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” on page 44.
• Lenovo X-Architecture
Lenovo X-Architecture systems combine proven, innovative designs to make your
x86-processor-based compute node powerful, scalable, and reliable. For more information, see
http://shop.lenovo.com/us/en/systems/ servers/mission-critical/.
• Integrated management module II
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 Chapter 4 “Accessing the IMM2” on page 47.
• Large system-memory capacity
The compute node supports up to 192 GB of system memory. The memory controller provides support
for up to 12 industry-standard registered ECC DDR3 on low-profile (LP) DIMMs on the system board. For
the most current list of supported DIMMs, see http://www.lenovo.com/ serverproven/.
• Light path diagnostics
Light path diagnostics provides light-emitting diodes (LEDs) to help you diagnose problems. For more
information, see “Light path diagnostics” on page 61.
• Microprocessor technology
The compute node supports up to two multi-core IntelXeon microprocessors. For more information about
supported microprocessors and their part numbers, see http://www.lenovo.com/ serverproven/.
Note: The optional microprocessors 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.
Optional expansion nodes are available to provide a cost-effective way for you to increase and customize
the capabilities of the compute node. Expansion nodes support a wide variety of industry-standard PCI
Express, network, storage, and graphics adapters. For additional information, see "PCIe Expansion
Node" at http://pic.dhe.ibm.com/infocenter/ flexsys/information/topic/ com.lenovo.acc.pme.doc/

• 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 supplies 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:
