In the world of business performance computing, you require more than just speed. The
challenge is to maintain high availability while minimizing costs on power and cooling. The twosocket, dual-core IBM® System x3655, incorporating IBM X-Architecture™ features, meets that
challenge. The x3655 was designed to eliminate performance-robbing system architecture
bottlenecks through the use of separate, high-speed links between the processors, main memory,
and I/O. Equally importantly, it was designed with numerous high-availability, power monitoring,
and proactive power-saving features.
The x3655 supports the latest dual-core AMD Opteron processors with DirectConnect
Architecture and HyperTransport technology to offer impressive computing power in a 2U rackoptimized design. Accommodating compute-intensive and memory-intensive applications, this
server is ideal if you require large memory bandwidth and high floating-point performance at
an affordable price. The x3655 offers up to 64GB1 of industry-standard PC2-5300 DDR2 memory
with optional Chipkill™2 ECC (Error Checking and Correcting) protection—for high performance
and reliability. For even higher levels of availability, the x3655 also offers online hot-spare
memory. Dual integrated high-speed Gigabit Ethernet controllers are standard—offering TOE
(TCP offload engine) support, load-balancing and failover capabilities. IBM eXtended I/O™
features high-performance adapter slots (four PCI-E slots, with the option of replacing one PCIE slot with, one PCI-X or one HTX slot).
All models offer a choice of high-performance hard disk drives with a variety of high-performance
internal hard disk and backup drive configurations: up to six 3.5-inch Serial-Attach SCSI (SAS)
hot-swap drives with an internal storage capacity of 1.8TB3, or up to six 3.5-inch Serial ATA
(SATA) hot-swap drives (4.5TB), or eight 2.5-inch SAS hot-swap drives (1.17TB). It also
supports an internal tape drive (in place of two of the 3.5-inch drives. The integrated
ServeRAID™-8k-l SAS (Serial Attach SCSI) controller provides hardware-based RAID-0/1/10
support. Additional RAID support, including battery-backed cache, is available via the optional
IBM ServeRAID-8k controller, delivering RAID-5/6 capability. Up to 21 x3655 servers can be
installed in a single 42U rack, for a total of up to 42 processors and 84 processor cores. 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 x3655 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. A pop-out/drop-down light path diagnostics panel enables quick servicing of the
system if a hardware problem develops. These advanced features help maximize network
availability by increasing uptime, as do integrated RAID; Active Memory™, temperaturecontrolled hot-swap/redundant fans with Calibrated Vectored Cooling™; hotswap/redundant power, IPMI 2.0 support, including highly secure remote power control and
Serial over LAN; as well as text-console redirect over LAN.
Maximum memory and disk capacity may require the replacement of standard components with the largest supported component
available. 64GB capacity using 4GB DIMMs requires a 2-processor system in order to use all 16 DIMM slots. In a uniprocessor
configuration, only 8 total DIMM slots are available; thus a uniprocessor system is limited to 32GB of RAM (8 x 4GB).
All models require Chipkill-enabled DIMMs for Chipkill protection. The 512MB DIMMs provided standard are not Chipkill-enabled.
TB equals 1,000,000,000,000 bytes when referring to hard disk drive capacity. Accessible capacity may be less.

integrated memory controller offer superior performance capable of tackling the toughest
jobs. 64-bit extensions provide the flexibility to run 32-bit and 64-bit applications
• High-throughput DDR2 memory uses less power than older DDR1 or fully buffered memory.
• 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.
• Four high-speed adapter slots offer potential investment protection by supporting highperformance adapters, such as Gb Ethernet, Fibre Channel and InfiniBand cards.
• Up to six 3.5-inch hot-swap SAS or SATA, or up to eight 2.5-inch hot-swap SAS hard disk
drives offer high-performance with high availability.
• The integrated dual Gigabit Ethernet controllers with IPMI 2.0 support provide high-speed
network communications.
