Problem
Modern data centers struggle to provide the bandwidth, deterministic latency, and scalability required by AI training clusters and high‑performance computing (HPC) workloads. Existing Ethernet fabrics often introduce jitter and congestion, limiting the efficiency of distributed compute frameworks. As a result, organizations face higher operational costs and reduced performance for latency‑sensitive applications.
Solution
Virasemi delivers purpose‑built networking platforms that combine ultra‑low‑latency silicon, high‑density optical interconnects, and software‑defined control to meet the demands of AI and HPC environments. The solution integrates custom ASICs with 400 Gb/s Ethernet and RDMA‑capable interfaces, enabling deterministic packet delivery across large-scale clusters. A programmable data‑plane, exposed through open APIs, allows workload‑aware routing and congestion‑aware traffic shaping. End‑to‑end telemetry and AI‑driven performance analytics provide real‑time visibility and automated tuning of the fabric. The platform is compatible with major orchestration tools and can be deployed as a turnkey appliance or as a modular upgrade to existing infrastructure.
Target Audience
The primary customers are hyperscale cloud operators, enterprise AI research labs, and HPC facilities that require deterministic, high‑throughput networking for large‑scale distributed workloads. System integrators and data‑center OEMs seeking to differentiate their offerings with AI‑optimized fabric also constitute a key market segment.
