This week, Chris and Martin chat to Amber Huffman, Intel Fellow and President of NVM Express about the updates in NVMe 2.0. NVM Express (generally abbreviated to NVMe) is a storage protocol that was developed to overcome some of the shortcomings of traditional protocols when working with new high performance media such as NAND SSDs and Optane. The 2.0 release of the NVMe standard refactors the protocol design and also introduces new features, including Namespace Types, Zoned Namespaces, Key-Value data types, endurance group management and HDD support. Amber explains the rationale behind the restructuring and what specifically the new features will introduce. The conversation continues with insights into how NVMe 2.0 will be rolled out, and in particular the work being done with computational storage devices.
You can learn more about NVMe at nvmexpress.org or of course, review some of our older podcasts and blogs (linked below) where we introduce NVMe and discuss the impact of the technology on the enterprise.
