Dynamic Disk Pools (DDP) provide what benefit?

Dynamic Disk Pools (DDP) provide what benefit?

• A. They distribute parity across all drives for fast rebuilds.
• B. They store data in a single parity layout.
• C. They eliminate parity entirely.
• D. They require RAID 0 for speed.

Answer: (A)

Dynamic Disk Pools spread parity information across all disks in the pool instead of pinning it to a single location. This distribution lets the system rebuild a failed drive quickly because the missing data can be calculated from parity spread over many drives, which speeds up the rebuild and reduces the chance of another failure during the process. It also supports mixing different drive sizes more flexibly while maintaining protection. In contrast, a single parity layout would slow rebuilds and be less resilient, eliminating parity would remove protection, and RAID 0 would be fast but offer no data protection. So the main benefit is faster, safer rebuilds through distributed parity.
