NVMe Polishes Its Specs, Brings Virtualization to Locally Attached SSDs

slashdot.org · 6dShare

The latest NVMe specifications add SSD-level virtualization that can simplify live VM migration by preserving storage identities across servers. The updates also introduce support for post-quantum cryptography, controller-based rate limiting, voltage monitoring, and factory-reset capabilities. The Register reports: 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 virtualized NVM subsystems, to allow for virtual machine (VM) mobility without storage reconfiguration. When a VM moves from one server to another, i
