Executive Summary

The Astera Labs Scorpio 320-Lane is a high-radix, memory-semantic interconnect designed to support large-scale AI clusters with reduced latency and improved efficiency. This smart fabric switch is part of Astera Labs' Scorpio X-Series and P-Series families, which support high lane counts and advanced hardware-accelerated features for AI network scaling. The Scorpio 320-Lane switch is designed to provide minimal latency for large-scale clusters and is now shipping to leading hyperscalers.

The Scorpio 320-Lane switch is a significant upgrade over previous Scorpio switches, offering 320 PCIe lanes, which is a large switch in the current market. This allows system designers to connect more devices with fewer switch chips and fewer hops, making it an attractive option for large-scale AI clusters.

Astera Labs' Scorpio X-Series 320-Lane Smart Fabric Switch embeds Hypercast and In-Network Compute engines to improve token economics and accelerator utilization in large-scale AI clusters. The switch is designed to rethink the way switches interact with the chips they're linked to, providing a more efficient and scalable solution for AI workloads.

The Scorpio 320-Lane switch is a key component in Astera Labs' strategy to provide a complete rack-scale connectivity portfolio for AI scale-up systems. The company will showcase the Scorpio X-Series 320 Lane and its complete rack-scale connectivity portfolio at Computex 2026.
