Cisco HCI-GPU-A16 | NVIDIA A16 64GB GPU, Quad-GPU VDI, Passive Cooling

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. Its quad-GPU design enables up to 64 concurrent knowledge worker virtual desktop sessions per card, making it ideal for organizations rolling out GPU-accelerated remote work environments for Office 365, web browsing, video conferencing, and light CAD workloads.

Q: How does the quad-GPU architecture work?
A: The A16 features four independent 16GB Ampere GPUs on a single dual-slot card, connected via an on-board PCIe switch. Each GPU operates independently with its own compute and memory stack, allowing flexible allocation for mixed user profiles. IT can provision virtual PCs, entry-level virtual workstations, and even virtualized compute on the same board.

Q: What are the cooling requirements for this GPU?
A: The A16 uses passive cooling and requires adequate server airflow for proper thermal management. It is designed for data center rack servers with front-to-back airflow. Cisco and other OEMs typically require specific air ducts or baffles when installing dual-width GPUs to ensure proper cooling.

Q: Is the A16 suitable for AI training or machine learning workloads?
A: The A16 is optimized for VDI user density, not AI training. While it includes Tensor Cores for AI inference acceleration, its 16GB per-GPU memory and GA107 architecture make it better suited for virtual desktops, graphics virtualization, and entry-level CAD. For dedicated AI workloads, consider compute-optimized GPUs like the A100 or H100.

Q: What server compatibility should I verify before ordering?
A: Verify that your server supports PCIe 4.0 x16 slots, dual-slot GPU form factor, 250W power delivery via 8-pin EPS connector, and passive GPU cooling with appropriate airflow. Cisco UCS C-series and HCI platforms list compatible configurations in their specification sheets. Check slot compatibility and ensure NVIDIA vGPU software licensing is in place for VDI functionality.
