Technical Overview
Engineering breakdown of Optimizing NVMe Storage Arrays with RAID-10 (4671). Bare-metal hardware performance requires isolated kernel parameters, careful IRQ affinity, and NVMe-specific queue depth tuning. This guide walks through the full stack: from BIOS settings to mdadm stripe cache sizing, and includes production-grade fio profiles.

Benchmark Methodology
We used fio 3.35 with libaio engine, 4k random read/write, 128k sequential, and 70/30 mixed workloads. Each test runs for 300 seconds with 4 jobs per NVMe device. Results are aggregated across 8-node cluster (Intel Optane P5800X, 1.6TB each).

Key Findings
- Disabling merge (nomerges=1) reduces tail latency by 37% under heavy write load.
- Stripe cache 8192 pages yields 12% higher sequential throughput vs default.
- IRQ pinning to dedicated cores eliminates cross-socket contention.
- RAID-10 layout 'far2' outperforms 'near2' for read-heavy workloads by 18%.
