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. You can learn more about these updates at NVMExpress.org.