• The TCP Offload Engine (TOE) feature offers higher performance for TCP/IP traffic, with less
overhead on the system processor. (A no-charge firmware upgrade, available in 4Q/06, is
required to enable this hardware feature.)
• A high degree of device integration—including SAS, RAID, dual Gigabit Ethernet, systems
management and video controllers—lowers costs and frees up valuable adapter slots.
The x3655 has the ability to grow with your application requirements, thanks to:
• A choice of processors with 1.8, 2.0, 2.6, and 2.8GHz clock rates and 68 or 95W power draw.
• Up to 64GB of high-speed DDR2 system memory (32GB per processor).
• IBM eXtended I/O, which provides four available high-performance adapter slots (one x16,
two x8, and one x4 PCI-E; optionally a riser card containing either one PCI-X/133 or one
HTX slot can replace the x16 PCI-E riser) in all models.
• Hardware-based support for RAID-0/1/10 is provided standard via an integrated ServeRAID8-l controller with 32MB of cache. Installing a ServeRAID-8k option upgrades the system to
256MB of low-cost cache (with optional battery backup) to enable high-performance internal
and external hardware RAID support, and allows the x3655 to offer six RAID levels: RAID-0,
1, 10, 1E, 5, and 6.
• The seven USB 2.0 ports are up to 40X faster4 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, four are on the back, and one port is internal.
The internal port supports one tape or GoVault EZ backup drive.
• A choice of up to four internal 3.5-inch HDDs and a backup (internal tape or GoVault) drive,
six 3.5-inch HDDs without a backup drive, or eight internal 2.5-inch HDDs and a backup
drive—depending on the model—offer a variety of storage options. The 3.5-inch models
provide a maximum of 1.8TB of internal hot-swap SAS storage (1.2TB with an internal backup
drive installed) or 4.5TB of internal hot-swap SATA storage (3.0TB with internal backup drive).
The 2.5-inch models support up to 1.17TB of hot-swap SAS storage in addition to an internal
backup drive. Additionally, direct-attach, iSCSI or Fibre Channel-attached storage can be
attached using IBM System Storage or TotalStorage servers.
Data transfer rates may be less than the maximum possible.

A perfect mix of IBM mainframe-inspired reliability and application performance
Powerful systems management features simplify local and remote management of the x3655:
• The x3655 includes a Baseboard Management Controller (BMC) to monitor server
availability, perform Predictive Failure Analysis, etc., and trigger IBM Director alerts. The BMC
enables service personnel to use sophisticated diagnostic tools, such as light path diagnostics
and Serial over LAN, to resolve problems quickly.
• IBM PowerExecutive 2.0, an IBM-exclusive, is designed to take advantage of new system
power management features, by providing power monitoring, and power capping features.
• Integrated IPMI 2.0 support alerts IBM Director to anomalous environmental factors, such as
voltage and thermal conditions. It also supports highly secure remote power control using
data encryption.
• Text Console Redirection support allows the administrator to remotely view x3655 text
messages over Serial or LAN.
• IBM Director 5.x is provided for proactive systems management. It comes with a portfolio of
tools, including IBM PowerExecutive, Management Processor Assistant, RAID Manager,
Update Assistant, and Software Distribution. In addition, IBM Director offers extended systems
management tools for additional server management and increased availability.
• 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. It also adds PFA support for fans. And it
does all this without consuming a valuable adapter slot.
Availability and Serviceability
The x3655 provides many features to simplify serviceability and increase system uptime:
• x3655 servers support Chipkill-enabled memory DIMMs (1GB or larger capacity). Chipkill
memory is up to 16X better than standard ECC memory at correcting memory errors. This can
help reduce downtime caused by memory errors.
• The x3655 offers selectable online hot-spare memory 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 server. Also, hot-swap/redundant HDDs, fans and power supplies, as well as
online hot-spare memory, can mean greater system uptime while components are being
• The pop-out/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 enable the server
to keep operating in the event of a failure to any one drive. Optional RAID-5/6 is available
simply by plugging in the slotless ServeRAID-8k controller.
