  • The Intel Xeon Processor E5-2600 provides up to 80% performance boost over the previous generation, the Intel Xeon Processor 5600 (Westmere EP).
  • Up to two processors, 16 cores, and 32 threads maximize the concurrent execution of multi-threaded applications.
  • Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows CPU cores to run at maximum speeds during peak workloads by temporarily going beyond processor 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 utilize the hardware for virtualization workloads.
  • Intel Advanced Vector Extensions (AVT) significantly improve floating point performance for compute-intensive technical and scientific applications compared with Intel Xeon 5600 series processors.
  • Up to 24 DDR3 ECC memory RDIMMs provide speeds up to 1600 MHz and a memory capacity of up to 384 GB. Load-reduced DIMMs (LRDIMMs) are supported with a maximum capacity of 768 GB.
  • The theoretical maximum memory bandwidth of the Intel Xeon processor E5 family is 51.6 GBps, which is 60% more than in the previous generation of Intel Xeon processors.
  • 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.
  • Supports the Storage Expansion Node providing an additional 12 hot-swap 2.5-inch drive bays for local storage.
  • Up to 32 virtual I/O ports per compute node with integrated 10 Gb Ethernet ports, offering the choice of Ethernet, iSCSI, or Fibre Channel over Ethernet (FCoE) connectivity.
  • The x240 offers PCI Express 3.0 I/O expansion capabilities that improve the theoretical maximum bandwidth by 60% (8 GT/s per link), compared with the previous generation of PCI Express 2.0.
  • With Intel Integrated I/O Technology, the PCI Express 3.0 controller is integrated into the Intel Xeon processor E5 family. This helps to dramatically reduce I/O latency and increase overall system performance.
  • Support for high-bandwidth I/O adapters, up to two in each x240 Compute Node. Support for 10 Gb Ethernet, 16 Gb Fibre Channel, and FDR InfiniBand.
  • Supports the PCIe Expansion Node for support for up to six additional I/O adapters.

Availability and serviceability

The x240 provides many features to simplify serviceability and increase system uptime:

The x240 supports Low Profile (LP) DDR3 memory RDIMMs, UDIMMs, and LRDIMMs. The server supports up to 12 DIMMs when one processor is installed and up to 24 DIMMs when two processors are installed. Each processor has four memory channels, and there are three DIMMs per channel.

The following rules apply when selecting the memory configuration:

  • 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.
  • Mixing of different types of DIMMs (UDIMM , RDIMM and LRDIMM) in the same server is not supported.
  • The maximum number of ranks supported per channel is eight.
  • The maximum quantity of DIMMs that can be installed in the server depends on the number of CPUs, DIMM rank, and operating voltage, as shown in the "Max. qty supported" row in the following table. The shaded cells indicate that the DIMM type supports the maximum number of DIMMs (24 for the x240)
  • All DIMMs in all CPU memory channels operate at the same speed, which is determined as the lowest value of:
    • Memory speed supported by specific CPU
    • Lowest maximum operating speed for the selected memory configuration that depends on rated speed, as shown under the "Max. operating speed" section in the following table. The shaded cells indicate that the speed indicated is the maximum that the DIMM allows.

The following tables (Part 1 and Part 2) shows the maximum memory speeds that are achievable based on the installed DIMMs and the number of DIMMs per channel. The tables also show maximum memory capacity at any speed supported by the DIMM and maximum memory capacity at rated DIMM speed. In the tables, cells highlighted with a grey background indicate when the specific combination of DIMM voltage and number of DIMMs per channel still allows the DIMMs to operate at rated speed.

The following memory protection technologies are supported:

  • ECC
  • Chipkill (for x4-based memory DIMMs -- look for "x4" in the DIMM description)
  • Memory mirroring
  • Memory sparing

If memory mirroring is used, then DIMMs must be installed in pairs (minimum of one pair per CPU), and both DIMMs in a pair must be identical in type and size.

If memory rank sparing is used, then a minimum of one quad-rank DIMM or 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 installed.

