The x3650 M2 is not simply an upgrade to a previous server. It is one of our new generation of XArchitecture servers. It is a game-changing, completely redesigned rack server using significantly
less power with unified systems management tools, leadership reliability, availability,
serviceability features and broad system flexibility, housed in a compact 2U mechanical package.
The x3650 M2 features Intel® Xeon® 5500 Series 4-core and 2-core processors, and either 8MB
or 4MB of shared cache, to help provide you with the computing power you need to match your
business needs and growth. This new line of Intel processors delivers unprecedented intelligent
performance with features like adaptive performance for applications and environments, turbo
boost and hyper-threading technology, and integrated power gates and automated power
The x3650M2 uses up to 16 DIMMs with 128GB of registered 1333MHz DDR3 memory with
Chipkill™ ECC (Error Checking and Correcting) protection—for high performance and reliability.
For even higher levels of availability, the x3650M2 also offers online memory mirroring. Up to 4
integrated high-speed Gigabit Ethernet controllers with TOE (TCP Offload Engine) and Jumbo
Frame support are available, as are four high-performance adapter slots (PCIe x8). The
x3650M2 offers an optional embedded hypervisor to manage your virtual workloads.
The System x3650 M2 offers a choice of up to twelve high-performance hot-swap hard disk
drives with an internal storage capacity of 6.0TB (twelve 2.5-inch hot-swap Serial-Attached
SCSI (SAS) or Serial-Attached ATA (SATA) HDDs). Twelve optional solid-state drives (SSDs)
are also available to keep power low, improve resiliency, and offer up to 600GB of storage.
Alternatively, up to eight HDDs or SSDs and one internal tape drive can be used. The server
supports a choice of four IBM ServeRAID® storage controllers which provide broad levels of
hardware-based RAID solutions. The ultra-dense 2U form factor allows businesses to increase
their computing power and spread their workload without outgrowing their current data center. Up
to 21 of these 2U servers can be installed in a single 42U rack, for a total of up to 42 processors
and 168 processor cores, 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 x3650 M2 is the Integrated Management Module (IMM) that enables the user to
manage and control the server easily—both locally and remotely. In conjunction with the IMM, the
x3650 M2 comes with a Bosch BMP085 altitude sensor (altimeter) that governs fan rotation
based on altitude, to help lower your energy consumption. The IMM offers a high level of
manageability that is designed to keep costs down and the system up—even when network
usage increases. IBM’s innovative pop-out/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 hot-swap solid-state drives; hotswap/redundant SAS or SATA HDDs, redundant ultra-efficient power supplies and fan
modules; Active Memory™; integrated RAID; temperature-controlled fans with Calibrated

package, the x3650 M2 is the ideal system.
Selling Features
The x3650 M2 offers numerous features to boost performance and reduce costs:
• Up to two 4-core Xeon 5500 Series processors and 8MB or 4MB of cache per processor,
offer superior performance capable of tackling the toughest jobs. 64-bit extensions provide
the flexibility to run 32-bit and 64-bit applications concurrently. Xeon 5500 series processors
offer up to 225% better performance than the previous-generation 5400 series processors and
up to 900% better performance than the single-core processors of a few years ago that you
may still be using.
• Low-voltage processors draw less energy and produce less waste heat than high-voltage
processors, thus helping to reduce data center energy costs. Some 4-core Xeon 5500 Series
processors use only 60W. This is less than half the wattage consumed by older 130W
• Sixteen DIMMs of ultra-fast registered 1333MHz (or 1066MHz or 800MHz) DDR3 ECC
memory with Chipkill1 protection (optional) provides speed, high availability, and a memory
capacity of up 128GB.
• Optional 50GB solid-state drives (SSD) use only 2W of power per drive, vs. 9-10W for 2.5inch HDDs. This is as much as 80% less power than a 2.5 inch HDD would use (with a
corresponding reduction in heat output).
• The x3650 M2 is a leader in server resiliency. With hot-swap power supplies, fan modules,
and storage, the x3650 M2 has no single point of failure.
• An altimeter works in conjunction with IMM to govern fan rotation based on the readings
which it delivers to save money under normal conditions because the fans do not have to
spin at high speed.
