Emerging memory technologies have gotten a couple of big boosts over the past few years, one in the form of Intel’s Optane products, and the other from the migration of CMOS logic to nodes that NOR flash, and now SRAM, cannot practically support. Although these appear to be two very different spheres, a lot of the work that has been undertaken to support Intel’s Optane products (also known as 3D XPoint) will lead to improved use of persistent memories on processors of all kinds: “xPUs”.

Almost everyone understands that systems and data both have lifecycles that typically include a disposal phase (i.e., what you do when you do not need something anymore). Conceptually, data needs to be eliminated either on a system or entirely (everywhere stored) as part of this disposal. Failure to correctly eliminate certain data can result in costly data breach scenarios. Selecting the form of storage sanitization that is appropriate to the sensitivity of the data sensitivity and that also considers circular business models is something that many organizations are pursuing.

Azure Disks provide block storage for Azure Virtual Machines and are a core pillar of the Azure IaaS platform. In this talk, we will provide an overview of Direct Drive - Azure's next-generation block storage architecture. Direct Drive forms the foundation for a new family of Azure disk offerings, starting with Ultra Disk (Azure's highest performance disks). We will describe the challenges of providing durable, highly-available, high-performance disks at cloud scale as well as the software and hardware innovations that allow us to overcome these challenges.

NVMe-oF drives can support NVMe over ethernet, but how do you manage them? This presentation will show how Swordfish has developed a standard model for NVMe ethernet-attached drives, providing detailed profiles as guidance for implementations including required and recommended properties. This presentation will also cover the new features to support the latest version of the Native NVMe-oF™ Drive Specification.

Linux's ability to access files remotely via SMB3.1.1 continues to improve. Many new SMB3.1.1 features and optimizations have been implemented and with the new kernel server Linux (ksmbd) in mainline Linux there are now multiple Linux server options (Samba and ksmbd). Performance has improved with better use of leases in metadata caching, and dynamic reconfiguration of network interfaces and enhanced parallelization has improved multichannel performance.

Born in the '80s, the SMB family of protocols has been evolving for many years, with the latest version, SMB3.1.1, continuing to add features in order to support the largest breadth of clients (and an incredibly wide variety of servers).

Container Application deployments are growing exponentially, and so as the challenges with container data protection. Users are first worried to ensure the data backup for their deployments. Kubernetes provides data backup features through CSI. Is that sufficient? What are the new demands and challenges? What are the solutions to the challenges? How can we ensure container data backup beyond the CSI supported features? This session tries to answer these questions. Also, it discusses the current state of Kubernetes native data protection solutions.

This talk is going to give an overview of recent changes in the Samba fileserver and an outlook on the development roadmap. Recent development has been mainly focusing on security resulting in the release of Samba 4.15 last year. Looking forward there are many things the Samba fileserver development team has on its todo list and this presentation will give a first hand insight into the making of the next Samba versions.

The HDFS protocol supports POSIX.1e style ACLs. Supporting such ACLs in a multiprotocol environment means a translation method should be defined to translate between the NFSv3 mode bits, NFSv4 ACLs, Windows Style ACLs and the POSIX.1e ACLs. POSIX.1e ACLs differ in their structure and evaluation algorithm as compared to other ACLs that are currently supported in OneFS. The talk will detail the approach we took and also some of the surprising challenges related to multithreading.

In this presentation we will discuss why KV SSD is the ultimate storage solution, and why it will replace ZNS. We will explore how KV SSD solves many of the issues with flash management and the scaling of SSD devices in storage systems. KV SSD is a contrasting direction to Zone Namespaces and the migration of flash management to the Host. We feel KV SSD is a better direction, as the axiomatic optimal solution is to perform garbage collection at a single layer in any system, and that this garbage collection is optimal when it is as close to the flash as possible.
