FAQs

Q: What workloads is the A40 GPU optimized for?
A: The A40 is designed for data center visual computing workloads including AI inference and training, 3D rendering, ray tracing, virtual workstations (VDI), simulation, CAD/CAE applications, and high-performance computing tasks requiring large memory capacity.

Q: Does this GPU have video display outputs?
A: The Cisco HCI-GPU-A40 is configured as a headless data center card with no external display connectors. It is intended for server integration and virtualization deployments rather than direct display connection.

Q: Can two A40 GPUs be linked together?
A: Yes, two A40 GPUs can be connected via NVLink bridge to scale memory capacity from 48GB to 96GB and increase GPU-to-GPU interconnect bandwidth, enabling unified memory for larger datasets and improved performance in supported applications.

Q: What are the cooling requirements for this GPU?
A: The A40 uses passive cooling and requires adequate chassis airflow to dissipate the 300W thermal load. It is designed for rack-mount servers with optimized front-to-back or side-to-side airflow configurations.

Q: Is this GPU compatible with NVIDIA vGPU software?
A: Yes, the A40 supports NVIDIA vGPU software including vPC, vApps, RTX Virtual Workstation, and Virtual Compute Server, enabling virtualized GPU resources for multiple concurrent users in VDI and cloud environments.
