Detailed Explanation:

Rationale for Correct Answer:

HPE Alletra 6000 is a scale-out architecture array. Adding more arrays to a single scale-out group increases both performance (IOPS, throughput) and capacity, while maintaining single-pane management via HPE Data Services Cloud Console. This is the most efficient way to address both capacity growth and latency reduction for SQL workloads.

Distractors:

B: Adding NICs may help with throughput but not backend latency or capacity scaling.

C: Flash-to-cache ratios can optimize read caching but don’t fundamentally increase system-wide performance.

D: Timeless storage is a procurement/licensing option, not a performance/capacity scaling method.

Key Concept: Alletra 6000 scale-out clustering for balanced growth of capacity and performance.
