Memory requirements

  • SAP has restrictive requirements for the physical memory configuration of an SAP HANA server. These restrictions also apply to virtualized servers such PowerFlex nodes. A symmetric, homogeneous assembly of Dual In-Line Memory Modules (DIMMs) (the memory chips in the server) with maximum utilization of all memory channels per processor is required. Figure 2 and Figure 3 show the permitted configurations of the PowerFlex nodes for SAP HANA.

    The following figure shows the supported DIMM/memory configurations for R640 and R740xd servers:
