High-Efficiency Data Protection on Energy-Efficient Servers: Getting PCIe Gen5 Performance Without the Power-Hungry CPU Cores

PCIe Gen5 NVMe SSDs are now fast enough that parity RAID frequently becomes CPU-bound, pushing teams toward high-frequency, power-hungry processors just to keep pace. Meanwhile, power has become one of the tightest constraints in modern data centers. This talk shares results from a joint Xinnor & Intel validation asking whether energy-efficient CPU cores (Intel Xeon 6 E-cores) can realistically drive high-end NVMe storage performance without compromising latency or predictability.We present benchmark results and the reasoning behind them: how different I/O processing approaches shift the trade-off between peak IOPS and tail latency, why interrupt coalescing can dramatically boost random read throughput while introducing large latency penalties, and how a user-space polling datapath avoids that compromise. Using an 8x PCIe Gen5 NVMe setup, we compare RAID6 and RAID10 across Intel Xeon E-cores and P-cores, translating findings into practical design guidance for building performance-per-watt-optimized NVMe servers and NVMe-oF building blocks.