• 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
they were constantly running at full speed.
The three-year (parts and labor) limited onsite warranty5 helps offer peace of mind and
greater potential investment protection than a one-year warranty does.

Key Features
High-Performance Dual-Core Opteron Processors
The x3655 supports up to two high-performance AMD Opteron processors, allowing you to
upgrade to additional processors as business needs dictate. Each CPU supports up to eight
DIMM slots, providing up to 16 DIMM slots and 64GB of max memory in a two-processor system
and provides an integrated memory controller to reduce memory bottlenecks.
The x3655 offers a choice of processor clock rates:
• 95W dual-core AMD Opteron models 2210, 2212, 2218 or 2220 operating at 1.8, 2.0, 2.6 or
2.8GHz (respectively), with 64-bit extensions, reduced power draw, and 2x1MB of L2
processor cache (1MB per core)
• 68W dual-core AMD Opteron model 2210 HE operating at 1.8GHz, with 64-bit extensions,
low power draw, and 2x1MB of L2 processor cache (1MB per core)
System power-efficiency is crucial for businesses looking to increase their computing strength
to spread the workload without outgrowing their current data center. With the power-efficient AMD
Opteron dual-core processors, increased performance-per-watt improves compute capacity
within the same infrastructure space. By replacing old Opteron-based servers with new x3655
servers using the new power-efficient processors, you can reduce the number of servers needed
by up to 45%, with equivalent performance and as much as a 44% power reduction! Or, you can
nearly double the performance in the same space while still saving on power, when implementing
a one-to-one server replacement.
HyperTransport technology is a high-speed, low-latency, point-to-point link, designed to
increase the communication speed between circuits. It eliminates a key bottleneck currently
caused by the stepped-down front side bus (FSB) used in other system architectures, by
accessing memory at the same speed as the processor. This permits the fastest possible access
to CPU and memory. The x3655 incorporates the latest version of HyperTransport technology
(3.0), which provides an aggregate bandwidth of up to 41.6GBps.
The integrated memory controller and the L2 cache run at the full processor clock rate.
AMD PowerNow! technology with optimized power management dynamically reduces processor
power draw based on workload. This can result in a power savings of up to 75% per processor at
CPU idle.
Opteron offers outstanding 32-bit and 64-bit performance. With a 64-bit operating system,
Opteron is capable of running both 64-bit and 32-bit applications concurrently.
Go to http://amd.com for more information on HyperTransport technology.
DDR II ECC Memory with Chipkill Protection
The x3655 supports up to two processors. Each processor has access to 8 DIMM slots. The
maximum memory capacity is 64GB in 16 DIMM slots (32GB per processor installed). (Note: The
first four DIMM slots per processor operate at 667MHz; if more than four DIMMs are installed on
either processor card, the overall memory speed drops to 533MHz.) The system provides Active
Memory™ features, including advanced Chipkill memory protection, for up to 16X better error
correction than standard ECC memory. Chipkill protection is a global setting. (That is, either all
processors have Chipkill enabled or none do.)
For increased availability, the x3655 also offers another level of IBM Active Memory protection:
online hot-spare memory. This feature, too, is enabled on a global basis.
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 60GB per processor (using 16 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.) Note: This
feature requires operating system support.
The x3655 memory operates in two-way interleaved mode for increased performance.
DIMMs must be installed in pairs. Memory is available in kits consisting of two 512MB (nonChipkill), 1GB, 2GB or 4GB DIMMs.
Large HDD Storage Capacity
The x3655 offers a choice of disk storage, supporting up to six 3.5-inch hot-swap SAS or SATA
drives, or up to eight 2.5-inch hot-swap SAS drives:
3.5-inch SATA
• 7,200 RPMs — 80, 160, 250, 500 or 750GB (4.5TB maximum)
Please see the Legal Information section for important notices and information.
