In this video, Jim Ison will do a quick walkthrough of the OSS 4U Pro Gen4 PCIe Expansion System. The 4U Pro is a rugged AI Transportable system that provides optimized, configurable PCIe Gen4 expansion for edge AI applications with up to 256 Gigabytes per second (GB/s) bi-directional host to expansion bandwidth and 768 GB/s aggregate system bandwidth.
This video will highlight some of the most important features of the 4U Pro Gen4 PCIe Expansion System and help you determine if this system is the right fit for your AI edge application.
As mentioned in the video, the 4U Pro supports up to 8 Gen4 double-wide GPUs, with four PCIe Gen4 x16 HBA/NIC slots for up to 256GB/s of sustained host to expansion data throughput. Alternatively, the 4U Pro can be configured to provide 16 single-width PCIe Gen4 x8 slots for scale out IO applications such FPGA data ingest or the latest NVMe storage add-in cards.
Additional features of the 4U Pro Gen4 PCIe Expansion System including dynamic fan speed control, IPMI based system monitoring and control, replaceable fan filters, and optional SmartNIC host configuration elevate the 4UP to the ideal expansion platform for the entire AI workflow. The 4U Pro combines the power of the latest PCIe Gen4 add-in cards with an optimized, feature-rich, and rugged design for the most demanding AI edge applications.
OSS has been a leading provider of PCIe technologies for many years – always one of the first to market with host interface boards and expansion backplanes for the latest PCIe generation. As Jim mentioned in the video, the 4U Pro is a Gen4 PCIe Expansion System, but will soon be available in PCIe Gen 5. The 4U Pro can help you bring the power of the datacenter to the rugged edge.

The term AI, or Artificial Intelligence, is everywhere nowadays and has quietly woven itself into the fabric of our daily lives. It powers the recommendations we see on streaming platforms, the navigation apps that guide us through traffic, and even the virtual assistants that answer our questions in seconds. From optimizing energy use in smart homes to predicting market shifts in finance, AI has become the invisible engine driving convenience, efficiency, and insight across industries.
In manufacturing, AI-driven robots collaborate with humans to streamline production. In agriculture, machine learning models monitor crops, forecast yields, and conserve resources. Retailers use predictive analytics to anticipate consumer needs before customers even express them. The reach of AI is no longer confined to futuristic labs, it’s in our phones, vehicles, and cities, constantly learning and adapting to serve us better.
OSS PCIe-based products deliver critical advantages for modern military sensor systems by enabling real-time data acquisition, processing, and transmission in rugged, mission-critical environments. These benefits stem from their ability to support high-bandwidth, low-latency interconnects, modular scalability, and environmental resilience, all of which are essential for today’s advanced military platforms.
Companies today are being asked to do more with data than ever before. Bigger AI models, faster insights, and workloads that don’t stay in one place, it’s a lot to keep up with. Traditional infrastructure just isn’t built for this kind of speed and flexibility.
The answer isn’t about throwing more hardware at the problem. It’s about building smarter, more agile infrastructure that adapts as demands change. And that’s where scale-out and increasingly, a blend of scale-out and scale-up come into play.
