The x240 is supported in the Flex System chassis in the following table.

Up to 14 x240 Compute Nodes can be installed in the chassis, however, the actual number that can be installed in a chassis depends on these factors:

• The TDP power rating for the processors that are installed in the x240
• The number of power supplies installed in the chassis
• The capacity of the power supplies installed (2100 W or 2500 W)
• The chassis power redundancy policy used (N+1 or N+N)

The following table provides guidelines about what number of x240 Compute Nodes can be installed. For more guidance, use the Power Configurator, found at the following website:
https://support.lenovo.com/us/en/documents/LNVO-PWRCONF

In the table:

• Green = No restriction to the number of x240 Compute Nodes that are installable
• Yellow = Some bays must be left empty in the chassis

Table 4. Maximum number of x240 Compute Nodes installable based on power supplies installed and power redundancy policy used

The x240 supports the processor options listed in the following table. The server supports one or two processors. The table also shows which server models have each processor standard, if any.

Table 5. Processor options

* The first feature code is for processor 1 and second feature code is for processor 2.
** Use of the Intel Xeon E5-2667 v2 processor in the Flex System x240 Compute Node is limited to 30 °C up to 3000 feet (914 m). Above 3000 feet, a de-rating of 1 °C for every 600 feet (182 m) should be applied. Use of the ServeRAID M5115 SAS/SATA RAID Controller with the E5-2667 v2 processor is not supported. Flex System configurations using the E5-2667 v2 processor will operate at acoustic levels significantly greater than typical Flex System levels, and the following noise hazard warning may apply: "Notice: Government regulations (such as those prescribed by OSHA or European Community Directives) may govern noise level exposure in the workplace and may apply to you and your server installation. The actual sound pressure levels in your installation depend upon a variety of factors, including the number of racks in the installation; the size, materials, and configuration of the room; the noise levels from other equipment; the room ambient temperature, and employees’ location in relation to the equipment. Further, compliance with such government regulations also depends upon a variety of additional factors, including the duration of employees’ exposure and whether employees wear hearing protection. Lenovo recommends that you consult with qualified experts in this field to determine whether you are in compliance with the applicable regulations."

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

The following table lists memory options available for the x240 compute node with E5-2600 v2 processors. DIMMs can be installed one at a time, but for performance reasons, install them in sets of four (one for each of the four memory channels).

Table 6. Memory options for the x240 with E5-2600 v2 processors

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 two tables (Part 1 and Part 2) show 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 gray background indicate when the specific combination of DIMM voltage and number of DIMMs per channel still allows the DIMMs to operate at rated speed.

Table 7. Maximum memory speeds (Part 1 - UDIMMs and LRDIMMs)

* The maximum quantity supported is shown for two processors installed. When one processor is installed, the maximum quantity supported is half of that shown.
† NS = Not supported. UDIMMs only support up to 2 DIMMs per channel.

Table 8. Maximum memory speeds (Part 2 - Single-rank and dual-rank RDIMMs)

† The maximum quantity that is supported is shown for two processors installed. When one processor is installed, the maximum quantity that is supported is half of that shown.
* 00D5044 (8 GB) operates at 1066 MHz at three DIMMs per channel; 46W0672 (16 GB) operates at 1333 MHz at three DIMMs per channel
** 00D5028 (4 GB) and 00D5040 (8 GB) operate at 1066 MHz at three DIMMs per channel; 00D5048 (16 GB) operates at 1333 MHz at three DIMMs per channel

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.

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.

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.

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 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.

  Note: The original ServeRAID M5100 Series Flex System Flash Kit for x240, 90Y4341 is not supported.

• 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.

Table 10. ServeRAID M5115 hardware kit usage matrix

The following figure shows how the ServeRAID M5115 and the Enablement Kit are installed in the server to support two 2.5-inch drives with MegaRAID CacheVault flash cache protection (row 1 of the preceding table).

Figure 4. The ServeRAID M5115 and the Enablement Kit installed

The following figure shows how the ServeRAID M5115 and Flash and SSD Expansion Kits are installed in the server to support eight 1.8-inch solid-state drives (row 4 of the preceding table).

Figure 5. ServeRAID M5115 with Flash and SSD Expansion Kits installed

The eight SSDs are installed in the following locations:

• Four in the front of the system in place of the two 2.5-inch drive bays

• Onboard 1 GB data cache (DDR3 running at 1333 MHz) with optional flash backup (MegaRAID CacheVault technology) as part of the Enablement Kit 90Y4342.
• Support for SAS and SATA HDDs and SSDs
• Support for intermixing SAS and SATA HDDs and SSDs; mixing different types of drives in the same array (drive group) not recommended
• Support for self-encrypting drives (SEDs) with MegaRAID SafeStore
• Optional support for SSD performance acceleration with MegaRAID FastPath and SSD caching with MegaRAID CacheCade Pro 2.0 (90Y4447)
• Support for up to 64 virtual drives, up to 128 drive groups, up to 16 virtual drives per one drive group, and up to 32 physical drives per one drive group
• Support for logical unit number (LUN) sizes up to 64 TB
• Configurable stripe size up to 1 MB
• Compliant with Disk Data Format (DDF) configuration on disk (COD)
• S.M.A.R.T. support
• MegaRAID Storage Manager management software

Optional add-ons to the ServeRAID M5115 controller are RAID 6 support, SSD performance accelerator, and SSD caching enabler. The feature upgrades are as listed in the following table. These are all FoD license upgrades.

