large memory addressing when running with a 64-bit operating system. This in turn lets
individual software processes directly access more than 4GB of RAM, which was the limit of 32bit addressing. This can result in much higher performance for certain kinds of programs, such as
database management and CAD. Additional registers and instructions (SSE3) can further boost
performance for applications written to use them. Contact your software provider to determine
their software support for EM64T.
The 1066MHz FSB (which connects memory to the processor) boasts a peak rate of 8.53GBps,
or up to one-third higher throughput at the same processor clock speed than an 800MHz FSB
(6.4GBps) used in older systems. The 1333MHz FSB offers a peak rate of 10.67GBps, or up to
two-thirds higher throughput at the same processor clock speed than an 800MHz FSB. This may
result in much higher data transfer rates.
Intelligent Power Capability powers individual processor elements on and off as needed, to
reduce power draw.
Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow
attacks when combined with a supporting operating system.
DDR II ECC Fully Buffered Memory with Chipkill Protection
The x3550 supports up to 32GB of memory in 8 DIMM sockets. Some models include two
512MB DIMMs standard, while others ship with two 1GB DIMMs. The x3550 uses PC2-5300
fully-buffered double data rate II (DDR II) memory (operating at 667MHz) for faster access, and
provides Active Memory features, including advanced Chipkill memory protection, for up to 16X
better error correction than standard ECC memory.
The fully buffered memory in the x3550 provides up to triple the memory bandwidth (up to
21.3GBps in four channels of PC2-5300 fully-buffered DIMMs vs. a maximum of 6.4GBps in two

channels of unbuffered PC2-3200 memory and up to double the system memory capacity (8
DIMMs x 4GB) of the predecessor x336 server (8 DIMMs x 2GB). By performing reads and writes
simultaneously, it eliminates the previous memory read-to-write blocking latency. In addition, it
also offers innovative data reliability and security features to help improve data integrity, including
enhanced CRC protection, data retry on error detect and buffer registers for improved fault
isolation.
For increased availability, the x3550 offers two additional (but mutually exclusive) levels of IBM
Active Memory protection: online memory mirroring, and online hot-spare memory.
Memory mirroring works much like disk mirroring. The total memory is divided into two channels.
Data is written concurrently to both channels. If a DIMM fails in one of the DIMMs in the primary
channel, it is instantly disabled and the mirrored (backup) memory in the other channel becomes
active (primary) until the failing DIMM is replaced. Mirroring can be accomplished with multiples
of four DIMMs (one pair per memory channel). Up to 16GB (four 4GB DIMMS) of memory is
available for use with mirroring enabled. (Note: Due to the double writes to memory, performance
is affected.)
When online hot-spare memory is enabled, using single and/or dual-rank DIMMs one rank is set
aside per branch as online spares in case one of the other ranks fails. The spare rank must have
capacity at least that of the largest active rank. Up to 24GB (using 8 single-rank 4GB DIMMs) or
28GB (using 8 dual-rank 4GB DIMMs) of memory is available when the hot-spare feature is
active. (The lowest-numbered rank of those with the highest capacity in each branch is used for
the hot-spares.)
Either of these features requires operating system support.
When multiples of four DIMMs (4 or 8) are installed, the x3550 operates in four-way interleaved
mode, for higher performance. When only two DIMMs are used, the system defaults to two-way
interleaved mode.
DIMMs must be installed in pairs. Memory is available in kits consisting of two 512MB, 1GB, 2GB
or 4GB DIMMs.
Drive Bays
The x3550 contains either two or four drive bays in all, depending on the model. Some models
offer two 3.5-inch bays that support hot-swap SAS or simple-swap SATA II drives. This
enables up to two slimline (1.0") drives to be installed, totaling up to 600GB (SAS) or 2TB
(SATA).
Other models feature four 2.5-inch bays that support hot-swap SAS drives totaling up to
587.2GB.
Hot-swap drives may be inserted or removed through the front of the server without powering off
the system. Simple-swap drives can be inserted or removed through the front of the server as
well; however, the system power must first be turned off.
For additional storage, a direct-attach, NAS or SAN external expansion option can be added,
using an optional controller.
