Outstanding performance, superior mainframe-like  
reliability, and fault-tolerant memory characteristics  
Architecture  
Overview  
IBM® has been designing and implementing chipsets under the X-Architecturename since  
2001. eX4 technology represents the fourth generation of products based on the same design  
principle IBM began with in 1997: to offer systems that are expandable, offer “big iron” reliability,  
availability, and serviceability (RAS) features, with extremely competitive price/performance on  
an Intel® Xeon® processor-based system.

The eX4 technology is primarily designed around three major workloads. These workloads are  
database servers, server consolidation using virtualization services, and Enterprise Resource  
Planning (application and database) servers.

If you are adopting industry-standard Xeon EM64T servers for running business critical  
applications, the systems that run these applications need the type of technology designed into  
IBM’s eX4 technology systems. The eX4 chipset represents a $100M+ investment in designing  
a flagship offering that can harness the power of 4-socket-and-up 64-bit x86 (x64) Xeon  
processors. The eX4 design includes two 4U 4-socket rack-optimized chassis (x3850 M2 and  
x3950 M2) with the ability to scale up to 16 sockets and up to 96 cores. In fact, you can start  
with a single-node x3850 M2 chassis, and by adding a ScaleXpander Option Kit, you can turn  
it into an x3950 M2, ready to expand into a multi-node configuration providing more flexibility in  
deploying your scalable solution than ever before.

The x3850 M2 now offers selected models integrated with VMware ESXi 3.5 preloaded on an  
IBM 4GB USB 2.0 Flash Key. It operates in a diskless configuration, offers a smaller memory  
footprint, extremely high performance, and stronger security, making getting a system up and  
running in a virtualized environment faster and easier than ever before.  
IBM X-Architecture pioneered XpandOnDemand(“pay as you grow”) scalability, which allows  
chassis to be simply cabled together to form larger scale-up systems. This unique capability  
allows IBM to sell a large SMP (symmetric multiprocessing) system at entry price points. Other  
Intel OEMs can’t match this capability. If they offer a 16-socket product at all, they require you to  
start out with a 16-socket chassis, whether you’ll ever grow into it or not. With  
XpandOnDemand, you can start small, with a 4- or 8-socket configuration, and later expand as  
your needs change, without requiring you to buy more than you need up-front or throw away  
parts later as you expand.  
IBM’s eX4 technology-based systems are the ideal solution for scale-up database-serving  
applications on Microsoft® Windows® with Microsoft SQL Server® or IBM DB2®, as well as Linux®  
with Oracle 9i RAC and 10g, or IBM DB2. Database hosting demands ultimate server reliability  
features, and once installed, they grow and grow. The eX4 design offers two strong selling  
arguments against the competition: lower initial purchase price, and potentially much lower long-  
term TCO.  
Another strong application area for the eX4-based systems is enterprise server consolidation  
activities. Larger servers have more processor, memory and I/O resources, which make  
maximum use of any applicable virtual machine software licensing fees and deliver superior  
system utilization levels. The name of the game in consolidation activities is to deploy the fewest  
new servers possible and help IT staff manage more images with the same or fewer overall  
people.  
One of the fastest growing application areas for eX4-based systems is ERP workloads, including  
SAP and Oracle. eX4-based systems can offer considerable savings over UNIX deployments,  
using our certified solution stacks on either Windows or Linux.  
The 4-socket eX4 servers are designed to protect your data with high performance, high  
reliability, and high availability. They support the latest six-, quad- and dual-core Intel® Xeon™  
processors, designed with high-performance quad 1066MHz front-side buses (FSB), 64-bit  
extensions (EM64T), and either 8MB (dual-core); 4MB, 6MB, or 8MB (quad-core); or 9MB of  
L2 cache; 8MB, 12MB or 16MB (six-core) of L3 cache, and up to 256MB of L4 cache per  
chassis (all models), to help provide you with the computing power you need to match your

