# nvme(4)

Non-Volatile Memory Host Controller Interface

## NAME

**nvme** – Non-Volatile Memory Host Controller Interface

## SYNOPSIS

**nvme\* at pci?** **nvme\* at aplns?                # arm64**

## DESCRIPTION

The **nvme** driver provides support for NVMe, or NVM Express, storage controllers conforming to the Non-Volatile Memory Host Controller Interface specification.

Although the NVMe specification provides its own command set, the **nvme** driver provides access to the storage via a SCSI translation layer.

Sensor values are made available through the *hw.sensors* [sysctl(8)](/sysctl/8.md) interface.

## SEE ALSO

## HISTORY

The **nvme** driver first appeared in OpenBSD 6.0.

## AUTHORS

The **nvme** driver was written by David Gwynne ⟨*dlg@openbsd.org*⟩.