• Four high-speed x8 (“by 8”) PCIe Gen 2 adapter slots offer investment protection by
supporting high-performance 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-M5015 (on selected models) provides RAID-0/1/10/5/50 (optional 6/60
with Self-Encrypting Disk (SED)) without consuming a valuable adapter slot. It also offers
higher performance 512MB battery-backed cache.
• Up to twelve 2.5-inch hot-swap SAS hard disk drives offer high-performance with high
availability. The SAS controller provides full-duplex (bidirectional 300MBps) data transfers
for SAS drives.
• The integrated dual Gigabit Ethernet controllers with IPMI 2.0 provide high-speed network
communications. Jumbo Frames offer higher efficiency transfers for large data packets. Two
more NICS can be supported on the planar with an additional Dual Port Gb Ethernet
daughtercard. 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 hot swap SAS/SATA HDDs or SSD drives,
multiple hardware based ServeRAID options, Gigabit Ethernet ports, systems management
and video controllers—lowers costs and frees up valuable adapter slots.
The x3650 M2 has the ability to grow with your application requirements, thanks to
• A choice of four-core or two-core processors with 1.86 to 2.93GHz clock rates, up to 6.4
gigatransfers per second, and 60W to 95W maximum power draw.

supporting two PCI-X/133 adapters can be exchanged for the PCIe slots.
• Installing the ServeRAID-M5015 option upgrades the basic ServeRAID controller with 512MB
of cache (optional battery) to enable higher-performance hardware RAID support, and allows
the x3650 M2 to offer five RAID levels standard: RAID-0/1/10/5/50 (optionally 6/60 with
SED). The optional ServeRAID MR10M controller supports up to four IBM System Storage™
EXP3000 expansion units containing up to 48 SAS HDDs and 14.4TB of external storage.
• The five USB 2.0 ports (two front, two rear, one internal) are up to 40X faster2 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 two are on the back.
The internal port supports a flash drive with embedded hypervisor or an internal tape or IBM
RDX removable disk storage drive.
• A choice of up to twelve 2.5-inch hot-swap SAS/SATA HDDs or solid-state drives, or eight
2.5-inch drives and one internal tape drive, offer a variety of storage options. The SAS and
SATA models provide a maximum of 6.0TB of internal hot-swap storage.
• Alternatively, iSCSI or Fibre Channel-attached storage can be attached using IBM System
Storage™ servers.
Powerful systems management features simplify local and remote management of the x3650 M2:
• The x3650 M2 includes an Integrated Management Module (IMM) to monitor server
availability, perform Predictive Failure Analysis, etc., and trigger IBM Systems Director alerts.
The IMM performs the functions of both the Baseboard Management Controller (BMC) of
earlier systems and the Remote Supervisor Adapter II and is upgradeable to remote
• An optional Virtual Media Key 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 (cKVM). And it does all this without consuming a valuable adapter slot.
• Integrated industry-standard Unified Extensible Firmware Interface (UEFI) next-generation
BIOS. New capabilities include:
– Human readable event logs — no more beep codes
– Complete out-of-band coverage by the Advance Settings Utility to simplify remote setup
– A complete setup solution, allowing adapter configuration functions to be moved into UEFI
– Consistent firmware management across an entire product line
• Integrated Trusted Platform Module (TPM) 1.2 support.
• 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.
• Text Console Redirection support allows the administrator to remotely view x3650 M2 text
messages over Serial or LAN.
• The completely redesigned IBM Systems Director is included for proactive systems
management. IBM Systems Director comes with a portfolio of tools, including IBM Systems
Director Active Energy Manager, IBM Service and Support Manager, and others. 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.
• IBM Systems Director Active Energy Manager, an IBM-exclusive, is designed to take
advantage of new system power management features, by providing actual realtime energy
monitoring and reporting features.
Availability and Serviceability
The System x3650 M2 provides many features to simplify serviceability and increase system

• Toolless cover removal provides easy access to upgrades and serviceable parts. Similarly,
the Virtual Media Key and the ServeRAID controller can be installed and replaced without
tools. This means less time (and therefore less money) spent servicing the x3650 M2.
Additionally, hot-swap/redundant HDDs, fan modules and power supplies, as well as
online mirrored memory, mean greater system uptime while these components are being
• 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 3Gbps or 6 Gbps RAID controller to enhance system availability and data
protection without using a PCIe slot.
