Did you know?

The x3950 X6 server employs a lid-less design where all serviceable components are front- and rear-accessible. In addition, each major subsystem is implemented as modular "book" design, such as the Compute Books and I/O Books. This configuration means that components are easy to upgrade and service, which translates to greater uptime of applications to your users. The x3950 X6 offers enterprise scalability and advanced RAS features to support the most demanding mission-critical applications that require 24x7 operations.

Key features

The increasing demand for cloud-computing and analytics workloads by enterprises to meet social, mobile, and Big Data requirements drives innovation to find new ways to build informational systems. Clients are looking for cost-optimized fit-for-purpose IT solutions that manage large amounts of data, easily scale performance, and provide enterprise class reliability.

Built on decades of innovation, Lenovo introduces its sixth generation of Enterprise X-Architecture technology, X6 servers. Lenovo X6 servers are fast, agile, and resilient:

  • Fast application performance means immediate access to actionable information.
  • Agile system design helps to reduce acquisition costs and provide the ability to upgrade processor and memory technology at each refresh within the same chassis.
  • Resilient platforms maximize application uptime and promote easy integration in virtual environments.

X6 servers continue to lead the way as the shift toward mission-critical scalable databases, business analytics, virtualization, enterprise applications, and cloud-computing applications accelerates.

Fast application performance

The server offer numerous features to boost performance:
  • With eXFlash memory-channel storage, the server delivers up to 12.8 TB of ultra-low latency flash memory by using WriteNow technology, which is ideal for high-performance applications.
  • Supports four, six, or eight E7-8800 v2 processors with 120 cores and 240 threads to maximize the concurrent running of multi-threaded applications.
  • Supports memory speeds up to 1600 MHz.
  • Supports up to 12 TB of memory in 192 DIMM sockets, with 24 DIMMs per processor.
  • Supports memory-channel storage (eXFlash DIMMs), where solid-state storage devices are installed in memory DIMM sockets. These devices are directly connected to the processors and provide the lowest latency values in the industry.
  • Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows processor cores to run at maximum speeds during peak workloads by temporarily going beyond processor thermal design power (TDP).
  • Intel Hyper-Threading Technology boosts performance for multi-threaded applications by enabling simultaneous multi-threading within each processor core, up to two threads per core.
  • Intel Virtualization Technology integrates hardware-level virtualization hooks that allow operating system vendors to better use the hardware for virtualization workloads.
  • Intel Advanced Vector Extensions (AVX) improve floating-point performance for compute-intensive technical and scientific applications.
  • Supports a 12 Gbps SAS RAID portfolio.
  • The usage of solid-state drives (SSDs) instead of, or along with, traditional spinning drives (HDDs) can improve I/O performance. An SSD can support up to 100 times more I/O operations per second (IOPS) than a typical HDD.
  • PCI Express 3.0 I/O adapter slots that improve the theoretical maximum bandwidth by almost 100% (8 GTps per link using 128b/130b encoding) compared to the previous generation of PCI Express 2.0 (5 GTps per link using 8b/10b encoding).
  • With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon processor E7-4800/8800 v2 product families. This integration helps reduce I/O latency and increase overall system performance.
  • Support for up to four graphics processing units (GPUs) and co-processors to maximize computing power.
  • Energy-efficient electronic components help lower operational costs, including highly efficient 900 W AC and 1400 W AC power supplies with 80 PLUS Platinum certification.


Agile system design

The server provides many scalability and flexibility features:
  • Innovative module "book" design for each of the three subsystems: Compute Books, Storage Book, and I/O Books. Front and rear access means that you can easily scale the system by adding components without removing the entire server from the rack.
  • The modular book design also allows clients to create the configuration that fits their application and environment needs, which reduces acquisition costs while giving them the flexibility to grow and modify their configuration later.
  • The book design also means that subsystem upgrades are simpler, quicker to perform, and have a lower impact on the rest of the server.
  • Using 64 GB LRDIMMs, the server supports up to 12 TB of memory.
  • Up to 32 eXFlash DIMMs are supported for a total of 12.8 TB of low-latency and high-performance storage.
  • Up to 32x 1.8-inch eXFlash SSD bays, or up to 16x 2.5-inch bays, provide a flexible and scalable all-in-one platform to meet your increasing demands.
  • Offers up to 22 PCIe slots plus two dedicated Mezzanine LOM (ML2) adapter slots. Most slots are PCIe 3.0 to maximize I/O scalability.
  • PCIe slots are implemented in I/O Books to maximize modularity. Choose from Half-length I/O Books or Full-length I/O Books, depending on the adapters that you need to deploy.
  • Most components are common between the four-socket x3850 X6 and eight-socket x3950 X6, making for a simple upgrade path with minimal parts on the floor.


