Size your BW on SAP HANA System
Determining needed hardware resources is usually done by the SAP hardware partner based on order information you submit. You provide this information using the SAP HANA In-Memory DB Sizing Guideline attached to SAP Note 1514966, SAP HANA 1.0: Sizing SAP In-Memory Database. SAP Note 1514966 also contains a script get_size.zip which will assist in calculating the data footprint of the SAP systems.
Alternatively, use the SAP QuickSizer tool to calculate the system memory requirements for your business warehouse data. You will find a questionnaire specifically for SAP NetWeaver BW powered by SAP HANA in this tool.
This table offers rough estimates of system hardware needs.
