Plugin: NVMe


This plugin adds support for NVMe storage hardware. Devices are enumerated from the Identify Controller data structure and can be updated with appropriate firmware file. Firmware is sent in 4kB chunks and activated on next reboot.

The device GUID is read from the vendor specific area and if not found then generated from the trimmed model string.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in an unspecified binary file format.

This plugin supports the following protocol ID:

  • org.nvmexpress

GUID Generation

These device use the NVMe DeviceInstanceId values, e.g.

  • NVME\VEN_1179&DEV_010F

The FRU globally unique identifier (FGUID) is also added from the CNS if set. Please refer to this document for more details on how to add support for FGUID.

Additionally, an extra instance IDs containing the version may be added.

  • NVME\VEN_1179&DEV_010F&VER_3B2QGXA7

Additionally, for NVMe drives with Dell vendor firmware two extra GUIDs are added:

  • STORAGE-DELL-${component-id}

and any optional GUID saved in the vendor extension block.

Update Behavior

The firmware is deployed when the device is in normal runtime mode, but it is only activated when the system is either restarted or in some cases shutdown.