Internal storage

The x240 server has two 2.5-inch hot-swap drive bays accessible from the front of the blade server (Figure 2). These bays connect to the integrated LSI SAS2004 6 Gbps SAS/SATA RAID-on-Chip (ROC) controller.

The integrated LSI SAS2004 ROC has the following features:

  • Four-port LSI SAS2004 controller with 6 Gbps throughput per port
  • PCIe x4 Gen 2 host interface
  • Two SAS ports routed internally to the two hot-swap drive bays
  • Supports RAID-0, RAID-1 and RAID-1E

The x240 also supports up to eight 1.8-inch drives with the addition of the ServeRAID M5115 controller and additional SSD tray hardware. These are described in the next section.

Supported drives are listed in the Internal drive options section.

ServeRAID M5115 SAS/SATA controller

The x240 supports up to eight 1.8-inch solid-state drives combined with a ServeRAID M5115 SAS/SATA controller (90Y4390). The M5115 attaches to the I/O adapter 1 connector and can be attached even if the Compute Node Fabric Connector is installed (used to route the Embedded 10Gb Virtual Fabric Adapter to bays 1 and 2, as discussed in "I/O expansion options"). The ServeRAID M5115 cannot be installed if an adapter is installed in I/O adapter slot 1.

The ServeRAID M5115 supports combinations of 2.5-inch drives and 1.8-inch solid state drives:

  • Up to two 2.5-inch drives only
  • Up to four 1.8-inch drives only
  • Up to two 2.5-inch drives, plus up to four 1.8-inch solid state drives
  • Up to eight 1.8-inch solid state drives

The ServeRAID M5115 SAS/SATA Controller (90Y4390) provides an advanced RAID controller supporting RAID 0, 1, 10, 5, 50, and optional 6 and 60. It includes 1 GB of cache, which can be backed up to Flash when attached to the supercapacitor included with the optional ServeRAID M5100 Series Enablement Kit (90Y4342).

At least one hardware kit is required with the ServeRAID M5115 controller, and there are three hardware kits that are supported that enable specific drive support.

90Y4391 A2XZ ServeRAID M5100 Series SSD Expansion Kit for Flex System x240 1

The hardware kits have the following features:

  • ServeRAID M5100 Series Enablement Kit for Flex System x240 (90Y4342) enables support for up to two 2.5” HDDs or SSDs in the hot-swap bays in the front of the server. It includes a CacheVault unit, which enables MegaRAID CacheVault flash cache protection. This enablement kit replaces the standard two-bay backplane (which is attached via the planar to an onboard controller) with a new backplane that attaches to an included flex cable to the M5115 controller. It also includes an air baffle, which also serves as an attachment for the CacheVault unit.

    MegaRAID CacheVault flash cache protection uses NAND flash memory powered by a supercapacitor to protect data stored in the controller cache. This module eliminates the need for a lithium-ion battery commonly used to protect DRAM cache memory on PCI RAID controllers. To avoid the possibility of data loss or corruption during a power or server failure, CacheVault technology transfers the contents of the DRAM cache to NAND flash using power from the supercapacitor. After the power is restored to the RAID controller, the saved data is transferred from the NAND flash back to the DRAM cache, which can then be flushed to disk.

    Tip: The Enablement Kit is only required if 2.5-inch drives are to be used. If you plan to install four or eight 1.8-inch SSDs only, then this kit is not required.

  • ServeRAID M5100 Series Flex System Flash Kit for x240 (90Y4341) enables support for up to four 1.8-inch SSDs. This kit replaces the standard two-bay backplane with a four-bay SSD backplane that attaches to an included flex cable to the M5115 controller. Because only SSDs are supported, a CacheVault unit is not required, and therefore this kit does not have a supercap. The use of this kit limits which 1.8-inch solid state drives can be used in the x240 as listed in Table 11. Use Flash Kit v2 instead.
  • ServeRAID M5100 Series Flex System Flash Kit v2 for x240 (47C8808) enables support for up to four 1.8-inch SSDs. This kit replaces the standard two-bay backplane with a four-bay SSD backplane that attaches to an included flex cable to the M5115 controller. Because only SSDs are supported, a CacheVault unit is not required, and therefore this kit does not have a supercap. This v2 kit provides support for the latest high-performance SSDs.
  • ServeRAID M5100 Series SSD Expansion Kit for Flex System x240 (90Y4391) enables support for up to four internal 1.8-inch SSDs. This kit includes two air baffles, left and right, which can attach two 1.8-inch SSD attachment locations and Flex cables for attachment to up to four 1.8-inch SSDs.

