This test case shows the performance of Oracle 19c database instances using PowerFlex volumes running in AWS. The PowerFlex storage pool uses the Amazon instance store with four x 7.5 TB NVMe SSD drives on each PowerFlex SDS instance. The number and size of NVMe SSD drives per instance are based on the PowerFlex SDS instance type selection. The NVMe SSD drive throughput is not shared with other instances, hence, no I/O reservation is necessary nor is IO throttled. With the six PowerFlex SDS instances, the PowerFlex total and free storage capacity is 163.8 TB and 100 TB respectively.
Four ASM disk groups were created for the Oracle database:
