The evolution of IT infrastructure spans several decades and is marked by significant advancements in computing technology, networking, storage, and management practices. Data Centers have historically relied on Converged or Hyper-Converged infrastructures when deploying their hardware, which proved limited in flexibility, efficiency, scalability, and support for the Artificial Intelligence / Machine Learning (AI/ML) modern workloads of today. Composable Disaggregated Infrastructure addresses these limitations by increasing resource utilization, and represents a paradigm shift in how IT infrastructure is designed. In this post, we’ll take an in-depth look at how this new technology is being deployed today, and why its revolutionizing the way organizations build and operate their IT environments.
In a Converged Infrastructure (CI), all the hardware resources are pre-configured and integrated into a single server, including processing, compute, storage, and networking tools. Multiple servers are racked together and connected over a common network backbone such as Ethernet, Fibre Channel, or InfiniBand. Converged Infrastructure is designed to simplify deployment by minimizing compatibility issues between systems, reduce complexity, and improve performance. For companies looking to scale, they simply deploy more pre-configured bundles of hardware and connect them to their network. While easier to manage, it often leads to scalability challenges, resulting in over-provisioning or underutilization of resources. Flexibility is also limited since deployments are often optimized for specific workloads, making it challenging to support changing requirements and introduce new technologies or components.
Hyper-Converged Infrastructure (HCI) addresses some of the limitations of a Converged Infrastructure by taking a software-based approach that integrates the processing, compute, storage, and networking resources into a single, software-defined, virtualized environment. Virtual servers are managed by a single hypervisor which provides simplified management, better scalability, and flexibility in modern data centers. Although a more adaptable IT Infrastructure approach, virtual machines (VMs) introduce performance overhead, latency, scaling granularity of a particular resource, and data locality concerns.
Enter Composable Disaggregated Infrastructure (CDI); a modern approach to IT Infrastructure that has transformed data center operations by providing a more agile, efficient, and flexible infrastructure foundation that can better support the evolving needs of modern businesses. Processing, compute, storage, and networking resources are disaggregated from their physical locations and put into a resource pool, which is managed by an API and dynamically allocated to a given workload while the other resources in the pool are being used elsewhere. For example, some workloads may require more GPUs for compute-heavy jobs or more storage for data recording purposes and those decisions can be made on the fly with software-defined intelligence which allows for optimal performance. CDI eliminates the need for workload-specific environments by offering a fluid set of resources that can be composed to meet the unique needs of any application. Resource utilization becomes optimized based on application requirements. Scalability becomes dynamic by being able to pick and choose resources in response to fluctuating workloads. Management is simplified since you don’t need to physically provision hardware. Downtime is also reduced because you can perform maintenance on unused resources without disrupting running applications.
Given all the advantages of composable infrastructure, many technology companies are competing to find an edge. Key differentiators between these technology companies often include bare metal servers, GPU/FGPA expansion accelerators, flash storage arrays, and networking interfaces, which are all interconnected by a physical top-of-rack PCI Express (PCIe) switch fabric and managed by their own special blend of software. PCIe switch fabrics are extremely high performance, supporting 256GB/s sustained throughput at Gen5, and provide much lower latency than other protocols such as Ethernet or InfiniBand. CDI companies take advantage of PCIe by leveraging expansion systems to support their GPU/FGPA/SSD/NIC resources and directly connect them to the top-of-rack PCIe switch. In doing so, all PCIe devices in the remote chassis appear to the host as directly connected PCIe peripherals on the PCIe switch fabric. A great example of the latest generation of PCIe 5.0 expansion system being leveraged by some of these technology companies today is the One Stop Systems' 4U Professional compute accelerator, which combines the power of the latest PCIe Gen5 add-in cards with an optimized, feature-rich, design for the most demanding HPC applications.
Overall, composable infrastructure represents a significant evolution in data center architecture, offering greater flexibility, efficiency, and scalability compared to traditional monolithic infrastructure models. By disaggregating resources into modular building blocks and providing a software-defined control plane for resource management, CDI enables organizations to adapt more quickly to changing business needs and drive innovation in their IT infrastructure.

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.
