Cannot create Standard_NC4as_T4_v3 compute instance despite having sufficient quota.

I successfully increased my quota for NCasT4v3 Series to 4 vCPUs in the West Europe region. However, when I try to create a GPU compute instance (Standard_NC4as_T4_v3), the interface incorrectly defaults to Standard_E4ds_v4 and fails to deploy the T4 GPU. I need assistance from the Azure team to force the provisioning of the correct Standard_NC4as_T4_v3 instance.

    Hello @ghada

    The most likely cause is an insufficient GPU quota. Verify the availability of the Standard_NC4as_T4_v3 series in West Europe, check both vCPU and GPU quotas, and explicitly specify the SKU during VM creation. If the GPU quota is 0, request an increase.

    Verify VM Availability in West Europe

    Use the Azure CLI to confirm the availability of the Standard_NC4as_T4_v3 series in the West Europe region.

    az vm list-skus --location "westeurope" --filter "name.starts_with('Standard_NC4as_T4_v3')" --output table

    If the command returns no results, the SKU is not available in that region.

    Verify Quota Details

    Check the quota limits for the NCasT4v3 series, specifically the GPU quota.

    az vm list-usage --location "westeurope" --output table

    Look for NcadsT4v3Family and GPUs. Ensure the GPU quota is at least 1. If the GPU quota is 0, request an increase.

    Specify the SKU During Deployment

    When creating the VM, explicitly specify the Standard_NC4as_T4_v3 SKU.

    Using Azure CLI:

    az vm create \ --resource-group MyResourceGroup \ --name MyGpuVm \ --location "westeurope" \ --image Ubuntu2204 \ --size "Standard_NC4as_T4_v3" \ --admin-username azureuser \ --generate-ssh-keys
