This test case shows the performance of Oracle 21c database instances using Dell APEX Block Storage for 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 I/O throttled. With the six PowerFlex SDS instances, the PowerFlex total and free storage capacity is 163.8 TB and 100 TB respectively.
We created four ASM disk groups for the Oracle database:
