Accelerate general purpose server deployments with high performance, robust PCIe® connectivity solutions in modular infrastructure based on industry standard specifications
Specification Background: The OCP DC-MHS (Data Center Modular Hardware System) specification targets server design and deployment with modular shared architectures. The goal is decreased costs and seamless hardware optionality through reuse, circular supply chains, and accelerated server design cycles.
Challenges:
- Requirement to support DC-MHS specs for large server designs with modular disaggregated resources using connectors and cables with highly variable channel loss.
- Running high-speed PCIe over multiple connectors increases insertion loss and crosstalk, creating signal integrity and link stability challenges.
- General purpose server nodes managing activities of the system’s devices require flexible software configuration for customization, Link, Fleet and RAS management, and diagnostics.
- Dense PCIe links between multiple CPU root complexes, PCIe switches, and other endpoints present risks in system design and deployment without rigorous interoperability testing.