    Note: The SSD Expansion Kit cannot be installed if the USB Enablement Kit, 49Y8119, is already installed as these kits occupy the same location in the server.

The following table shows the kits required for each combination of drives. For example, if you plan to install eight 1.8-inch SSDs, then you will need the M5115 controller, the Flash kit, and the SSD Expansion kit.

    Adds support for RAID 6 and RAID 60. This is a Feature on Demand license.

  • Performance Upgrade (90Y4412)

    The Performance Upgrade for Flex System (implemented using the LSI MegaRAID FastPath software) provides high-performance I/O acceleration for SSD-based virtual drives by exploiting an extremely low-latency I/O path to increase the maximum I/O per second (IOPS) capability of the controller. This feature boosts the performance of applications with a highly random data storage access pattern, such as transactional databases. Part number 90Y4412 is a Feature on Demand license.

  • SSD Caching Enabler for traditional hard drives (90Y4447)

    The SSD Caching Enabler for Flex System (implemented using the LSI MegaRAID CacheCade Pro 2.0) is designed to accelerate the performance of hard disk drive (HDD) arrays with only an incremental investment in solid-state drive (SSD) technology. The feature enables the SSDs to be configured as a dedicated cache to help maximize the I/O performance for transaction-intensive applications, such as databases and web serving. The feature tracks data storage access patterns and identifies the most frequently accessed data. The hot data is then automatically stored on the SSDs that are assigned as a dedicated cache pool on the ServeRAID controller. Part number 90Y4447 is a Feature on Demand license. This feature requires at least one SSD drive be installed.

Internal tape drives

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

Optical drives

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.

Note: The USB port on the compute nodes supply up to 0.5 A at 5 V. For devices that require more power, an additional power source will be required.

Embedded 10Gb Virtual Fabric Adapter

Some models of the x240 include an Embedded 10Gb Virtual Fabric Adapter (VFA, also known as LAN on Motherboard or LOM) built into the system board. Table 2 lists what models of the x240 include the Embedded 10Gb Virtual Fabric Adapter. Each x240 model that includes the embedded 10Gb VFA also has the Compute Node Fabric Connector installed in I/O connector 1 (and physically screwed onto the system board) to provide connectivity to the Enterprise Chassis midplane. Figure 3 shows the location of the Fabric Connector.

The Fabric Connector enables port 1 on the embedded 10Gb VFA to be routed to I/O module bay 1 and port 2 to be routed to I/O module bay 2. The Fabric Connector can be unscrewed and removed, if required, to allow the installation of an I/O adapter on I/O connector 1.

The Embedded 10Gb VFA is based on the Emulex BladeEngine 3 (BE3), which is a single-chip, dual-port 10 Gigabit Ethernet (10GbE) Ethernet Controller. These are some of the features of the Embedded 10Gb VFA:

  • PCI-Express Gen2 x8 host bus interface
  • Supports connection to 10 Gb and 1 Gb Flex System Ethernet switches
  • Supports multiple virtual NIC (vNIC) functions
  • TCP/IP Offload Engine (TOE enabled)
  • SRIOV capable
  • RDMA over TCP/IP capable
  • iSCSI and FCoE upgrade offering via FoD

I/O expansion options

The x240 has two I/O expansion connectors for attaching I/O adapter cards. There is a third expansion connector designed to connect an expansion node such as the PCIe Expansion Node. The I/O expansion connectors are a very high-density 216-pin PCIe connector. Installing I/O adapter cards allows the server to connect with switch modules in the Flex System Enterprise Chassis. Each slot has a PCI Express 3.0 x16 host interface and both slots support the same form-factor adapters.

