Paper Title: Refactoring NVMe creates Command Sets: NVMe Key Value and Zoned Namespaces

Paper Abstract: With the release of the NVMe 2.0 library, command sets have been separated out into individual standards. With this refactoring, NVM Express is enabling implementers to better utilize the command sets relevant to their specific use cases. As part of this refactoring, the NVM Express Technical Working Group released the NVM command set, NVMe Key Value (KV) command set, and NVMe Zoned Namespace (ZNS) command sets as separate specifications. Attendees will learn about these new specifications and how NVMe-KV and NVMe Zoned Namespaces offer crucial performance benefits such as reduced overprovisioning, increased transactions per second and improved control of I/O and data placement.
