DMTF’s Security Protocol and Data Model (SPDM) protocol is a widely used set of standards that enable secure communication and device authentication for platform-level security. This session will give an update on major developments by the SPDM Working Group, and where the group is going over the next year. In the past year, DMTF has released SPDM version 1.4, the first version to support CNSA 2.0 algorithms for post-quantum cryptography.
CXL enables disaggregated memory, both for composable capacity-on-demand and shared-memory. That is memory is not private to one server. Adding system-ram capacity should largely “just work”, but shared memory is more complex. The Fabric-Attached Memory File System (famfs) enables disaggregated shared memory to be used as memory-mappable files that map directly to the shared memory. Famfs is open source software which is on-track to be merged into the upstream Linux kernel in the coming months.
NTLM (NT LAN Manager) remains prevalent in storage environments, including SMB, where it’s often used to authenticate access to shared folders, NAS devices, and legacy systems that do not support Kerberos. However, NTLM carries significant security risks, such as susceptibility to relay, pass-the-hash, and brute-force attacks. Windows is now undergoing a transformation to eliminate NTLM, focusing on modernizing on-prem authentication by strengthening Kerberos and introducing new capabilities that close gaps where NTLM is traditionally required.
Linux users often ask: Why is my application slow? What caused it to crash? Was it a client-side issue—and if so, where? At SambaXP 2025, the Azure Files team introduced a new set of eBPF-based tools to help answer these questions by improving observability and debugging for Linux SMB client issues. We also shared a conceptual overview of the Always-On Diagnostics (AOD) project – a daemon that continuously monitors anomalies and automatically captures relevant logs when issues occur.
The bandwidth and capacity demand explosion of AI are forcing interconnects and storage to rapidly adapt and evolve. Pushing the bandwidth challenges the limits of the copper interconnect. The SNIA SFF Technical Working Group is proactively addressing the bandwidth needs through new development work on 448G channel modeling and PCIe 7.0 projects as well as studying mechanical aspects of the system design. In addition, there is a focus on how to meet the capacity and performance needs of storage for AI through a new EDSFF form factor.
Abstract With its introduction in 2011, the NVMe storage protocol has allowed CPUs to handle more data with less latency. This in turn has significantly improved the CPU's ability to manage parallel tasks with multiple queues while improving CPU utilization rates. More recently, the growing relevance of GPUs in AI training and inference has led to innovations that illustrate enabling NVMe storage access directly from GPUs. In this presentation we discuss some challenges with doing this efficiently.
