# InfiniBand Cable Validation

Validates InfiniBand network cabling for high-performance computing and GPU interconnect infrastructure. This workflow checks the *connectivity* of hosts against intended cabling defined in Nautobot. The workflow **does not verify traffic flows**, but does verify that each device has the expected neighbors.

This workflow is experimental and has not completed QA. Use it only in test or pilot environments.
