HANA scale-out is unlike other database platforms, it can be simple but complex at the same time. Depending on the scenario, the in-memory nature of HANA services, the persistence layers, and optional multi-tenancy (Multi-tenant Database Container - MDC), it can get complicated pretty fast. The table distribution across systems and table partitioning can further add to the complexity. In the next several publications, we'll set out to cover the installation, configuration, testing, and SAP HANA monitoring in scale-out, HA, DR with HANA System Replication, and Extended storage management with HANA Dynamic Tiering.
