Explanation
Dynamic Pool Configuration with RAID 5: RAID 5 (4+1) protection involves 4 data drives and 1 parity drive. Minimum Drive Count: For creating a dynamic pool with RAID 5 (4+1), the configuration must include at least 2 RAID 5 (4+1) groups to ensure redundancy and performance. The minimum drive count for this setup would be 2 * (4 + 1) + 1 (hot spare) = 11 drives. RAID 5 Requirements: This configuration ensures that the dynamic pool has enough drives to maintain performance and data protection according to Dell's best practices.
