Cisco HCI-GPU-L40 | NVIDIA L40 GPU, 48GB GDDR6, 300W, PCIe Gen4 x16

Q: What workloads is the NVIDIA L40 GPU optimized for?
A: The NVIDIA L40 is optimized for AI inference, generative AI applications, virtual workstation deployments (with NVIDIA vWS software), 3D rendering, professional visualization, video processing, and graphics-intensive data center workloads. It excels at neural graphics, mixed-precision compute tasks, and ray tracing applications.

Q: Which Cisco server platforms support the HCI-GPU-L40?
A: This GPU is designed for Cisco UCS X-Series modular systems (particularly with the UCSX-440P PCIe Node in the X9508 chassis) and Cisco UCS C-Series rack servers. It requires PCIe Gen4 x16 slots and appropriate power delivery. Verify server compatibility and cooling requirements before deployment.

Q: What are the power and cooling requirements for the L40?
A: The NVIDIA L40 has a 300W TDP and uses passive cooling, meaning it relies on server airflow rather than onboard fans. Ensure your server has adequate forced-air cooling and a compatible power supply with PCIe power connectors. The card occupies two PCIe slots due to its dual-slot form factor.

Q: Can the L40 be used for virtual desktop infrastructure (VDI)?
A: Yes, when combined with NVIDIA RTX Virtual Workstation (vWS) software, the L40 can be virtualized to deliver high-performance GPU-accelerated workstation instances to remote users. With 48GB of memory, it supports multiple concurrent virtual workstation sessions for design, engineering, and compute-intensive applications.

Q: How does the L40 compare to the L40S?
A: The L40S is the successor model with enhanced performance. It features nearly double the TF32 and FP16 Tensor Core performance and increases maximum power from 300W to 350W. The standard L40 remains a cost-effective option for workloads that don't require the additional compute density of the L40S.
