NVMe/TCP Makes iSCSI Look like Fortran
summary
Claim: replacing iSCSI with NVMe/TCP nearly doubles read/write IOPS and cuts per‑packet overhead by ~25%, using standard Linux kernel NVMe stack over commodity Ethernet. Demonstrations compare latency and throughput on 100Gb links, note AWS Linux 2 required kernel fixes, and show multipath failover, remote boot demos and Proxmox integration. A storage system is built around NVMe/TCP with a CSI driver and S3-backed block snapshots for point‑in‑time recovery, and it works in benchmarks.
