Figure 1. The Flex System x440 Compute Node

Flex System is a new category of computing that integrates multiple server architectures, networking, storage, and system management capability into a single system that is easy to deploy and manage. Flex System has full, built-in virtualization support of servers, storage, and networking to speed provisioning and increased resiliency. In addition, it supports open industry standards, such as operating systems, networking and storage fabrics, virtualization, and system management protocols, to easily fit within existing and future data center environments. Flex System is scalable and extendable with multi-generation upgrades to protect and maximize IT investments.

This section describes the key features of the compute node.

Scalability and performance

The x440 offers numerous features to boost performance, improve scalability, and reduce costs:

• The Intel Xeon processor E5-4600 product family improves productivity by offering superior system performance with 8-core processors and up to 2.9 GHz core speeds, up to 20 MB of L3 cache, and up to two 8 GTps QPI interconnect links.
• Up to four processors, 32 cores, and 64 threads maximize the concurrent execution of multithreaded applications.
• 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 multithreaded applications by enabling simultaneous multithreading 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 compared to Intel Xeon 5600 series processors.
• Up to 48 DDR3 ECC memory RDIMMs provide speeds up to 1600 MHz and a memory capacity of up to 768 GB. Load-reduced DIMMs (LRDIMMs) are supported with a maximum capacity of 1.5 TB of memory.
• The use of solid-state drives (SSDs) instead of or along with traditional hard disk 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 32 virtual I/O ports per compute node with integrated 10 Gb Ethernet ports, offering the choice of Ethernet, Fibre Channel, iSCSI, or FCoE connectivity. With models without integrated 10 Gb ports, you can have up to 64 virtual I/O ports by installing four CN4054 10Gb Virtual Fabric Adapters.
• The x440 offers PCI Express 3.0 I/O expansion capabilities that improve the theoretical maximum bandwidth by 60% (8 GTps 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 configuration reduces I/O latency and increases overall system performance.
• Support for high-bandwidth I/O adapters, up to four in each x440 Compute Node. Support for 10 Gb Ethernet, 16 Gb Fibre Channel, and FDR InfiniBand.

Availability and serviceability

The x440 provides many features to simplify serviceability and increase system uptime:

• Chipkill, memory mirroring, and memory rank sparing for redundancy in the event of a non-correctable memory failure.
• Tool-less cover removal provides easy access to upgrades and serviceable parts, such as processor, memory, and adapter cards.
• Hot-swap drives supporting integrated RAID 1 redundancy for data protection and greater system uptime.
• A light path diagnostics panel and individual light path LEDs to 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), which detects when system components (such as processors, memory, and hard disk drives) operate outside of standard thresholds and generates proactive alerts in advance of possible failure, therefore increasing uptime.
• Solid-state drives (SSDs), which offer better reliability than traditional mechanical HDDs for greater uptime.
• Built-in Integrated Management Module II (IMM2) continuously monitors system parameters, triggers alerts, and performs recovering actions in case of failures to minimize downtime.
• Built-in diagnostics using Dynamic Systems Analysis (DSA) Preboot speeds up troubleshooting tasks to reduce service time.
• Three-year customer replaceable unit and on-site limited warranty, next business day 9x5. Optional service upgrades are available.

Manageability and security

Powerful systems management features simplify local and remote management of the x440:

• The x440 includes an Integrated Management Module II (IMM2) to monitor server availability and perform remote management.
• An integrated industry-standard Unified Extensible Firmware Interface (UEFI) enables improved setup, configuration, and updates, and simplifies error handling.
• Integrated Trusted Platform Module (TPM) V1.2 support enables advanced cryptographic functionality, such as digital signatures and remote attestation.
• Industry-standard AES NI support for faster and stronger encryption.
• Integrates with the Flex System Manager for proactive systems management. It offers comprehensive systems management for the entire Flex System platform, which increases uptime, reduces costs, and improves productivity through advanced server management capabilities.

