Cisco HCIX-GPU-L40 | NVIDIA L40 GPU, 48GB GDDR6, 300W, PCIe 4.0 x16

Q: What workloads is the NVIDIA L40 GPU optimized for?
A: The NVIDIA L40 is optimized for AI inference, virtual workstation deployments with NVIDIA vGPU software, 3D rendering and visualization, real-time ray tracing, video transcoding with AV1 support, and professional graphics applications. It balances compute performance with visual computing capabilities in a single accelerator.

Q: Which Cisco systems support the HCIX-GPU-L40?
A: The HCIX-GPU-L40 is designed for Cisco Compute Hyperconverged infrastructure, specifically the HCIX-440P PCIe Node within the Cisco Compute Hyperconverged 9508 Chassis. It requires Riser Type A (FHFL GPU support) and connects to compute nodes via Cisco X-Fabric Technology with 9416 X-Fabric modules.

Q: Does the L40 support GPU virtualization?
A: Yes, the NVIDIA L40 fully supports NVIDIA vGPU software for virtual workstation (vWS) and virtual PC/application (vApps) deployments, enabling secure multi-tenant GPU sharing and remote graphics acceleration for virtual desktop infrastructure and cloud workloads.

Q: What is the difference between the L40 and L40S?
A: The L40S is a higher-performance variant with nearly double the Tensor Core performance for AI workloads, increased TDP from 300W to 350W, and enhanced AI inference capabilities. The L40 offers a better balance for mixed graphics and AI workloads at lower power consumption.

Q: How many L40 GPUs can be installed per node?
A: The HCIX-440P PCIe Node supports up to two NVIDIA L40 GPUs when equipped with Riser Type A. Each GPU requires a full-height full-length dual-slot configuration and connects via PCIe Gen 4 x16 interface through the X-Fabric interconnect.
