NAME

nvme - the NVMe storage command line interface utility (nvme-cli)

SYNOPSIS

built-in plugin:

nvme <command> <device> [<args>]

extension plugins:

nvme <plugin> <command> <device> [<args>]

DESCRIPTION

NVM-Express is a fast, scalable host controller interface designed to address the needs for not only PCI Express based solid state drives, but also NVMe-oF(over fabrics).

This nvme program is a user space utility to provide standards compliant tooling for NVM-Express drives. It was made specifically for Linux as it relies on the IOCTLs defined by the mainline kernel driver.

NVME COMMANDS

The utility has sub-commands for all admin and io commands defined in the specification and for displaying controller registers. There is also an option to submit completely arbitrary commands. For a list of commands available, run "nvme help".
