Cisco UCSC-GPU-L40 | L40 GPU 48GB GDDR6, 300W, PCIe Gen4, 2-Slot FHFL

Q: What server platforms support the UCSC-GPU-L40?
A: The UCSC-GPU-L40 is designed for Cisco UCS C-Series rack servers with PCIe Gen4 x16 slots and adequate power and cooling capacity. It requires a 2-slot full-height, full-length PCIe slot and supports specific riser configurations depending on the server model.

Q: What workloads is the L40 GPU optimized for?
A: The L40 excels at AI inference and training, virtual workstation (VDI) deployments with vGPU support, real-time ray tracing and 3D rendering, video transcoding with hardware AV1 encode/decode, and graphics-intensive data center applications requiring 48GB of memory.

Q: How does the L40 compare to the L40S?
A: The L40 provides 300W TDP with 90.5 TFLOPS FP32 and 181 TFLOPS TF32 Tensor performance. The L40S is a higher-performance variant with 350W TDP and nearly double the Tensor Core performance for generative AI workloads, while both share 48GB GDDR6 memory and Ada Lovelace architecture.

Q: Does the L40 support multi-user virtualization?
A: Yes, the L40 supports NVIDIA vGPU software for virtual workstations (vWS) and virtual PC/app deployments, enabling multiple users to share GPU resources with hardware-level isolation in multi-tenant data center and cloud environments.

Q: What cooling and power requirements does the UCSC-GPU-L40 have?
A: The UCSC-GPU-L40 is a passively cooled GPU requiring adequate server airflow to maintain thermal performance. It draws a maximum of 300W and requires appropriate PCIe power connectors and sufficient power supply capacity in the host UCS server.
