Interop Testing for Popular Endpoints

Overview of some enterprise PCIe® 4.0 endpoints featured in the Aries PCIe Smart Retimer Interop Report and use cases that require unique test setups for specific device functionalities.

Why We Test

 

Interoperability testing of PCIe retimers is critical for HPC and cloud applications. New compute-intensive workloads – such as Artificial Intelligence and Machine Learning – are becoming more mainstream in the enterprise data center, and require an array of high-performance, low-latency devices connected to the PCIe bus that adds to overall system complexity.

How We Test

 

Aries Smart Retimers are rigorously tested with all major root complexes and an ever-increasing range of PCIe endpoints to ensure seamless interoperation and low-risk designs. Each device is put through our exhaustive testing regime that uses the latest PCIe 4.0 systems from Intel and AMD to exercise the PCIe link to the target endpoint with a battery of tests over thousands of iterations.

Design with Confidence

The Cloud-Scale Interop Lab testing process establishes interoperability between Astera Labs Retimers and an exhaustive sampling of PCIe devices, allowing you to design with confidence, and reduce your development time and effort.
