Deliver high-performance, robust PCIe® link connectivity with optimized thermal efficiency for CPU root complex server boards that connect to GPU baseboards in AI servers.
Challenges:
- AI servers with multiple connectors between the AI head node to the GPU baseboard present PCIe signal integrity and link stability challenges
- Developing dense AI servers with high performance PCIe connectivity introduces routing, power delivery, and thermal design constraints
- Head nodes managing the activities of other servers in the cluster require devices with flexible software for diagnostics, customization, and Link, Fleet, and RAS management
- Dense PCIe links between multiple GPUs, CPU root complexes, PCIe switches, and other endpoints present risks in system design and data center deployment without rigorous interop testing