• 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.
• Altitude- and 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 warranty4 helps afford you peace of mind
and greater investment protection than a one-year warranty does.
Key Features
High-Performance Xeon 5500 Series Processors
The x3650 M2 supports up to two high-performance Intel Xeon 5500 Series processors, allowing
you to upgrade to a second processor as your business needs require. The x3650 M2 offers a
choice of processor clock rates, memory access speeds and energy draw, including:
• 95W four-core Xeon models X5550, X5560, or X5570 running at 2.66, 2.8, or 293GHz,
respectively, with impressive performance/watt (23.75W per core; 6.4Gtbps QPI speed), 8MB
of L3 processor cache, 1333MHz memory access, and Intel Turbo Boost technology
• 60W four-core Xeon low-voltage models or L5530* running at 2.26GHz or 2.4GHz,
respectively, with low power draw and impressive performance/watt (only 15W per core;
5.86Gtps QPI speed), and 8MB of shared L3 cache, 1066MHz memory access, and Intel
Turbo Boost technology
• 80W four-core Xeon models E5520, E5530, or E5540 running at 2.26, 2.4, or 2.53GHz,
respectively, with reduced power draw and impressive performance/watt (only 20W per core;
5.86Gtps QPI speed), 8MB of L3 processor cache, 1066MHz memory access, and Intel Turbo
Boost technology
• 60W four-core Xeon low-voltage model L5506 running at 2.13GHz, with low power draw and
impressive performance/watt (only 15W per core; 4.8Gtps QPI speed), 4MB of L3 processor
cache, and 800MHz memory access
• 80W four-core Xeon models E5504 or E5506 running at 2.0 or 2.13GHz, respectively, with
reduced power draw and impressive performance/watt (only 20W per core; 4.8Gtps QPI
speed), 4MB of L3 processor cache, and 800MHz memory access
• 80W two-core Xeon model E5502 running at 1.86GHz, with reduced power draw (40W per
core; 4.8Gtps QPI speed), 4MB of L3 processor cache and 800MHz memory access
With the Xeon 5500 Series processors, Intel has diverged from its traditional Symmetric
Multiprocessing (SMP) architecture to a Non-Uniform Memory Access (NUMA) architecture. The
Xeon 5500 processors are connected through a serial coherency link called QuickPath
Interconnect (QPI). QPI is capable of 6.4, 5.6 or 4.8 GT/s (gigatransfers per second), depending
on the processor model.
Two-core Xeon processors contain two complete processor cores; four-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 two-core processors offer considerably higher
performance than a same-speed Xeon processor with a single core. Likewise, four-core
processors offer considerably higher performance than a same-speed Xeon processor with dual
Turbo Boost Technology dynamically turns off unused processor cores and increases the clock
speed of the cores in use, by up to two model frequencies. For example, with three cores active,
a 2.26GHz processor can run the cores at 2.4GHz. With only one or two cores active, the same
processor can run those cores at 2.53GHz. Similarly, a 2.93GHz processor can run at 3.06GHz
or even 3.33GHz. When the cores are needed again, they are dynamically turned back on and
the processor frequency is adjusted accordingly.
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.
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-3 Registered Memory with Chipkill ECC Protection
The x3650 M2 ships with registered double data rate III (DDR-3) memory and provides Active
Memory features, including advanced Chipkill memory protection (optionally), for up to 16X
better error correction than standard ECC memory. In addition to offering better performance than
DDR-2 or fully-buffered memory, DDR-3 memory also uses less energy. DDR-2 memory already
offered up to 37% lower energy use than fully buffered memory. Now, a generation later, DDR-3
memory is even more efficient, using 22% less energy than DDR-2 memory.
The x3650 M2 supports up to 128GB of memory in sixteen DIMM slots. Redesign in the
architecture of the Xeon 5500 series processors bring radical changes in the way memory works
in these servers. For example, the Xeon 5500 series processor integrates the memory
controller inside the processor, resulting in two memory controllers in a 2-socket system. Each
memory controller has three memory channels. Depending on the type of memory, population of
memory, and processor model, the memory may be clocked at 1333MHz, 1066MHz or 800MHz.