4
A 24X/24X/24X/8X speed (ultraslim, 0.5”) CD-RW/DVD-ROM Combo drive with an IDE interface
ships standard in all x3550 servers. No diskette drive is supplied with any model; an external
USB floppy drive may be used, if needed.
Disk Controllers
All SAS-equipped x3550 models include an integrated Adaptec AIC9580W Serial-Attach SCSI
(SAS) controller. This controller supports up to four internal SAS LVD (low-voltage differential)
drives. SATA models have a separate SATA controller, which supports up to two internal SATA
drives.
The integrated ServeRAID-8k-l controller offers hardware RAID-0/1/10 support and 32MB of fast
PC2-4200 DDR2 cache for the SAS drives. The ServeRAID-8k option adds three additional
RAID levels, RAID-1E, 5 and 6, along with 256MB of cache memory for higher performance, and
battery backup, without consuming a valuable adapter slot.
5
The SAS controller provides data transfer speeds of up to 300MB per second in each direction
(full-duplex) across the SAS bus, for an aggregate speed of 600MBps, nearly double that of
Ultra320 SCSI’s 320MBps (half-duplex) bandwidth. The serial design of the SAS bus allows
maximum performance to be maintained as additional drives are added.
The SATA controller integrated in the SATA models supports up to two internal SATA II drives,

A highly available and expandable, rack-dense, 1U dual-socket SMP server, for application
serving in Web environments
with maximum data transfer rates of up to 300MB (half-duplex) per second. This is throughput is
similar to that of Ultra320 SCSI (320MBps, half-duplex). The SATA models also include firmware
support for RAID-0/1. The system can be upgraded to hardware-based RAID-0/1/10/1E/5/6 for
higher performance, using the same IBM ServeRAID-8k SAS/SATA controller as the hot-swap
server models.
For external storage, the MegaRAID 8480 controller enables connection to up to four IBM
System Storage EXP3000 SAS expansion units (48 HDDs total). It provides RAID-0/1/10/5/50
support and 256MB of onboard cache.
Additional external storage is available using one of several supported direct-attach, iSCSI or
SAN controllers.
Large HDD Storage Capacity
The x3550 offers a choice of disk storage, supporting up to two (3.5-inch) or four (2.5-inch) hotswap high-performance SAS drives, or two (3.5-inch) simple-swap SATA drives:
3.5-inch SAS
• 15,000 RPMs — 73.4, 146.8 or 300GB (600GB maximum)
2.5-inch SAS
• 10,000 RPMs — 73.4 or 146.8GB (587.2GB)
• 15,000 RPMs — 73.4GB (293.6GB)
3.5-inch SATA
• 7,200 RPMs — 160, 250, 500, 750GB or 1TB (2.0TB)
2-5-inch drives not only require less space than 3.5-inch drives, they weigh less, consume half
the power, produce less noise, seek faster, and offer increased reliability.
Simple-swap SATA drives are not hot-swappable (the system must first be powered off);
however, no tools or jumpers are required for installation and removal, allowing for faster, simpler
servicing than fixed drives. The hot-swap SAS drives use the Converged Tray for
™
interchangeability with other IBM System x systems. If you need more storage space, terabyte
capacities are possible with external direct-attach, NAS and SAN solutions.
High-Performance Adapter Slots
The x3550 provides two x8 (“by 8”) 4GBps PCI-E (PCI Express) adapters standard. Each is
capable of supporting x1/x4/x8 adapters at full speed. Both slots are half-length/full-height. If
desired, the riser card containing slot 2 may optionally be replaced with one that provides one
half-length/full-height (1GBps) 133MHz PCI-X slot instead.
PCI-Express is a high-performance, low-latency, next-generation serial I/O bus that is rapidly
replacing the older parallel PCI and PCI-X buses. A x8 PCI-E adapter offers approximately four
6
times the maximum throughput of a 133MHz PCI-X adapter . (A x1 adapter offers throughput
similar to a 66MHz PCI-X slot.)
Because the SAS, ServeRAID-8k and 8k-l, dual Gigabit Ethernet, systems management and
video controllers are integrated onto the system board, the two adapter slots are both available,
which offers a wide degree of latitude in expansion options.