Combining high-performance architecture with high-performance Xeon processors  
IBM System x3950 M2-specific  
ScaleXpander Option Kit standard  
Offers physical partitioning at four-socket granularity allowing you to run multiple  
operating systems on the same integrated hardware  
Support for up to two ServeRAID-MR10k options if a multi-chassis configuration is used  
Key Features  
High-Performance Xeon Processors  
The x3850 M2 and x3950 M2 ship with two high-performance Intel Xeon processors, and  
support up to four, allowing you to upgrade as business needs require. The eX4 servers also go  
a step further by allowing you to add additional nodes (chassis) to increase the number of  
sockets from 4 to as many as 16 (using four total chassis). (The ScaleXpander Option Kit  
converts a 4-socket x3850 M2 into an ultra-expandable x3950 M2.) With multiple chassis, you  
can use physical partitioning to segment the one physical server into multiple logical servers for  
virtualization.  
Processors can be added or replaced through the top cover of the system. The system offers a  
choice of processor clock rates, FSB speeds and power draw:  
130W six-core Xeon processor model X7460 at 2.67GHz, with 64-bit extensions, low power  
draw per core (21.67W), quad 1066MHz FSBs, 9MB of L2 processor cache (3 x 3MB; 1.5MB  
per core), and 16MB of shared L3 cache  
130W quad-core Xeon processor model X7350 at 2.93GHz, with 64-bit extensions, 32.5W  
per core of power draw, quad 1066MHz FSBs, and 8MB of L2 cache (2 x 4MB; 2MB per  
core)  
90W six-core Xeon processor model E7450 at 2.4GHz, with 64-bit extensions, extremely low  
power draw per core (15W), quad 1066MHz FSBs, 9MB of L2 processor cache (3 x 3MB;  
1.5MB per core), and 12MB of shared L3 cache  
90W quad-core Xeon processor model E7420 at 2.13GHz, with 64-bit extensions, low power  
draw per core (22.5W), quad 1066MHz FSBs, 9MB of L2 processor cache (3 x 3MB; 1.5MB  
per core), and 8MB of shared L3 cache  
80W quad-core Xeon processor model E7330 at 2.4GHz, with 64-bit extensions, low power  
draw per core (20W), quad 1066MHz FSBs, and 6MB of L2 cache (2 x 3MB; 1.5MB per core)  
80W quad-core Xeon processor models E7320 at 2.13GHz, with 64-bit extensions, low  
power draw per core (20W), quad 1066MHz FSBs, and 4MB of L2 cache (2 x 2MB; 1MB per  
core)  
80W dual-core Xeon processor model E7210 at 2.4GHz, with 64-bit extensions, 40W per  
core of power draw, quad 1066MHz FSBs, and 8MB of L2 cache (2 x 4MB; 4MB per core)  
50W quad-core Xeon processor model L7445 at 2.13GHz, with 64-bit extensions, extremely  
low power draw per core (12.5W), quad 1066MHz FSBs, 9MB of L2 processor cache (3 x  
3MB; 1.5MB per core), and 12MB of L3 cache  
Also available via special bid/configure-to-order:  
90W quad-core Xeon processor model E7440 at 2.4GHz, with 64-bit extensions, extremely  
low power draw per core (15W), quad 1066MHz FSBs, 9MB of L2 processor cache (3 x  
3MB; 1.5MB per core), and 16MB of shared L3 cache  
90W quad-core Xeon processor model E7430 at 2.13GHz, with 64-bit extensions, extremely  
low power draw per core (12.5W), quad 1066MHz FSBs, 9MB of L2 processor cache (3 x  
3MB; 1.5MB per core), and 12MB of shared L3 cache  
65W six-core Xeon processor model L7455 at 2.13GHz, with 64-bit extensions, extremely  
low power draw per core (10.83W), quad 1066MHz FSBs, 9MB of L2 processor cache (3 x  
3MB; 1.5MB per core), and 12MB of shared L3 cache  
The dual-core Xeon processors contain two complete processor cores. Each processor  
contains two 4MB L2 caches, 4MB per core (8MB total per processor). The two cores appear  
to software as separate physical processors. The dual-core processors can offer more than  
double the performance of a same-speed single-core Xeon processor (depending on workload).  
Similarly, quad-core Xeon processors contain four processor cores. The cores share dual  
2MB, 3MB, or 4MB L2 caches (4MB, 6MB, or 8MB total per processor). That is, two cores per  
L2 cache. They can offer more than double the performance of dual-core Xeon processors  
(again, depending on workload). The six-core processors contain six processor cores. The  
cores share dual 4MB, 6MB, or 8MB L2 caches (8MB, 12MB, or 16MB total per processor).  
The servers provide four separate 1066MHz FSBs (front-side buses), one per processor. Each  
of the four FSBs (which connect memory and I/O to the processor) boasts a peak rate of  
8.53GBps (34.1GBps aggregate).This contrasts to the two 667MHz FSBs (with up to two  
processors per FSB) provided in the original x3850/x3950 models. In other words, you now have

