Flex System X6 Compute Node (7903)

The Flex System X6 Compute Node, machine type 7903, is a high-performance scalable compute node that is designed to take on the most demanding workloads. The performance, flexibility, and resiliency features enable the X6 to run mission-critical workloads, such as key business applications, database, analytics, and large virtual machine deployments.

The X6 Compute Node family is composed of the x880 X6, x480 X6, and x280 X6. Each compute node contains two Intel Xeon E7 processors. The x880 X6 uses E7-8800 v2 processors and supports joining two or four x880 compute nodes together to form a single 8-socket server with 192 DIMM slots. The x480 uses E7-4800 v2 processors and supports joining two x480 compute nodes together to form a single 4-socket server with 96 DIMM slots. The x280 has two E7-2800 v2 processors and 48 DIMM slots but does not offer scaling.

Suggested use: Mission-critical scalable databases, business analytics, virtualization, enterprise applications, and cloud applications.

Figure 1 shows the Flex System X6 Compute Node.

If you are using an application that requires significant computing power and you value the integration of components that Flex System offers, then the X6 Compute Node family is an excellent choice. It offers the performance and reliability of the Intel Xeon E7 processor family, plus significant memory and I/O capacity, and lets you easily scale from two sockets all the way to eight sockets by simply adding more compute nodes and using the appropriate scalability connector on the front of the server.

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 and 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 into the Flex System ecosystem with the announcement of the Flex System X6 family of compute nodes. Like their rack-mount counterparts, the System x3850 X6 and x3950 X6, Flex System X6 Compute Nodes are fast, agile, and resilient:

• Fast application performance means immediate access to information.
• Agile system design helps reduce acquisition costs and provides 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

Each compute node offers numerous features to boost performance:

• Based on the Intel Xeon processor E7 v2 product family, which improves productivity by offering superior system performance:
  • Two processors in each compute node, which are scalable up to eight processors in four compute nodes.
  • Each processor has up to 15 cores and 37.5 MB of L3 cache, depending on the processor that is selected.
  • Processors operate at up to 3.4 GHz.
  • Memory bus speeds up to 1600 MHz.
  • QPI links between processors up to 8 GTps.
• Supports up to 48 DIMM sockets, with 24 DIMMs per processor.
• 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.
• The usage of solid-state drives (SSDs) instead of traditional hard disk 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 v2 product families. This integration helps reduce I/O latency and increase overall system performance.

Agile system design

The X6 Compute Nodes provides many scalability and flexibility features:

• Innovative front-access scalable design where a customer can start with one x880 X6 Compute Node with two sockets and simply add more processing power by inserting additional compute nodes into the chassis (up to a total of four, depending on the processor selection) and mounting a scalability connector to the front of all the compute nodes.
• The usage of front-access scalability connectors means that you can easily scale the X6 system by adding new compute nodes without removing existing compute nodes from the chassis.
• With the usage of E7-8800 v2 processors, upgrading from a 2-socket (one compute node) to 4-socket (two compute nodes) to 8-socket (four compute nodes) complex is as simple as inserting the extra compute nodes and attaching the appropriate scalability connector to the front of all the compute nodes. No tools are required. The usage of E7-4800 v2 processors allows an upgrade from a 2-socket (one compute node) to 4-socket (two compute nodes) complex in the same way.
• The usage of compute nodes as modular building blocks 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.
• Using 64 GB LRDIMMs, each compute node supports up to 3 TB of memory and up to 6 TB in a scaled complex.
• Offers 4 PCIe 3.0 I/O slots per compute node, and up to 16 slots in an 8-socket scaled complex.

Resilient platform

The server provides many features to simplify serviceability and increase system uptime:

• 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.
• The Intel Execute Disable Bit function can help prevent certain classes of malicious buffer overflow attacks when it is 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.
• Flex System Enterprise Chassis-based hot-swap power supplies and hot-swap dual-motor redundant fans provide availability for mission-critical applications.
• A light path diagnostics panel and individual light path LEDs quickly lead the technician to failed (or failing) components. This panel 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 recovery actions in case of failures to minimize downtime.
• 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 functions, such as digital signatures and remote attestation.
• Industry-standard Advanced Encryption Standard (AES) NI support for faster and stronger encryption.
• IBM Flex System Manager provides proactive systems management. It offers comprehensive systems management tools that help increase uptime, reduce costs, and improve productivity through advanced server management capabilities.
• Built-in diagnostic tests, using Dynamic Systems Analysis (DSA) Preboot, speed up troubleshooting tasks to reduce service time.
• Three-year customer-replaceable unit and onsite limited warranty, 9x5 next business day. Optional service upgrades are available.