Dual Gigabit Ethernet Controllers
The x3550 includes two integrated Broadcom 5708 Gigabit Ethernet controllers for up to 10X
higher maximum throughput than a 10/100 Ethernet controller, as well as support for Jumbo
Frames and TOE (TCP Offload Engine).
Jumbo Frames—those larger than the standard frame (packet) size of 1,500 bytes—can be
more efficient, dramatically increasing network performance and reducing server CPU overhead.
TOE helps improve overall system performance by offloading TCP/IP protocol processing from
the system microprocessor to the onboard Ethernet TOE processor.
®
It also supports highly secure remote power management using IPMI 2.0, plus Wake on LAN
and PXE (Preboot Execution Environment) flash interface. Optional PCI adapters offering failover
and load balancing between adapters are available for added throughput and increased system
availability.
5
Data transfer rates depend on many factors and are often less than the maximum possible.
6
Actual throughput will depend on the adapter vendor’s implementation.

Ultra-Efficient Cooling
Strategically located fans, combined with efficient airflow paths, provide highly effective system
cooling for the x3550, known as Calibrated Vectored Cooling. The base server with one power
supply includes ten hot-swap fans, for redundant cooling. The second processor option also
includes two more fans. In addition, each power supply also contains a fan.
The system contains three cooling zones. Zone 1 (incorporating four fans) cools all 8 DIMM
sockets. Zone 2 (four fans) cools the primary processor, and Zone 3 (two or four fans) cools the
second processor.
The fans automatically adjust speeds in response to changing thermal requirements, from a
minimum of 7,750 RPMs to a maximum of 15,000 RPMs, depending on the zone and internal
temperatures. When the temperature inside the server increases, the fans speed up to maintain
the proper ambient temperature. When the temperature returns to a normal operating level, the
fans return to their default speed. Why not simply run the fans at 100% capacity all the time? For
several good reasons: to reduce the ambient noise, reduce the wear-and-tear on the fans and
reduce the server power draw. The reduction in ambient noise and power draw may be relatively
minor for a single server, but put dozens or hundreds in a data center and it can make a big
difference!
In addition, the server uses hexagonal ventilation holes in the chassis. Hexagonal holes can be
grouped more densely than round holes, providing greater airflow through the system cover.
This cooling scheme is important because newer, more powerful processors generate a
significant amount of heat, and heat must be controlled for the system to function properly.
Light Path Diagnostics
Light path diagnostics enables a technician to quickly identify and locate a failed or failing system
component, such as a specific fan or memory DIMM. This enables quick replacement of the
component, which helps increase server uptime and lower operating costs.
The front of the server has an LED indicator light to show possible component failures. If the front
LED indicates an error condition, by pressing a button on the front of the server an LED panel will
pop out and drop down for easy viewing without the need to open the server cover or remove the
server from the rack. The light path diagnostics panel tells the servicer which component requires
attention. In addition, many components have their own identifying LEDs. For example, each of
the eight memory modules has an LED next to the socket, as do both processors, all adapter
slots, all fans, all power supplies, the voltage regulator module and the service processor,
allowing the servicer to easily identify exactly which component needs servicing. By following the
“light path,” the component can be replaced quickly, and without guesswork. (Note: In the event
of a failed DIMM, the system will restart and mark the DIMM as bad while offline, thus allowing
the system to continue running, with reduced memory capacity, until serviced.)
Hot-Swap/Redundant Components
System availability is maximized through the extensive use of hot-swap and redundant
components, including:
• Redundant memory protection (with online hot-spare memory or memory mirroring
enabled)
• Hot-swap, redundant hard disk drives (with RAID-1/10 protection standard and three other
RAID levels optional)
• Hot-swap, redundant power supplies (optional)
• Hot-swap, redundant cooling fans (standard)
Other Features
• Six USB 2.0 ports — Provides flexibility to add high-speed external devices. The USB 2.0
specification supports up to 480Mbps transfer rates. (Note: Not all USB 2.0 devices are
capable of achieving this rate.) Two ports are provided on the front of the server and four on
the back.
• Remote Supervisor Adapter II SlimLine support — This optional full-function systems
management adapter adds local and remote management functions without consuming a

Rack Cable Management and KVM Console Switching
IBM Advanced Cabling Technology (ACT) is an optional feature that offers many advantages
over standard KVM cabling across the entire System x and xSeries product line. So now you can
interconnect all of your servers with one smart cabling architecture. ACT cabling eliminates the
need for one-to-one direct connections between each server and a KVM switch by using a daisychain approach.
