Cisco UCSC-GPU-L40S | L40S GPU, 48GB GDDR6, 350W, 2-Slot FHFL, PCIe Gen4

Q: What workloads is the UCSC-GPU-L40S optimized for?
A: The L40S is designed for generative AI, large language model (LLM) inference and training, 3D rendering, real-time ray tracing, video encoding and decoding, virtual desktop infrastructure (VDI), and NVIDIA Omniverse applications. Its balanced AI compute and graphics capabilities make it ideal for mixed-workload data center deployments.

Q: What Cisco UCS servers are compatible with this GPU?
A: The UCSC-GPU-L40S is compatible with select Cisco UCS C-Series rack servers such as the C240 M8 and UCS X-Series PCIe nodes like the X440p. It requires a dual-slot full-height full-length (FHFL) PCIe slot and 350W power delivery. Check your server's configuration guide for GPU compatibility and required accessories like air ducts and power cables.

Q: Does the L40S support GPU virtualization?
A: Yes, the L40S supports NVIDIA vGPU software, enabling multiple virtual machines to share GPU resources for virtual desktop infrastructure (VDI) and virtual workstation deployments. This allows efficient GPU utilization across virtualized environments for both AI and graphics workloads.

Q: How does the L40S compare to the previous generation L40 and A40 GPUs?
A: The L40S delivers up to 2x faster AI inference performance compared to the original L40 and up to 5x higher inference performance than the NVIDIA A40. It increases maximum power from 300W (L40) to 350W and nearly doubles TF32 Tensor Core performance, making it significantly more capable for modern AI and rendering workloads.

Q: What display connectivity does the L40S provide?
A: The L40S includes 4x DisplayPort 1.4a outputs, allowing direct monitor connectivity for visualization workloads, real-time rendering, and professional graphics applications. This makes it suitable for both headless data center compute tasks and interactive visual computing scenarios.
