Description

The NVIDIA L40S is a passively cooled, dual-slot full-height, full-length GPU accelerator with 48GB of ECC GDDR6 memory and a 350W power rating, supplied for the Cisco UCS X-Series platform. Built on the Ada Lovelace architecture with fourth-generation Tensor Cores, it is aimed at generative AI, LLM inference and graphics-intensive data centre workloads. It is supported in the UCS X440p PCIe Node on Riser Type A, making it suited to dense AI and compute deployments in X9508 chassis.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: Which Cisco platform is this GPU designed for?
A: It is supported in the Cisco UCS X-Series, specifically in the UCS X440p PCIe Node using Riser Type A (Riser 1A/2A Gen 4).

Q: How many L40S GPUs can be installed per node and chassis?
A: Up to two L40S GPUs can be installed per UCS X440p PCIe node, and up to 16 GPUs per X9508 chassis when using paired UCS 9416 X-Fabric modules.

Q: Is this GPU actively or passively cooled?
A: It is passively cooled, relying on chassis airflow within the UCS X-Series node rather than an onboard fan.

Q: What power connection and cabling does it need?
A: It uses a single 16-pin power connector and, in the UCS X440p node, requires the CBL-GPUH100-X440 cable.

Q: What workloads is the L40S suited to?
A: With 48GB of GDDR6 memory and fourth-generation Tensor Cores, it suits generative AI, LLM inference, AI training and graphics-intensive data centre workloads.