The snarl of cabling behind most racks is at best inconvenient to work around and at worst an
expensive logistical nightmare, requiring the rewiring of servers, PDUs, KVM switches, and other
equipment whenever a rack server is added or removed. Even worse, the veil of cables blocks
rack airflow and can actually contribute to equipment failure due to overheating. ACT cabling is
the solution for reducing behind-the-rack cabling by as much as 87%.
The illustration below shows a sample ACT configuration:
Directly
Via Daisy-Chain
• Max.16 servers per port
All CAT5, 5e, 6
cabling
Via Secondary
Switch
Conventional cabling has bulky KVM cables exiting each server, which then connect to a KVM
switch. The cables exiting a series of KVM switches must then be aggregated via additional KVM
switches and PDUs, which only increases the number—and cost—of cables, KVM switches and
PDUs. Instead, the daisy-chain approach of ACT cabling uses readily available, inexpensive
CAT5 and 6 cabling to considerably reduce the number of cables, KVM switches, and PDUs
needed, rather than increasing them. If a server is removed or added, no complicated rewiring is
needed. One cable connects the first server in the rack to the next, and so on. Up to 16 servers
form a chain; up to 8 chains can connect to one Local Console Manager (LCM); 16 LCMs can
connect to one Global Console Manager (GCM). In this manner, up to 2,048 servers can be
centrally managed. Equally importantly, with ACT—unlike some other offerings—everything is
done externally via cabling; no special adapters are required.

updated frequently to ensure that the latest compatibility information is always at your fingertips.
The IBM Standalone Solutions Configuration Tool (SSCT) is a downloadable tool that
simplifies the often complex chore of configuring a full rack of servers (including blade servers)
and confirming that you have all the cables, power distribution units, KVM (keyboard, video and
mouse) switch boxes and other components you need, as well as the proper airflow clearances,
electrical circuits and other environmental conditions.
IBM System x and BladeCenter Power Configurator helps IT managers plan for data center
power needs, by providing the following information for specific configurations of System x and
BladeCenter systems: power input (watts), PDU sizing (amps), heat output (BTUs), airflow
requirements through chassis (CFM), VA rating, leakage current (mA), and peak inrush current
(amps).
IBM ServerGuide (installed from CD) simplifies the process of installing and configuring System
x and xSeries servers. ServerGuide goes beyond mere hardware configuration by assisting with
®
®
the automated installation of the Microsoft Windows Server 2000 and 2003 operating systems,
device drivers and other system components, with minimal user intervention. (Drivers are also
included for support of Novell NetWare, Red Hat Linux and SUSE LINUX.) This focus on
deployment helps you reduce both you total cost of ownership and the complexity that
administrators and technical personnel face.
™
IBM Electronic Service Agent is an innovative “call home” feature that allows System x and
BladeCenter servers to automatically report hardware problems to IBM support, which can even

• VLAN support
• Enhanced authentication and encryption algorithms (RMCP+, SHA-1, AES)
• Local update of BMC firmware
• Firmware firewall
• Support for IPMI v2.0 compliant management software (e.g., xCAT)
• Other mandatory and optional IPMI BMC functions
The BMC alerts IBM Systems Director to anomalous environmental factors, such as voltage and
thermal conditions—even if the server has failed.
The x3550 also supports an optional IBM Remote Supervisor Adapter II SlimLine for additional
systems management capabilities, including:
• Predictive Failure Analysis for system fans
• Graphical console redirection over LAN
• Web-based out-of-band control
• Windows “blue screen” capture
• Remote virtual floppy and CD-ROM
• High-speed remote redirection of PCI video, keyboard and mouse
• SSL (Secure Socket Layer) and LDAP (Lightweight Directory Access Protocol) support
IBM developed IBM Systems Director Active Energy Manager for x86 to put control of system
power-saving features at the fingertips of administrators. Active Energy Manager is designed to
take advantage of new features, such as monitoring power usage and balancing the performance
of the system according to available power input. It provides the ability to plan and predict power
consumption based on your hardware configuration. It also helps enable you to reduce the
infrastructure required for redundancy, by using fewer servers on smaller power feeds and
potentially lowering your overall data center support costs. It does this by inventorying all
components, then adding up the total power draw and tracking the usage. It also includes power
management and capping features to help administrators manage or reduce power usage.
