# NVMe over Fabrics Host Support {#nvme_fabrics_host}
|
|
|
|
The NVMe driver supports connecting to remote NVMe-oF targets and
|
|
interacting with them in the same manner as local NVMe controllers.
|
|
|
|
# Specifying Remote NVMe over Fabrics Targets {#nvme_fabrics_trid}
|
|
|
|
The method for connecting to a remote NVMe-oF target is very similar
|
|
to the normal enumeration process for local PCIe-attached NVMe devices.
|
|
To connect to a remote NVMe over Fabrics subsystem, the user may call
|
|
spdk_nvme_probe() with the `trid` parameter specifying the address of
|
|
the NVMe-oF target.
|
|
The caller may fill out the spdk_nvme_transport_id structure manually
|
|
or use the spdk_nvme_transport_id_parse() function to convert a
|
|
human-readable string representation into the required structure.
|
|
|
|
The spdk_nvme_transport_id may contain the address of a discovery service
|
|
or a single NVM subsystem. If a discovery service address is specified,
|
|
the NVMe library will call the spdk_nvme_probe() `probe_cb` for each
|
|
discovered NVM subsystem, which allows the user to select the desired
|
|
subsystems to be attached. Alternatively, if the address specifies a
|
|
single NVM subsystem directly, the NVMe library will call `probe_cb`
|
|
for just that subsystem; this allows the user to skip the discovery step
|
|
and connect directly to a subsystem with a known address.
