A New Adapter for Zoned Namespace SSD

Submitted by Anonymous (not verified) on

Introduce the characteristics of ZNS SSDs and current Linux SW ecosystem for ZNS SSDs. Describe an adapter xZTL that enables the host to access ZNS SSDs easily. We adopt xZTL to Percona and benchmark by sysbench. The results show that xZTL improves TPS of ZNS SSD by 14% – 90% and reduces latency (p99) by 19% – 47% compared with conventional SSD of identical hardware.

Building an Object based STaaS solution with Poseidon Storage

Submitted by Anonymous (not verified) on

Samsung recently contributed Poseidon project, which is an OCP-based industry collaboration between component vendor (Samsung), system vendor(Inspur) and data center.

Poseidon is an open-source storage software and hardware platform for NVMe-oF based systems. It's an EDSFF based storage reference system, targeted for performance and density, suitable for cloud data center.

Today cloud service providers (CSP) are constantly challenged with large volumes of data and increasing demand from customers for cost effective storage.

Designing multi storage infrastructure in cloud deployment

Submitted by Anonymous (not verified) on

The major Cloud Providers such as VMWare, Microsoft and Google provide workload suites to deploy and manage container microservices and cloud storage through data models. Each of the vendor has their own storage model and format of storage(file, block). Meeting all of the requirements for a multi-cloud storage deployments with a generic cloud solution is challenging due to differences in the details of the models and behaviors across the Cloud Providers as well as the distributed nature of the configurations and deployments.

NVMe-oF™ Boot

Submitted by Anonymous (not verified) on

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.

Update on Standards for Consuming DNA Data Storage Archives

Submitted by Anonymous (not verified) on

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.

Versity Gateway, an Open Source High Performance Object to File Translation Tool

Submitted by Anonymous (not verified) on

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.

libvfn: A Low-level NVMe Application and VFIO Driver Framework

Submitted by Anonymous (not verified) on

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.

Booting over an NVMe/TCP Transport

Submitted by Anonymous (not verified) on

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.

Approximate DNA Storage with High Robustness and Density for Images

Submitted by Anonymous (not verified) on

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.

DNAe2c ECC for DNA Data Storage: 10x Improvement over RS Codes

Submitted by Anonymous (not verified) on

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.
