Microsoft Fabric capacity quotas

Microsoft Fabric provides limits, also known as quotas, which determine the maximum number of Fabric Capacity Units (CUs) for each of the capacities on your subscription. Quotas depend on your Azure subscription type. You don't get charged for quotas, you're only charged for your capacities.

This article explains how to view and increase your quotas, using the Azure portal and the Azure Resource Manager (ARM) APIs.

Prerequisites

• To view your Fabric quota, you need an Azure account with the contributor role, or another role that includes contributor access.

• To manage your Fabric quota, you need the permissions listed in Quota Request Operator

• Before provisioning your first capacity or if your quota is 0, register the Microsoft.Fabric resource provider using the Azure Resource Provider instructions

View your Fabric CU quota

The following section outlines how to view your Fabric quota using the Azure portal and the ARM APIs.

Azure

1. Sign in to the Azure portal

2. Search for quotas and select Quotas.

3. In the overview page, select Microsoft Fabric.

4. To see your usage records by subscription, select the following filters:

   • Provider - Microsoft Fabric.
   • Subscription - Select the subscription you want to see usage for.
   • Region - Select the region you want to see usage for.
   • Usage - Show all.

API

Use Fabric Capacities - List Usages to check your current usage and quota.

You need three parameters to make the call:

• location - The name of the Azure region. If you don't know the name of your region, you can use the Region - List By Service API to find it.

• subscriptionId - The ID of the target subscription. The value must be an UUID.

• api-version - The API version to use for this operation. The only supported version is 2023-11-01

Response example

Here's an example of the response you get when you call the API.

{
    "value": [
        {
            "name": {
                "value": "CapacityQuota",
                "localizedValue": "CapacityQuota"
            },
            "unit": "CU",
            "currentValue": 256,
            "limit": 280,
            "id": null
        }
    ]
}

Calculate your quota

Your available quota is the difference between limit and CurrentValue.

• limit - Identifies the quota limit of your subscription.

• CurrentValue - Determines the number of used CUs.
