Verification: conference paper PDF, DOI metadata, and arXiv preprint; confidence=high. Canonical title: KVACCEL: A Dual-Interface SSD Architecture for Key-Value Storage Acceleration Question: Can one SSD support both block and key-value paths while accelerating LSM-tree writes without violating consistency? Context: Host-managed LSM stores suffer write stalls and overhead, while KV SSDs alone do not preserve the conventional block interface. Method: KVACCEL partitions NAND between block and KV interfaces, uses the KV region as a temporary write buffer, and adds an in-device LSM buffer plus range-scan iterator. Evaluation: workloads=write-intensive and mixed read/write key-value workloads; baselines=ADOC and conventional paths; metrics=throughput and CPU efficiency; results=up to 17% throughput gain on write-intensive workloads; comparable mixed-workload performance Interpretation: A KV namespace can act as a pressure-relief tier for the host LSM while block compatibility is retained. Reusable lesson: Use device interfaces according to data lifetime and write-path urgency, with an explicit reconciliation protocol. Applicability: LSM-based stores on programmable dual-interface SSDs. Limits: Requires modified dual-interface SSD firmware; the headline gain is for write-intensive workloads.
