Dell EMC recommends that SAP HANA solutions have a homogenous, symmetrical assembly of DIMMs and maximum utilization of all memory channels per processor. In accordance with this recommendation, two-socket servers must be populated with at least 12 DIMMs, and four-socket solutions must have at least 24 DIMMs.
The following figures show the optimal DIMM size and count for all possible memory permutations:
