Cisco UCSX-GPU-L40S | NVIDIA L40S 48GB GDDR6 Graphics Card, 350W, PCIe Gen4

Q: What servers is the UCSX-GPU-L40S compatible with?
A: This GPU is designed for Cisco UCS X-Series Modular Systems, specifically the X410c M7 Compute Node with X440p PCIe expansion nodes. It requires appropriate riser cards and power cables that are included with the PCIe node.

Q: What workloads is the L40S GPU optimized for?
A: The L40S excels at generative AI inference, large language model fine-tuning and deployment, 3D rendering and visualization, video transcoding and streaming, virtual workstation applications, and mixed AI-graphics workloads. It's particularly effective for models up to 30-40 billion parameters.

Q: How does the L40S compare to training-focused GPUs like the H100?
A: The L40S uses GDDR6 memory with 864 GB/s bandwidth versus H100's HBM3 at 3.35 TB/s, making it more cost-effective for inference workloads at lower batch sizes. The H100 is better suited for large-scale training and high-concurrency serving, while the L40S offers excellent price-performance for inference and fine-tuning tasks.

Q: Does the L40S support virtualization?
A: Yes, the L40S supports NVIDIA vGPU software and RTX Virtual Workstation (vWS) technology, enabling GPU resources to be shared across multiple virtual machines for remote workstation users and multi-tenant environments.

Q: What precision formats does the L40S support?
A: The L40S supports FP32, TF32, FP16, BFLOAT16, INT8, and FP8 precision formats. The fourth-generation Tensor Cores with Transformer Engine can dynamically switch between FP8 and FP16 to optimize performance and memory usage for AI workloads.
