The Key Per IO (KPIO) project is a joint initiative between NVM Express® and the Trusted Computing Group (TCG) Storage Work Group to define a new KPIO Security Subsystem Class (SSC) under TCG Opal SSC for NVMe® class of Storage Devices. Self-Encrypting Drives (SED) perform continuous encryption on user accessible data based on contiguous LBA ranges per namespace. This is done at interface speeds using a small number of keys generated/held in persistent media by the storage device. KPIO will allow large number of encryption keys to be managed and securely downloaded into the NVM subsystem. Encryption of user data then occurs on a per command basis (each command may request to use a different key). This provides a finer granularity of data encryption that enables a granular encryption scheme in order to support use cases: Support of EU - GDPR Support of data erasure when data is spread over many disks, support of data erasure of data that is mixed with other data needing to be preserved (multitenancy), assigning an encryption key to a single sensitive file or host object. The presentation will introduce the architectural differences between traditional SEDs and the KPIO SSC, provide an overview of the proposed TCG KPIO SSC spec and the features in the NVMe commands to allow use of KPIO, and conclude by summarizing the current state of the standardization proposals in NVM Express and the TCG Storage WG. Learning Objectives: 1) Understand how encryption of data at rest protects that data today; 2) Understand how fine grain encryption (KPIO) will be used to protect data at rest in the future; 3) Understand possible use cases for KPIO (multi-tenant use of a common device, EU GDP use cases, others).

NVM Express® (NVMe®) has become synonymous with high-performance storage with widespread adoption in client, cloud, and enterprise applications. The NVMe 2.0 family of specifications, released in June 2021, allow for faster and simpler development of NVMe solutions to support increasingly diverse environments, now including Hard Disk Drives (HDDs). The extensibility of the specifications encourages the development of independent command sets like Zoned Namespaces (ZNS) and Key Value (KV) while enabling support for the various underlying transport protocols common to NVMe and NVMe over Fabrics (NVMe-oF™) technologies. This presentation provides an overview of the latest NVMe technologies, summarizes the NVMe standards roadmap, and describes new NVMe standardization initiatives. Learning Objectives: 1) Gain an overview of the latest NVMe technologies; 2) Summarize the NVMe standards roadmap; 3) Describe new NVMe standardization initiatives.

The NVMe 2.0 library of specifications have been broken out of multiple documents, including the NVMe Base specification, various Command Set specifications, various Transport specifications and the NVMe Management Interface specification. In this session, attendees will learn how the restructured NVMe 2.0 specifications enable the seamless deployment of flash-based solutions in many emerging market segments. This session will provide an overview and usages for several the new features in the NVMe 2.0 Specifications including ZNS, KV, Rotational Media and Endurance Group Management. Finally, the session will cover how these new features will benefit the cloud, enterprise and client market segments.

Since the first release of NVMe 1.0 in 2011, the NVMe family of specifications continue to expand to support current and future storage markets, increasing the amount of new features and functionality. With that natural, organic growth, however, comes additional complexity. In order to refocus on simplicity and ease-of-development, the NVM Express group has undertaken a massive effort to refactor the specification. The upcoming refactored specification - NVMe 2.0 - integrates the scalable and flexible NVMe over Fabrics architecture within the NVMe base specification, meeting the needs of platform designers, device vendors and developers. But how can developers optimally design their products using the new NVMe 2.0 specification? This session will provide attendees with the following insights: • An overview of the existing specification structure, its logic and limitations • Highlights on how developers use the current specification before refactoring • Information showing how the refactored specification enables companies to architect their products with better awareness of future areas of innovation • Details on how new features and functionalities will be included in the refactored specification • Descriptions of how developers can leverage the refactored NVMe 2.0 specification to simply and efficiently bring new products to market • Examination of the current projects and how to contribute Learning Objectives: 1) Overview of the current NVMe specification structure; 2) Introduction to NVMe 2.0: the refactored specification enables companies and developers to simply and efficiently bring new products to market; 3) The new features and functionalities that will be included in NVMe 2.0 and how to get involved in current projects.
