In addition to the CPU and memory requirements for the SAP HANA VMs, consider the CPU and memory requirements for the vSphere hypervisor and VxFlex OS. For the hypervisor, add 10 percent of the CPU resources to the SAP HANA CPU requirements to account for the vSphere overhead. The VxFlex OS SDS requires one CPU socket on each physical node for the VxFlex OS storage VM (SVM). SAP does not allow sharing of this socket with production SAP HANA VMs.
Customers can order VxFlex with four-socket nodes (the R840 server) and two-socket nodes (R640 and R740xd servers).
These restrictions apply to production SAP HANA VMs only. Nonproduction SAP HANA VMs or non HANA VMs can share a CPU socket with the VxFlex OS SVM.
VxFlex nodes for SAP HANA require Intel silver, gold, or platinum CPU models offering different clock speeds and core counts. VxFlex allows the installation of half-socket SAP HANA VMs, while the smallest configurable SAP HANA VM requires at least eight physical cores. Consider using CPUs with at least 16 cores in the VxFlex nodes for half-socket SAP HANA VM deployments.
