FAQs

Q: What is the primary use case for the NVIDIA A16 GPU?
A: The A16 is purpose-built for high-density virtual desktop infrastructure (VDI) deployments. It excels at hosting graphics-rich virtual PCs and entry-level virtual workstations, supporting use cases from knowledge worker desktops to CAD applications. The quad-GPU design enables flexible resource allocation across mixed user profiles on a single card.

Q: How many virtual desktop users can the A16 support?
A: The A16 delivers double the user density compared to previous generation VDI GPUs. When combined with NVIDIA Virtual PC (vPC) or RTX Virtual Workstation (vWS) software, it can support numerous concurrent users depending on workload type, with optimized performance for knowledge workers and graphics-intensive applications.

Q: What server compatibility should I consider for the HX-GPU-A16?
A: The HX-GPU-A16 is designed for Cisco HyperFlex HX-Series nodes and UCS C-Series rack servers with PCIe Gen4 x16 slots. It requires a double-wide PCIe slot, appropriate server power supply capacity (minimum 250W for the GPU), and proper airflow for passive cooling. Check your specific HyperFlex or UCS model documentation for GPU slot compatibility and power requirements.

Q: Does the A16 require additional software licensing?
A: Yes, the A16 requires NVIDIA vGPU software licensing to enable virtual desktop and workstation functionality. Options include NVIDIA Virtual PC (vPC) for virtual desktops or NVIDIA RTX Virtual Workstation (vWS) for workstation-class applications. Licensing is typically per concurrent user or per GPU, depending on the deployment model.

Q: What are the key advantages of the Ampere architecture in the A16?
A: The NVIDIA Ampere architecture in the A16 provides second-generation RT Cores for ray tracing, third-generation Tensor Cores for AI-accelerated workloads, enhanced video encoding/decoding including AV1 support, and improved power efficiency. The quad-GPU design allows flexible partitioning and mixed workload support on a single card, maximizing infrastructure utilization.