• Intel Execute Disable Bit functionality can prevent certain classes of malicious buffer overflow attacks when combined with a supporting 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 protected from all other software running on a system.

Energy efficiency

The x440 offers the following energy-efficiency features to save energy, reduce operational costs, increase energy availability, and contribute to a green environment:

• Component-sharing design of the Flex System chassis provides ultimate power and cooling savings.
• The Intel Xeon processor E5-4600 product family offers better performance over the previous generation while fitting into the same TDP limits.
• Intel Intelligent Power Capability powers individual processor elements on and off as needed, to reduce power draw.
• Low-voltage Intel Xeon processors draw less energy to satisfy demands of power and thermally constrained data centers and telecommunication environments.
• Low-voltage 1.35 V DDR3 memory RDIMMs consume 15% less energy than 1.5 V DDR3 RDIMMs.
• SSDs consume as much as 80% less power than traditional spinning 2.5-inch HDDs.
• The x440 uses hexagonal ventilation holes, a part of IBM Calibrated Vectored Cooling™ technology. Hexagonal holes can be grouped more densely than round holes, providing more efficient airflow through the system.

The following table lists the standard specifications.

The x440 servers 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.

** Processor detail: Processor quantity and model, cores, core speed, L3 cache, memory speed, and power consumption.
* For models Axx and Bxx, the standard DIMM is rated at 1333 MHz, but operates at up to 1066 MHz to match the processor memory speed.
† The 2.5-inch drive bays can be replaced and expanded with additional internal bays to support up to eight 1.8-inch solid-state drives (SSDs). See the "Internal disk storage options" section.
‡ The x4x models include two Embedded 10Gb Virtual Fabric Ethernet controllers. Connections are routed using a Fabric Connector. The Fabric Connectors preclude the use of an I/O adapter in I/O connectors 1 and 3, except the ServeRAID M5115 controller, which can be installed in slot 1.

The x440 is supported in the Flex System Enterprise Chassis. Up to seven x440 compute nodes can be installed in the chassis in 10U of rack space. The actual number of x440 Compute Nodes that can be installed in a chassis depends on these factors:

• The TDP power rating for the processors that are installed in the x440
• The number of power supplies installed
• The capacity of the power supplies installed (2100 W or 2500 W)
• The power redundancy policy used (N+1 or N+N)

The following table provides guidelines about what number of x440 Compute Nodes can be installed. For more guidance, 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 x440 Compute Nodes that are installable
• Yellow = Some bays must be left empty in the chassis

Table 3. Maximum number of x440 Compute Nodes installable based on power supplies installed and power redundancy policy used

The x440 supports the processor options listed in the following table. The server supports one or two or four processors (three processors is not supported). For a given processor model (for example, the Xeon E5-4603), there are two part numbers: the first one is for the rear two processors (CPUs 1 and 2) and include taller heat sinks; the second part number is for the front two processors (CPUs 3 and 4) and include shorter heat sinks.

The table also shows which server models have each processor standard. If no corresponding where used model for a particular processor is listed, then this processor is available only through Configure to Order (CTO).

Table 4. Processor options

* When two feature codes are specified, the first feature code is for CPU 1 and the second feature code is for CPU 2

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 Lenovo system warranty, and Lenovo provides service and support worldwide.

The x440 supports DDR3 memory. The compute node supports up to 48 DIMMs when four processors are installed, with 12 DIMMs for each processor. Each processor has four memory channels, and there are three DIMMs per channel.

