Cisco UCSX-GPU-L4-MEZZ | NVIDIA L4 Tensor Core GPU, 24GB GDDR6, 70W, PCIe Gen4

Q: Which Cisco UCS systems support the UCSX-GPU-L4-MEZZ?
A: The UCSX-GPU-L4-MEZZ is compatible with Cisco UCS X-Series compute nodes including the X210c M7, X210c M8, and X215c M8. It installs in the front mezzanine slot and requires a compatible front mezzanine adapter. For GPU PCIe Node configurations, a rear mezzanine adapter is also required.

Q: What workloads is the NVIDIA L4 GPU optimized for?
A: The L4 is optimized for AI inference workloads including generative AI, large language models, video transcoding and AI video analytics, virtual desktop infrastructure (VDI), graphics virtualization, and real-time rendering. It delivers up to 2.5x more generative AI performance compared to the previous-generation T4 GPU while maintaining the same 70W power envelope.

Q: How does the mezzanine form factor benefit deployment?
A: The mezzanine form factor integrates directly into the UCS X-Series compute node architecture via the front mezzanine slot, eliminating the need for separate PCIe riser cards and simplifying GPU deployment. This design reduces cabling complexity, improves airflow, and allows for flexible GPU configurations within the modular UCS X-Series chassis.

Q: Can multiple UCSX-GPU-L4-MEZZ modules be installed in a single compute node?
A: Yes, depending on the compute node model and mezzanine configuration, up to two UCSX-GPU-L4-MEZZ GPUs can be installed using the appropriate front mezzanine adapter with dual GPU support. GPU mixing is not supported—all GPUs in a node must be the same model.

Q: What are the power requirements for the UCSX-GPU-L4-MEZZ?
A: The L4 GPU has a 70W thermal design power and draws power directly through the mezzanine connector from the UCS compute node. No auxiliary PCIe power cables are required. This low power consumption enables high-density GPU deployments without requiring chassis power infrastructure upgrades.
