5.1.1 Sensor Data Record SDR (SDR) Repository
The BMC implements a logical Sensor Data Record (SDR) repository device, as specified in the
Intelligent Platform Management Interface Specification, Version 2.0. The SDR repository is
accessible via all communication transports, even while the system is powered off.
5.1.2 Field Replaceable Unit (FRU) Inventory Devices
The BMC implements the interface for logical FRU inventory devices, as specified in the
Intelligent Platform Management Interface Specification, Version 2.0. This functionality provides
commands used for accessing and managing FRU inventory information. These commands can
be delivered via all interfaces.
The BMC provides FRU command access to its own FRU device, as well as to the FRU devices
throughout the system. The FRU device ID mappings are shown in Figure 8 and Table 9. The
BMC controls the mapping of the FRU device ID to the physical device. Per the IPMI
specification, FRU device 0 is always located on the Mainboard. By convention, the IMM Board
FRU will always be FRU device 1. All Intel-designed Server boards maintain on-board non-
volatile storage to hold the FRU data.