A perfect mix of IBM mainframe-inspired reliability and application performance
3.5-inch SAS
• 10,000 RPMs — 36.4, 73.4, 146.8 or 300GB (1.8TB)
• 15,000 RPMs — 36.4, 73.4 or 146.8GB (880.8GB)
2.5-inch SAS
• 10,000 RPMs — 36.4, 73.4, or 146.8GB (1.17TB)
If you need more storage space, terabyte capacities are possible with external direct-attach,
iSCSI, and SAN solutions.
Backup Devices
The x3655 supports several internal and external backup options. Supported drives include:
• 36/72 GB DDS-5 Tape Drive (SCSI)
• 80/120 GB GoVault EZ Drive (SATA)
• 80/160 GB Half High VS160 Tape Drive (SCSI)
• 400/800 GB LTO-3 Ultrium Tape Drive (external SCSI)
Drive Bays
The x3655 contains either seven or ten drive bays in all, depending on the model. Some models
offer six 3.5-inch bays that support hot-swap SAS or SATA drives. This enables up to six
slimline (1.0") drives totaling up to 1.8TB (SAS) or 4.5TB (SATA) to be installed.
An internal half-high DDS5 tape drive or GoVault EZ drive can be installed in place of two of
the HDDs. This offers the confidence of internal tape backup, while still leaving four available
drive bays (for a total disk capacity of up to 1.2TB of SAS or 3.0TB of SATA storage,
Other models feature eight 2.5-inch bays that support hot-swap SAS drives totaling up to
587.2GB. In addition to the eight 2.5" HDD bays, there is a dedicated bay for a half-high DDS5
tape drive or GoVault EZ drive.
A 24X/10X/24X/8X6 speed (ultraslim, 0.5”) CD-RW/DVD-ROM combo drive with an IDE interface
ships standard in all x3655 servers. No floppy drive is supplied with any model; an external USB
floppy drive may be used, if needed.
For additional storage, a direct-attach, FC SAN, or iSCSI external expansion option can be
added, using an optional controller.
Disk/Tape Controllers
All x3655 models include an integrated SAS controller. It provides data transfer speeds of up to
300MB per second7 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
An integrated hardware-based ServeRAID-8k-l controller enables RAID-0/1/10 support and
provides 32MB of PC2-4200 DDR II cache memory. Optionally, a slotless ServeRAID-8k
controller is available for additional performance (via 256MB of battery-backed cache) and RAID
levels (RAID-0/1/10/1E/5/6).
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 SAS/SATA storage is available using
the external SAS port on the system unit, or via one of several supported iSCSI or SAN
The x3655 also includes an IDE controller to support the integrated optical drive. In addition,
dedicated internal USB and SATA ports are available to support an internal DDS5 or DDS6 tape
drive or GoVault EZ Drive removable disk drive.
High-Performance Adapter Slots
The x3655 provides four high-speed adapter slots to fit a variety of needs. Two x8 (“by 8”)
4GBps PCI-E slots (Slots 3 and 4) support x1/x4/x8 cards at full rated throughput. One x4 (“by
4”) 2GBps PCI-E slot (Slot 2) supports x1 and x4 cards. These slots are full-length/low-profile.
Variable read rate. Actual playback speed varies and is often less than the maximum possible.
Data transfer rates depend on many factors and are often less than the maximum possible.
Please see the Legal Information section for important notices and information.
A perfect mix of IBM mainframe-inspired reliability and application performance
In addition, a choice of riser cards supporting full-length/full-height adapters adds any one of the
following to Slot 1: One x16 (“by 16”) 8GBps PCI-E (PCI Express) adapter slot (shipped
standard) supports x1/x4/x8/x16 cards at full rated throughput. Optionally, either one PCI-X/133
or one HTX adapter slot riser can replace the x16 PCI-E riser. Throughput for the HTX slot is
approximately the same as for the x16 PCI-E slot, but with even lower latency. This slot is ideal
for math accelerator and interconnect cards, such as InfiniBand™. The high-performance HTX slot
introduces a unique, highly pipelined, cut-through design that, when paired with an HTX adapter,
can yield a message rate 10 times higher than competitive interconnects. As users tackle larger
and more complex applications with ever-larger clusters, there is a marked increase in message
rates and a decrease in message sizes. The more processors that tackle a given task, the higher
the frequency of small, bursty message communications. Thus, interconnect performance has
become a key factor and the innovation in IBM HTX adapter slots supporting InfiniBand adapters
allows your current applications to run faster and scale higher, helping to improve time-tosolution.
