NVM Express Management Interface Specification

NVMe-MI™

The NVMe® Management Interface (NVMe-MI™) specification was created to define a command set and architecture for managing NVMe storage, making it possible to discover, monitor, configure, and update NVMe devices in multiple operating environments. NVMe-MI technology provides an industry standard for management of NVMe devices in-band (through an operating system) and out-of-band (usually through a BMC, or baseboard management controller).

The NVMe-MI 1.1 specification, released in April 2019, evolved to meet the growing management needs of the NVMe ecosystem. Anchor features include standardized NVMe enclosure management, the ability to access NVMe-MI technology functionality in-band and new management features for multiple NVMe subsystem solid-state drive (SSD) deployments.

As of August 2024, NVMe is a set of the following eleven specifications:

  • NVM Express® Base Specification, Revision 2.1
  • Command Set Specifications:
    • NVM Express® NVM Command Set Specification, Revision 1.1
    • NVM Express® NVMe Zoned Namespaces Command Set Specification, Revision 1.2
    • NVM Express® Key Value Command Set Specification, Revision 1.1
    • NVM Express® Subsystem Local Memory Command Set Specification, Revision 1.0
    • NVM Express® Computational Programs Command Set Specification, Revision 1.0
  • Transport Specifications:
    • NVM Express® NVMe over PCIe Transport Specification, Revision 1.1
    • NVM Express® RDMA Transport Specification, Revision 1.1
    • NVM Express® TCP Transport Specification, Revision 1.1
  • NVM Express® NVM Express Management Interface Specification, Revision 2.0
  • NVM Express® NVMe Boot Specification, Revision 1.1

The NVM Express® Base Specification, Revision 2.1 reorganizes sections to distinguish requirements on functionality common to PCIe® and Fabrics implementations, specific to PCIe implementations, and specific to Fabrics implementations.
