Since SAP introduced the TDI deployment model, two certification scenarios have been used to test the performance of the SAP HANA persistence (data and log) and validate that the storage array meets the SAP KPIs for bandwidth (MB/s) and latency (microseconds): HANA-HWC-ES 1.0 and HANA-HWC-ES 1.1.
With SAP HANA 1.0 SPS 10 and higher, SAP introduced a new scenario for enterprise storage certifications. Version 1.1 now uses the underlying file system performance tool (fsperf) for file system performance validation. With fsperf, random I/O operations required additional resources and the KPIs could be achieved only with more disks (HDDs) or flash disks.
- The Unity all-flash and hybrid arrays for both the x00(F) and the x50F models have been certified using HANA-HWC-ES 1.1. All configuration and scalability recommendations in this document are based on this scenario. When re-validating Unity all-flash and hybrid arrays at a customer site, see SAP Note 1943937: Hardware Configuration Check Tool - Central Note.