twice as many FSBs as before and each is 60% faster than before.  
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 32-  
bit 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. Customers should contact their software  
provider to determine their software support for EM64T.  
Intel’s Virtualization Technology (VT) integrates hardware-level virtualization hooks that allow  
operating system vendors to better utilize the hardware for virtualization workloads, a key  
workload for the eX4 platform.

eX4 Chipset ‘Snoop’ Filtering  
1066 MT/s  
One of the core features of the eX4 chipset that gives the platform a performance advantage is  
the snoop filter. The Xeon Coherency Protocol or “snoop” is an operation that occurs whenever  
a processor in an SMP system needs to update a memory address during normal operation.  
The snoop occurs when the processor getting ready to operate on a piece of data asks the other  
processors in the SMP complex to verify they have not modified the same piece of data without  
writing back from their cache. This operation increases traffic on the front side bus.

The eX4 chipset contains 324MB of EDRAM within the Northbridge chip. This copies all data as  
it is written to the processor cache, allowing the chipset to respond directly to the snoop  
requests. This reduces the overall traffic across the FSB and helps to improve system  
performance over other architectures. (Intel now offers a first-generation snoop filter in their  
7300 chipset; however it contains only 64MB of RAM which is 80% smaller than the eX4 fourth-  
generation solution.)

Advanced Buffer eXecution  
The IBM Advanced Buffer  
eXecution (ABX) chips (2 per  
chassis) provide the x3850 M2 /  
3950 M2’s DDR2 memory with  
up to 60% more bandwidth than  
other vendors can manage using  
more expensive (and more  
energy-hungry) Fully Buffered  
DIMMs (FB-DIMMs). The ABX  
chip uses two buffers per  
memory card to re-drive the  
signals from the eX4 memory  
controller to the DIMMs,  
bypassing the latency-adding  
buffers used on each FB-DIMM.  
The use of ABX reduces  
latency by 20% vs. FB-DIMMs.  
This feature is a unique IBM  
enhancement, not offered by  
other x86 server architectures  
(using either Intel or AMD processors).  
XceL4v Dynamic Server Cache  
Another performance feature of the eX4 chipset is the XceL4v L4 cache. When using a single  
node (chassis), the cache works with the snoop filter to help reduce FSB traffic. When more  
than one node is used, 256MB of virtual cache per node (taken from main memory) is used for  
interprocessor communications between chassis, to keep data in synch. In a 4chassis  
configuration, this amounts to as much as 1GB of L4 cache. This not only compensates for any  
performance hit that might otherwise result from sending data across the distances between  
processors in multiple chassis, it actually results in a performance improvement versus a single  
chassis. (IBM X3 and eX4 servers have achieved well over 100 #1 results on industry-standard  
benchmarks, such as TPC-C, TPC-E, TPC-H, SAP SD, vConsolidate, Vmark, and more.)  
This feature is a unique IBM enhancement, not offered by other x86 server architectures (using  
either Intel or AMD processors).

