Cisco UCSX-GPU-FLX140MZ | Intel Flex 140 GPU, 12GB GDDR6, 75W, PCIe Gen4 x8 Mezz

Q: Which Cisco UCS systems support this GPU?
A: The UCSX-GPU-FLX140MZ mezzanine GPU is designed specifically for Cisco UCS X-Series compute nodes including the X210c M7, X210c M8, X215c M8, and X410c M7. It installs in the front mezzanine slot of these compute nodes, which must be deployed within a UCS X9508 modular chassis. This GPU cannot be mixed with other GPU types in the same configuration.

Q: How many VDI sessions can this GPU support?
A: The Intel Flex 140 GPU can support up to 12 typical knowledge-worker VDI sessions per card, making it ideal for high-density VDI deployments. With hardware-based SR-IOV supporting up to 62 virtual functions, the GPU enables flexible resource allocation for office productivity, video, and browser workloads with low-to-moderate graphics requirements.

Q: What workloads is the Intel Flex 140 GPU optimized for?
A: This GPU is optimized for Virtual Desktop Infrastructure (VDI), cloud gaming, media processing and delivery, AI visual inference, and lighter AI models such as simple object detection. With four hardware media engines and 16 Xe cores in a 75W envelope, it excels at media transcoding and GPU-accelerated virtual desktops while maintaining energy efficiency in data center environments.

Q: Can I mix this GPU with NVIDIA GPUs in the same system?
A: No, mixing GPU types is not allowed. If you are using a PCIe node with a GPU front mezzanine configuration, only matching GPU combinations are supported (for example, UCSX-GPU-FLEX140 standard card paired with UCSX-GPU-FLX140MZ mezzanine). All GPUs within the same UCS X-Series configuration must be of the same model.

Q: What hypervisors and operating systems are supported?
A: The Intel Flex 140 GPU supports VMware vSphere ESXi with SR-IOV drivers for virtual GPU sharing, as well as Linux distributions including Ubuntu, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server. Note that Windows Server 2019 is not supported with Intel Flex 140 and 170 GPUs. The GPU includes native support for oneAPI, OpenCL 3.0, OpenGL 4.6, and DirectX 12 Ultimate.
