OCP Global Summit: Astera Labs Connectivity Portfolio Delivers Scale for Cloud and AI Infrastructure

Astera Labs, Inc. announced its entire product portfolio is fast-tracking cloud-scale workloads with unprecedented scaling capabilities.

The global cloud AI market size is estimated to grow at a CAGR of 39.6% from 2023 to 2030 to reach $647.61 billion ⁽¹⁾.

The company’s innovation in data center connectivity between accelerators, CPUs, GPUs, memory and networking is proving to be critical to support the growth of cloud infrastructure for AI and data-driven applications at scale.

“Accelerated computing platform deployments for large-scale AI workloads require purpose-built connectivity solutions to transport massive datasets,” said Thad Omura, SVP, business and corporate development. “Our hardware-optimized PCIe, CXL and Ethernet connectivity portfolio has been designed from the ground-up with a software-defined approach to enable customization and adaptation to ever-increasing scale requirements of accelerated compute applications.”

Unprecedented PCIe 5.0 reach for parallel processing of accelerators
The company’s Aries PCIe/CXL Smart DSP Retimers extend PCIe 5.0 reach for high-performance accelerators and are the most widely deployed retimers for cloud and AI infrastructure. The firm will also share how Aries PCIe Smart Cable Modules used in Active Electrical Cables will maximize reach for PCIe/CXL rack-to-rack connectivity. By extending reach by 3x, Aries enables ever-growing clusters of AI processors to be deployed for Generative AI training workloads interconnecting 1,000s of GPUs cost-effectively. With the growing demand and adoption of disaggregated architectures, Aries also offers extensibility for CXL memory pooling and fabrics at cloud scale.

Unprecedented flexibility for rack-scale Ethernet connectivity over copper

The company’s Taurus Ethernet Smart Cable modules extend 200/400/800GbE over copper cables which provides cost-effective scale-out connectivity for large, accelerated compute platforms. These modules offer flexibility for cable vendors to build the widest range of solutions from one-to-one, one-to-many, many-to-many, and half-active cables. At OCP Global Summit, the firm demonstrated for the 1st time its test platform for standard cable modules that simplify cable integration and provides a ‘testing at scale’ solution to meet the growing demand for Active Electrical Cables used in AI infrastructure.

Unprecedented memory bandwidth and capacity for volume data center servers

The company is a CXL innovator with its Leo Memory Connectivity Platform, enabling unprecedented DDR5 DRAM memory capacity and bandwidth in cloud servers. In partnership with Lenovo, the firm will showcase record memory capacity scaling by increasing the amount of addressable DRAM by an additional 133% in a dual processor x86 server platform with multiple Leo CXL memory controllers. Prior to Astera Labs’ CXL-attached memory solution, it was only possible to increase memory capacity with additional CPUs or servers with significant cost, power, and form factor drawbacks. Lenovo’s ThinkSystem SR675 V3 system integrates AMD EPYC CPUs and supports up to 8 Leo CXL memory controllers on a single server platform. The company is enabling the full potential of CXL for advanced accelerated computing platforms with significant performance, power and TCO advantages.

“With Astera Labs, we are excited to showcase dual-processor server configurations that are right-sized from a compute perspective to support volume data center applications with significant memory capacity,” said Pravin Patel, distinguished engineer, Lenovo Group Ltd. “Astera Labs’ CXL solutions enable the addition of high performance DDR5-5600 memory demanded by AI infrastructure.”

At OCP Global Summit, Astera Labs showcased its PCIe, CXL and Ethernet connectivity solutions that deliver scale for AI infrastructure and cloud connectivity.