Automatic Server Restart (ASR) helps reduce downtime by restarting the server automatically
in the event of a system lockup. ASR technology is a combination of hardware circuitry tied into
the server’s system reset function and a device driver. As long as the server continues running,
the ASR watchdog timer will keep being reset, but if the operating system crashes or the
hardware freezes somehow the ASR software will be unable to reset the hardware timer. If the
timer is not reset within five minutes, it automatically triggers the ASR hardware, which
immediately restarts the server (and logs an ASR event with IBM Systems Director). These
features are designed so that no more than five minutes can pass before the server is restarted.
Wake on LAN permits the server to be remotely powered on if it has been shut off. Once
powered up, the server can be controlled across the network, using the Preboot Execution
Environment (PXE).
Like Wake on LAN, PXE is system firmware. It enables software such as the optional IBM
Remote Deployment Manager to take control of a system before the BIOS, operating system or
applications are loaded (using Wake on LAN/PXE) and lets an administrator perform many lowlevel tasks remotely that would otherwise require a visit to each system. These tasks may include
such things as formatting a hard disk drive, updating system firmware, or deploying a Windows or
Linux operating system.
Text Console Redirection support allows the administrator to remotely view x3550 text
messages over serial or LAN. An optional upgrade to the Remote Supervisor Adapter II
SlimLine adds graphical console redirection.
Predictive Failure Analysis (PFA) is designed to allow the system to detect impending failure of
supported components (memory, power supplies, hard disk drives, and fans) before actual
failure, and alert the administrator through IBM Systems Director. This gives you the ability to
replace the failing component before it fails, resulting in increased uptime.
IBM Systems Director software for advanced workgroup management is included with the
x3550. IBM Systems Director comes with a portfolio of tools, including Management Processor
Assistant, Rack Manager, RAID Manager, Update Assistant and Software Distribution. Systems
Director Active Energy Manager for x86, System Availability (a no-charge download) and
Capacity Manager (sold separately) are available as add-ons for additional server management
and increased availability. IBM Systems Director provides a single uniform graphical interface for
all of these systems management functions.
IBM Systems Director enables you to customize thresholds and monitor system components (for
things like temperature, voltage regulation, etc.) to help maximize uptime.

Key Options
IBM options for System x servers help you take your servers to a
higher level
You know can rely on System x options to supply a complete solution for your business needs.
Options help you create an optimized server system to meet your data protection, storage and
availability needs. Every IBM option is designed and tested for peak performance and flexibility,
helping to maximize your return on investment. The combination of System x servers and options
lets you keep your fingers on the pulse of your e-business.
Processors — The Intel Xeon processor provides high clock rates, dual- or quad-cores, 64-bit
extensions, a large cache and advanced features for availability and manageability. Large cache
size, combined with a fast 1333MHz or 1066MHz front-side bus, reduces memory latency and
facilitates the movement of data through the processor and I/O devices. (Note: System
performance depends not only on the number of processors in the server but also on the power
and functionality of each processor.) Adding a second processor may be a cost-effective way to
achieve significant performance improvements.
Memory — Memory is a significant factor in systems application performance. Adding more
memory to a System x server is one of the most effective ways to increase application
performance. For best performance in a server with a dual-core processor, there should be twice
as much memory available as for a single-core processor. The x3550 takes memory upgrades in
pairs and provides either two-way or four-way interleaving (depending on the number of DIMMs
installed).
Hard Disk Drives — IBM hard disk drives help you improve the transaction and cost
performance of your System x servers. The choice of hard disk drives can be a critical aspect of
maximizing the I/O throughput of the system. SAS hard disk drives are available for the x3550
with capacities up to 300GB (3.5-inch) apiece at 15,000 RPMs, up to 146.8GB (2.5-inch) apiece
at 10,000 RPMs, or up to 73.4GB apiece (2.5-inch) at 15,000 RPM. 3.5-inch Serial ATA hard
disk drives are available with capacities up to 1TB apiece at 7,200 RPMs.
