The Scorpio Smart Fabric Switch portfolio features two application-specific product lines with a multi-generational roadmap:

• Scorpio P-Series for GPU-to-CPU/NIC/SSD PCIe 6 connectivity – architected to support mixed traffic head-node connectivity across a diverse ecosystem of PCIe hosts and endpoints.
• Scorpio X-Series for back-end GPU clustering – architected to deliver the highest back-end GPU-to-GPU bandwidth with platform-specific customization.

Jitendra Mohan, Chief Executive Officer, Astera Labs, said, “Hyperscalers are deploying highly specialized AI platforms at an unprecedented pace, scale, and complexity. Our new Scorpio Smart Fabric Switch portfolio delivers maximum system utilization and uptime for two specific AI use cases – scale-out PCIe connectivity with Scorpio P-Series and back-end, scale-up GPU clustering with Scorpio X-Series. Scorpio offers energy efficient fabric solutions with predictable, secure, and high-performance data flows and extensive fleet management capabilities for accelerated AI infrastructure deployments at cloud-scale.”

Patrick Moorhead, Founder, Chief Executive Officer, and Chief Analyst, Moor Insights & Strategy, said, “Hyperscalers and AI platform providers developing systems for training and inferencing workloads have traditionally used PCIe switches that were initially designed for general purpose and storage applications. These switches can be complex, consume high power, and require longer system development cycles that make them challenging for AI platforms. With its introduction of the Scorpio Smart Fabric Switch portfolio, Astera Labs is focused on the industry’s need for a more performant, efficient fabric solution that’s purpose-built to meet the specific requirements of AI training and inference workloads in the cloud.”

Scorpio Smart Fabric Switches expand Astera Labs’ Intelligent Connectivity Platform and integrates with the COnnectivity System Management and Optimization Software (COSMOS) suite to deliver a smart, customizable connectivity backbone with unprecedented data center observability, enhanced security, and extensive fleet management capabilities. Scorpio enables unmatched insights into the state and health of accelerated computing platforms to ensure maximum uptime and availability.
