Server Management
Most of the server management features are implemented using three microcontrollers, the baseboard management controller (BMC) on the I/O carrier, the front panel controller (FPC) on the front panel board, and the
The primary function of the BMC is to autonomously monitor system platform management events and log their occurrence in the nonvolatile System Event Log (SEL). While monitoring, the BMC maintains the nonvolatile sensor data record repository (SDRR), from which
SEL contents can be retrieved after system failure or during regularly scheduled maintenance. To retrieve SEL contents, field service personnel use tools such as the SSU SEL Viewer or the Intel®Server Control management software.
The BMC:
∙Provides temperature and voltage monitoring
∙Monitors processor presence and performs Fault Resilient Booting (FRB) control
∙Manages SEL interface
∙Manages SDRR interface
∙Manages SDR/SEL timestamp clock
∙Provides Field Replaceable Unit (FRU) information interface
∙Provides system management watchdog timer functions
∙Provides
∙Provides front panel NMI handling
∙Provides event receiver functionality
∙Manages ISA host and Intelligent Platform Management Bus (IPMB) interface
∙Manages secure mode control, front panel lock/unlock initiation, and video blank and diskette write protect monitoring and control
∙Provides sensor event initialization agent
∙ACPI Support
