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 character of modern warfare is being reshaped by data. Sensors, autonomy, electronic warfare, and AI-driven decision systems are now decisive advantages, but only if compute power can be deployed fast enough and close enough to the fight. This reality sits at the center of recent guidance from the Trump administration and Secretary of War Pete Hegseth, who has repeatedly emphasized that “speed wins; speed dominates” and that advanced compute must move “from the data center to the battlefield.”
OSS specializes in taking the latest commercial GPU, FPGA, NIC, and NVMe technologies, the same acceleration platforms driving hyperscale data centers, and delivering them in rugged, deployable systems purpose-built for U.S. military platforms. At a moment when the Department of War is prioritizing speed, adaptability, and commercial technology insertion, OSS sits at the intersection of performance, ruggedization, and rapid deployment.
Maritime dominance has long been a foundation of U.S. national security and allied stability. Control of the seas enables freedom of navigation, power projection, deterrence, and protection of global trade routes. As the maritime battlespace becomes increasingly contested, congested, and data-driven, dominance is no longer defined solely by the number of ships or missiles, but by the ability to sense, decide, and act faster than adversaries. Rugged High Performance Edge Compute (HPeC) solutions have become a decisive enabler of this advantage.
At the same time, senior Department of War leadership—including directives from the Secretary of War—has made clear that maintaining superiority requires rapid integration of advanced commercial technology into military platforms at the speed of need. Traditional acquisition timelines measured in years are no longer compatible with the pace of technological change or modern threats. Rugged HPeC solutions from One Stop Systems (OSS) directly addresses this challenge.
Initial design and prototype order valued at approximately $1.2 million
Integration of OSS hardware into prime contractor system further validates OSS capabilities for next-generation 360-degree vision and sensor processing solutions
ESCONDIDO, Calif., Jan. 07, 2026 (GLOBE NEWSWIRE) -- One Stop Systems, Inc. (OSS or the Company) (Nasdaq: OSS), a leader in rugged Enterprise Class compute for artificial intelligence (AI), machine learning (ML) and sensor processing at the edge, today announced it has received an approximately $1.2 million pre-production order from a new U.S. defense prime contractor for the design, development, and delivery of ruggedized integrated compute and visualization systems for U.S. Army combat vehicles.
