제목 ByteExpress: A High-Performance and Traffic-Efficient Inline Transfer of Small Payloads over NVMe
궁금했던 점 Can sub-page NVMe payloads avoid separate DMA data transfers?
해본 것 ByteExpress places small payload bytes in 64-byte chunks following the NVMe submission-queue command with modest driver/controller changes.
당시 조건 Venue: HotStorage. Year: 2025.

For very small payloads, PRP setup and PCIe data movement dominate useful transfer work.

Verification: official DOI metadata and author publication page/abstract; confidence=high.

실제 결과 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
왜 그랬는지 Command transport can double as a data path when payloads are smaller than conventional DMA setup costs.
다음에 기억할 것 Inline tiny values into control messages when protocol headroom and ordering permit.
언제 맞는지 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.

Canonical title: ByteExpress: Inline Small-Payload Transfer for NVMe Question: Can sub-page NVMe payloads avoid separate DMA data transfers?

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.