The following rules apply when selecting the memory configuration:

• The server supports UDIMMs, RDIMMs and LRDIMMs.
• Mixing different types of memory (eg RDIMMs and LRDIMMs) is not supported.
• 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 maximum number of ranks per one channel is eight (with the exception of Load Reduced DIMMs, where more than eight ranks are supported, because one quad-rank LRDIMM provides the same electrical load on a memory bus as a single-rank RDIMM).
• The maximum quantity of DIMMs that can be installed in the server depends on the number of processors installed. The following table shows the maximum when all four processors are installed. When two processors are installed, the maximum quantity supported is a half of the quantity that is shown.
• All DIMMs in the server operate at the same speed, which is determined as the lowest value of:
  • The memory speed that is supported by the specific processor.
  • The lowest of maximum operating speeds for the selected memory configuration that depends on rated speed, operating voltage, and quantity of DIMMs per channel, as shown under "Max. operating speed" section in the table.

The following table shows the maximum memory speeds that are achievable based on the installed DIMMs and the number of DIMMs per channel. The table also shows the maximum memory capacity at any speed supported by the DIMM and the maximum memory capacity at the rated DIMM speed.

In the table:

• The entries highlighted in red text indicate that the x440 supports higher memory frequencies than the Intel processor specification. In some instances, this configuration also results larger memory capacity that the specification recommends.
• 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 the rated speed.

* The maximum quantity supported is shown for four processors installed. When two processors are installed, the maximum quantity supported is a half of the quantity that is shown. When one processor is installed, the quantity is one quarter of that shown.

The following memory protection technologies are supported:

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

If memory mirroring is used, then DIMMs must be installed in pairs (minimum of one pair per processor), 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 following table lists the memory options that are available for the x440 Compute Node.

The x440 server has two 2.5-inch hot-swap drive bays accessible from the front of the blade server (Figure 2). These bays are connected to the integrated 4-port LSI SAS2004 6 Gbps SAS/SATA RAID-on-Chip (ROC) controller.

The integrated LSI SAS2004 ROC has the following features:

• Four-port 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 levels 0 (Integrated Striping), 1 (Integrated Mirroring), 10 (Integrated Mirroring and Striping), and 1E (Integrated Mirroring Enhanced)

The x440 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.

In addition, the x440 supports up to eight 1.8-inch SSDs 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 described 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 SSDs:

• 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 SSDs
• Up to eight 1.8-inch SSDs

The ServeRAID M5115 SAS/SATA Controller (90Y4390) provides an advanced RAID controller supporting RAID 0, 1, 10, 5, 50, and, optionally, 6 and 60. It includes 1 GB of cache, which can be backed up to flash memory when attached to the supercapacitor included with the optional ServeRAID M5100 Series Enablement Kit (46C9030).

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, as listed in the following table.

* Ensure the IMM2 firmware of the x440 is at least level 40A for full compatibility

The ServeRAID M5115 hardware kits are as follows:

• ServeRAID M5100 Series Enablement Kit for Flex System x440 (46C9030) enables support for up to two 2.5-inch 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 two standard 1-bay backplanes (which are attached through the planar to an onboard controller) with new 1-bay backplanes that attach 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 memory using power from the supercapacitor. After the power is restored to the RAID controller, the saved data is transferred from the NAND flash memory 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 x440 (47C8809) 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 x440 (46C9032) enables support for up to four internal 1.8-inch SSDs. This kit includes two air baffles 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 above kits are specific for the x440 and cannot be used with the x240 or x220.

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 need the M5115 controller, the Flash Kit, and the SSD Expansion kit.

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 previous 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 previous 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
• Four on trays above the memory banks

The ServeRAID M5115 controller has the following specifications:

• Eight internal 6 Gbps SAS/SATA ports
• PCI Express 3.0 x8 host interface
• 6 Gbps throughput per port
• 800 MHz dual-core IBM PowerPC® processor with LSI SAS2208 6 Gbps RAID on Chip (ROC) controller
• Support for RAID levels 0, 1, 10, 5, 50 standard; support for RAID 6 and 60 with optional upgrade using 90Y4411
• Onboard 1 GB data cache (DDR3 running at 1333 MHz) with optional flash backup (MegaRAID CacheVault technology) as part of the Enablement Kit 46C9030.
• 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) is 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 upgrade, and SSD caching enabler. The feature upgrades are as listed in the following table. These are all Feature on Demand (FoD) license upgrades.