1-16: DIMM population sequence; D1-D16: DIMM slot assignments
Note: If only one processor is installed, only the first eight DIMM slots can be used. Adding a
second processor not only doubles the amount of memory available for use, but also doubles the
number of memory controllers, thus doubling the system memory bandwidth. If you add a second
processor, but no additional memory for the second processor, the second processor has to
access the memory from the first processor “remotely,” resulting in longer latencies and lower
performance. The latency to access remote memory is almost 75% higher than local memory
access. So, the goal should be to always populate both processors with memory.
The X55xx models support up to 1333MHz memory clock speed, while the E55xx-and-up and
L55xx-and-up models support up to 1066MHz clock speed, and the E550x models support

800MHz clock speed.. Using 1333MHz memory (where supported) versus 1066MHz offers up to
9% better performance, while 1066MHz memory produces up to 28% better performance than
800MHz memory.
Xeon 5550 series processors access memory with almost 50% lower latency than the previous
generation 5400 series processors. That can result in faster processing of latency-sensitive
This new processor design comes with some trade-offs in memory capacity, performance, and
cost: For example, greater memory capacity comes with lower memory speed. Alternatively, it
is possible to achieve the same memory capacity at lower cost but at a lower memory speed.
Regardless of memory speed, the Xeon 5500 platform represents a significant improvement in
memory bandwidth over the previous Xeon 5400 platform. At 1333MHz, the improvement is
almost 500% over the previous generation. This huge improvement is mainly due to the dual
integrated memory controllers and faster DDR-3 1333MHz memory. Throughput at 800MHz is 25
gigabytes per second (GBps); at 1066MHz it’s 32GBps; and at 1333MHz it’s 35GBps. This
improvement translates into improved application performance and scalability.
Memory interleaving refers to how physical memory is interleaved across the physical DIMMs. A
balanced system provides the best interleaving. A Xeon 5500 processor-based system is
balanced when all memory channels on a socket have the same amount of memory.
A memory rank is simply a segment of memory that is addressed by a specific address bit.
DIMMs typically have 1, 2 or 4 memory ranks, as indicated by their size designation.
• A typical memory DIMM description is 2GB 4Rx8 DIMM
• The 4R designator is the rank count for this particular DIMM (R for rank = 4)
• The x8 designator is the data width of the rank
It is important to ensure that DIMMs with appropriate number of ranks are populated in each
channel for optimal performance. Whenever possible, it is recommended to use dual-rank
DIMMs in the system. Dual-rank DIMMs offer better interleaving and hence better performance
than single-rank DIMMs. For instance, a system populated with six 2GB dual-rank DIMMs
outperforms a system populated with six 2GB single-rank DIMMs by 7% for SPECjbb2005. Dualrank DIMMs are also better than quad-rank DIMMs because quad-rank DIMMs will cause the
memory speed to be down-clocked.
Another important guideline is to populate equivalent ranks per channel. For instance, mixing
one single-rank DIMM and one dual-rank DIMM in a channel should be avoided.
Note: It is important to ensure that all three memory channels in each processor are populated.
The relative memory bandwidth decreases as the number of channels populated decreases. This
is because the bandwidth of all the memory channels is utilized to support the capability of the
processor. So, as the channels are decreased, the burden to support the requisite bandwidth is
increased on the remaining channels, causing them to become a bottleneck.
For increased availability, the x3650 M2 offers an additional (but mutually exclusive) level of IBM
Active Memory protection: online memory mirroring..
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. One-half of total memory is available for use
with mirroring enabled. (Note: Due to the double writes to memory, performance is affected.)
Mirroring is handled at the hardware level; no operating system support is required.
DDR-3 memory is available in 1GB, 2GB, 4GB and 8GB DIMMs. DIMMs are installed individually
(not in pairs).
Drive Bays
The x3650 M2 contains twelve drive bays in all. Hot-swap drives may be inserted or removed
through the front of the server without powering off the system. Simple-swap solid-state 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.

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 PCIe adapter offers approximately eight
times the maximum throughput of a 133MHz PCI-X adapter7. (A x1 adapter offers throughput
similar to a 66MHz PCI-X slot.)
