Description

The NVIDIA 4-way NVLink Bridge for H200 NVL is a high-bandwidth GPU interconnect bridge designed for HPE ProLiant DL380a Gen12 servers, enabling direct GPU-to-GPU communication across up to four NVIDIA H200 NVL PCIe GPUs. Delivering 1.8 TB/s bidirectional NVLink bandwidth and 564 GB of pooled HBM3e memory, it eliminates PCIe bottlenecks and is purpose-built for AI inferencing, large language model (LLM) hosting, HPC, and generative AI workloads — offering up to 1.7x faster LLM inference than the H100 NVL in a 2-way configuration.

By pooling memory across four GPUs into a single unified address space, this bridge enables workloads that exceed single-GPU memory limits, making it ideal for training and inference of frontier AI models. It is compatible with the NVIDIA AI Enterprise ecosystem and NVIDIA-Certified server platforms. Contact iptrading.com.au — your local source for enterprise-grade networking solutions.

Features

- Enables unified memory pooling across four NVIDIA H200 NVL GPUs — 564 GB HBM3e combined
- 1.8 TB/s bidirectional NVLink bandwidth for ultra-fast GPU-to-GPU data exchange
- Bypasses PCIe Gen5 bottlenecks — 7x faster GPU interconnect than PCIe
- Accelerates LLM inference up to 1.7x compared to H100 NVL
- Accelerates HPC workloads up to 1.3x compared to H100 NVL
- 3x more pooled memory versus a 2-way H100 NVL NVLink configuration
- Ideal for generative AI, LLM hosting, computer vision, and scientific discovery
- Compatible with NVIDIA AI Enterprise ecosystem and NVIDIA-Certified server platforms
- Supports parallel compute with near-direct GPU data exchange across all four GPUs

Warranty

Hewlett Packard Enterprise (HPE) offers a standard limited hardware warranty on its products, with coverage periods varying by product line. For instance, HPE ProLiant servers typically come with a 1 to 3-year limited warranty, while other products may have different durations.

FAQs

Q: What is the NVIDIA 4-way NVLink Bridge for H200 NVL used for?
A: It is used to interconnect up to four NVIDIA H200 NVL PCIe GPUs within a server, enabling high-bandwidth, low-latency GPU-to-GPU communication. It is ideal for large language model (LLM) inference, generative AI, HPC, and computer vision workloads that require large pooled GPU memory and fast data exchange between GPUs.

Q: Which server is this NVLink Bridge compatible with?
A: The NVIDIA 4-way NVLink Bridge for H200 NVL is compatible with the HPE ProLiant DL380a Gen12 server, supporting both SRF and GNR CPU configurations. It is designed specifically for use with NVIDIA H200 NVL PCIe GPUs in that platform.

Q: How much bandwidth does the 4-way NVLink Bridge provide?
A: The bridge provides up to 1.8 TB/s of total bidirectional NVLink bandwidth across all four connected GPUs, which is approximately 7x faster than PCIe Gen5 for GPU-to-GPU communication.

Q: How does this differ from a 2-way NVLink configuration?
A: The 4-way NVLink Bridge provides 3x more pooled HBM3e memory (564 GB) compared to a 2-way H100 NVL NVLink configuration, and significantly more bandwidth, making it suited for larger AI models and more memory-intensive workloads.

Q: Can I purchase the HPE S4A91C NVLink Bridge in Australia through IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller stocking HPE server accelerator options including the S4A91C. Contact our team for pricing, availability, and configuration advice tailored to your deployment requirements.

Q: Does this NVLink Bridge support NVIDIA AI Enterprise?
A: Yes. The NVIDIA 4-way NVLink Bridge for H200 NVL is compatible with NVIDIA-Certified systems and supports the NVIDIA AI Enterprise ecosystem, enabling enterprise-grade AI infrastructure deployments with full software stack support.
