Astera Labs Inc. (NASDAQ: ALAB) announced the shipment of its Scorpio X-Series 320 Lane Smart Fabric Switch to hyperscale customers. The company described the product as the industry's largest open, memory-semantic fabric switch designed for AI scale-up clusters.

The switch supports configurations from 32 to 320 lanes and includes hardware-accelerated Hypercast and In-Network Compute engines. According to Astera Labs, these features can boost collective operations by up to 2x compared to traditional Ring AllReduce methods, based on the company's internal analysis.

The Scorpio family includes both X-Series and P-Series switches, spanning lane configurations from 32 to 320. The switches are designed to work with various accelerator types and system topologies for AI training and inference workloads.

"The Scorpio X-Series 320 Lane high-radix AI fabric switch replaces multiple legacy switches to enable larger scale-up cluster sizes in a single hop and reduce overall latency," said Jitendra Mohan, CEO of Astera Labs.

The switches feature memory-semantic connectivity that allows accelerators to access fabric resources through native load/store operations. The COSMOS software platform provides management capabilities including firmware updates, OpenBMC management, and real-time telemetry.

Astera Labs stated the switches are shipping into a merchant scale-up switch silicon market projected to reach $20 billion by 2030, with production ramp planned for the second half of 2026.

The company will demonstrate the Scorpio X-Series 320 Lane switch at Computex 2026 in Taipei from June 2-5, including PCIe 6 scale-up optics demonstrations.