Power Supply — The optional second power supply for the x3550 enables redundancy for hotswap power.
Remote Supervisor Adapter II SlimLine — The x3550 includes a plethora of systems
management features built-in; however, sometimes additional management capability is needed.
In those situations, the Remote Supervisor Adapter II SlimLine not only offers powerful new
features, it does so without taking up a valuable PCI-X or PCI-E adapter slot, instead using a
dedicated slot on the motherboard.
ServeRAID Controllers — System x servers using embedded ServeRAID-8k technology allow
companies to build a reliable foundation for business-critical computing. IBM ServeRAID
technology allows an array consisting of multiple physical hard disk drives to be treated as one
logical drive. ServeRAID technology also allows data to be stored redundantly, across multiple
hard disk drives— enhancing both the integrity and the availability of the data. SAS and SATA
ServeRAID controllers offer enhanced performance due to onboard processors and cache.
Because IBM ServeRAID controllers can help significantly improve data transfer rates, this
technology is extremely effective when implementing demanding, transaction-oriented
applications. By employing the advanced fault tolerance of IBM ServeRAID technology,
companies can effectively implement networked business systems that require large amounts of
storage space for data and applications that must be available for their businesses to continue
operating.
The optional ServeRAID-8k SAS/SATA controller offers enhanced performance over the
integrated ServeRAID-8k-l controller (SAS models), 256MB of battery-backed cache memory,
and supports six RAID levels: 0 (striping), 1 (mirroring), 10 (mirroring and striping), 1E (enhanced
mirroring, supporting odd numbers of drives), 5 (striping with parity), and 6 (striping with double
parity).
The optional MegaRAID 8480 SAS controller offers high performance and 256MB of cache
memory (with optional battery backup) for external SAS storage capacity. The adapter supports
five RAID levels: 0 (striping), 1 (mirroring), 10 (mirroring and striping), 5 (striping with parity), and
50 (striping/mirroring with parity).
External Storage — The IBM TotalStorage DS3000, DS4000, DS6000, and DS8000 series, as
well as the System Storage DS4000, N3000, N5000, and N7000 series, comprise a powerful
and broad shared storage family with integrated management software designed to meet
midrange and enterprise needs. For lower-end needs, IBM offers the TotalStorage DS300 and
DS400 storage enclosures.
External SAN, iSCSI, and direct-attach storage is available using one of several IBM System
Storage and TotalStorage host bus adapters. Additionally, external LAN-attached tape storage is
available.
The iSCSI HBA Adapter for IXA Connectivity is a PCI adapter for selected System x and

xSeries servers that provides a direct 1GBps link to an IBM System i5 or iSeries server. This
connection enables you to centralize your Microsoft Windows and System i5 or iSeries storage
and consolidate the operations and backup of your System x, xSeries, System i5 and iSeries
systems into a single infrastructure. It enables the tightest possible integration between Windows
and System i5/iSeries data and applications, and allows as many as 32 servers to attach to one
System i5 or iSeries system to share the iSeries server’s systems management, DVD, tape and
disk storage via the iSeries dynamic virtual storage architecture. This can take the place of a SAN
if you have an established System i5 or iSeries infrastructure.

MB, GB and TB = 1,000,000, 1,000,000,000 and
1,000,000,000,000 bytes, respectively, when referring to
storage capacity. Accessible capacity is less; up to 3GB is
used in service partition. Actual storage capacity will vary
based upon many factors and may be less than stated.
Performance is in Internal Throughput Rate (ITR) ratio based
on measurements and projections using standard IBM
benchmarks in a controlled environment. The actual
throughput that any user will experience will depend on
considerations such as the amount of multiprogramming in the
user’s job stream, the I/O configuration, the storage
configuration and the workload processed. Therefore, no
assurance can be given that an individual user will achieve
throughput improvements equivalent to the performance ratios
stated here.
Maximum internal hard disk and memory capacities may
require the replacement of any standard hard drives and/or
memory and the population of all hard disk bays and memory
slots with the largest currently supported drives available.
When referring to variable speed CD-ROMs, CD-Rs, CD-RWs
and DVDs, actual playback speed will vary and is often less
than the maximum possible.