There is a built-in riser card in the x3650 M2 that provides a PCIe connector (physical x8
connector wired with x4 lanes) for an internal ServeRAID card.
Dual-Port Gigabit Ethernet Controller
The x3650 M2 includes one dual-port integrated Broadcom 5709C Gigabit Ethernet controller
standard, 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. There is no additional
charge for this capability.
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
Integrated quad Gb Ethernet ports:
• Up to four (4) Gb Ethernet ports, ideal for virtualization and I/O-intensive workloads
• 2 ports standard, plus two additional ports via optional daughtercard
• Improves system performance by offloading protocol processing from CPU to a separate TOE
• Primary performance improvement for data copying (CPU) where CPU utilization is 90-100%
• The embedded NIC/TOE supports software iSCSI using a Microsoft iSCSI initiator
• Using a software initiator enables offloading the processing of TCP frames with the TOE
engine in the adapter card, but the processing of iSCSI packets themselves is not hardwareoffloaded at the Broadcom NIC
• Broadcom hardware-offloaded iSCSI (using TOE engine) of the iSCSI frames
• iSCSI and RDMA are not supported on this server
Two Broadcom 5709 Gigabit Ethernet controllers (one on-board and one on an optional daughter
card) provide four Gigabit ports supporting IEEE 802.3 for 1000Base-T, 100Base-TX, and
10Base-T applications (802.3, 802.3u, 802.3ab) through a RJ-45 connector to an Ethernet
network over a CAT 5 twisted-pair cable. This controller supports PXE 2.0 remote boot, TOE, and
jumbo frames (9KB). A license key is required to enable the iSCSI and RDMA features. TOE
support on Windows is available today, but requires the Windows Scalable Network Pack (SNP)
installed. Linux has no plan to support TOE at this time. Please refer to TOE_RDMA_iSCSI.doc
for technology details. Internet Protocol version 6 (IPv6) is supported.
Ultra-Efficient Cooling
Strategically located fans, combined with efficient airflow paths, provide highly effective system
cooling for the x3650 M2, known as Calibrated Vectored Cooling. The base server with one
power supply includes three hot-swap fan modules, for redundant cooling. Each pack includes
two back-to-back fans with counter-rotating blades for a total of 3 fan modules. In addition, each
Please see the Legal Information section for important notices and information.
Leadership enterprise server with significantly lower cost of ownership in a highly available and
expandable, rack-dense, 2U dual-socket server
power supply also contains a fan.
The system contains three cooling zones. Zone 1 (incorporating one fan pack) cools all 16
DIMM sockets, Zone 2 (one fan pack) cools the primary processor, and Zone 3 (one fan pack)
cools the second processor.
The fans automatically adjust speeds in response to changing thermal requirements 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. In addition, the Bosch BMP085
altimeter works in conjunction with IMM to govern fan rotation. At high altitudes the air is thinner
and doesn’t cool as well as at lower elevations. In most servers, the fans run fast all the time to
allow for use at high elevations, wasting power. The altimeter allows the IBM fans to run at lower
speeds at lower altitudes.
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.
There are temperature sensors on the planar placed to sense DIMM exhaust temperature, SAS
HDD exhaust temperature, and CPU2 exhaust temperature (through the altimeter).
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 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 Chipkill protection, and memory mirroring enabled)
• Hot-swap, redundant hard disk drives (with RAID protection)
• Hot-swap, redundant power supplies
• Hot-swap, redundant cooling fan modules
Other Features
• Five 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, two on the
back, plus one USB connector reserved for an internal USB flash memory key containing an
embedded hypervisor. For pre-boot and normal drive use, use the external ports.
• Embedded hypervisor (via USB connector on the motherboard) — Activated with an optional
2GB USB key for supporting VMWare ESXi for virtualization.
• Virtual Media Key — This optional full-function systems management adapter adds local and
remote management functions without consuming a valuable adapter slot.
• Dual video ports — A Matrox G200eV SVGA video controller provides up to 1024x768
resolution, with a color depth of 32 bits at 85Hz refresh rate. To simplify local systems
management, one video port is provided on the front of the unit and one on the back.
• Toolless slides — Allows quick rack installation and quicker upgrade and servicing of the
Please see the Legal Information section for important notices and information.
