NVMe over TCP is incompatible with VMware ESXi environments. TrueNAS uses the Linux kernel NVMe over TCP target driver, which lacks support for “fused commands” required by VMware ESXi. This is an upstream kernel limitation that prevents path initialization in ESXi environments.
After configuring a NVMe-oF subsystem, you can change the subsystem by adding or deleting a namespace, removing or adding a port, or adding, removing, or deleting a host.
The NVMe-oF screens provide access to screens, widgets, settings, and dialogs to add, manage, or delete NVMe over Fabric subsystems (targets). NVMe-oF (NVMe over Fabric) is a specification that extends NVMe storage access over network fabrics like Ethernet, Fibre Channel, and InfiniBand. It allows hosts to access NVMe storage remotely while maintaining the high performance and low latency benefits of NVMe.
The NVMe-oF Subsystems widget shows on the Shares screen. The header shows the status of the NVMe service as Stopped or Running, the Add button, and the dropdown menu with two options:
