The Complete Guide to NVMe/TCP Storage Networking
NVMe/TCP delivers sub-40µs latency and millions of IOPS over standard Ethernet — no special hardware, no proprietary fabric. Learn how it works, how it compares, and how to deploy it.
What is NVMe/TCP?
NVMe/TCP (NVMe over TCP) transports the NVMe command set across standard TCP/IP networks — giving you flash-native performance without proprietary fabrics or special NICs.
NVMe in Kubernetes: Why Latency Matters
How NVMe/TCP Works
NVMe/TCP encapsulates NVMe commands inside TCP segments and sends them over any IP network. An initiator (the host accessing storage) opens a TCP connection to a target (the storage node) and issues I/O using the full NVMe command set — including 64K queues and 64K commands per queue.
NVMe Protocol — built for flash
Massively parallel command queues and a simplified command set designed from scratch for solid-state storage, unlike legacy SCSI-derived protocols.
TCP Transport — runs on existing infrastructure
Uses the standard TCP/IP stack. Any 10GbE+ Ethernet switch and standard NIC is sufficient — no RDMA NICs, no Fibre Channel HBAs, no lossless fabric required.
Disaggregated architecture — scale independently
Compute and storage are fully separated. Add storage capacity or compute nodes independently, enabling flexible and cost-efficient cloud-native architectures.