Combining high-performance architecture with high-performance Xeon processors  
High-Speed Scalability Ports  
When more than one chassis is used, they are simply cabled together via one or more  
scalability cables. Up to three cables connected to low-latency, 10.24Gbps full-duplex ports  
(5.12Gbps in each direction), supported by up to 1GB of L4 cache, provide exceptional  
interchassis throughput (30.72Gbps aggregate). Because of this design, an x3950 M2 server  
has the incredible flexibility of starting out as a 4-socket server with up to 256GB of memory,  
256MB of L4 cache, seven PCIe adapter slots, and four HDD bays, and then doubling, tripling,  
or even quadrupling those numbers while maintaining first-in-class performance.  
This feature is another unique IBM enhancement, not offered by other x86 server architectures.  
DDR II ECC Memory with Active Memory Protection  
The eX4 servers support up to 256GB of memory per node (chassis) in 32 DIMM sockets (up to  
1TB for a 4-node/16-processor configuration). It uses PC5300 double data rate II (DDR II)  
memory (operating at 533MHz) for faster access, and provides IBM Active Memory features,  
including advanced IBM Chipkill memory protection, for up to 16X better error correction than  
standard ECC memory, IBM Memory ProteXion, hot-add/hot-swap memory support, and  
optional memory mirroring. (Notes: Hot-add capability requires operating system support. Hot-  
add memory and mirroring are mutually exclusive. Conversely, hot-swap requires mirroring.)  
The standard configuration includes two memory cards, which support up to eight DIMMs  
apiece. The system is upgradeable to four memory cards with eight DIMMs each. With  
configurations of 8-to-16 DIMMs, using two memory cards saves cost, but using four cards  
increases performance. (With more than 16 DIMMs, four memory cards are required.)  
The memory architecture of the eX4 chipset provides up to 60% more aggregate memory  
bandwidth (up to 34.1GBps when using four memory cards vs. a maximum of 21.3GBps  
bandwidth in the previous generation), for exceptional memory performance, and quadruple the  
system memory capacity of the predecessor x3850 server. 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. Even running at 533Mhz, with twice the number of channels and twice the DIMM  
capacity supported, the x3850 M2 and x3950 M2 deliver a memory subsystem with greater  
throughput than the competition. In addition, the DDR2 DIMMs use up to 37% less energy than  
the competition’s FB-DIMMs.  
Memory scrubbing is an automatic daily test of all system memory. It detects and reports  
memory errors that might be developing before they cause a server outage. Memory scrubbing  
and Memory ProteXion work together. When a bit error is detected, memory scrubbing  
determines whether the error is recoverable. If the error is recoverable Memory ProteXion  
technology will write the data to new location; if it is not recoverable, scrubbing sends an alert to  
light path diagnostics, which then notifies IBM Systems Director.  
Memory ProteXion technology (also called redundant bit steering) provides multichip error  
protection and works in conjunction with Chipkill technology—which provides multibit protection  
per chip—and standard ECC protection, to provide three-level memory correction. For increased  
availability, the eX4 design offers an additional level of Active Memory protection: 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. Note: Mirroring requires  
DIMMs to be installed in multiples of four (one pair per memory channel).  
A secondary benefit of memory mirroring is that the failed DIMM and its memory card can be  
hot-swapped out to replace the failed DIMM. This is a hardware feature that is operating system  
independent.  
DIMMs must be installed in matching pairs. Memory is available in kits consisting of two 1GB,  
2GB, 4GB or 8GB DIMMs.  
Flexible Internal Storage Capacity  
The eX4 servers offer a choice of internal storage, supporting up to four (2.5-inch) hot-swap  
high-performance Serial-Attach SCSI (SAS) drives per chassis. In addition, selected models of  
the x3850 M2 include an integrated 4GB USB 2.0 Flash Key with VMware preloaded as an  
embedded virtualization hypervisor.

