On Azure stack HCI servers with version 22H2 and forward there is the capability for GPU partitioning (GPU-P) which can be leveraged for different workloads such as artificial intelligence. Not all GPUs support partitioning, currently Dell supports partitioning on the A2 and A16 GPUs for Azure stack HCI servers. We strongly recommend using Windows Admin Center for GPU-P to avoid mistakes and for a streamlined visual experience.
Dell servers will not come with a GPU-P driver. The driver required for GPU-P requires separate licensing from NVIDIA, For more information about licensing options and benefits of GPU-P see: https://www.nvidia.com/en-us/data-center/virtual-solutions/. There is a host driver for GPUs partitioning and there's also a guest (VM) driver for GPU-P, without both drivers and the correct license activated GPU-P will not work.
Once both drivers are installed, Microsoft documentation on how to configure GPU-P can be found here: https://learn.microsoft.com/en-us/azure-stack/hci/manage/partition-gpu?tabs=windows-admin-center. It is highly recommended to use WAC and the GPU extension.
