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:
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 HANA 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, data protection, monitoring, and management, reducing the time-to-value, costs, and risk of an overall SAP HANA adoption.
SAP has certified Dell EMC PowerMax storage arrays as meeting all performance and functional requirements for SAP HANA TDI deployments. This means that customers can use PowerMax arrays for SAP HANA TDI deployments in a fully supported environment with their existing data center infrastructures.
Using the SAP HANA Hardware Configuration Check Tool (hwcct), Dell EMC engineers performed extensive testing on the PowerMax family of products in accordance with the SAP HANA-HWC-ES-1.1 certification scenario. From these tests, we derived storage configuration recommendations for the PowerMax arrays that meet SAP performance requirements and ensure the highest availability for database persistence on disk.