Figure 3. Inside view of the Flex System X6 Compute Node

The following figure shows how four x880 Compute Nodes can be connected together to form a single 8-socket complex. Note this is for illustrative purposes only; in a production environment, you first install the compute nodes in the chassis and then attach the scalability connector to all four nodes.

Figure 4. Four x880 X6 Compute Nodes in an 8-socket complex

The following table lists the standard specifications.

The X6 Compute Nodes are shipped with the following items:

• Statement of Limited Warranty
• Important Notices
• Documentation CD that contains the Installation and Service Guide

The following table lists the standard models. Currently, the x480 X6 is available as a standard model. The x280 X6 and x880 X6 are available configure-to-order only.

Table 2. Standard models

** Processor detail: Processor quantity and model, cores, core speed, L3 cache, memory speed, and power consumption.
‡ For models D2x, the standard DIMM is rated at 1600 MHz, but operates at 1333 MHz to match the processor memory speed.

The X6 Compute Nodes are supported in the Flex System Enterprise Chassis as listed in the following table:

Table 3. Chassis support

Up to seven X6 compute nodes can be installed in the chassis in 10U of rack space. The number of scaled systems that can be installed is as follows:

• Two-socket systems: Up to seven systems in an Enterprise Chassis
• Four-socket systems: Up to three systems in an Enterprise Chassis
• Eight-socket systems: One system in an Enterprise Chassis

It might also be possible to populate the remaining bays within the chassis with other standard or double-wide nodes. The actual number of servers that can be installed in a chassis also depends on these factors:

• The TDP power rating for the processors that are installed in the server
• The number of power supplies that are installed
• The capacity of the power supplies that are installed (2100 W or 2500 W)
• The power redundancy policy that is used (N+1 or N+N)

The following table provides guidelines about what number of X6 Compute Nodes can be installed. For more information, use the Power Configurator, found at the following website:
http://ibm.com/systems/bladecenter/resources/powerconfig.html

In the table:

• Green = No restriction to the number of X6 Compute Nodes that are installable.
• Yellow = Some bays must be left empty in the chassis.

Table 4. Maximum number of X6 Compute Nodes that are installable based on the power supplies that are installed and the power redundancy policy that is used

The X6 compute nodes can scale to a 4-socket or 8-socket complex depending on the processor that is installed into the node:

• An x880 X6 node with Intel Xeon E7-8800 v2 family processors can scale up to an 8-socket configuration, and supports 2-socket, 4-socket, and 8-socket configurations. All the processors in these 2-socket, 4-socket, and 8-socket configurations must be identical.
• An x480 X6 node with Intel Xeon E7-4800 v2 family processors can scale up to a 4-socket configuration, and supports 2-socket and 4-socket configurations. All the processors in these 2-socket and 4-socket configurations must be identical.
• An x280 X6 node with Intel Xeon E7-2800 v2 family processors supports only 2-socket configurations. The processors in 2-socket configurations must be identical.

The scaled X6 compute nodes are connected together through a front interconnect system. The interconnection has a QPI bus plus the sideband signals that are needed for correct operation.

There are two scalability connector assemblies for X6 nodes, as shown in the following table.

Table 5. Scalability options for X6 compute nodes

The following figure shows the Flex System x880 X6 4-Socket Scalability Connector and how it is used to connect two X6 servers together (x880 or x480).

Figure 5. Flex System x880 X6 4-Socket Scalability Connector

The X6 compute nodes support the processor options that are listed in the following table. The server supports two Intel Xeon E7-2800 v2, E7-4800 v2, or E7-8800 v2 processors depending on model. The table also shows which server models have each processor standard. If no corresponding model for a particular processor is listed, the processor is available only through the configure-to-order (CTO) process.

No part numbers: All Flex System X6 Compute Nodes have two processors as a standard. There is no option part number for processors, only feature codes.

Table 6. Processor options

* The first feature code is for CPU 1 and the second feature code is for CPU 2.
† The processors support two memory modes: RAS mode (also known as lockstep mode) and Performance mode (also known as independent mode). In Performance mode, the SMI2 link operates at twice the memory bus speed that is shown.

Lenovo DDR3 memory is compatibility tested and tuned for optimal performance and throughput. Lenovo memory specifications are integrated into the light path diagnostic tests for immediate system performance feedback and optimum system uptime. From a service and support standpoint, Lenovo memory automatically assumes the system warranty.

The X6 Compute Nodes support DDR3 memory operating at speeds up to 1600 MHz with 24 DIMMs per processor:

• A 2-socket configuration supports up to 48 DIMMs.
• A 4-socket scaled configuration supports up to 96 DIMMs.
• An 8-socket configuration supports up to 192 DIMMs.

The following table lists the memory options that are available for X6 Compute Nodes.

Table 7. Memory options

Each processor has four memory channels to memory buffers that are implemented using Scalable Memory Interface generation 2 (SMI2) chips. Each memory buffer has two memory channels and implements three DIMMs per channel.

The following rules apply when selecting the memory configuration:

• The X6 node supports RDIMMs and LRDIMMs.
• LR-DIMMs and RDIMMs cannot be mixed within a single compute node or a scaled complex.
• Mixing 1.5 V and 1.35 V DIMMs in the same server is supported. In such a case, all DIMMs operate at 1.5 V.
• The processors support two memory modes: Performance mode and RAS (or lockstep) mode. In RAS (lockstep) mode, DIMMs must be installed in a pair, and the SMI link operates at the speed of the memory bus.
• When RDIMMs are installed, the maximum number of ranks that are supported per channel is eight. With LRDIMMs, the rank count per channel can be 32 (LRDIMM ranks are only 25% of the electrical load of an RDIMM rank).
• All DIMMs in all processor memory channels operate at the same speed, which is determined as the lowest value of the following components:
  • The memory mode used: Performance (independent) mode or RAS (lockstep) mode.
  • Memory speed that is supported by a specific processor.
  • Lowest of maximum operating speeds for selected memory configuration, depending on the rated speed, operating voltage, and quantity of DIMMs per channel, as shown under the “Maximum operating speed” section in the following table.

The following table shows the characteristics of the supported DIMMs. Tables cells that are highlighted with a gray background indicate that the server supports higher memory frequencies or larger memory capacity (or both) than the Intel processor specification defines.

Memory speed: In performance mode, memory channels operate independently, and the SMI2 link operates at twice the DDR3 speed. In RAS mode, two channels operate synchronously, and the SMI2 link operates at the DDR3 speed.

Table 8. Maximum memory speeds

* Maximum quantity that is supported is shown for all the processors that are 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.

The X6 compute node has two 2.5-inch front-accessible hot-swap drive bays that are accessible from the front of the server. These bays are connected to the integrated ServeRAID M1210e controller.

The ServeRAID M1210e controller includes the following features:

• Based on the LSI SAS 3004 12 Gbps SAS/SATA RAID-on-Chip (ROC) controller
• Four-port controller with 12 Gbps throughput per port
• PCIe x4 Gen 2 host interface
• Supports RAID levels 0, 1, 10, and 1E; optionally supports RAID 5 and RAID 50.

RAID 5 and RAID 50 are supported through a Features on Demand upgrade, as shown in the following table. For 4-socket and 8-socket complexes, one FoD upgrade is required for each SAS controller on which you want to enable RAID 5.

Table 9. ServeRAID M1210e upgrades

Supported drives are listed in the "Internal drive options" section.

Note: The X6 Compute Node, machine type 7903, does not support 1.8-inch drives nor the ServeRAID M5115.

The 2.5-inch drive bays support SAS or SATA HDDs or SATA SSDs. The following table lists the supported 2.5-inch drive options.

The server does not support an internal tape drive. However, it can be attached to external tape drives by using Fibre Channel connectivity.

The server does not support an internal optical drive option, however, you can connect an external USB optical drive. See http://support.lenovo.com/en/documents/pd011281 for information about available external optical drives from Lenovo. Alternatively, use the remote media feature of the IMMv2 and the Chassis Management Module.

Note: The USB port on the compute node supplies up to 0.5 A at 5 V. For devices that require more power, an additional power source is required.

