Cisco CAI-GPU-H200-NVL | H200 NVL Graphics Card, 141GB HBM3e, 600W, PCIe 5.0

Q: What is the difference between H200 NVL and H200 SXM?
A: The H200 NVL is a PCIe add-in card with 600W TDP designed for air-cooled enterprise servers, while the H200 SXM is a 700W module requiring liquid cooling and specialized HGX baseboard systems. Both share the same 141GB HBM3e memory and GH100 silicon, but the SXM variant offers slightly higher peak compute performance due to higher power delivery.

Q: Can the H200 NVL be used in standard PCIe servers?
A: Yes, the H200 NVL is designed as a drop-in PCIe 5.0 x16 card compatible with standard enterprise rack servers. However, the passive cooling design requires adequate server airflow and chassis design to handle the 600W thermal load.

Q: What is NVLink and how does it benefit multi-GPU configurations?
A: NVLink is NVIDIA's high-speed GPU-to-GPU interconnect providing 900GB/s bandwidth per GPU, which is 7x faster than PCIe 5.0. The H200 NVL supports 2-way or 4-way NVLink bridges, enabling efficient data sharing for distributed AI training and large-scale inference workloads across multiple GPUs.

Q: What workloads benefit most from the H200 NVL's 141GB memory?
A: The H200 NVL excels at memory-intensive workloads including large language model inference and fine-tuning, generative AI applications with extended context windows, high-parameter-count model training, scientific simulations, and HPC applications requiring large working datasets.

Q: Does the H200 NVL support Multi-Instance GPU?
A: Yes, the H200 NVL supports up to 7 MIG instances, allowing a single GPU to be partitioned into multiple isolated instances with dedicated compute, memory, and bandwidth resources. This enables secure multi-tenancy and maximizes GPU utilization across diverse workloads.
