AI / GPU Data Center Interconnect Architecture
AI and GPU-driven infrastructure is pushing interconnect design further than traditional servers ever required — more bandwidth, higher power density, and tighter thermal margins, all at once. Here's how connector and interconnect choices shape modern AI data center architecture.

AI and GPU-accelerated computing has changed what "data center interconnect" means. Training and inference clusters move enormous volumes of data between GPUs, memory, and networking fabric simultaneously — often at 800G+ Ethernet speeds, with CXL-based memory expansion in the mix.
This puts real pressure on the physical interconnect layer: shrinking signal integrity margins, power delivery that's now a mechanical problem as much as an electrical one, and thermal density tight enough that connector placement affects cooling. The articles and tools below address these questions directly — signal loss tolerance, current derating, and thermal behavior in dense chassis.
Where This Shows Up
AI server architecture shows up most concretely in GPU accelerator platforms, where board-to-board and backplane connectors carry high-speed PCIe/CXL signaling and substantial power delivery in the same dense chassis. Co-packaged optics and copper are increasingly specified in next-generation AI networking fabric to reduce loss at 800G and beyond.
