SAP HANA production systems in TDI environments must meet the SAP KPIs for storage performance. These systems demand high availability and redundancy in storage and network components such as network cards (HBAs and NICs), network switches, and storage FE components. The SAP HANA database operations must not be affected if one of the components fails.
The following sections of this design guide provide configuration recommendations and best practices for the networks and storage array, based on the connectivity option that is being used for the SAP HANA production systems.
