With SAP HANA Tailored Datacenter Integration (TDI) Phase 5, SAP introduced customer-workload-based system sizing. This sizing method uses SAP Application Performance Standard (SAPS) requirements for specific workloads to determine the type and number of processors that are required to run SAP HANA. Customers use the SAP HANA Quick Sizer tool and sizing reports to size their system, and share the results with Dell Technologies to determine the optimal number of VxRail nodes, CPU types, and memory sizes for their SAP HANA environment.
