NVMe 2.1 Specifications Published With New Capabilities
At the Flash Memory Summit 2024 this week, NVM Express published the NVMe 2.1 specifications, which hope to enhance storage unification across AI, cloud, client, and enterprise. Phoronix's Michael Larabel writes: New NVMe capabilities with the revised specifications include:
- Enabling live migration of PCIe NVMe controllers between NVM subsystems.
- New host-directed data placement for SSDs that simplifies ecosystem integration and is backwards compatible with previous NVMe specifications.
- Support for offloading some host processing to NVMe storage devices.
- A network boot mechanism for NVMe over Fabrics (NVMe-oF).
- Support for NVMe over Fabrics zoning.
- Ability to provide host management of encryption keys and highly granular encryption with Key Per I/O.
- Security enhancements such as support for TLS 1.3, a centralized authentication verification entity for DH-HMAC-CHAP, and post sanitization media verification.
- Management enhancements including support for high availability out-of-band management, management over I3C, out-of-band management asynchronous events and dynamic creation of exported NVM subsystems from underlying NVM subsystem physical resources.
