HANA Sizing - How to reduce the size further?

550 Views

Hi All

We are upgrading our BW system from from 3X to latest 7X and migrating to HANA. Our system size is 2.5TB and we have Stats Cube, Change Logs and PSA tables which are accounting to 1TB. After our housekeeping activities we have reduced the size of our DB to 1.3TB and when we run the HANA sizing report we dont see any impact on the output before and after our housekeeping activities

After we reduced out DB the largest tables that we see are the RSD* tables (ROW Based) and Fact, Active Tables and Change Logs (COL). Should we reduce the Row based tables instead of Col? should we ignore RSD* tables for sizing?

Memory Requirement (Minimum Total): 780GB (Before) 777GB (After)

HANA Sizing Report which was used - /SDF/HANA_BW_SIZING

Selections: Supress tables < 1MB - X, One Table Per RFC - X, Precision - High, Non Active Data - X

PS: We were aiming for 512GB Hardware but it looks like we need more than what we anticipated
