Now Shipping to Leading Hyperscalers, Scorpio Smart Fabric Switch Family Delivers Breakthrough Accelerator Utilization Through Memory-Semantic Based Open and Platform-Specific Protocols
News Highlights:
- Largest open, memory-semantic fabric switch: The Scorpio™ X-Series 320 Lane AI fabric switch, shipping today, supports increased scale-up cluster sizes with low latency
- Intelligent AI fabric with In-Network Compute to maximize token economics: Hardware-accelerated Hypercast™ and In-Network Compute engines boost collective operations by up to 2x [1], to improve time to first token and tokens-per-watt performance
- Broadest family of PCIe 6 fabric switches: From 32 to 320 lanes, the newly-expanded Scorpio P-Series enables diverse accelerator optionality and system topologies
SAN JOSE, Calif., May 05, 2026 (GLOBE NEWSWIRE) -- Astera Labs, Inc. (Nasdaq: ALAB), a leader in semiconductor-based connectivity solutions for rack-scale AI infrastructure, today announced the Scorpio™ X-Series 320 Lane Smart Fabric Switch, the industry's largest open, memory-semantic fabric switch engineered to improve token economics and support large scale-up clusters with minimal latency. Astera Labs also announced an expanded Scorpio P-Series PCIe fabric switch family—now spanning 32 to 320 lane configurations—designed to give data center architects at AI labs, hyperscalers, and neo-clouds the flexibility to rapidly scale compute capacity across diverse accelerators for training and serving frontier AI models.
As AI deployments move into large-scale production and achieve operational efficiency, infrastructure teams face a new set of constraints: multi-trillion-parameter models, agentic workflows, and multi-step reasoning distributed across heterogenous compute infrastructure. The industry needs connectivity solutions purpose-built for these workloads—higher radix to simplify topologies, intelligent fabric capabilities to reduce communication overhead, open and platform-specific optimizations, and datacenter-grade diagnostics to maintain uptime when a single fault can cost millions of dollars in idle compute. Scorpio Smart Fabric Switches are purpose-built to address each of these constraints and meet the demands of production AI at scale.
Scorpio's software-defined architecture is designed to integrate seamlessly with leading merchant and custom silicon, enabling AI labs and hyperscalers to integrate and deploy new accelerator platforms for both training and inference. Its memory-semantic connectivity enables accelerators to access fabric resources through native load/store operations, eliminating software overhead and improving fabric efficiency at scale. Scorpio X-Series delivers simplified high-radix scale-up topologies, cutting hops and reducing end-to-end latency across the cluster. Newly introduced Hypercast™ and In-Network Compute engines accelerate collective operations by up to 2x to maximize GPU utilization and tokens-per-watt performance. Rounding out the family, the Scorpio P-Series complements the X-Series in front-end network and AI compute system deployments, to deliver resiliency, dynamic configurability, and broad interoperability.
COSMOS™ software unifies the platform with purpose-built resiliency and serviceability, delivering non-disruptive firmware updates, OpenBMC management, and real-time telemetry. Hypercast and In-Network Compute are configured through COSMOS, extending its capabilities to now include platform performance optimizations. These capabilities are designed to maximize uptime, accelerator utilization, and ensure operational reliability for continuous production workloads while accelerating rack validation and compressing time-to-deployment. COSMOS extends across Astera Labs' complete rack-scale portfolio of fabric switches, copper connectivity, and optical solutions, enabling composable AI infrastructure from a single unified management software stack.
"The frontier models driving today's most demanding AI applications require connectivity infrastructure that keeps pace with the accelerators powering them," said Jitendra Mohan, CEO of Astera Labs. "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. Hardware-accelerated Hypercast and In-Network Compute engines further boost collective operations by up to 2x to improve tokens-per-watt performance. Together, with Astera Labs' complete rack-scale connectivity portfolio, including the expanded 32 to 320 lane Scorpio P-Series PCIe fabric switches, give infrastructure teams a platform to build and scale AI entirely on their terms."
The Scorpio X-Series 320 Lane Smart Fabric Switch is shipping into a merchant scale-up switch silicon market projected to reach
Patrick Moorhead, Founder, CEO and Chief Analyst, Moor Insights & Strategy, said:
"As AI moves into production, the bottleneck is shifting off the GPU and into the fabric that connects these systems. The pace of accelerator refresh is exposing how rigid many of these interconnects are, especially the closed ones, where every upgrade turns into a forklift decision. With the broadened Scorpio family, Astera Labs is pushing toward a more open, high-radix approach that reflects how AI clusters are being built and run."
Dylan Patel, Founder, CEO, SemiAnalysis, said:
"At the scale AI labs are operating, interconnect is where GPU utilization goes to die. Scaling effective interconnect bandwidth is built upon two key pillars: Implementing efficient in-network compute of collective operations and reducing latency by collapsing multi-hop topologies into single-hop topologies. AI labs that control their fabric architecture, closely co-design networking solutions with compute ASICs, and thus enable step-change improvements in scale-up networking will have a structural cost and performance advantage. The Scorpio Smart Fabric Switch Family is the first open-standard platform that credibly addresses both of these pillars."
See Scorpio at Computex 2026
Astera Labs will showcase the Scorpio X-Series 320 Lane and its complete rack-scale connectivity portfolio at Computex 2026 (Taipei, June 2-5), including industry-first PCIe 6 scale-up optics demonstrations leveraging COSMOS for end-to-end link management.
