Dell Device Names (Type 225)

Source: reverse engineered from the dumps of the data corpus.

Gives the devices of a kind the names the management controller (iDRAC) of a PowerEdge server knows them by, its fully qualified device descriptors (FQDD), e.g. CPU.Socket.1 and CPU.Socket.2 to the processors (type 4) of handles 0x0400 and 0x0401, or DIMM.Socket.A1 to the memory device (type 17) of handle 0x1100 in dell/poweredge-r640.bin. The structures are found on PowerEdge servers of the 13th and 14th generations, one for the processors and one for the memory devices.
