What is NVMe over TCP in practical terms?
It is a way to extend NVMe block-storage semantics across standard TCP/IP networks so teams can build shared storage systems with modern protocol behavior over common Ethernet infrastructure.
Use Case
NVMe over TCP Storage for OpenShift and Kubernetes
Use standard Ethernet to deliver low-latency block storage without carrying forward older protocol and fabric assumptions.
NVMe over TCP is a key proof point in simplyblock's architecture for OpenShift, Kubernetes, and VMware-exit storage programs. It gives platform teams a modern block-storage data path over commodity networking while keeping room for hyper-converged, hybrid, and disaggregated deployment models. This page is the architectural proof layer, not the main commercial entry point.

The Architecture Question
Why Teams Evaluate NVMe over TCP
Platform teams need a block-storage protocol that fits cloud-native infrastructure economics and operational models, not just raw benchmark slides.
Older Protocols Add More Operational Overhead
Teams want modern block-storage performance without designing around older storage-network assumptions or specialized fabrics.
Scale-Out Architectures Need a Better Data Path
Shared storage for Kubernetes, OpenShift, and virtualized workloads needs a protocol that fits distributed systems over standard networking.
VMware Exit Programs Need a Modern Replacement Foundation
When teams leave vSAN-era architecture behind, the storage protocol choice becomes part of the broader platform design.
Workloads Still Need Low-Latency Block Storage
Databases, KubeVirt virtual machines, and other stateful services still care deeply about latency, throughput, and predictable behavior.
Why It Matters
How NVMe over TCP Supports the Simplyblock Architecture
A protocol choice that fits OpenShift and Kubernetes storage instead of fighting the way those platforms operate.
Use Standard Ethernet for Modern Block Storage
NVMe over TCP brings NVMe semantics over widely available TCP/IP networks. That lowers adoption friction and avoids forcing teams into special-purpose networking before the workload and platform model are even settled.
- Use standard networking instead of a dedicated storage fabric
- Reduce protocol overhead compared with older approaches
- Keep adoption practical for enterprise platform teams
- Fit cloud, private-cloud, and on-prem deployment models
Support HCI, Hybrid, and Disaggregated Storage Models
NVMe over TCP works as part of simplyblock's broader storage architecture, which is why it fits OpenShift HCI, broader OpenShift storage, and later disaggregated growth on the same foundation.
- Start hyper-converged when operational simplicity matters most
- Move toward hybrid or disaggregated when scale changes
- Keep one storage foundation across operating shapes
- Avoid treating protocol choice and deployment model as separate projects
Fit VMware-Exit, OpenShift, and KubeVirt Programs
NVMe over TCP matters because it supports low-latency block storage for both containers and virtual machines without depending on a hypervisor-bound storage stack. That makes it an important proof layer for VMware Migration to OpenShift and Kubernetes and KubeVirt Storage.
- Support VM disks and persistent volumes on one storage platform
- Keep architecture aligned with Kubernetes-native operations
- Avoid carrying forward older datastore assumptions
- Improve protocol fit for modern private-cloud platforms
What Teams Gain
Outcomes of Choosing NVMe over TCP
A cleaner architectural fit for modern block storage, especially in OpenShift-led and VMware-exit platform work.
Low-Latency Block Storage Over Standard Networks
Get a modern storage data path without introducing a specialized networking dependency as the default answer.
Better Architectural Fit for Cloud-Native Platforms
Align storage more naturally with OpenShift and Kubernetes operating models.
Scale-Out Ready
Support distributed architectures that need more than host-local storage without reverting to legacy protocol assumptions.
Useful for VMware Exit and vSAN Replacement
Use NVMe over TCP as one of the technical foundations behind a cleaner replacement architecture.
Workload Fit for Stateful Services
Keep the protocol aligned with the needs of databases, KubeVirt, and other storage-sensitive workloads.
Broad Linux and Platform Compatibility
Fit modern infrastructure environments without making client integration unnecessarily exotic.
Questions and Answers
Why does NVMe over TCP matter for OpenShift and Kubernetes?
Because those platforms need low-latency block storage that fits distributed systems and cloud-native operations. NVMe over TCP is a strong protocol fit for that requirement set.
Does this page replace the main OpenShift storage story?
No. This is the proof page for one architectural layer. The broader commercial story lives in OpenShift Storage, Hyper-Converged Storage for OpenShift, and VMware Migration to OpenShift and Kubernetes.
Do teams need special networking hardware to benefit from NVMe over TCP?
No. One of the advantages is that it runs over standard TCP/IP networking, which keeps adoption practical and avoids making every storage decision depend on a specialized fabric choice.
How does NVMe over TCP relate to software-defined storage?
Software-defined storage is the broader architecture model. NVMe over TCP is one of the key protocol choices that lets that architecture deliver low-latency shared block storage over standard Ethernet.
