3.2.4 Sensor Data Record SDR (SDR) Repository
The BMC implements a logical Sensor Data Record (SDR) repository device. The SDR
repository is accessible via all communication transports, even while the system is powered off.
3.2.5 Field Replaceable Unit (FRU) Inventory Devices
The BMC implements the interface for logical FRU inventory devices. 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 Table 9 and SMBus
connectivity shown in Figure 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 main board. All Intel-designed server
boards maintain onboard non-volatile storage to hold the FRU data.
