The PowerFlex system uses checksums to protect data that transits through the system. You can enable the checksum feature at the protection domain level and define it at the storage pool level. Depending on the type of workload, the checksum feature can have a significant impact on the performance.
SAP does not require a checksum feature for SAP HANA on the storage subsystem—the PowerFlex system, in this case. SAP HANA uses its own checksums to protect data that is stored on the persistence layer.
For the highest data protection requirements, the PowerFlex checksum feature is supported and can be enabled on the storage pool that is used for the SAP HANA persistence.
