Key features
The x3850 X5 is a mission-critical 4U four-socket server, capable of expanding to up to 8 processor
sockets and 6 TB of memory in 10U of rack space. It offering outstanding performance, and superior
reliability and fault-tolerant memory characteristics.
IBM® has been designing and implementing servers under the X-Architecture® name since 2001. IBM
eX5 technology represents the fifth generation of enterprise servers 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.
Scalability and performance
The x3850 X5 offers numerous features to boost performance, improve scalability, and reduce costs:
The x3850 X5 supports up to four high-performance Intel Xeon E7 family allowing you to upgrade as
business needs require.
Scalable to eight processors by connecting two x3850 X5 servers together to form a single system
image.
Each x3850 X5 scalable to 2 TB of memory internally or 3 TB of memory with the addition of the
MAX5 V2 memory expansion unit. With two x3850 X5 servers each with MAX5 units, the total
available system memory is up to 6 TB.
Supports the Intel Xeon E7-2800, E7-4800 and E7-8800 families of high performance processors, up
to 10 cores each, offering superior system performance
Intel Turbo Boost Technology dynamically turns off unused processor cores and increases the clock
speed of the cores in use, by up to three model frequencies. For example, with 7-10 cores active, a
2.4 GHz E7-2870 10-core processor can run the cores at up to 2.53 GHz. With 5-6 cores active, it can
run those cores at 2.67 GHz; with only 1-4 cores active, it can run those cores at 2.8 GHz
Each processor includes two integrated memory controllers, to reduce memory bottlenecks and
improve performance. Memory access is at up to 1066 MHz frequency, depending on the processor
model and memory used.
The MAX5 V2 adds an additional four memory controllers for a total of eight memory controllers to
maximize memory parallelism and performance.
In processors implementing Hyper-Threading technology, each core has two threads capable of
running an independent process. Thus, an 8-core processor can run 16 threads concurrently.
Intel’s Virtualization Technology (VT) integrates hardware-level virtualization hooks that allow
operating system vendors to better utilize the hardware for virtualization workloads.
Intel QuickPath Interconnect (QPI) technology for processor-to-processor connectivity and Intel
Scalable Memory Interconnect (SMI) processor-to-memory connectivity:
Intel QPI link topology at up to 6.4 Gbps with four QPI links per CPU
Intel SMI link topology at up to 6.4 Gbps with four SMI links per CPU
Up to 64 DIMM sockets in the server (eight per memory card), plus an additional 32 DIMMs with an
optional 1U MAX5 V2 memory expansion unit, for a total of 96 DIMM sockets. With two x3850 X5
servers each with MAX5 units, the total number of DIMM sockets is 192.
The use of solid-state drives (SSDs) instead of, or along with, traditional spinning drives (HDDs) can
significantly improve I/O performance. An SSD can support up to 100 times more I/O operations per
second (IOPS) than a typical HDD.
Up to 24 1.8-inch SSD bays, or up to 16 2.5-inch bays together with the option of an optical drive,
provide a flexible and scalable all-in-one platform to meet your increasing demands.
IBM System x3850 X5 2
Seven PCIe 2.0 slots for maximum I/O expandability
Availability and serviceability
The x3850 X5 provides many features to simplify serviceability and increase system uptime:
Support for machine check architecture (MCA) recovery, a feature of the Intel Xeon processor E7
family, which enables the handling of system errors that otherwise require the operating system to be
halted. SAP HANA is one of the first application which leverages the MCA recovery to handle system
errors in order to prevent the application from being terminated in case of a system error.
Extensive memory protection with IBM Chipkill, and, with DIMMs containing x4 DRAM modules,
Redundant Bit Steering (RBS) (also known as Double Device Data Correction or DDDC) is also
supported . The combination of IBM Chipkill and RBS provides very robust memory protection that
sustains to two sequential memory DRAM chip failures without affecting overall system performance.
Redundant CPU-to-I/O hub interconnect links provide ability to self-recover from CPU failure. If
primary CPU fails then eX5 systems can use the second CPU to boot the OS as they still have
access to the integrated I/O devices because of redundant links between CPUs and I/O hubs.
Single image 8-way systems consisting of two interconnected 4-way nodes provide self-healing
capabilities in case of single node failure. Two independent nodes form a resilient 8-way
configuration. In case of single node failure the system can be restarted in degraded mode thus
eliminating unexpected downtime that requires service specialist to recover.
