Because Dell’s SAP HANA solutions are on scalable building blocks, you can easily add blocks of 4.5 TB, 9 TB, or 12 TB to scale out to a 96 TB solution. SAP HANA certified enterprise storage components for Dell storage arrays with dual redundant controllers provide the persistent storage for the SAP HANA database. All components, including storage, fabric, network, and controllers, are highly redundant.
