on low-profile (LP) DIMMs on the system board. For the most current list of
supported DIMMs, see http://www.ibm.com/systems/info/x86servers/
serverproven/compat/us/.
v 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
57.
v 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 Chapter 5, “Parts listing, Types 7917 and 2584,” on page 51.
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.
v 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.
v Power throttling
By enforcing a power policy known as power-domain oversubscription, the IBM
Flex System chassis can share the power load between two or more power
supply modules to ensure sufficient power for each device in the IBM Flex
System chassis. This policy is enforced when the initial power is applied to the
IBM Flex System chassis or when a compute node is inserted into the IBM 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 "IBM Flex System Chassis
Management Module: Command-Line Interface Reference Guide" at
http://ralfss21.raleigh.ibm.com:8099/help/topic/com.ibm.acc.cmm.doc/
cmm_cli_guide.html.
v 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 IBM Flex System chassis. It controls a serial port for
remote connection and a 1 Gbps Ethernet remote-management connection.
For more information, see the "IBM Flex System Chassis Management
Module: Command-Line Interface Reference Guide" at http://
ralfss21.raleigh.ibm.com:8099/help/topic/com.ibm.acc.cmm.doc/
cmm_cli_guide.html.
– IBM Flex System Manager management software is a platform-management
foundation that streamlines the way you manage physical and virtual systems