The following figure shows the location of the I/O expansion connectors.

Location of the I/O adapter slots in the NGP x240 Compute Node
Figure 7. Location of the I/O adapter slots in the Flex System x240 Compute Node

All I/O adapters are the same shape and can be used in any available slot.. 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 ports of the adapter are enabled, which improves performance and network availability.

* The feature is not available to be configured using model 7863-10X in e-config. Use model 8737-15X instead.

The PCIe Expansion Node has the following features:

  • Support for up to four standard PCIe 2.0 adapters:
    • Two PCIe 2.0 x16 slots that support full-length, full-height adapters
    • Two PCIe 2.0 x8 slots that support half-length, low-profile adapters
  • Support for PCIe 3.0 adapters by operating them in PCIe 2.0 mode
  • Support for one full-length, full-height double-wide adapter (consuming the space of the two full-length, full-height adapter slots)
  • Support for PCIe cards with higher power requirements -- a single adapter card (up to 225W), or to two adapters (up to 150W each)
  • Two Flex System I/O expansion connectors for to further expand the I/O capability of the attached compute node.

Note: The use of the PCIe Expansion Node requires that the x240 Compute Node have both processors installed.

Network adapters

As described in "Embedded 10Gb Virtual Fabric Adapter," certain models (those with a model number of the form x2x) have a 10Gb Ethernet controller on the system board, and its ports are routed to the midplane and switches installed in the chassis via a Compute Note Fabric Connector that takes the place of an adapter in I/O slot 1.

Models without the Embedded 10Gb Virtual Fabric Adapter (those with a model number of the form x1x) do not include any other Ethernet connections to the Enterprise Chassis midplane as standard. Therefore, for those models, an I/O adapter must be installed in either I/O connector 1 or I/O connector 2 to provide network connectivity between the server and the chassis midplane and ultimately to the network switches.

The following table lists the supported network adapters and upgrades. Adapters can be installed in either slot. However, compatible switches must be installed in the corresponding bays of the chassis. All adapters can also be installed in the PCIe Expansion Node. The "Maximum supported" column indicates the number of adapter than can be installed in the server and in the PCIe Expansion Node (PEN).

Power supplies

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

Integrated virtualization

The x240 supports the ESXi hypervisor on a USB memory key via the x240 USB Enablement Kit. This kit offers two internal USB ports. The x240 USB Enablement Kit and the supported USB memory keys are listed in the following table.

There are two types of USB keys, preloaded keys or blank keys. Blank keys allow you to download a Lenovo customized version of ESXi and load it onto the key. Preload keys are shipped with a specific version of ESXi already loaded. The x240 supports one or two keys installed, but only certain combinations:

Supported combinations:

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

Unsupported combinations:

  • Two preload keys

Installing two preloaded keys will prevent ESXi from booting as described in http://kb.vmware.com/kb/1035107. Having two keys 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 gets corrupted.

Note: The x240 USB Enablement Kit and USB memory keys are not supported if the SSD Expansion Kit (90Y4391) is already installed, because these kits occupy the same location in the server.

Light path diagnostics

For quick problem determination when located physically at the server, the x240 offers a three-step guided path:

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

The x240 light path diagnostics panel is visible when you remove the server from the chassis. The panel is located on the top right-hand side of the compute node, as shown in the following figure.

Location of x240 light path diagnostics panel
Figure 11. Location of x240 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 in the light path diagnostics panel are listed in the following table.

Table 21. Light path diagnostic panel LEDs

LED Meaning
LP The light path diagnostics panel is operational.
S BRD A system board error is detected.
MIS A mismatch has occurred between the processors, DIMMs, or HDDs within the configuration as reported by POST.
NMI A non maskable interrupt (NMI) has occurred.
TEMP An over-temperature condition occurs that was critical enough to shut down the server.
MEM A memory fault has occurred. The corresponding DIMM error LEDs on the system board are also lit.
ADJ A fault is detected in the adjacent expansion unit (if installed).

Remote management

The server contains a Lenovo Integrated Management Module II (IMM2), which interfaces with the advanced management module in the chassis. The combination of these 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
