NAME nvd — NVM Express disk driver
SYNOPSIS To compile this driver into your kernel, place the following lines in your kernel configura‐ tion file: device nvme device nvd Or, to load the driver as a module at boot, place the following lines in loader.conf(5): nvme_load="YES" nvd_load="YES"
DESCRIPTION The nvd driver exposes NVM Express (NVMe) namespaces as disks to the kernel disk storage API. It depends on the nvme(4) driver for notification of existing NVMe namespaces and sub‐ mission of NVM I/O commands. Device nodes from the nvd driver will have the format /dev/nvdX and are GEOM(4) disks which can be partitioned by geom(8). Note that device nodes from the nvme(4) driver are not GEOM(4) disks and cannot be partitioned.
SEE ALSO GEOM(4), nvme(4), geom(8), nvmecontrol(8), disk(9)
HISTORY The nvd driver first appeared in FreeBSD 9.2.
AUTHORS The nvd driver was developed by Intel and originally written by Jim Harris <>, with contributions from Joe Golio at EMC. This man page was written by Jim Harris <>.
