How does SAP sizing affect SAP HANA pricing?

Whether you are opting for HANA on premises or cloud, database server main memory size will affect your pricing. Here are some basics to understand as your start your research.

SAP HANA pricing is based on the SAP "T-shirt size," which is based on database size and defined by SAP. The table...

below shows T-shirt sizes for different HANA database server main memory sizes. SAP uses T-shirt sizing to simplify sizing and hardware configurations, and in turn, reduce complexity.

When it comes to assessing the server main memory sizing needed for SAP HANA on premises versus cloud, it's important to factor in potential future database growth along with the flexibility to scale up or down as needed.

Let's now quickly evaluate how sizing differs from an on-premises scenario to HANA cloud.

 T-Shirt Size  SAP HANA Database Server Main Memory
 XS  128 GB
 S  256 GB
 M  512 GB
 L  1 TB
 XL  2 TB
 XXL  4 TB
 3XL  6 TB


SAP HANA sizing for cloud -- and in turn, SAP HANA pricing -- has a distinct advantage over on premises since a company can scale up the database or scale it down as needed. This flexibility ensures that the company is only paying for the database it uses. It is prudent to size HANA at 20% of the required database, while for S/4HANA, the recommendation is 10%.

On premises

When sizing a HANA system for HANA on premises, companies will want to set up a system that is more than 100% larger than the sizing estimates recommended by the sizing tool. This ensures there will be enough database memory available to accommodate future database growth without the need for further investment in physical infrastructure. Fortunately, while there are reliable sizing tools available for SAP HANA to make it easier for customers to know the precise database size needed, that isn't the case with SAP S/4HANA -- the application side of SAP HANA -- as it's still a relatively new offering.

Whatever your implementation strategy will be and whether you use SAP or a SAP HANA-certified appliance provider, you'll be advised to take a cautious approach that can also accommodate several years of incremental business transaction growth of a company.
