What your compute node offers

Your compute node offers features such as the integrated management module 2, hard disk drive support, systems-management support, microprocessor technology, integrated network support, I/O expansion, large system-memory capacity, light path diagnostics LEDs, PCI Express, and power throttling.

• Features on Demand

  If a Features on Demand feature is integrated in the compute node or in an optional device that is installed in the compute node, you can purchase an activation key to activate the feature. For information about Features on Demand, see the IBM Features on Demand website.

• Dynamic System Analysis (DSA)
  IBM Dynamic System Analysis (DSA) collects and analyzes system information to aid in diagnosing compute node problems. DSA collects the following information about the compute node:

  • Drive health information
  • Event logs for ServeRAID controllers and service processors
  • Hardware inventory, including PCI and USB information
  • Installed applications and hot fixes
  • Kernel modules
  • Light path diagnostics status
  • Network interfaces and settings
  • Performance data and details about processes that are running
  • RAID and controller configuration
  • Integrated management module 2 status and configuration
  • System configuration
  • Vital product data and firmware information

  DSA creates a DSA log, which is a chronologically ordered merge of the system-event log (as the IPMI event log), the IMM event log (as the ASM event log), and the operating-system event logs. You can send the DSA log as a file to a support representative or view the information as a text file or HTML file.

  For more information, see IBM Dynamic System Analysis Preboot diagnostic program.

• Flexible network support
  The compute node provides flexible network capabilities:

  • Models with embedded virtual fabric: The integrated Emulex BE3 dual-port 10 Gigabit Ethernet controller supports connections to a 10 Mbps, 100 Mbps, or 1000 Mbps network through an Ethernet-compatible switch module in the chassis. The controller supports connections at 10 Gb. The controller also supports Wake on LAN® technology. You can install an additional I/O expansion adapter for network support.
  • Models without embedded virtual fabric: The compute node has connectors on the system board for optional expansion adapters for adding network communication capabilities to the compute node. You can install up to two I/O expansion adapters for network support. This provides the flexibility to install expansion adapters that support a variety of network communication technologies.
• Hard disk drive support

  The compute node supports up to two hot-swap hard disk drives. You can implement RAID 0 or RAID 1 for the drives.

• IBM ServerGuide Setup and Installation CD

  The ServerGuide Setup and Installation CD, which you can download from the web, provides programs to help you set up the compute node and install a Windows operating system. The ServerGuide program detects installed optional hardware devices and provides the correct configuration programs and device drivers. For more information, see Using the ServerGuide Setup and Installation CD.

• Integrated management module II (IMM2)

  The integrated management module II (IMM2) combines systems-management functions, video controller, the remote presence, and blue-screen capture features in a single chip. The IMM2 provides advanced systems-management control, monitoring, and alerting function. If an environmental condition exceeds a threshold or if a system component fails, the IMM2 lights LEDs to help you diagnose the problem, records the error in the IMM event log, and alerts you to the problem.

  Optionally, the IMM2 also provides a virtual presence capability for remote systems management capabilities. The IMM2 provides remote systems management through industry-standard interfaces:

  • Common Information Model (CIM)
  • Intelligent Platform Management Interface (IPMI) version 2.0
  • Simple Network Management Protocol (SNMP) version 3.0
  • Web browser

  For more information, see Accessing the IMM2.

• Large system-memory capacity

  The compute node supports up to 1536 GB of system memory. The memory controller provides support for up to 48 industry-standard registered ECC DDR3 on low-profile (LP) DIMMs on the system board. For the most current list of supported DIMMs, see the IBM ServerProven website.

• Light path diagnostics

  Light path diagnostics provides light-emitting diodes (LEDs) to help you diagnose problems. For more information, see Light path diagnostics.

• Microprocessor technology

  The compute node supports up to four multi-core Intel Xeon microprocessors. For more information about supported microprocessors and their part numbers, see Parts listing, Types 7917, 7167, 2590 and 2584.

  Note: The optional microprocessors that IBM supports are limited by the capacity and capability of the compute node. Any microprocessor that you install must have the same specifications as the microprocessor that came with the compute node.
• PCI Express

  PCI Express is a serial interface that is used for chip-to-chip interconnect and expansion adapter interconnect. You can add optional I/O and storage devices.

• Power throttling

  By enforcing a power policy known as power-domain oversubscription, the Flex System chassis can share the power load between two or more power supply modules to ensure sufficient power for each device in the Flex System chassis. This policy is enforced when the initial power is applied to the Flex System chassis or when a compute node is inserted into the Flex System chassis.

  The following settings for this policy are available:

  • Basic power management
  • Power module redundancy
  • Power module redundancy with compute node throttling allowed

  You can configure and monitor the power environment by using the Chassis Management Module. For more information, see the the IBM Flex System Chassis Management Module: Command-Line Interface Reference Guide.

• Systems-management support

  The compute node IMM2 provides a Web interface for remote systems-management support. You can use the interface to view system status, and control server management functions and IMM management settings.

  The IMM2 communicates with the IBM Flex System Chassis Management Module (CMM) and IBM® Flex System Manager management software (if installed).

  • CMM is a hot-swap module that provides system-management functions for all components in an Flex System chassis. It controls a serial port for remote connection and a 1 Gbps Ethernet remote-management connection. For more information, see the the IBM Flex System Chassis Management Module: Command-Line Interface Reference Guide.
  • IBM Flex System Manager management software is a platform-management foundation that streamlines the way you manage physical and virtual systems in a heterogeneous environment. By using industry standards, IBM Flex System Manager management software supports multiple operating systems and virtualization technologies. For more information, see the the IBM Flex System Manager Software Installation and Service Guide.
