NVMe polishes its specs, brings virtualization to locally attached SSDs

The NVM Express (NVMe) specifications have been updated, gaining enhancements such as support for post-quantum cryptography, and SSD virtualization and live migration to better support virtualized environments. Announced by the NVM Express consortium, all 11 of the suite of NVMe specs have been updated with new features and engineering change notices. These represent the next step in the evolution of the standard, it says, which was created as a protocol to support storage devices connected to a system’s PCIe bus. Perhaps the most significant new capability is PCIe Exported NVM Subsystem Migration. This extends existing NVMe virtualization to locally-attached PCIe SSDs. It does this by abstracting the physical drives into host-defined...
