Which of the following RAID levels are supported by Dorado V6? (Multiple choice)

Question

Options

• ARAID 10
• BRAID 6
• CRAID 5
• DRAID TP

• A
  100% (31)

Explanation

All four options are correct - Dorado V6 supports RAID 10, RAID 6, RAID 5, and RAID TP, making this an "all of the above" scenario. RAID 10 combines mirroring and striping for high performance and resilience. RAID 5 uses single distributed parity (tolerates 1 drive failure), and RAID 6 extends that with dual parity (tolerates 2 drive failures). RAID TP (Triple Parity) is a Huawei-proprietary RAID level unique to OceanStor/Dorado systems that tolerates 3 simultaneous drive failures, making it especially valuable in large-capacity NVMe flash pools where rebuild times increase risk.

Since no choice is a distractor here, the exam is testing whether you know that RAID TP exists and is Huawei-native - candidates unfamiliar with it might doubt option D and leave it unselected.

Memory tip: Think "5, 6, TP, 10 - Dorado does them all." The progression 5 → 6 → TP represents increasing parity levels (1, 2, 3 drive failures tolerated), and RAID 10 covers the mirroring use case. If you see RAID TP on an exam, it's almost always a Huawei/Dorado question.
