SNIA Developer Conference September 15-17, 2025 | Santa Clara, CA
On-Prem Object Storage: S3 Ecosystem and Its Role in Various Workloads
Abstract
Over the years, on-prem object storage has significantly evolved, with S3 and its API compatibility being key topics at S3 Plugfest. This presentation will explore the comprehensive S3 ecosystem, highlighting how various S3 features support diverse use cases, particularly in the context of rapidly advancing AI workloads. Additionally, we will delve into the role of S3 extensions in enhancing this ecosystem.

CXL Ecosystem Innovation Leveraging QEMU Based Emulation
As with any emerging technology, developing open-source software for CXL is challenging and emulation of features is a key path forward. In this talk, we will introduce the current major CXL features that QEMU can emulate and walk you through how to set up a Linux + QEMU CXL environment to enable testing and developing new CXL features. Some limitations exist, as with any platform, which we will discuss along with the latest developments in support for dynamic capacity devices (DCD) and switches. A key focus will be how to emulate and interact with these devices using a CXL Management Interface library (libcxlmi).
Lions and Tigers and MOE’s, Oh my! (or AI Acceleration and Tools)
In this talk, the author will explore the use of accelerators for the training and inference of models, and look at the proliferation of methods and models in the AI world.
From Standards to Practice: Implementing Effective QoS Control in NVMe SSDs
With promises to unlock new levels of shared performance and utilization efficiency in solid-state drives (SSDs), NVM Express® is developing Technical Proposal (TP), TP4176 - Quality of Service for PCIe Bandwidth and IOPS for a Controller. Defining a standard for QoS requires a deep understanding of its complexities as applied to an SSD. This presentation will delve into the potential QoS control modes, key parameters, and simplified control mechanisms, providing clarity on how to optimize SSD performance for emerging standards. Through varied deployment examples and usage scenarios, we will discuss strategies for setting intelligent QoS parameters on the host side, exploring where an SSD is expected to meet customer requirements and where hosts may need to manage expectations. Our goal is to spark a conversation for influencing discussions at NVM Express towards achieving consistent QoS across SSD vendors to provide the best products to our customer base.
Migration of a Virtual NVM Subsystem
The migration of a VM and the attached local NVM Express™ SSDs from one server to a different server does not provide a standard mechanism to guarantee that the information returned to the VM by Admin commands after the migration will be changed due to the different SSDs. This presentation provides an overview of how NVM Express™ is expanding on the Live Migration of an NVM Express™ physical controller and the NVMe-oF Exported NVM Subsystem feature, contained in the NVM Express Base Specification Revision 2.1, to provide a mechanism for the host to manage the returned information in Admin commands such that when a VM is migrated, that VM may not see changes to Admin command returned information.
SNIA Cloud Object Storage Test Tools (Open-Source Software Project)
During SNIA's Cloud Object Storage multi-vendor compatibility Plugfest held at SDC’24, it became apparent to the community during three days of testing that a lack of commonly accepted open source test tools is one of the more obvious pain points for the industry. All contributors test our implementations and all mature well accepted protocols conduct regularly scheduled Plugfests along with proactive development of open source test tools to get the job done. With this new effort, SNIA member companies intend to create and publish compatibility test software suites that help automate protocol compatibility testing of widely popular industry Cloud Object Storage APIs, wire-protocols and services.
These experts engaged in proprietary and/or open-source software development will discuss the real-world need for these test tools, and progress to date from the initial stages of SNIA member feedback and calls to action.