Resilient platform

The server provides many features to simplify serviceability and increase system uptime:
  • Upward Integration Modules for standard hypervisors enable the creation and management of policies to maintain high availability of virtual machines and concurrent updating of the system firmware, with no impact on application performance or availability.
  • Advanced Processor Recovery allows the system to automatically switch access and control of networking, management, and storage in the event of a processor 1 failure, providing higher availability and productivity.
  • Advanced Page Retire proactively protects applications from corrupted pages in memory, which is crucial for scaling memory to terabytes.
  • Redundant bit steering, memory mirroring, and memory rank sparing for redundancy in the event of a non-correctable memory failure.
  • Intel Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow attacks when combined with a supported operating system.
  • Intel Trusted Execution Technology provides enhanced security through hardware-based resistance to malicious software attacks, allowing an application to run in its own isolated space, which is protected from all other software running on a system.
  • Redundant Intel Platform Controller Hub (PCH) connections to the processors allow the platform to maintain access to networking, storage, and server management during a processor failure.
  • Hot-swap drives support RAID redundancy for data protection and greater system uptime.
  • Hot-swap I/O Books enabling you to install or replace adapters while the server is still running.
  • Tool-less lid-less design provides front and rear access for easy upgrades and serviceability. There is no need to pull the server out of the rack to access internal components.
  • Hot-swap power supplies and hot-swap dual-motor redundant fans provide availability for mission-critical applications.
  • A new LCD diagnostics panel that is combined with individual light path diagnostic 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, memory, HDDs, SSDs, fans, and power supplies) operate outside of standard thresholds and generates proactive alerts in advance of a possible failure, therefore increasing uptime.
  • Built-in Integrated Management Module Version II (IMM2) continuously monitors system parameters, triggers alerts, and performs recovering actions in case of failures to minimize downtime.
  • Includes two special Mezzanine LOM (ML2) adapter slots with support for adapters with either two 10 Gb ports or 4 Gb ports. Supports direct connectivity to the IMM2 service processor for out-of-band systems management.
  • Integrated industry-standard Unified Extensible Firmware Interface (UEFI) enables improved setup, configuration, and updates, and simplifies error handling.
  • Two integrated Trusted Platform Modules (TPMs) 1.2 support enables advanced cryptographic functionality, such as digital signatures and remote attestation.
  • Industry-standard Advanced Encryption Standard (AES) NI support for faster and stronger encryption.
  • IBM Systems Director® provides proactive systems management. It offers comprehensive systems management tools that help increase uptime, reduce costs, and improve productivity through advanced server management capabilities.
  • Solid-state drives (SSDs) offer better reliability than traditional mechanical HDDs for greater uptime.

* Maximum quantity supported is shown for all processors installed.

The following memory protection technologies are supported:
  • ECC
  • Chipkill (for x4-based memory DIMMs)
  • Redundant bit steering (Double Device Data Correction)
  • Memory mirroring
  • Memory rank sparing

Chipkill and Redundant Bit Steering are supported in RAS mode. Chipkill is supported in Performance mode.

If memory mirroring is used, DIMMs must be installed in pairs for Performance mode (minimum of one pair per each processor) and quads for RAS mode. DIMMs in the pair/quad must be identical in type and size.

If memory rank sparing is used, then a minimum of two single-rank or dual-rank DIMMs must be installed per populated channel (the DIMMs do not need being identical). In rank sparing mode, one rank of a DIMM in each populated channel is reserved as spare memory. The size of a rank varies depending on the DIMMs that are installed.

eXFlash memory-channel storage

eXFlash memory-channel storage are storage offerings in the physical form of memory DIMMs. These eXFlash DIMMs are installed in memory DIMM sockets but appear to the operating system and applications as block storage devices. This new and innovative technology brings storage electrically closer to the processor subsystem, therefore improving performance considerably.

Note: Both the x3850 X6 and the x3950 X6 support at most 32 eXFlash DIMMs.

The following table shows the supported eXFlash DIMMs.

Figure 5. eXFlash DIMM installed in the Compute Book

The following rules apply when building a server configuration with eXFlash DIMMs:
  • The 200 GB and 400 GB eXFlash DIMMs cannot be mixed.
  • Performance memory mode must be selected. RAS (lockstep) memory mode is not supported.
  • Only RDIMMs are supported by eXFlash DIMMs; LRDIMMs are not supported
  • eXFlash DIMMs can only installed on the Compute Books in the lower half of the server (processors 1-4)
  • The maximum quantities of eXFlash DIMMs are as follows:
    • Four processors: 16 eXFlash DIMMs
    • Six processors: 24 eXFlash DIMMs
    • Eight processors: 32 eXFlash DIMMs

I/O expansion options

The server supports up to 22 PCIe slots plus two dedicated Mezzanine LOM slots (24 total) as follows:

  • In each of the two Storage Books (standard in all models): Two PCIe 3.0 x8 slots for supported internal RAID controllers and SAS HBAs
  • In each of the two Primary I/O Books (standard in all models):
    • Two PCIe 3.0 x16 slots (x16-wired), half length, full height, up to 75 W of power
    • One PCIe 3.0 x16 (x8-wired), half length, full height, up to 75 W of power
    • One mezzanine LOM 2 (ML2) slot for network adapters with the new ML2 form factor (PCIe 3.0 x8)
  • Four optional I/O Books, each with three slots, all full height. Optional I/O Books are hot-swap capable.

