Astera Labs announced it is extending its collaboration with NVIDIA to support the NVLink Fusion ecosystem, introducing new scale-up connectivity solutions as part of its Intelligent Connectivity Platform. The move enables hyperscalers to integrate NVLink alongside PCIe, CXL, and Ethernet interconnects in data center environments that require high-performance, low-latency links for AI model training and inference.
Astera Labs’ expanded platform will help address the increasing performance demands of AI workloads with trillions of parameters. NVLink’s memory semantic-aware architecture is designed to synchronize hundreds of accelerators at rack scale, complementing Astera Labs’ existing offerings and management software, COSMOS, which provides system-level visibility and optimization. The collaboration builds on a multi-generational relationship between the two companies, with Astera Labs solutions already deployed across NVIDIA’s HGX, MGX, and NVL72 systems.
At NVIDIA GTC 2025, Astera Labs demonstrated end-to-end PCIe 6.0 interoperability between its Aries 6 Retimers, Scorpio P-Series Fabric Switches, and a NVIDIA Blackwell GPU—highlighting its role in enabling advanced connectivity across heterogeneous AI compute infrastructure. NVLink support will further expand the deployment options available to hyperscalers and OEMs building scale-up and scale-out AI systems.
