Breaking Storage Bottlenecks with NVMe-oF
Datacore, Monday, November 10th, 2025
Exploring the technical foundations, transport trade-offs, and architectural shifts that make NVMe-oF essential for next-generation infrastructures
Latency has always been the Achilles' heel of storage networking. With spinning disks, a few milliseconds of delay didn't matter much because the physical media itself was slow. But once flash and SSDs entered the picture, the bottleneck shifted from the device to the protocol stack and the network. Even with locally attached NVMe SSDs, applications can complete I/O in tens of microseconds. Contrast that with traditional SAN protocols like iSCSI or FCP, where each I/O might incur hundreds of microseconds of software and network overhead. That gap is precisely what NVMe-oF addresses.
