Soon you will be able to boot across a network with attached computers using NVME over Fabrics. This capability is often called Boot from SAN. Currently, successful storage networking technologies such as Fibre Channel and iSCSI have standardized solutions that allow attached computer systems to boot from OS images stored on attached storage notes. The lack of this capability in NVMe-oF architecture presents a barrier to adoption.
DNA lacks many key attributes found in other traditional storage media types including locality and addressability. The Rosetta Stone workgroup is aiming to solve the issue of enabling archive readers to understand key metadata about the archive and position them to be able to consume its contents. This session will provide an overview of where the Rosetta Stone workgroup is in the process of creating a recommended approach for this issue.
Gary Grider will kick off the talk with a brief background of the challenges currently faced in mass storage systems, and why it is so difficult for modern S3 based workloads to utilize them. Ben McClelland, who architected the system and did the bulk of the development, will introduce the Versity Gateway, an open-source high-performance object-to-file translation tool. He will explain that the Versity Gateway was written from scratch in Go, highlighting the benefits of this choice.
This talk presents the design and implementation of libvfn, a new open-source library for interacting with PCIe-based NVMe devices from user-space using VFIO. The core of the library is excessively low-level and aims to allow NVMe controller verification and testing teams to interact with devices at the register and queue level. While the library ships with a production ready NVMe driver with a high-level API, the library is designed to expose enough low-level VFIO functionality with which custom drivers can be implemented for any PCIe device as required by the application.
As large deployments become more common, our industry needs a standardized, multi-vendor solution to boot computer systems from OS images stored on NVMe® devices across a network. The newly published NVM Express® Boot Specification and ecosystem partnership with UEFI and ACPI enables this by leveraging the NVMe over Fabrics (NVMe-oF™) standard. This talk is a dive into the details of the new specification and the design of an open-source prototype for booting over NVMe/TCP transport using a UEFI implementation.
Deoxyribonucleic Acid (DNA) as a storage medium with high density and long-term preservation properties can satisfy the requirement of archival storage for rapidly increased digital volume. The read and write processes of DNA storage are error-prone. Images widely used in social media have the properties of fault tolerance which are well fitted to the DNA storage.
A new error correction code for DNA data storage is presented. The code takes advantage of the information about the noise in DNA data channel to clean up errors and erasure, that's why it is called DNA Noise Aware Errors Erasures Cleaner (DNAe2c). By modeling errors and erasures source with different state-of-the-art distributions and real data, we see an improvement of 10x over Reed Solomon codes requiring less than 20% overhead, making DNAe2c a promising candidate to accelerate DNA data storage adoption.
Synthetic DNA-based data storage has been on the rise as a candidate for Data Storage due to its longer shelf life and higher data density. This technology is expected to tackle the ever-increasing demand for cold storage and reduce energy consumption of data-centers to preserve information over long periods of time. In 2021, Lenovo and IPT joined the race towards DNA synthesis for data storage application. In regards to the traditional chemical method, the established “base-by-base” synthesis promises the highest information density on short length DNA strands.
There are several well-known advantages of using synthetic DNA for cold-data storage, such as higher density, reduced energy consumption, and durability compared with the standard storage mediums used for the same purpose. The enablement of this technology in the market involves the development of cost-effective DNA synthesizers that can write the data at an appropriate throughput speed and a CODEC able to handle data from different synthesis and sequencing technologies.
Security for NVMe over Fabrics is highly sought by customers and evolving at a fast pace. Experience with initial implementations uncovered a few shortcomings in the original design of certain NVMe/TCP security features that have resulted in recent security protocol changes. Furthermore, a lack of understanding on how configured single-system NVMe over Fabrics security policies interact led to the standardization in NVM Express of an interoperability framework. This session will explain these recent developments in NVMe-oF security and their importance to achieve a secure SAN.
