HPE S4A91C | 4-Way NVLink Bridge for H200 NVL GPUs, Quad GPU

This 4-way NVLink bridge connects four NVIDIA H200 NVL GPUs inside a compatible HPE server, providing direct GPU-to-GPU communication using 4th generation NVLink with 900GB/s bidirectional bandwidth. One bridge is used per quad of H200 NVL cards, making it well suited to scaling multi-GPU I/O for AI training, inference and HPC workloads. The 4-way (quad GPU) configuration differs from smaller bridge options by linking all four cards in a single interconnect.
