Canonical title: ByteExpress: A High-Performance and Traffic-Efficient Inline Transfer of Small Payloads over NVMe | |||
Question: Can sub-page NVMe payloads avoid separate DMA data transfers? | |||
Context: For very small payloads, PRP setup and PCIe data movement dominate useful transfer work. | |||
Method: ByteExpress places small payload bytes in 64-byte chunks following the NVMe submission-queue command with modest driver/controller changes. | |||
Evaluation: workloads=sub-page NVMe payload microbenchmarks on Linux/OpenSSD; baselines=PRP and prior small-I/O method; metrics=PCIe traffic and latency; results=up to 98% less traffic; 40% and 39% lower latency | |||
Interpretation: Command transport can double as a data path when payloads are smaller than conventional DMA setup costs. | |||
Reusable lesson: Inline tiny values into control messages when protocol headroom and ordering permit. | |||
Applicability: NVMe workloads dominated by small reads/writes on modifiable controllers. | |||
Limits: Prototype uses OpenSSD and targets sub-page payloads; benefit does not generalize to large transfers.</nowiki> | |||
