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.

Lenovo eX5 technology represents the fifth generation of enterprise servers based on the same design

principle that 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.

Seven PCIe 2.0 slots for maximum I/O expandability