2.5-inch SAS  
10,000 RPMs — 73.4 or 146.8GB (587.2GB maximum per chassis; 2.349TB in a 4-chassis  
configuration)  
15,000 RPMs — 73.4GB (293.6GB per chassis; 1.174TB per 4 chassis)  
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.  
The hot-swap SAS drives use the Converged Tray for interchangeability with other IBM System  
xsystems. If you need more storage space, terabyte capacities are possible with external  
direct-attach NAS and SAN solutions.  
Integrated Virtualization  
Selected models of the x3850 M2 ship with an IBM 4GB USB 2.0 Flash Key installed preloaded  
with VMware ESXi 3.5. This is an embedded version of VMware ESX 3.5, fully contained on the  
flash drive and requiring no disk space—not an “ESX Lite.” Rather than management through a  
Service Console based on a Linux operating system, ESXi 3.5 relies on aggregate management  
tools, including VirtualCenter, the Remote Command Line interface and the introduction of CIM  
for standards-based and agentless hardware monitoring.  
VMware ESXi 3.5 includes all the performance, scalability and compatibility features of ESX 3.5,  
including full VMFS support across FC SAN, iSCSI SAN, and NAS, and 4-way VSMP. Because  
it runs from flash memory, it’s extremely fast and ideal for diskless configurations. It also offers  
enhanced security, because it runs without an operating system-based console and is  
updated/patched much like firmware. Licensing works the same as for “standard” ESX 3.5.  
If you prefer Microsoft Hyper-Vto VMware, the intent is for the x3850 M2 and x3950 M2 to  
fully support Microsoft’s hypervisor software installed on the system HDD at a future date.  
Disk/Tape Controllers  
All models include an integrated eight-port LSI 1078 Serial-Attach SCSI (SAS) controller. This  
controller supports up to four internal SAS LVD (low-voltage differential) drives.  
The integrated SAS controller offers hardware RAID-0/1 support for those SAS drives. The  
ServeRAID-MR10k option adds additional RAID levels, including RAID-10, 5, 50, 6 and 60,  
along with 256MB of battery-backed cache memory for higher performance and data integrity,  
without consuming a valuable PCIe adapter slot.  
The SAS controller provides data transfer speeds of up to 300MB per second1 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.  
Additional external SAS/SATA disk storage, as well as tape backup, is available using the  
external SAS port on the system unit, or via one of several supported iSCSI or FC SAN  
controllers.  
Drive Bays  
The eX4 servers contain five drive bays (per chassis) in all—including four 2.5-inch HDD bays  
that support hot-swap SAS drives totaling up to 587.6GB.  
A 24X/10X/24X/8X2 speed (ultraslim, 0.5”) CD-RW/DVD-ROM combo drive with an IDE  
interface ships standard in all x3850 M2 and x3950 M2 servers. No floppy drive is supplied with  
any model; an external USB floppy drive may be used, if needed.  
For still more storage, a direct-attach, iSCSI, or FC SAN external expansion option can be  
added, using an optional controller.  
High-Performance Adapter Slots  
There are seven physical x8 (“by 8”) PCIe (PCI Express) adapter slots standard (per chassis).  
Each is capable of supporting x4 or x8 adapters. All slots are half-length/full-height.  
Electrically they are x8 slots as well (meaning that they operate at full x8 4GBps speeds). Slots  
6 and 7 are Active PCIe hot-add/hot-swap slots, offering the capability to add or replace  
adapters without having to shut down the system.  
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 PCIe adapter offers approximately four  
1 Data transfer rates depend on many factors and are often less than the maximum possible.