The following figure shows the Primary I/O Book with the air baffle raised to show the internals.

Primary I/O Book
Figure 8. Primary I/O Book

Optional I/O Books can be either of:
  • Half-length I/O Book:
    • Two PCIe 3.0 x8 slots (x8 wired)
    • One PCIe 3.0 x16 slot (x16 wired)
  • Full-length I/O Book:
    • Two PCIe 3.0 x16 (x16 wired)
    • One PCIe 2.0 x8 slot (x4 wired)

In order for an I/O Book to be hot-swappable, all adapters that are installed in the book must support hot-swap and the operating system must also support hot-swap. These operating systems support hot-swap:
  • Windows Server 2008 R2
  • Windows Server 2012
  • Windows Server 2012 R2

The following figure shows the Half-length I/O Book.

Half-length I/O Book
Figure 10. Half-length I/O Book

Each slot in the Half-length I/O Book and the Full-length I/O Book supplies up to 75 W of power.

The Full-length I/O Book also includes two auxiliary power connectors. With the usage of these connectors and the supplied power cords, the I/O book supports one double-wide adapter up to 300 W. The auxiliary power connectors are as follows:
  • One 2x4 power connector, which supplies up to 150 W of additional power to the adapter
  • One 2x3 power connector, which supplies up to 75 W of additional power to the adapter

The combined power consumption of all the adapters that are installed in the Full-length I/O Book cannot exceed 300 W.

Note: The 2x3 connector is intended to be used only when one adapter is installed in the first x16 slot (the up-most slot in the following figure), either requiring 225 W or 300 W of power. The location of the 2x3 connector prevents an adapter from being installed in the other x16 slot.

Full-length I/O Book
Figure 11. Full-length I/O Book

The Half-length I/O Book installs flush with the Primary I/O Book at the rear of the server. The Full-length I/O Book, when installed, adds a 99 mm (3.9 in.) mechanical extension to the base length dimension of the chassis.

The following figure shows a Full-length I/O Book and a Half-length I/O Book installed in the server.

GPU adapters

The server supports the co-processors and graphics processing units (GPUs) that are listed in the following table. Each is installed in a Full-length I/O Book. No other adapter can be installed in the Full-length I/O Book. The Full-length I/O Book includes the necessary auxiliary power cables.

Notes:

  • These adapters are not available through CTO and cannot be shipped installed in the server because they are installed in the Full-length I/O Book, which extends beyond the rear of the chassis (see Figure 12). These adapters must be shipped separately from the server. Order the adapter and Full-length I/O Book as separate options.
  • If a NVIDIA Grid K1, Grid K2, Tesla K20c, Tesla K40, Quadro K4000 or Quadro K6000 is installed, the maximum system memory that can be installed is 1 TB.

Systems management

The server contains Integrated Management Module II (IMM2), which provides advanced service-processor control, monitoring, and an alerting function. If an environmental condition exceeds a threshold or if a system component fails, the IMM2 lights LEDs to help you diagnose the problem, records the error in the event log, and alerts you to the problem. The IMM2 also provides a virtual presence capability for remote server management capabilities.

The IMM2 provides remote server management through industry-standard interfaces:

  • Intelligent Platform Management Interface (IPMI) Version 2.0
  • Simple Network Management Protocol (SNMP) Version 3
  • Common Information Model (CIM)
  • Web browser

The remote presence provides the following functions:
  • Remotely viewing video with graphics resolutions up to 1600 x 1200 at 75 Hz with up to 23 bits per pixel colors, regardless of the system state
  • Remotely accessing the server by using the keyboard and mouse from a remote client
  • Mapping the CD or DVD drive, diskette drive, and USB flash drive on a remote client, and mapping ISO and diskette image files as virtual drives that are available for use by the server
  • Uploading a diskette image to the IMM memory and mapping it to the server as a virtual drive

The blue-screen capture feature captures the video display contents before the IMM restarts the server when the IMM detects an operating-system hang condition. A system administrator can use the blue-screen capture feature to assist in determining the cause of the hang condition.

Supported operating systems

The server supports the following operating systems:

  • Microsoft Windows Server 2008 R2
  • Microsoft Windows Server 2012
  • Microsoft Windows Server 2012 R2
  • Red Hat Enterprise Linux 6 Server x64 Edition
  • Red Hat Enterprise Linux 7
