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 rugged edge computing landscape is becoming increasingly complex with new generations of technologies, such as the latest AI focused GPUs, releasing annually rather than every 2-3 years. Whether the end application is commercial or defense, rugged edge servers must not only deliver cutting-edge compute performance but also withstand extreme environmental conditions.
When the PCI-SIG formally added support for 675W add-in card devices in the PCI Express Card Electromechanical (CEM) specification in August 2023, NVIDIA’s most powerful CEM GPU, the NVIDIA H100 80GB had a maximum power consumption of 350W. While some devices were starting to push the limits of datacenter thermodynamics – high density systems of many 675W devices seemed like a distant reality. However, with power constraints uncapped and the need for higher performing GPUs skyrocketing, the industry quickly came out with devices taking full advantage of the new specification capability. NVIDIA quickly replaced the H100 80GB with the H100 NVL, increasing power density to 400W. While this small jump was manageable for existing installations, NVIDIA then dove all-in with the H200 NVL released in late 2024 at 600W. The rapid transition from 350W to 600W has put power and cooling technologies in the spotlight in a race to solve this next generation challenge.
