Cisco UCSX-GPU-A40-D | A40 Data Center GPU, 48GB GDDR6 ECC, PCIe Gen4 x16

Q: What workloads is the UCSX-GPU-A40-D optimized for?
A: The A40 GPU is optimized for AI inference and training, 3D rendering, ray tracing, virtual workstations, data science, simulation, CAD/CAE workflows, and high-performance computing tasks. It combines professional graphics capabilities with powerful compute and AI acceleration for multi-workload data center environments.

Q: Can I connect multiple A40 GPUs together?
A: Yes, the A40 supports NVLink technology. You can connect two A40 GPUs with an NVLink bridge to scale GPU memory from 48GB to 96GB and achieve increased GPU-to-GPU interconnect bandwidth of up to 112.5 GB/s for accelerated graphics and compute workloads.

Q: What server platforms is this GPU compatible with?
A: The UCSX-GPU-A40-D is designed for Cisco UCS X-Series modular systems including the UCSX-440P PCIe Node in UCS X9508 chassis. It requires PCIe Gen4 x16 slot (Gen3 compatible) and an 8-pin auxiliary power connection. Consult Cisco compatibility guides for specific server models.

Q: Are the display ports enabled by default on the A40?
A: No, the A40 is configured for virtualization by default with physical display connectors disabled. This supports SR-IOV and NVIDIA Virtual GPU software. The three DisplayPort 1.4a outputs can be enabled via the displaymodeselector management tool if physical displays are required.

Q: What is the difference between PCIe Gen4 and Gen3 performance?
A: PCIe Gen4 doubles the bandwidth of Gen3, improving data transfer speeds between the CPU and GPU for data-intensive workloads. For optimal performance, a Gen4 x16 connection is recommended, though the A40 is backward compatible with PCIe Gen3 x16 or Gen4 x8 connections for deployment flexibility.