The X6 compute node has four I/O expansion connectors for attaching I/O adapters, as shown in the following figure. Installing I/O adapters allows the server to connect to switch modules in the Flex System Enterprise Chassis. The following figure shows the location of the four I/O expansion slots.

Note: Slots 3 and 4 support only a subset of the adapters that are supported in slots 1 and 2. Slots 3 and 4 do not support dual-ASIC adapters because of the PCIe lanes that are routed to slots 3 and 4. For specifics, see the "Network adapters" section.

Figure 6. Location of the I/O adapter slots in the X6 Compute Node

A compatible switch or pass-through module must be installed in the corresponding I/O bays in the chassis, as indicated in the following table. Installing two switches means that all the ports of the adapter are enabled, which improves performance and network availability.

Table 11. Adapter to I/O bay correspondence

For a list of supported switches, see the Flex System Interoperability Guide, available from:
http://lenovopress.com/fsig

Server power is derived from the power supplies that are installed in the chassis. There are no server options regarding power supplies.

The X6 compute node supports the ESXi hypervisor on a USB memory key through two internal USB ports (see Figure 3). The supported USB memory keys are listed in the following table.

There are two types of USB keys: preinstalled keys or blank keys. Blank keys allow you to download a customized version of ESXi and load it onto the key. The compute node supports one or two keys installed, but only certain combinations:

Supported combinations:

• One preinstalled key
• One blank key
• One preinstalled key and one blank key
• Two blank keys

Unsupported combinations:

• Two preinstalled keys

Installing two preinstalled keys prevents ESXi from booting, as described at http://kb.vmware.com/kb/1035107. Having two keys that are installed provides a backup boot device. Both devices are listed in the boot menu, which allows you to boot from either device or to set one as a backup in case the first one becomes corrupted.

The supported USB memory keys are listed in the following table.

Table 14. Virtualization options

For quick problem determination when you are physically at the server, the compute node offers a 3-step guided path:

1. The Fault LED on the front panel
2. The light path diagnostics panel
3. LEDs next to key components on the system board

The light path diagnostics panel is visible when you remove the server from the chassis. The panel is at the upper right side of the compute node, as shown in the following figure.

Figure 9. Location of X6 light path diagnostics panel

To illuminate the light path diagnostics LEDs, power off the compute node, slide it out of the chassis, and press the power button. The power button doubles as the light path diagnostics remind button when the server is removed from the chassis. The meanings of the LEDs are listed in the following table.

Table 15. Light path diagnostic panel LEDs

The server contains an Integrated Management Module II (IMM2), which interfaces with the advanced management module in the chassis. The combination of these two components provides advanced service-processor control, monitoring, and an alerting function. If an environmental condition exceeds a threshold or if a system component fails, LEDs on the system board are lit to help you diagnose the problem, the error is recorded in the event log, and you are alerted to the problem. A virtual presence capability comes standard for remote server management.

Remote server management is provided 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 server also supports virtual media and remote control features, which provide the following functions:

• Remotely viewing video with graphics resolutions up to 1600x1200 at 75 Hz with up to 23 bits per pixel, regardless of the system state
• Remotely accessing the server 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 IMM2 memory and mapping it to the server as a virtual drive

• Hard Drive Retention

  Lenovo’s Hard Drive Retention service is a multi-drive hard drive retention offering that ensures your data is always under your control, regardless of the number of hard drives that are installed in your Lenovo server. In the unlikely event of a hard drive failure, you retain possession of your hard drive while Lenovo replaces the failed drive part. Your data stays safely on your premises, in your hands. The Hard Drive Retention service can be purchased in convenient bundles with our warranty upgrades and extensions.

• Microcode Support

  Keeping microcode current helps prevent hardware failures and security exposure. There are two levels of service: analysis of the installed base and analysis and update where required. Offerings vary by country and can be bundled with other warranty upgrades and extensions.

• Remote Technical Support Services (RTS)

  RTS provides comprehensive technical call center support for covered servers, storage, operating systems, and applications. Providing a single source for support of hardware and software issues, RTS can reduce problem resolution time, decreasing the cost to address technical problems and increasing uptime. Offerings are available for Windows, Linux, IBM Systems Director, VMware, Microsoft business applications, and Lenovo System x storage devices, and IBM OEM storage devices.
