Each DCU has four CPU memory units (CMUs) that have two memory boards, two CPU memory processors (CMPs), and 64 DIMM slots.
Each CMU is represented as /System/DCUs/DCU_x/CMU_x in Oracle ILOM where CMU_x ranges from 0 to one less than the maximum number of possible CMUs in a DCU (CMU_0, CMU_1, CMU_2, CMU_3). For DCU_0/CMU_x, x = 0–3. For DCU_1/CMU_x, x = 4-–7, and so on to CMU_15.
Each CMP is represented as /System/Processors/CPUs/CPU_x in Oracle ILOM where CMP_x ranges from 0 to 31. The CMP targets have a location property that corresponds to the CMU/CMP pair. For example, location might equal CMU0/CMP0 (processor board 0 and host processor 0).
Each DIMM is represented as /System/Memory/DIMMs/DIMM_x in Oracle ILOM.
See this topic for information about viewing information about the installed CMUs.