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 x16 PCI-E adapter offers approximately eight
times the maximum throughput of a 133MHz PCI-X adapter8. (A x1 adapter offers throughput
similar to a 64-bit 66MHz PCI-X slot.)
Because the SAS, ServeRAID-8k-l and 8k, dual Gigabit Ethernet, systems management and
video controllers are integrated onto the system board, the adapter slots are all available, which
offers a wide degree of latitude in expansion options.
Dual Gigabit Ethernet Controllers
The x3655 includes dual integrated Broadcom BCM5706 Gigabit Ethernet controllers with TOE
support9, as well as load-balancing and failover capabilities, with up to 10X higher maximum
throughput than a 10/100 Ethernet controller.
TOE helps improve overall system performance by offloading TCP/IP protocol processing from
the system microprocessor to the onboard Ethernet TOE processor.
The controllers also support 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.
Ultra-Efficient Cooling
Strategically located fans, combined with efficient airflow paths, provide highly effective system
cooling for the x3655, known as Calibrated Vectored Cooling. The server includes five hotswap blowers standard. In addition, each power supply contains a fan. Five additional hot-swap
fans can be installed along with the redundant power supply.
The system contains four cooling zones. Zone 1 (incorporating one fan in a nonredundant
configuration or two with redundancy) cools one processor. Zone 2 (one or two fans) cools some
adapter slots and memory DIMMs, Zone 3 (one or two fans) cools the remaining adapter slots
and memory DIMMs, and Zone 4 (two or four fans) cools the second processor, HDDs, power
supplies and system backplane. In addition, each power supply also contains a fan.
The fans automatically adjust speeds in response to changing thermal requirements, from a
minimum speed to maximum 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.
Hot-Swap/Redundant Components
System availability is maximized through the extensive use of hot-swap and redundant
components, including:
Actual throughput will depend on the adapter vendor’s implementation.
A no-charge firmware upgrade, available in 4Q/06, is required to enable this hardware feature.
Please see the Legal Information section for important notices and information.
A perfect mix of IBM mainframe-inspired reliability and application performance
• Redundant memory protection (with Chipkill and/or online hot-spare memory enabled)
• Hot-swap, redundant hard disk drives (with RAID-1/10 protection standard and RAID-1E/5/6
• Hot-swap, redundant power supplies (optional)
• Hot-swap, redundant cooling fans (optional)
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 memory modules has an LED next to the DIMM slot, as do all processors, all adapter slots, all
fans, the power supply, the voltage regulator modules and the service processor. This allows 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 or processor, the system will restart and mark the component as bad while offline, thus
allowing the system to continue running, with reduced capacity, until serviced.)
Other Features
• Seven 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, four are on
the back, and one is internal to support a USB-interface tape or GoVault EZ backup drive.
• High-resolution video — An ATI Radeon ES1000 SVGA video controller provides up to
1280x1024 resolution, with a color depth of 32 bits at 85Hz refresh rate, via two video ports
(one front, one rear) for convenience.
• Remote Supervisor Adapter II SlimLine support — This optional full-function systems
management adapter adds local and remote management functions without consuming an
adapter slot.
• Internal SATA port — Provides easy connection of internal SATA-based backup storage
• Toolless slides — Allows quick rack installation and quicker upgrade and servicing of the
• Cable Management Arm — Simplifies cable management.
• Toolless chassis — The cover can be opened without tools, and many components can be
removed and replaced without tools, including the optical drive, PCI-E, PCI-X and HTX
adapters, as well as the optional RAID controllers. This can save a servicer significant time.
