System Management
ASMe integrates system management features into the hardware and
provides additional features through ASMe Server Management
software. This section describes the integrated hardware features, Acer
Advance Server Management software, and the System Setup Utility
and FRU/SDR Load Utility used to configure the hardware features.
Baseboard Management Controller
Acer server boards incorporate a baseboard management controller
(BMC), which is a dedicated microcontroller for system management
activities. The BMC performs the following functions:
• Monitors system components and sensors, including processors,
memory, fans, power supplies, temperature sensors, and chassis
intrusion sensors.
• Manages nonvolatile storage for the system event log (SEL), sensor
data records (SDRs), and baseboard field-replaceable unit (FRU)
inventory.
• Interfaces with the emergency management port (EMP) and LAN1
port to send alerts and interact with remote management systems.
• Provides the main front panel control functions (power on/off,
reset, and so on).
Field Replaceable Units and Sensor Data Records
Field replaceable units (FRUs) are major modules in the chassis that
contain active electronic circuitry. FRUs can store information-such as
board serial number, part number, name, and asset tag-that can be
read using the System Setup Utility (see “Viewing FRU Information” on
page 64). The BMC stores FRU information for the baseboard in a
nonvolatile storage component on the board.
The BMC uses Sensor Data Records (SDRs) to identify the sensors in the
system for monitoring. SDRs provide a list of the sensors, their
characteristics, location, type, and type-specific information, such as
default threshold values, factors for converting a sensor reading into
the appropriate units (mV, rpm, degrees Celsius), and information on
the types of events that a sensor can generate. The BMC stores SDR
information in a nonvolatile storage component on the baseboard.
