Cisco HX-GPU-A100-80 | A100 80GB HBM2e Graphics Card, 6912 CUDA, 300W

Q: What is Multi-Instance GPU (MIG) and how does it work on the A100?
A: MIG technology allows you to partition a single A100 GPU into up to seven isolated instances, each with dedicated memory, cache, and compute resources. This enables multiple workloads to run simultaneously with hardware-level isolation, improving GPU utilization and cost efficiency in multi-tenant or mixed workload environments.

Q: Which Cisco UCS servers are compatible with the HX-GPU-A100-80?
A: This GPU is compatible with Cisco HX240c and select UCS C-Series and X-Series servers that support PCIe Gen4 x16 expansion. It can be populated in Riser 1A slot 2, Riser 2A slot 5, or Riser 3C slot 7. Each compatible server can support up to three of these GPUs. The GPU requires a unique SBIOS ID registered with CIMC and UCSM for proper operation.

Q: What workloads benefit most from the 80GB memory configuration?
A: The 80GB HBM2e memory is ideal for training large language models, processing massive datasets in data analytics, running complex HPC simulations, and performing inference on memory-intensive AI models. The high memory capacity eliminates bottlenecks when working with models that exceed the 40GB available on smaller variants.

Q: Does this GPU support NVLink for multi-GPU configurations?
A: The HX-GPU-A100-80 PCIe variant supports NVLink Bridge for connecting two GPUs with 600 GB/s bidirectional bandwidth. For larger multi-GPU configurations beyond two units, GPUs communicate via PCIe Gen4 at 64 GB/s per GPU. The SXM form factor variants support full NVLink mesh topologies.

Q: What cooling requirements does this passive GPU have?
A: This is a passive cooled, 300W TDP GPU requiring robust chassis airflow for proper thermal management. It must be installed in a Cisco server with adequate front-to-back airflow and appropriate power supply capacity. The double-width form factor occupies two expansion slots.