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%.
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.

locations as well as to stand-alone environments. Features include the Baseboard Management
Controller (BMC), IBM PowerExecutive, Automatic Server Restart, Wake on LAN® support, PXE
support, text console redirect, Predictive Failure Analysis, IBM Director and support for an
optional Remote Supervisor Adapter II SlimLine.
The BMC provides industry-standard Intelligent Platform Management Interface (IPMI) 2.0compliant systems management. It provides a number of important system functions, including:
• Monitoring of system and battery voltage, system temperature, fans, power supplies,
processor and DIMM status

IBM developed IBM PowerExecutive to put control of system power-saving features at the
fingertips of administrators. IBM PowerExecutive 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.
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 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 x3655 text
messages over serial or LAN. An optional upgrade to the slotless Remote Supervisor Adapter II
SlimLine adds graphical console redirect.
Predictive Failure Analysis (PFA) is designed to allow the x3655 to detect impending failure of
supported components (processors, memory, voltage regulator modules (VRMs), fans/blowers,
power supplies and hard disk drives) before actual failure, and alert the administrator through
IBM Director. This gives you the ability to replace the failing component before it fails, resulting in
increased uptime.
IBM Director 5.x software for advanced workgroup management is included with the x3655. IBM
Director comes with a portfolio of tools, including Management Processor Assistant, Rack
Manager, RAID Manager, Update Assistant and Software Distribution. IBM PowerExecutive,
System Availability (a no-charge download) and Capacity Manager (sold separately) are available
as add-ons for additional server management and increased availability. IBM Director provides a
single uniform graphical interface for all of these systems management functions.
IBM Director enables you to customize thresholds and monitor system components (for things
like temperature, voltage regulation, etc.) to help maximize uptime.
Extensive System Support Features
The IBM services and technical support portfolio provides world-class, consistent, high-quality
service and support. The x3655 server offers a number of tools and services designed to make
ownership a positive experience. From the start, IBM programs make it easier to plan for,
configure and purchase System x or xSeries servers, get them running and keep them running
long-term. These features include IBM Express Portfolio, IBM ServerProven®, the Standalone
Solutions Configuration Tool, IBM System x and BladeCenter Power Configurator, IBM
ServerGuide, IBM Electronic Service Agent™, Product Customization Services and extensive
technical support offerings.
This System x server is part of the IBM Express Portfolio, designed, developed and priced to
meet the specific needs of midsized businesses. The IBM Express Portfolio of solutions is easy to
acquire, install and manage. And they leverage IBM technology to provide tangible solutions to
help you solve business problems in an on demand world.

systems have been tested on the server and are officially supported to work together. It is
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)
Please see the Legal Information section for important notices and information.
A perfect mix of IBM mainframe-inspired reliability and application performance
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
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 your 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
dispatch onsite service10 if necessary to those customers entitled to onsite support under the
terms of their warranty or an IBM Maintenance Agreement. Electronic Service Agent resides on a
server and provides electronic support and problem management capabilities through a highly
secure electronic dialogue between your systems and IBM. It monitors networked servers for
hardware errors and it can perform hardware and software inventories and report inventory
changes to IBM. All information sent to IBM is stored in a highly secure database and used for
improved problem determination.
Additional services include hardware warranty upgrades and factory-installed Product
Customization Services (PCS), such as asset tagging, hardware integration, software imaging
and operating systems personalization.
IBM offers extensive technical support by phone and via the Web. Support options include links
to forums/newsgroups, problem submission, online shopping support, service offerings, device
drivers for all IBM product lines, software downloads and even upcoming technical seminar
worldwide schedules and registration. Also available are remote installation, configuration and
usage support for System x and xSeries hardware and software, as well as onsite custom
services to give you the level of expertise you require.
