Lenovo Flex System x440 Compute Node Installation And Service Manual page 19

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.
• 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

cmm_ cli_book.pdf.
• 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 Flex System Chassis Management Module (CMM) and the Lenovo
XClarity Administrator or Flex System Manager management software (if available).
– 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
Command-Line Interface Reference Guide at http://pic.dhe.ibm.com/infocenter/flexsys/information/
topic/com.lenovo.acc.cmm.doc/dw1kt_cmm_
– The Lenovo XClarity Administrator is a virtual appliance that you can use to manage Flex System
chassis in a secure environment. The Lenovo XClarity Administrator provides a central interface to
perform the following functions for all managed endpoints:
– User management
– Hardware monitoring and management
– Configuration management
– Operating system deployment
– Firmware management
For more information, see
– 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, Flex System Manager management software supports multiple operating systems and
virtualization technologies. For more information, see
