Astera Labs announced that their purpose-built PCIe 6 connectivity portfolio is now in production to accelerate the deployment of advanced AI platforms at scale.
Astera Labs’ expanding PCIe 6 portfolio now includes gearbox connectivity solutions in addition to fabric switches, retimers, and active cable modules, providing a comprehensive connectivity platform that delivers unparalleled performance, utilization, and scalability for next-generation AI and general-compute systems.
Along with Astera Labs’ demonstrated PCIe 6 connectivity over optical media, the portfolio will offer even more AI rack-scale distance options. The requirement for increased computing, memory, networking, and storage data throughput is driving the switch to PCIe 6, ensuring modern AI accelerators and GPUs run at top efficiency.
Industry-Leading PCIe 6 Connectivity Portfolio
PCIe 6 technology is crucial for providing the high bandwidth, low latency interconnects required to maximize AI task scaling by fully using the latest GPUs.
Astera Labs’ extensive PCIe 6 portfolio of purpose-built silicon, modules, and boards is ramping up production across several, diversified AI platforms, ready for deployment in real-world systems with major hyperscale customers.
- NEW Aries 6 PCIe Smart Gearbox – the industry’s first purpose-built PCIe gearbox solution that intelligently bridges the performance gap between the latest PCIe 6 devices and existing PCIe 5 ecosystem. Aries 6 Gearbox solves the challenge of degraded-performance in mixed-generation systems, ensuring full utilization of high-speed lanes and accelerating the deployment of next-generation AI platforms while optimizing rack-scale TCO.
- Scorpio P-Series Smart Fabric Switches – the industry’s first PCIe 6 fabric switches architected for mixed traffic AI head node connectivity deliver predictable, high-performance data flows between GPUs, CPUs, NICs, and SSDs. Scorpio P-Series enables high-bandwidth, low-latency peer-to-peer GPU data ingest while ensuring seamless interoperability across a diverse ecosystem of PCIe hosts and endpoints.
- Aries 6 PCIe/CXL Smart DSP Retimers – as the gold standard for PCIe retimers, these devices solve high-speed PCIe 6.x/CXL® 3.x signal integrity challenges in AI and general-compute servers with reliable 3x reach extension. Aries 6 Retimers deliver high-performance, low power connectivity while providing a smart connectivity backbone that is reliable, interoperable, and scalable for diverse hyperscale deployments.
- Aries 6 PCIe/CXL Smart Cable Modules (Aries 6 SCMs) – extend PCIe 6.x/CXL 3.x signal reach up to 7 meters for GPU clustering across dense AI racks over copper-based Active Electrical Cables (AECs). Built on the proven track record of widely deployed and field-tested Aries Retimers, Aries 6 SCMs support multiple form factors and configurations to accommodate diverse AI system topologies.
- PCIe 6 over Optics Technology – enables PCIe 6 optical connectivity for GPU and AI accelerator scale-up clustering across longer distances to enhancing rack-scale data center flexibility. Astera Labs’ optical DSP technology easily integrates into AOC modules and optical transceivers, supporting future optical connectivity standards through software-defined configurability.
The expanded PCIe 6 portfolio 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. COSMOS enables unmatched insights into the state and health of accelerated computing platforms to ensure maximum uptime and availability.
Astera Labs’ PCIe-based solutions are rigorously tested in the company’s Cloud-Scale Interop Lab and in customer platforms with leading PCIe hosts and endpoints across multiple PCIe generations and topologies. This essential interoperability and performance testing enables customers to design with confidence, minimize interoperation risk, and reduce overall development time and costs.
