For the past three decades, PCI-SIG® has delivered a succession of industry-leading PCI Express® (PCIe®) specifications that remain ahead of the increasing demand for a high-bandwidth, low-latency interconnect for compute-intensive systems in storage applications and diverse market segments. In 2022, PCI-SIG announced the PCIe 7.0 specification is targeted for release to members in 2025.

Software-Enabled Flash™ (SEF) technology fundamentally redefines how flash memory is used for cloud and enterprise applications. Using highly-tuned, custom hardware and a host-based API and SDK, SEF technology empowers developers with control over data placement, latency outcomes and isolation. It is managed by a vendor-neutral Linux Foundation open source project that’s dedicated to enabling industry collaboration on this next evolution of storage. This session will introduce the SEF software and hardware stacks and describe how developers can access it.

Learn what is happening in NVMe to support Computational Storage devices. Computational Storage requires two new command sets: The Computational Programs Command Set and the Subsystem Local Memory Command Set. We will introduce you to how these two command sets work together, the details of each command set, and how they fit within the NVMe I/O Command Set architecture.

Computational Storage standards are under active development at both SNIA and NVMe. The CS TWG in SNIA continues to work on enhancements to the Architecture and Programming Model after the successful release of the 1.0 revision of the standard in August 2022. The CS TWG also continues to refine the CS API, which was released for public review in July 2022, to ensure alignment and compatibility with NVMe. Many of the same companies are engaged with the SNIA CS work and the NVMe CS work and strive to ensure compatibility and cohesion between the SNIA and NVMe CS standards.

To implement SMB2 unix extensions, smbd needs to implement ntfs reparse points to present symlinks, sockets and other special files to clients. This talk will present an overview of what reparse points are at their core and where Samba stands to implement them. Also, it will highlight the current status of the Linux kernel SMB client implementation regarding reparse points and special files over SMB2.

High-performance computing applications, web-scale storage systems, and modern enterprises increasingly have the need for a data architecture that will unify at the edge, and in data centers, and clouds. These organizations with massive-scale data requirements need the performance of a parallel file system coupled with a standards-based solution that will be easy to deploy on machines with diverse security and build environments.

Standards-Based Parallel Global File System - No Proprietary Clients

One of the goals of HPE’s Spaceborne Computer program is proving the value of edge computing. Spaceborne Computer-1 (SBC-1) was launched in August of 2017 with the latest available COTS (Commercial off the Shelf) hardware, including twenty solid state disks (SSDs) for storage. The disappointing durability of those SSDs will be covered; the Failure Analysis (FA) of them upon Return To Earth (RTE) will be presented and the mitigation done in Spaceborne Computer-2 will be detailed. HPE’s Spaceborne Computer-2 (SBC-2) launched in February of 2021 with over 6 TB of internal SSD storage.

With the increasing amount of network throughput, we'll reach a point where a data copies are too much for a single cpu core to handle. This talk gives an overview about how the io_uring infrastructure of the Linux kernel could be used in order to avoid copying data, as well as spreading the load between cpu cores. A prototype for this exists for quite some time and shows excellent results.

In this presentation, I will delve into the world of NVMe RAID and present a comprehensive analysis and comparison of various NVMe RAID engines. Through comparative testing and performance analysis using state-of-the-art performance analysis tools, I have identified bottlenecks in these engines when handling different workloads. During the presentation, I will provide valuable insights and comparisons, showcasing significant figures that highlight the performance differences among the tested NVMe RAID solutions.

In recent years, zoned storage has become pervasive across the storage software ecosystem, including file systems, cloud storage, and end-to-end application integrations. Zoned storage overcomes the drawbacks of write amplification by enabling the host to collaborate with the storage device when submitting writes. The ecosystem seamlessly integrates support for shingled magnetic drives (SMR HDDs), SSDs with Zoned Namespaces (ZNS SSDs), and UFS-enabled mobile devices through a single storage abstraction.