Key Options
IBM options for System x servers help you take your servers to a
higher level
You 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 AMD Opteron processor provides dual-cores, 64-bit extensions, a large
cache and an integrated memory controller. DirectConnnect Architecture 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 dual-core processors, there should be twice
as much memory available as for a single-core processor. The x3655 takes memory upgrades in
pairs and provides two-way interleaving.
Power Supply/Cooling — The optional 835W second power supply for the x3655 enables
redundancy for hot-swap power. It also enables redundant cooling by providing five additional
Remote Supervisor Adapter II SlimLine — The x3655 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 offers powerful new features, all
without consuming a valuable adapter slot.
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. 3.5-inch SAS hard disk drives are available for the
For onsite labor, IBM will attempt to diagnose and resolve the problem remotely before sending a technician.

x3650 with capacities up to 300GB apiece at 10,000 RPMs; 2.5-inch SAS drives offer up to
146.8GB at 15,000 RPMs. 3.5-inch SATA drives are available with capacities up to 750GB
apiece at 7,200 RPMs.
Backup Drives — IBM backup drives help you protect your data. Several choices of capacities
(from 36/72GB to 400/800GB), technologies (removable disk cartridge, DDS5, VS160, LTO3),
and interfaces (SCSI, SATA, USB) are available.
ServeRAID Controllers — System x servers using embedded IBM ServeRAID technology allow
companies to build a reliable foundation for business-critical computing. ServeRAID technology
allows an array consisting of multiple physical hard disk drives to be treated as one logical drive.
It also allows data to be stored redundantly, across multiple hard disk drives—enhancing both the
integrity and the availability of the data. ServeRAID controllers offer enhanced performance due
to onboard processors and cache. Because 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 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 integrated ServeRAID-8k SAS controller offers enhanced performance over the
integrated ServeRAID-8k-l controller, 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).
External SAN, iSCSI, and direct-attach storage is available using one of several IBM System
Storage™ and TotalStorage™ host bus adapters.
The IBM TotalStorage DS300 offers remote SAN storage using the iSCSI storage protocol
across IP networks. The DS300 scales up to 4.2TB of storage capacity using standard hot-swap
Ultra320 SCSI HDDs (the same drives as in System x servers) in a 14-drive 3U cabinet. Three
models offer single or dual RAID controllers (with each controller supporting two Gigabit Ethernet
ports), up to 256MB or 1GB of cache memory and dual redundant power supplies and fans. For
low-cost Fibre SAN storage, the DS400, when combined with two EXP400 storage enclosures,
can scale up to 12.6TB of hot-swap SCSI storage, incorporating redundant power, cooling and
dual 2Gbps Fibre Channel controllers.
The IBM System Storage™ DS3000 series is a powerful and affordable new storage family with
integrated management software designed to meet SMB and departmental needs. The DS3000
series is a perfect antidote to SMBs’ largest headache: rapid and uncontrolled proliferation of
data. The DS3200 and DS3400 each offer single-controller and dual-controller models to help
maintain data-availability. The DS3200 is direct-attached storage with support for clustering and a
3Gbps SAS connection to the host. The DS3400 can be direct-attached or used in a SAN
configuration via 4Gbps Fibre Channel connectivity. In addition, the DS3000 expands to 48
drives (via 3 optional EXP3000 expansion units) and 14.4TB of storage.
Midrange TotalStorage DS4000 products are designed to support the large and growing datastorage requirements of business-critical applications. Because DS4000 solutions can support
connectivity distances of up to 10km (6.2 miles) at Fibre Channel rates of up to 2Gbps,
companies can more easily configure offsite System x servers and storage systems to keep
critical data available around the clock—even in the event of a catastrophe.
These storage servers are designed to provide highly-available Fibre Channel RAID protected
storage that provide the foundation for Storage Area Networks (SANs). DS4000 storage servers
deliver scalability up to 32.8TB of Fibre Channel storage or 56TB of SATA storage (DS4500
only). They provide end-to-end Fibre Channel solutions with high-availability fault-tolerant
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 their Microsoft Windows and System i5 or iSeries storage
and consolidate the operations and backup of their 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.
