The Linux SMB3.1.1 client continues to be one of the most active filesystems in Linux with many improvements added each year, enhancing its ability to securely, reliably and efficiently access remote data. This presentation will cover new features added to the Linux client, and new features you can expect to see over the coming year. Whether accessing data from the smallest devices or the largest (and even the cloud), getting at remote files matters.

As the one of the inventors of NVMe at Fusion-io, David has long been a thought leader in the SSD space. Large steps forward were made in data processing when NVMe was embedded in the server, bringing large quantities of high-performance data into direct contact with processing. However, data driven workload requirements have since changed, dramatically: 1) Larger quantities of data are being created, analyzed, and processed; 2) Demands for performance are not just growing, but, accelerating; and, 3) Most importantly, data needs to be more usable.

As the demand for cloud storage continues to grow, current centralized infrastructures are causing a detrimental impact on the environment. The cloud's carbon footprint has already surpassed that of the airline industry, but the recent surge in demand for AI is exacerbating the problem. Innovative storage solutions that reduce emissions without sacrificing performance and availability are needed now more than ever. In this session, we will delve into the technical aspects of how Storj is addressing this critical issue through an advanced distributed storage model.

Rapidly increasing data sizes, the high cost of data movement, and the advent of fast, NVMe-over-fabric based flash enclosures have led to the exploration of computation near flash for more efficient and economical storage solutions. Ordered key-value stores, commonly developed as software library code that runs inside application processes such as LevelDB and RocksDB, are one of many storage functions that can potentially benefit from offloaded processing.

DMTF has released SPDM version 1.3, with a number of enhancements to the protocol. These include: - Support for multiple keys - Event notification - Improvements in measurement handling - A hash-extended measurement mechanism - Endpoint identification - Even more support for extensibility by industry partners Status of libspdm, an open source implementation of the SPDM protocol on github. These changes enable new capabilities to be built on top of SPDM to enable a variety of solutions. Work on SPDM v1.4 is already underway.

TP4159 PCIe Infrastructure for Live Migration is an upcoming NVM Express® (NVMe) feature. The over-arching flow of Live Migration as viewed from an SSD will be discussed. Concerns for Live Migration state machine transitions, Virtual Memory (VM) addresses, log entry timings, and other implementation nuances will be highlighted. Attendees will obtain an understanding of both Source and Target SSD expected behaviors for Live Migration. In combination with the NVMe spec, attendees will be better prepared to implement an industry-compliant Live Migration feature for SSDs.

New technologies and platforms have laid waste to the assumptions of fixed-size, monolithic memory. Multiple layers of CXL-attached memory and persistent memory now provide a wide variety of types and speeds of memory available to developers of future systems. We will compare these various tiers of memories, whether inside the box or remotely attached. Next, we will examine how users and consumers of multi-tiered memory can make use of their varying characteristics, such as latency and persistence.

HPC architectures increasingly handle workloads where the working data set cannot be easily partitioned or is too large to fit into node local memory. We have defined a system architecture and a software stack to enable large data sets to be held in fabric-attached memory (FAM) that is accessible to all compute nodes across a Slingshot-connected HPC cluster, thus providing a new approach to handling large data sets.

CXL, an open industry standard interconnect, addresses the growing high-performance computational workloads to support heterogeneous processing and memory systems with applications in Artificial Intelligence, Machine Learning, Analytics, Cloud Infrastructure, Cloudification of the Network and Edge, communication systems, and High-Performance Computing by enabling coherency and memory semantics on top of PCI Express® (PCIe®) based I/O semantics to optimize performance in evolving usage models.

2023 has been an interesting and challenging year for storage security. The cyber threat landscape has witnessed large numbers of attacks impacting data and increased nation state activities directed at critical infrastructure. The regulatory landscape is undergoing change as well and potentially imposing requirements that necessitate adjustments to security capabilities, controls, and practices to reflect new realities. By the end of 2023 there will be significant changes to security standards and specifications relevant to storage.
