Hitachi Vantara Qualified Professional – VSP Storage Architect — Question 30
What is the recommended RAID level when creating a Hitachi Dynamic Provisioning (HDP) pool?
Answer options
- A. RAID 1
- B. RAID 1+0
- C. RAID 5
- D. RAID 6
Correct answer: B
Explanation
RAID 1+0, also known as RAID 10, is recommended for Hitachi Dynamic Provisioning pools because it combines the benefits of mirroring and striping, ensuring both high availability and performance. RAID 1 provides redundancy but lacks the performance benefits of striping, while RAID 5 and RAID 6 offer data protection but have slower write speeds due to parity calculations.
