SAP HANA is an in-memory data platform that can be deployed on-premises (locally) or in the cloud. Organizations use the SAP HANA platform to analyze large volumes of data and develop and deploy applications in real time. The SAP HANA database is at the core of this data platform.
The SAP HANA system combines SAP software components that are optimized on proven, SAP partner-provided hardware. Two models are available for on-premises deployment, as shown in the following figure:
Figure 1. SAP HANA appliance model and TDI model comparison
An SAP HANA appliance includes integrated storage, compute, and network components by default. The appliance is certified by SAP, built by one of the SAP HANA hardware partners, and shipped to customers with all its software components preinstalled, including the operating systems and SAP HANA software.
The SAP HANA appliance model presents customers with the following limitations:
The SAP HANA servers in a TDI model must be certified by SAP and meet the SAP HANA requirements, but the network and storage components, including arrays, can be shared in customer environments. Customers can integrate SAP HANA seamlessly into existing data center operations such as disaster recovery (DR), data protection, monitoring, and management, reducing the time-to-value, costs, and risk of an overall SAP HANA adoption.
