The IMC, ISC0, ISC1 and the micro controller of the MMC provide each on-board memory
which can be accessed externally, for example via the BBS software. Three different memory
types are used to store different types of data. The following table provides details.
The IPMI provides a two-channel BT interface towards the host CPU. The 64-byte FIFO of the BT
interface resides in the Glue Logic FPGA. The first channel is used for standard operation
between CPU and IPMC. The second channel is used for system-critical events to bypass the
first channel.
For details about supported IPMI commands as well as Sensor Data Records (SDRs) and Field
Replaceable Unit (FRU) information provided by the IPMC, refer to the
ATCA-F120: Control via
IPMI Programmer's Reference .
