Platform Management
Intel® Server Board SE7320VP2
access. The message-based interface isolates software from the particular hardware
implementation.
System Management Software discovers the platform’s sensor capabilities by reading the
Sensor Data Records from a Sensor Data Record Repository managed by the management
controller. Sensor Data Records provide a list of the sensors, their characteristics, location,
type, and associated Sensor Number, for sensors in a particular system. The Sensor Data
Records also hold default threshold values (if the sensor has threshold based events), factors
for converting a sensor reading into the appropriate units (mV, rpm, degrees Celsius, etc.), and
information on the types of events that a sensor can generate.
Sensor Data Records also provide information on where Field Replaceable Unit (FRU)
information is located, and information to link sensors with the entity and/or FRU they’re
associated with.
Information in the SDRs is also used for configuring and restoring sensor thresholds and event
generation whenever the system powers up or is reset. This is accomplished via a process
called the ‘initialization agent’. The mBMC reads the SDRs and based on bit settings, writes the
threshold data. Then it enables event generation for the various sensors it.
System Management Software uses the data contained in the Sensor Data Record information
to locate sensors in order to poll them, interpret, and present their data readings, adjust
thresholds, interpret SEL entries, and alter event generation settings.

Management Controllers
At the heart of platform management is a management controller. The Server Board
SE7320VP2 supports the PC87431M mini-Baseboard Management Controller (mBMC) from
National Semiconductor.
The management controller is a microcontroller that provides the intelligence at the heart of the
Intelligent Platform Management architecture. The primary purpose of the management
controller is to autonomously monitor system sensors for system platform management events,
such as over-temperature, out-of-range voltages, etc., and log their occurrence in the non-
volatile System Event Log. This includes events such as over-temperature and over-voltage
conditions, fan failures, etc. The management controller also provides the interface to the
sensors and SEL so System Management Software can poll and retrieve the present status of
the platform. The contents of the log can be retrieved ‘post mortem’ to provide failure analysis
information to field service personnel. It is also accessible by System Management Software,
®
such as Intel
Server Management (ISM), running under the operating system.
The management controller includes the ability to generate a selectable action, such as a
system power-off or reset, when a match occurs to one of a configurable set of events. This
capability is called Platform Event Filtering, or PEF.
The management controller includes recovery control functions that allow local or remote
software to request actions such as power on/off, power cycle, and system hard resets, plus an
IPMI Watchdog Timer that can be used by BIOS and/or run-time management software as a
way to detect software hangs.