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 using a 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 HDD arrays with only an incremental investment in 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 https://support.lenovo.com/us/en/documents/MIGR-5094754 for details.

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.

* Supports self-encrypting drive (SED) technology. For more information, see Self-Encrypting Drives for System x at http://lenovopress.com/tips0761.

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.

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 x440 include two Embedded 10Gb Virtual Fabric controllers (VFA, also known as LAN on Motherboard (LOM)) built into the system board. Table 2 lists what models of the x440 include the Embedded 10Gb Virtual Fabric controllers. Each x440 model that includes the embedded 10 Gb also has the Compute Node Fabric Connector installed in each of I/O connectors 1 and 3 (and physically screwed onto the system board) to provide connectivity to the Enterprise Chassis midplane.

The Fabric Connector enables port 1 of each embedded 10 Gb controller to be routed to I/O module bay 1 and port 2 of each controller to be routed to I/O module bay 2. The Fabric Connectors can be unscrewed and removed, if required, to allow the installation of an I/O adapter on I/O connector 1 and 3.

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

• 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

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 controller. To upgrade both controllers, you need two FoD licenses.

The x440 has four I/O expansion connectors for attaching I/O adapter cards, as shown in Figure 6. There is a fifth expansion connector (under I/O adapter 4) designed for future expansion options. The I/O expansion connector is 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 all slots support the same form-factor adapters.

Note: A second processor must be installed in order to use I/O adapter slots 3 and 4 in the x440 compute node. This is because the PCIe lanes used to drive I/O slots 3 and 4 are routed to processors 2 and 4.

Figure 6 shows the location of the I/O expansion connectors.

Figure 6. Location of the I/O adapter slots in the Flex System x440 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.

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

Figure 7 shows the location of the switch bays in the Flex System Enterprise Chassis.

Figure 7. Location of the switch bays in the Flex System Enterprise Chassis

Figure 8 shows how 2-port adapters are connected to switches installed in the chassis.

Figure 8. Logical layout of the interconnects between I/O adapters and I/O modules

As described in the Embedded 10Gb Virtual Fabric section, certain models (those with a model number of the form x4x) have two 10 Gb Ethernet controllers on the system board, and its ports are routed to the midplane and switches installed in the chassis through two Compute Note Fabric Connectors that takes the place of adapters in I/O slots 1 and 3.

Models without the Embedded 10Gb Virtual Fabric controller (those with a model number of the form 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 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 any slot. However, compatible switches must be installed in the corresponding bays of the chassis.

* For x4x models with two Embedded 10Gb Virtual Fabric controllers standard, the Compute Node Fabric Connectors occupy the same space as the I/O adapters in I/O slots 1 and 3, so you have to remove the Fabric Connectors if you plan to install adapters in those I/O slots. To use slots 3 and 4 requires the second processor.

For adapter-to-switch compatibility, see the Flex System Interoperability Guide: http://lenovopress.com/fsig

The following table lists storage HBAs supported by the x440 server.

For x4x models with two Embedded 10Gb Virtual Fabric controllers standard, the Compute Node Fabric Connectors occupy the same space as the I/O adapters in I/O slots 1 and 3, so you have to remove the Fabric Connectors if you plan to install adapters in those I/O slots. To use slots 3 and 4 requires the second processor.

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

The x440 supports the ESXi hypervisor on a USB memory key via 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, preloaded keys or blank keys. Blank keys allow you to download a customized version of ESXi and load it onto the key. The x440 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.

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

For quick problem determination when located physically at the server, the x440 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 x440 light path diagnostics panel is visible when you remove the server from the chassis. The panel is located at the upper right side of the compute node, as shown in Figure 9.

Figure 9. Location of x440 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.

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
