Company to showcase next-generation PCIe 6.0 CopprLink™ cable adapters and new 4UPro-Max expansion accelerator for ultra-low latency, high-wattage AI workloads at Booth 2111

Latest innovation from OSS focused on supporting the next generation of commercial datacenters and edge computing markets

ESCONDIDO, Calif., Nov. 18, 2025 (GLOBE NEWSWIRE) -- One Stop Systems, Inc. (OSS or the Company) (Nasdaq: OSS), a leading provider of rugged, enterprise-class compute solutions for artificial intelligence (AI), machine learning (ML), and sensor processing at the edge, today announced a portfolio of next-generation PCI Express^® (PCIe^®) 6.0 CopprLink™ cable adapters and a new 4UPro-Max PCIe expansion accelerator. Together, these solutions are designed to support the latest generation of high-power AI/ML accelerators and data-intensive workloads in commercial datacenters, as well as applications at the edge. OSS will showcase the new best-in-class products at SuperComputing Conference 2025 (SC25), November 16–21 in St. Louis, Missouri, at Booth 2111.

Extending OSS Leadership in PCIe Expansion
“For over 20 years, OSS has been first to market with the latest generation PCIe large-scale expansion products, leading our customers into each new wave of high-performance compute and storage,” said Mike Knowles, President and CEO of OSS. “With our new PCIe 6.0 cable adapters and the 4UPro-Max, we are once again extending that leadership. These platforms combine high bandwidth, low latency and large-scale accelerator density to address the demands of evolving datacenter and rugged edge applications.”

Ultra-Low Latency PCIe 6.0 Connectivity with HIB6110
OSS’s HIB6110 PCIe 6.0 cable adapter, features an ultra-low-latency retimer-based design. HIB6110 transparently adapts any server’s x16 PCIe slot to an industry-standard x16 PCIe CopprLink external cable, enabling up to 256 GB/s of data throughput to high-speed external devices.

These devices include OSS’s extensive line of PCIe expansion accelerators as well as the next generation of Compute Express Link™ (CXL™) memory expansion and pooling systems, helping customers meet the bandwidth, latency and memory requirements of today’s large language models and other advanced AI workloads.

High-Bandwidth Switched Fabric with HIB6310
OSS’s HIB6310 PCIe 6.0 cable adapter, is a multi-port, switch-based design that delivers maximum performance and flexibility. HIB6310 provides up to 1,024 GB/s of PCIe switched-fabric bandwidth for sensor, HPC and AI data movement.
From a single x16 PCIe slot, HIB6310 offers both:

• 16 lanes of external PCIe 6.0 CopprLink cable connectivity, and
• 32 lanes of internal PCIe 6.0 connectivity.
  
  

This combination of internal and external lanes in a single adapter effectively “supercharges” Remote Direct Memory Access (RDMA) workflows. External sensor data can be routed directly to the latest GPU and FPGA accelerators and to NVMe storage devices inside OSS’s 2U and 3U Short Depth Servers (SDS), avoiding unnecessary hops through host system memory.

The HIB6310 further enhances RDMA performance through OSS proprietary multicast software and advanced SDS PCIe fabric topologies, enabling efficient fan-out of high-bandwidth data streams in complex systems.

4UPro-Max: Scaling to the Next Wave of High-Wattage Accelerators
In addition to PCIe 6.0 cable adapters, OSS is introducing the 4UPro-Max PCIe expansion system, designed to scale modern servers – including OSS’s 2U and 3U SDS platforms – with more high-power accelerators than previously possible.

Across the SC25 show floor, AI accelerators are pushing beyond 600 watts of power. 4UPro-Max extends the proven OSS 4UPro expansion family by delivering the connectivity, power and cooling needed to support up to eight PCIe 675W, dual-width accelerators in a single system. This new class of expansion enables customers to build denser, higher-performance systems for AI/ML training, inference, and other high-performance computing workloads.

Made in the USA, 4UPro-Max integrates the OSS Unified Baseboard Management Controller (U-BMC) with OSS proprietary software to monitor, manage and control critical system functions. The U-BMC includes an industry-standard Redfish^® API and offers advanced capabilities such as:

• Reconfiguring PCIe switch resources on the fly for agile, intelligent data infrastructure
• Integrating server and expansion management into a unified, single-pane-of-glass dashboard
  
  

These features allow customers to optimize performance, power and utilization across multiple OSS platforms with a consistent management experience.
