SAP HANA Database Sizing

Hi,

We are planing to convert our database to SAP HANA. I just want to know the SAP  HANA hardware requirements for this specific scenario.

Current Database:

Database Type = RDBMS

Disk Usage      = 1.5T

Memory           = 100GB

What are DIsk/Memory requirements for HANA database for this situation?

Thank You.
