The SAP HANA platform combines SAP software components that are optimized on partner-provided proven and certified hardware. Two models are available for on-premises deployment, as shown in the following figure:
By default, an SAP HANA appliance includes integrated storage, compute, and network components. The appliance is certified by SAP, built by an SAP HANA hardware partner such as Dell Technologies, and shipped to customers with all its software components preinstalled, including the operating systems and SAP HANA software.

Customers using the SAP HANA TDI deployment model can choose from a broad portfolio of SAP HANA-certified servers to combine with SAP-certified network and storage components. Different workloads can share the components to optimize the total cost of ownership (TCO). Customers can seamlessly integrate SAP HANA into existing data center operations such as disaster recovery, data protection, monitoring, and management, reducing the cost, time-to-value, and risk of an overall SAP HANA adoption.
