All tests performed on both Intel and AMD platforms, OCP 4.18 or above.
Testing is performed with different storage configurations, such as:

• ODF (Block)
• Pure Storage (CSI) iSCSI
• Pure Storage (CSI) FC

3. Detailed Implementation Guides

Select the specific configuration below for deep-dive technical requirements (Networking, YAML snippets, and Tuning):

A. Oracle 19c Standalone

• Storage: ODF via RBD (Block mode)
• Key Tuning: HugePages (2MB), VirtIO-SCSI multiqueue.
• Details here

B. Oracle 19c RAC (Real Application Clusters)

• Interconnect: Secondary Networks via Multus (SR-IOV recommended).
• Shared Storage: Requires ReadWriteMany (RWX) Block volumes.
• Details here

C. Pure Storage Integration

• DirectFlash Fabric: Using Pure Storage FlashArray via Fiber Channel or iSCSI.
• Findings: Sub-millisecond latency validation and snapshot integration.
• [Link to Pure Storage Setup Guide]

4. Known Issues and Limits

• MTU Settings: Ensure consistent MTU (9000 recommended) across the RAC private interconnect.
• IOPS Limits: Review default QEMU disk throttling if performance fluctuates.

5. Change Log (Adding New Configurations)

• Mar 2026: Added Oracle 26ai testing results on RHEL 9.
• Feb 2026: Added Oracle 26ai preliminary testing results on RHEL 8.
• Dec 2025: Initial publication of RAC performance validation with Pure Storage.
