Technical Overview
Engineering breakdown of Mastering NVMe Storage Arrays with RAID-10 (8171). Bare-metal hardware performance requires isolated kernel parameters, tuned I/O schedulers, and careful NUMA placement. This article walks through the full stack: from PCIe lane allocation and controller firmware versions to mdadm RAID‑10 layout, write‑back cache policies, and end‑to‑end latency profiling.
Key Design Decisions
- PCIe Topology: 4× NVMe drives per CPU socket, each on a dedicated x4 lane.
- RAID‑10 Stripe Size: 256 KiB aligned to the NVMe namespace block size.
- Write‑Back Cache: Enabled on the controller with battery‑backed cache (BBC) to survive power loss.
- IRQ Affinity: Each queue pair pinned to a dedicated core on the same NUMA node.
