By Mike Allison, Senior Director, Samsung At the inception of NVM Express® (NVMe®) technology, the NVM Command Set was the only mechanism for the NVMe specification to perform reads and writes. In today’s ecosystem, the majority of NVMe devices are using the NVM Command Set, and we will continue to see devices that support it. [...]
By Curtis Ballard, Distinguished Technologist, Hewlett Packard Enterprise The NVM Express® (NVMe®) over Remote Direct Memory Access (RDMA) transport was recently broken out into its own specification with the release of the NVMe 2.0 specifications. The NVMe over RDMA transport specification defines an interface for host software to communicate with NVM subsystems over a variety [...]
Sagi Grimberg, Co-Founder and CTO, LightBits Labs With the release of the NVM Express® over Fabrics (NVMe-oF™) 1.0 specification in 2016, the NVM Express organization made it possible for storage environments to extend the benefits of NVMe® technology across a networked fabric. In late 2018, NVM Express took this a step further by announcing added [...]
By John Geldman, Director of SSD Industry Standards, KIOXIA America Inc. From its inception, NVM Express® (NVMe®) technology has improved storage performance and complemented the PCI Express® (PCIe®) bus transport by providing a scalable, lower latency and more efficient solution than previous storage protocols. The NVMe over PCIe specification defines how NVMe architecture operates across [...]
By Karl Bonde Torp, Samsung NVM Express® (NVMe®) architecture has already overtaken SATA/SAS as the leading protocol for storage. As the adoption increases, so does the demand for new features to be added to the specifications. Since its inception, the specifications have expanded—adding the challenge of maintaining changes to the specification. For product developers implementing [...]
by Cameron Brett and Kerry Munson, NVM Express MWG Co-Chairs NVM Express is honored to receive the Flash Memory Summit (FMS) 2022 Most Innovative Memory Technology Award for the NVM Express® (NVMe®) 2.0 specifications. We are proud of this achievement and of the work from our member companies and contributors. As a result of a [...]
To say NVM Express is excited for the upcoming Flash Memory Summit (FMS) 2023 – taking place August 2-4 in Santa Clara, CA – would be a serious understatement. Flash Memory Summit (FMS) is returning to in-person after a two-year hiatus and we are looking forward to re-engaging with the wider storage community to highlight [...]
By Bill Martin, SSD I/O Standards, Samsung The NVM Express® Key Value (NVMe-KV) Command Set, ratified in June 2020, provides access to data on an NVMe® SSD namespace using a key, rather than a logical block address. Now that the NVMe-KV Command Set has been released as an official Command Set specification in the family [...]
By Austin Bolen, Distinguished Engineer, Server Storage at Dell EMC To evolve with the next phase of NVM Express® (NVMe®) technology, the NVMe Management Interface (NVMe-MI™) specification was modified to optimize NVMe SSD management and ensure interoperability with the other specifications. These changes have been released in the NVMe-MI 1.2 specification, which is available in [...]
By Sebastian Grandjean Perrenod Comtesse, NetApp High Performance Computing (HPC) and supercomputing have always involved complex system designs featuring highly specialized equipment at a massive scale. Years ago, some companies realized that IT infrastructure should be streamlined, and together they jointly developed a common reference architecture to simplify the overall design process. The sole purpose [...]
