Modular Infrastructure

Requirements and Challenges​

• Support DC-MHS specifications for large server designs with modular disaggregated resources using connectors and cables with highly variable channel loss
• Running high speed PCIe over multiple connectors that increase insertion loss and crosstalk presents significant signal integrity and link stability challenges
• General purpose server nodes managing the activities of the other devices in the system 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 data center deployment without rigorous interoperability testing