Table 11. Supported upgrade features

These features are described as follows:

• RAID 6 Upgrade (90Y4410)

  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.

  Note: Not all SSDs support SSD Caching Enabler (CacheCade) feature. See http://ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5094754 for details.

The 2.5" drive bays support SAS or SATA hard disk drives (HDDs) or SATA solid state drives (SSDs). The following table lists the supported 2.5" drive options.

The 1.8-inch solid state drives supported are listed in the following table. The use of 1.8-inch drives requires the ServeRAID M5115 SAS/SATA controller as described in the next section.

The x240 supports the attachment of the Flex System Storage Expansion Node. The Flex System Storage Expansion Node provides the ability to attach additional 12 hot-swap 2.5-inch HDDs or SSDs locally to the attached compute node. The Storage Expansion Node provides storage capacity for Network Attach Storage (NAS) workloads, providing flexible storage to match capacity, performance and reliability needs.

Model 8737-HBx includes the Storage Expansion Node as standard as listed in Table 2. All other models support the SEN as an option.

The following figure shows the Flex System Storage Expansion Node attached to a compute node.

Figure 6. Flex System Storage Expansion Node (right) attached to a compute node (left)

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

For more information, see the Product Guide on the Flex System Storage Expansion Node:
http://lenovopress.com/tips0914

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

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.

Some models of the x240 -- those with a model of the form 8737-x4x -- include an Embedded 10Gb Virtual Fabric Adapter (VFA, also known as LAN on Motherboard or LOM) built into the system board. Table 2 lists the 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 3R (BE3R), 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)
• SR-IOV capable
• RDMA over TCP/IP capable
• iSCSI and FCoE upgrade offering via FoD

The following table lists the ordering information for the Virtual Fabric Advanced Software Upgrade (LOM), which enables the iSCSI and FCoE support on the Embedded 10Gb Virtual Fabric Adapter.

Table 16. Feature on Demand upgrade for FCoE and iSCSI support

Some models of the x240 -- those with a model of the form 8737-xMx -- include the Flex System CN4022 2-port 10Gb Converged Adapter installed in slot 1. Table 2 lists the models with this adapter standard. These models require that a compatible Ethernet switch be installed in I/O module bays 1 and 2 of the chassis.

The features of the CN4022 2-port 10Gb Converged Adapter include the following features:

• One Broadcom BCM57840 ASIC
• Connection to either 1 Gb or 10 Gb data center infrastructure (1 Gb and 10 Gb auto-negotiation)
• PCI Express 3.0 x8 host interface
• Full line-rate performance
• Supports 10 Gb Ethernet, FCoE, and iSCSI out of the box (no Features on Demand upgrade required)
• Supports vNIC - Switch Independent Mode

For details about this adapter, see the Product Guide:
http://lenovopress.com/tips1087

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.

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 following figure shows the location of the switch bays in the Flex System Enterprise Chassis.

Figure 8. Location of the switch bays in the Flex System Enterprise Chassis

The following figure shows how two-port adapters are connected to switches installed in the chassis.

Figure 9. Logical layout of the interconnects between I/O adapters and I/O modules

As described in "Embedded 10Gb Virtual Fabric Adapter," certain models (those with a model number of the form 8737-x4x or 8737-xDx) 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 8737-x2x) 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).

Table 18. Network adapters

* For x4x models (where the Embedded 10Gb Virtual Fabric Adapter standard), and for xMx models (where a CN4022 2-port 10Gb Converged Adapter is standard), only one extra adapter can be installed in the compute node.

For adapter-to-switch compatibility, see the Flex System Interoperability Guide:

The following table lists storage HBAs supported by the x240 server, both internally in the compute node and in the PCIe Expansion Node.

Table 19. Storage adapters

* For x4x models (where the Embedded 10Gb Virtual Fabric Adapter standard), and for xMx models (where a CN4022 2-port 10Gb Converged Adapter is standard), only one extra adapter can be installed in the compute node.

The compute node supports the PCIe Flash Storage Adapters when installed in an attached PCIe Expansion Node (PEN), however the PEN is now withdrawn from marketing.

For customers who already have x240 compute nodes with attached PCIe Expansion Nodes, see the PCIe Expansion Node Product Guide for details about supported adapters: https://lenovopress.com/tips0906-flex-system-pcie-expansion-node

The compute node supports GPUs when installed in an attached PCIe Expansion Node (PEN), however the PEN is now withdrawn from marketing.

For customers who already have x240 compute nodes with attached PCIe Expansion Nodes, see the PCIe Expansion Node Product Guide for details about supported adapters: https://lenovopress.com/tips0906-flex-system-pcie-expansion-node

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

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.

Table 20. Virtualization options

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.

Figure 10. 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

The server contains an 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
