The SAP HANA database can be deployed as SAP offering in-memory appliance or the SAP HANA tailored data center integration (TDI) approach. SAP HANA sizing refers to regulating the prerequisites for explicit SAP HANA establishment requirements for hardware. CPU, memory (RAM), and hardware disks are important from the sizing perspective. In SAP HANA, the user can perform sizing either using an  ABAP report, quick sizer tool, or DB script based on the scenario.
