Intel SE7520BD2 Technical Product Specification

Platform Management ArchitectureIntel® Server Board SE7520BD2 Technical Product Specification
92 Revision 1.3
If the RTC changes during system operation, system management software must synchronize
the mBMC time with the system time. If this is not done, the server should be reset so that the
BIOS will pass the new time to the mBMC.
4.2.10 Sensor Data Record (SDR) Repository
The mBMC includes built-in Sensor Data Records that provide platform management
capabilities (sensor types, locations, event generation and access information). The SDR
Repository is accessible via all communication transports. This way, out-of-band interfaces can
access the SDR Repository information if the system is down.
The mBMC supports 2176 bytes of storage for SDR records. The SDR defines the type of
sensor, thresholds, hysteresis values and event configuration. The mBMC supports up to six
threshold values for threshold-based full sensor records, and up to 15 events for non threshold-
based full and compact sensor records. It also supports both low-going and high-going sensor
devices.
4.2.10.1 SDR Repository Erasure
TBD
4.2.10.2 Initialization Agent
The mBMC implements the internal sensor initialization agent functionality specified in the
Intelligent Platform Management Interface Specification, Version 1.5. When the mBMC
initializes, or when the system boots, the initialization agent scans the SDR repository and
configures the sensors referenced by the SDRs. This includes setting sensor thresholds,
enabling/disabling sensor event message scanning, and enabling/disabling sensor event
messages.
4.2.11 Event Message Reception
The mBMC supports externally (e.g., BIOS) generated events via the Platform Event Message
command. Events received via this command will be logged to the SEL and processed by PEF.
4.2.12 Event Filtering and Alerting
The mBMC implements the following IPMI 1.5 alerting features:
• PEF
• Alert over LAN
4.2.12.1 Platform Event Filtering (PEF)
The mBMC monitors platform health and logs failure events into the SEL. The Platform Event
Filtering feature provides a configurable mechanism to allow events to trigger alert actions. PEF
provides a flexible, general mechanism that enables the mBMC to perform selectable actions
triggered by a configurable set of platform events. The mBMC supports the following IPMI PEF
actions:
• Power-down
• Soft shut-down
• Power cycle
