VxFlex OS uses checksums to protect data that transits through the VxFlex OS 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 VxFlex OS, 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 VxFlex OS checksum feature is supported and can be enabled on the storage pool that is used for the SAP HANA persistence.