Leadership enterprise server with significantly lower cost of ownership in a highly available and
expandable, rack-dense, 2U dual-socket server
• Toolless chassis — The cover can be opened without tools, and many components can be
removed and replaced without tools, including the CD-RW/DVD combo drive, hot-swap drives,
and PCIe adapters, as well as the integrated ServeRAID card, embedded hypervisor key, and
Virtual Media Key. 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%.
The illustration below shows a sample ACT configuration:
Via Daisy-Chain
• Max.16 servers per port
All CAT5, 5e, 6
Via Secondary
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.
Extensive System Support Features
The IBM services and technical support portfolio provides world-class, consistent, high-quality
service and support. The x3650 M2 server offers a number of tools and services designed to

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 you total cost of ownership and the complexity that
administrators and technical personnel face.
IBM Systems Director Service and Support Manager (previously called 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 service8
if necessary to those customers entitled to onsite support under the terms of their warranty or an
IBM Maintenance Agreement. Service and Support Manager 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

services to provide the level of expertise you require.
Advanced Systems Management Capabilities
The x3650 M2 has a high level of systems management capabilities that are well-suited to
remote locations as well as to stand-alone environments. Features include UEFI, IMM, Tool
Center, IBM Systems Director Active Energy Manager, Automatic Server Restart, Wake on LAN®
support, PXE support, text console redirect, Predictive Failure Analysis, IBM Systems Director
and support for an optional Remote Supervisor Adapter II SlimLine.
The Integrated Management Module (IMM) provides industry-standard Intelligent Platform
Management Interface (IPMI) 2.0-compliant systems management. It provides a number of

• Other mandatory and optional IPMI IMM functions
The IMM alerts IBM Systems Director to anomalous environmental factors, such as voltage and
thermal conditions—even if the server has failed.
The x3650 M2 also supports an optional IBM Virtual Media Key for additional systems
management capabilities, including:
• 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 to put control of system powersaving 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 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 x3650 M2 text
messages over serial or LAN. An optional upgrade to the Virtual Media Key adds graphical
console redirection.
Predictive Failure Analysis (PFA) is designed to allow the system to detect impending failure of
supported components (processors, memory, HDDs, voltage regulator modules (VRMs), power
supplies, 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
x3650 M2. IBM Systems Director comes with a portfolio of tools, including IBM Systems
Director Active Energy Manager™, Service and Support Manager, and others. System
Availability (a no-charge download) and Capacity Manager (sold separately) are available as addons 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 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, two or four cores, 64-bit
Please see the Legal Information section for important notices and information.
Leadership enterprise server with significantly lower cost of ownership in a highly available and
expandable, rack-dense, 2U dual-socket server
extensions, a large cache and advanced features for availability and manageability. Large cache
size, combined with fast 1333MHz, 1066MHz or 800MHz memory access and an integrated
memory controller reduce memory latency and facilitates the movement of data. (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 4-core processor, there should be twice as
much memory available as for a 2-core processor.
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
M2 with capacities of 500GB (2.5-inch) at 7,200 RPMs and 146.8GB (2.5-inch) at 15,000 RPMs.
2.5-inch SATA HDDs are available in capacities up to 500GB (2.5-inch) at 7,200 RPMs.
Solid State Drives — IBM solid-state drives offer high performance and the ultimate in reliability,
with 3X the MTBF (mean time between failure) rate of enterprise HDDs. IBM SSDs. are available
in 50GB capacities. They can be used as a highly available boot drive, for storing disk images, or
for other uses that stress read performance.
Power Supply — The optional second power supply for the x3650 M2 enables redundancy for
hot-swap power. In addition, its 92%-efficient design helps lower your energy bill for power and
Virtual Media Key — The x3650 M2 includes a plethora of systems management features builtin; however, sometimes additional management capability is needed. In those situations, the
Virtual Media Key not only offers powerful new features, it does so without taking up a valuable
PCI-X or PCIe adapter slot, instead using a dedicated connector on the motherboard.
ServeRAID Controllers — System x servers using ServeRAID 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.
External Storage — The IBM System Storage DS3000, DS4000, DS6000, and DS8000 series,
as well as the 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 System Storage EXP3000 storage enclosure.
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

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.
