Which configuration reduces rebuild time and minimizes performance impact for streaming workloads on an E-Series array?

• A. RAID 6
• B. RAID 10
• C. Thin-provisioned volumes
• D. Dynamic Disk Pools

Answer: (D)

Dynamic Disk Pools keep disks organized into separate, independent pools, each with its own rebuild capabilities. When a drive fails, the rebuild happens within the pool that contains that drive, using the pool’s spare resources. This containment means the rest of the array keeps servicing streaming workloads with less disruption, so the rebuild completes faster overall and with lower impact on throughput and latency for the streaming traffic. RAID choices like RAID 6 or RAID 10 introduce parity or mirroring overhead and can slow down rebuilds or waste capacity, which doesn’t specifically optimize rebuild time for streaming workloads. Thin provisioning focuses on capacity efficiency, not on how rebuilds affect performance.
