Since the early stages of the 21st century, Peripheral Component Interconnect Express (PCIe) has established itself as the standard bus for workstation and server motherboards to interface with graphics cards, network cards, and many other categories of add-in cards. The throughput of full-length connections are heavily dependent on the generation of PCIe products being used, seen in the table below – and as the need for higher system performance in artificial intelligence and other computing applications intensifies, so does the demand for newer PCIe Gen5 products.
Leveraging years of experience in PCIe and PCBA design, One Stop Systems is a leader in the field of next-generation compute and storage scale-out. OSS offers a wide variety of expansion solutions ranging from individual board-level products to complete link kits compatible with any Windows or Linux-based servers. Through the use of OSS expansion products, a single PCIe slot can scale out to support up to 7 times as many slots, significantly increasing the compute density of the server network.
The Gen5 4U Professional Accelerator System (4UP) serves as the apex of OSS’ expansion products, with the capability of scaling out 8 double-wide add-in cards from a single host PCIe slot. In one use case, the system can support 8 NVIDIA H100s. An alternative system configuration can support up to 16 single-width PCIe Gen5 x8 slots for FPGA, NIC, or hybrid configurations. The 4UP’s rugged chassis and U-BMC system monitoring additionally ensure that the enclosure has the power and cooling to support the needs of high intensity computing for edge deployments.
Joining One Stop Systems’ roster of PCIe Gen5 products is the Gen5 3U Short Depth Server (SDS). First developed as a rugged server platform using PCIe Gen4 architecture, the 3U SDS has seen successful deployment as an all-in-one AI compute and storage solution in the autonomous long-haul trucking industry, among other applications. The new Gen5 SDS will maintain the same form factor as the original, while supporting multiple single and dual socket PCIe Gen5 motherboards. The Gen5 3U SDS will also incorporate the OSS Unified-BMC for advanced system monitoring and control of the entire host system, far surpassing the performance of the IPMI system management used in the Gen4 SDS. Additional features of the 3U SDS includes the capability of supporting two bulk-removable and hot-swap canisters of Gen5 NVMe storage and a variety of front/rear I/O customization options.
As the use cases and requirements of high-performance AI applications at the edge continue to evolve, the demand for robust compute servers will always be present. OSS is proud to support HPC at the edge through top-of-the-line products like the Gen5 3U SDS and 4UP and will continue to develop high quality systems as the industry moves towards PCIe Gen6 and beyond.

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.