Memory mirroring and memory rank sparing for redundancy in the event of a non-correctable memory
failure.
Hot-swap drives, supporting RAID redundancy for data protection and greater system uptime.
Two 1975 W hot-swap power supplies and five fans (three hot-swap, two integrated into the power
supplies).
The power source independent light path diagnostics panel and individual light path LEDs quickly
lead the technician to failed (or failing) components, which simplifies servicing, speeds up problem
resolution, and helps improve system availability.
Predictive Failure Analysis (PFA) detects when system components (processors, VRMs, memory,
HDDs, fans, and power supplies) operate outside of standard thresholds and generates proactive
alerts in advance of a possible failure, therefore increasing uptime.
Solid-state drives (SSDs) offer significantly better reliability than traditional mechanical HDDs for
greater uptime.
Built-in Integrated Management Module (IMM) continuously monitors system parameters, triggers
alerts, and performs recovering actions in case of failures to minimize downtime.
Built-in diagnostics, using Dynamic Systems Analysis (DSA) Preboot, speed up troubleshooting tasks
to reduce service time.
Three-year customer-replaceable unit and on-site limited warranty, 9x5 next business day. Optional
service upgrades are available.
IBM System x3850 X5 3
Manageability and security
Powerful systems management features simplify local and remote management of the x3850 X5:
The server includes an Integrated Management Module (IMM) to monitor server availability and
perform remote management.
Integrated industry-standard Unified Extensible Firmware Interface (UEFI) enables improved setup,
configuration, and updates, and simplifies error handling.
Integrated Trusted Platform Module (TPM) 1.2 support enables advanced cryptographic functionality,
such as digital signatures and remote attestation.
IBM Systems Director is included for proactive systems management. It offers comprehensive
systems management tools that help to increase uptime, reduce costs, and improve productivity
through advanced server management capabilities.
Energy efficiency
The x3850 X5 offers the following energy-efficiency features to save energy, reduce operational costs,
increase energy availability, and contribute to the green environment:
Energy-efficient planar components help lower operational costs.
Support for one or two or four highly efficient 675 W ac power supplies allows for efficient use and
scalability to meet the power requirements of the installed components.
Intel Xeon processor E5-2600 product family offers significantly better performance over the previous
generation while fitting into the same thermal design power (TDP) limits.
Low-voltage Intel Xeon processors draw less energy to satisfy the demands of power and thermally
constrained data centers and telecommunication environments.
Low-voltage 1.35 V DDR3 memory RDIMMs consume 15% less energy compared to 1.5 V DDR3
RDIMMs.
Solid state drives (SSDs) consume as much as 80% less power than traditional spinning 2.5-inch
HDDs.
The server uses hexagonal ventilation holes, which is a part of IBM Calibrated Vectored Cooling™
technology. Hexagonal holes can be grouped more densely than round holes, providing more efficient
airflow through the system.
IBM Systems Director Active Energy Manager™ provides advanced data center power notification and
management to help achieve lower heat output and reduced cooling needs.

Memory options
IBM DDR3 memory is compatibility tested and tuned for optimal System x performance and throughput.
IBM memory specifications are integrated into the light path diagnostics for immediate system
performance feedback and optimum system uptime. From a service and support standpoint, IBM memory
automatically assumes the IBM system warranty, and IBM provides service and support worldwide.
The IBM System x3850 X5 supports DDR3 memory. Memory is installed in memory cards. The server
supports eight memory cards, and each card holds eight DIMMs. Two memory cards are connected to
each processor. As a result, all eight memory cards are usable only when all four processors are installed.
Adding a MAX5 memory expansion unit to the server offers an additional 32 DIMM slots for a total of 96
DIMM slots per node.
The following table lists the memory options that are supported in the server and MAX5 (either MAX5 V2
or MAX5).
Notes:
In the MAX5 memory expansion unit, do not mix DIMMs with x4 technology (DIMMs with DRAMs that
are organized with 4 data lanes, as indicated by "x4" in the description) with DIMMs with x8
technology (DIMMs with DRAMs that are organized with 8 data lanes).
In the server, you can mix DIMMs with x4 and x8 technology.