Combining high-performance architecture with high-performance Xeon processors  
times the maximum throughput of a 133MHz PCI-X adapter3. (A x1 adapter offers throughput  
similar to a 66MHz PCI-X slot.)  
Because the SAS, ServeRAID-MR10k, dual Gigabit Ethernet, and systems management  
controllers are integrated onto the system board, the seven adapter slots are all available, which  
offers you a wide degree of latitude in expansion options.  
(Even though the HP DL580G5 has eleven total slots, they offer lower throughput, providing no  
more aggregate bandwidth than the seven slots of the eX4 servers.)  
Dual Gigabit Ethernet Controller  
The eX4 systems include one integrated dual-port Broadcom 5709C Gigabit Ethernet  
controller, with TOE (TCP Offload Engine) acceleration support (available 1Q/08), as well as  
load-balancing and failover capabilities between the two ports.  
TOE support helps improve overall system performance by offloading TCP/IP protocol  
processing from the system microprocessor to the onboard Ethernet TOE processor. iSCSI  
support works similarly for iSCSI workloads.  
The controller 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.  
Ultra-Efficient Cooling  
Six strategically located hot-swap/redundant fans, combined with efficient airflow paths,  
provide highly effective system cooling for the eX4 systems, known as Calibrated Vectored  
Cooling. The fans are arranged to cool three separate zones, left, center, and right, with one  
pair of redundant fans per zone.  
The fans automatically adjust speeds in response to changing thermal requirements, depending  
on the zone, redundancy, 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 if you  
have a larger number of systems the aggregate savings in power and noise pressure can be  
significant.  
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:  
Hot-add/hot-swap redundant memory protection (with Chipkill, Memory ProteXion,  
and selectable memory mirroring capabilities)  
Hot-swap redundant hard disk drives (with standard LSI 1078 controller and optional  
ServeRAID-MR10k providing multiple levels of RAID support)  
Hot-swap PCIe adapter slots (with optional failover support)  
Hot-swap redundant cooling fans (three redundant pairs)  
Hot-swap redundant power supplies4  
Light Path Diagnostics  
Light path diagnostics enables a technician to quickly identify and locate a failed or failing  
system component, such as a specific memory DIMM. (Monitored components include  
processors, memory, power supplies, fans, HDDs, adapters, and voltage regulator modules  
(VRMs), plus system temperature.) 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 all processors,  
all adapter slots, all fans, all power supplies, all voltage regulator modules 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.)  
In addition to the outstanding diagnostic detection, there is a new feature with a digital readout  
that indicates at what stage of the boot process your system may have experienced trouble.  
This can reduce the troubleshooting time and help get your system up and running quickly and  
efficiently.  
Other Features  
Trusted Platform Module standard — This module provides a highly secure start-up  
process from power-on through hand-off to the operating system boot loader. ACPI support is  
provided to allow ACPI-enabled operating systems to access the security features of this  
module. (TCG V1.2-compliant.)  
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, three are  
on the back, and one is internal to support the embedded 4GB USB 2.0 Flash Memory Key  
in selected models.  
Remote Supervisor Adapter II standard — This full-function systems management adapter  
provides local and remote management functions in a dedicated PCI-X slot, without  
consuming one of the seven PCIe adapter slots.  
Video — An ATI Radeon ES1000 SVGA video controller on the Remote Supervisor Adapter  
II provides up to 1024x768 resolution, with a color depth of 32 bits at 85Hz refresh rate, with  
16MB of video memory.  
Toolless slides — Allows quick rack installation and quicker upgrade and servicing of the  
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-add/hot-  
swap memory, hot-swap HDDs, adapters, and the integrated optional ServeRAID-MR10k  
and Remote Supervisor Adapter II. 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  
daisy-chain 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.  
The illustration below shows a sample ACT configuration:

