SAP HANA on VMware vSphere – Sizing (Compute)
This is the second blog of my SAP HANA on vSphere blog series and will provide information on SAP HANA on VMware vSphere compute resource sizing.This blog does not describe how to perform the actual SAP HANA system RAM sizing. For this please refer to the SAP documentation. A good start is to read the sizing SAP HANA Sizing Approaches presentation, which describes the SAP HANA QuickSizer and ABAP SAP HANA sizing reports available for sizing SAP HANA systems. Also a good start is the Sizing Approaches for SAP HANA document. (Attention you may require a SAP SDN account to access the SAP HANA sizing presentation).
CPU and RAM Sizing SAP HANA on VMware vSphere
Sizing SAP HANA is different from sizing a classical SAP application. Instead focusing on CPU resources, for SAP HANA memory is the focus and how many CPU resources are required to support a specific amount of RAM. Beside this, we have to consider the different CPU and RAM maximums of vSphere 5.5 and 6, as it defines the maximal size of a virtual SAP HANA VM. To make it even more complex, we have to take into account which workload (SoH or BWoH) will run on the selected SAP HANA system, which CPU and which HANA SPS version will get used, as different CPU socket to RAM ratios exist for all of these combinations.