Advanced Systems Management Capabilities  
The x3850 M2 and x3950 M2 have a high level of systems management capabilities that are  
well-suited to remote locations as well as to stand-alone environments. Features include the  
Baseboard Management Controller (BMC), IBM Systems Director Active Energy Manager for  
x86 (formerly known as PowerExecutive), Automatic Server Restart, Wake on LAN® support,  
PXE support, text console redirect, Predictive Failure Analysis, IBM Systems Director, IBM  
Systems Director Active Energy Manager for x86, and the Remote Supervisor Adapter II.  
The BMC provides industry-standard Intelligent Platform Management Interface (IPMI) 2.0-  
compliant 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  
Fan speed control  
Product ID and Family ID detection  
Highly secure remote power on/off  
System reset control  
NMI/SMI detection and generation  
System diagnostic LED control (power, HDD, activity, alerts, heartbeat)  
IPMI over LAN  
Serial Over LAN  
Proxy server support  
LAN messaging and alerting  
Text console redirection over LAN  
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 IBM Remote Supervisor Adapter II provides additional systems management capabilities,  
including:  
Graphical console redirection over LAN

SSL (Secure Socket Layer) and LDAP (Lightweight Directory Access Protocol) support  
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  
low-level 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 and Graphical Console Redirection support allows the administrator to remotely view  
system text messages and graphics over serial or LAN.  
Predictive Failure Analysis (PFA) is designed to allow the x3850 M2/x3950 M2 to detect  
impending failure of supported components (processors, memory, PCIe slots, VRMs, power  
supplies, fans, and hard disk drives) 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 eX4  
servers. IBM Systems Director comes with a portfolio of tools, including Management Processor  
Assistant, Rack Manager, RAID Manager, Update Assistant and Software Distribution. IBM  
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.  
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 a  
combination of hardware and software 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.  
Extensive System Support Features  
The IBM services and technical support portfolio provides world-class, consistent, high-quality  
service and support. The eX4 servers offers a number of tools and services designed to make  
ownership a positive experience. From the start, IBM programs make it easier for you 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 IBM  
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.  
The IBM ServerProven program provides the confidence that specific options and operating  
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)  
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

Combining high-performance architecture with high-performance Xeon processors  
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 your total cost of ownership and the complexity that  
administrators and technical personnel face.  
IBM Electronic Service Agentis 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 service5 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 provide 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 Intel Xeon processor provides high clock rates, a choice of dual-, quad-, or  
six cores, 64-bit extensions, a large cache and advanced features for availability and  
manageability. Large cache size, combined with a fast 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, third, or fourth  
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 server using single-core processors. A server with six-core  
processors should have three times as much memory as a server using dual-core processors.  
The eX4 servers take memory upgrades in pairs and provide two-way interleaving.  
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. 2.5-inch SAS hard disk drives are available for the  
eX4 servers with capacities up to 146.8GB apiece at 10,000 RPMs, or up to 73.4GB apiece at  
15,000 RPM.  
Remote Supervisor Adapter II — The x3850 M2 and x3950 M2 include a plethora of systems  
management features built-in. The Remote Supervisor Adapter II not only offers powerful new  
features, it does so without taking up a valuable PCIe adapter slot, instead using a dedicated  
PCI-X slot 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.  
5 For onsite labor, IBM will attempt to diagnose and resolve the problem remotely before sending a technician.

Combining high-performance architecture with high-performance Xeon processors  
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 integrated ServeRAID-MR10k SAS/SATA controller offers enhanced performance  
over the integrated LSI 1078 SAS controller, 256MB of battery-backed cache memory, and  
supports seven RAID levels: 0 (striping), 1 (mirroring), 10 (mirroring and striping), 5 (striping  
with parity), and 6 (striping with double parity), 50 (striping with parity across multiple arrays)  
and 60 (striping with double parity across multiple arrays). Note: RAID-50 and -60 require  
external storage, due to the minimum requirement of six or eight drives, respectively.  
External SAN, NAS and direct-attach storage is available using one of several IBM System  
Storageand TotalStoragehost bus adapters.  
The IBM TotalStorage 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.

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.

of Intel Corporation or its subsidiaries in the United States and  
other countries.  
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.
