The procedures are different for classic file shares, which use the Microsoft.Storage resource provider, versus file shares created with Microsoft.FileShares (preview). ## Change the cost and performance characteristics of a classic file share After creating your classic file share, you might need to adjust the provisioning (provisioned models) or access tier (pay-as-you-go model) of the share. The following sections show you how to adjust the relevant properties for your share. ### Change the cost and performance characteristics of a provisioned v2 classic file share After creating your provisioned v2 classic file share, you can change one or all three of the provisioned quantities of your file share. The amount of storage, IOPS, and throughput you provision can be dynamically scaled up or down as your needs change. However, you can only decrease a provisioned quantity after 24 hours have elapsed since your last quantity increase. Storage, IOPS, and throughput changes are effective within a few minutes after a provisioning change. # [Portal](#tab/azure-portal) Follow these instructions to update the provisioning for your file share. 1. Go to your storage account. From the service menu, under **Data storage**, select **File shares**. 2. In the file share listing, select the file share for which you desire to change the provisioning. 3. In the file share overview, select **Change size and performance**.  4. The **Size and performance** pop out dialog has the following options:  - **Provisioned storage (GiB)**: The amount of storage provisioned on the share. - **Provisioned IOPS and throughput**: A radio button group that lets you select between _Recommended provisioning_ and _Manually specify IOPS and throughput_. If your share is at the recommended IOPS and throughput level for the amount of storage provisioned, _Recommended provisioning_ will be selected; otherwise, _Manually specify IOPS and throughput_ will be selected. You can toggle between these two options depending on your desire to change share provisioning. - **IOPS**: If you select _Manually specify IOPS and throughput_, this textbox enables you to change the amount of IOPS provisioned on this file share. - **Throughput (MiB/sec)**: If you select _Manually specify IOPS and throughput_, this textbox enables you to change the amount of throughput provisioned on this file share. 5. Select **Save** to save provisioning changes. Storage, IOPS, and throughput changes are effective within a few minutes after a provisioning change. # [PowerShell](#tab/azure-powershell) You can modify a provisioned v2 file share with the `Update-AzRmStorageShare` cmdlet. Remember to replace the values for the variables `$resourceGroupName`, `$storageAccountName`, `$shareName`, `$provisionedThroughputMibPerSec`, `$provisionedIops`, and `$provisionedStorageGib` with the desired values for your file share. ```powershell # The path to the file share resource to be modified. $resourceGroupName = "<my-resource-group>" $storageAccountName = "<my-storage-account-name>" $shareName = "<name-of-the-file-share>" # The provisioning desired on the file share. Delete the parameters if no # change is desired. $provisionedStorageGib = 10240 $provisionedIops = 10000 $provisionedThroughputMibPerSec = 2048 # Update the file share provisioning. Update-AzRmStorageShare ` -ResourceGroupName $resourceGroupName ` -AccountName $storageAccountName ` -ShareName $shareName ` -QuotaGiB $provisionedStorageGib ` -ProvisionedIops $provisionedIops ` -ProvisionedBandwidthMibps $provisionedThroughputMibPerSec $f = Get-AzRmStorageShare -ResourceGroupName $resourceGroupName -AccountName $storageAccountName -ShareName $shareName $f | fl ``` # [Azure CLI](#tab/azure-cli) You can modify a provisioned v2 file share with the `az storage share-rm update` command. Remember to replace the values for the variables `resourceGroupName`, `storageAccountName`, `fileShareName`, `provisionedStorageGib`, `provisionedIops`, and `provisionedThroughputMibPerSec` with the desired values for your file share. ```bash # The path to the file share resource to be modified. resourceGroupName="<resource-group>" storageAccountName="<storage-account>" fileShareName="<file-share>" # The provisioning desired on the file share. Delete the parameters if no # change is desired. provisionedStorageGib=10240 provisionedIops=10000 provisionedThroughputMibPerSec=2048 # Update the file share provisioning. az storage share-rm update \ --resource-group $resourceGroupName \ --name $shareName \ --storage-account $storageAccountName \ --quota $provisionedStorageGib \ --provisioned-iops $provisionedIops \ --provisioned-bandwidth-mibps $provisionedThroughputMibPerSec ``` --- ### Change the cost and performance characteristics of a provisioned v1 classic file share After creating your provisioned v1 file share, you can change the provisioned storage size of the file share. Changing the provisioned storage of the share will also change the amount of provisioned IOPS and provisioned throughput. You can only decrease the provisioned storage after 24 hours have elapsed since your last storage increase. Storage, IOPS, and throughput changes are effective within a few minutes after a provisioning change. For more information, see [provisioned v1 provisioning detail](./understanding-billing.md#provisioned-v1-provisioning-detail). # [Portal](#tab/azure-portal) Follow these instructions to update the provisioning for your file share. 1. Go to your storage account. From the service menu, under **Data storage**, select **File shares**. 2. In the file share listing, select the file share for which you desire to change the provisioning. 3. In the file share overview select **Change size and performance**.  4. The **Size and performance** pop out dialog has a single option, **Provisioned storage (GiB)**. If you require more IOPS or throughput than the given amount of provisioned storage provides, you can increase your provisioned storage capacity to get additional IOPS and throughput.  5. Select **Save** to save provisioning changes. Storage, IOPS, and throughput changes are effective within a few minutes after a provisioning change. > [!NOTE] > You can use PowerShell and CLI to enable/disable paid bursting if desired. Paid bursting is an advanced feature of the provisioned v1 billing model. See [provisioned v1 paid bursting](./understanding-billing.md#provisioned-v1-paid-bursting) before enabling paid bursting. # [PowerShell](#tab/azure-powershell) You can modify a provisioned v1 file share with the `Update-AzRmStorageShare` cmdlet. Remember to replace the values for the variables `$resourceGroupName`, `$storageAccountName`, and `$fileShareName` with the desired values for your file share. Set `$provisionedStorageGib`, `$paidBurstingEnabled`, `$paidBurstingMaxIops`, and `$paidBurstingMaxThroughputMibPerSec` to non-null (`$null`) values on the file share. Paid bursting is an advanced feature of the provisioned v1 model. See [provisioned v1 paid bursting](./understanding-billing.md#provisioned-v1-paid-bursting) before enabling. ```PowerShell # The path to the file share resource to be modified. $resourceGroupName = "<resource-group>" $storageAccountName = "<storage-account>" $fileShareName = "<file-share>" # The provisioning desired on the file share. Set to $null to keep at the # current level of provisioning. $provisionedStorageGib = 10240 # Paid bursting settings. $paidBurstingEnabled = $null # Set to $true or $false. $paidBurstingMaxIops = $null # Set to an integer value. $paidBurstingMaxThroughputMibPerSec = $null # Set to an integer value. # Configure parameter object for splatting. $params = @{ ResourceGroupName = $resourceGroupName; StorageAccountName = $storageAccountName; Name = $fileShareName; } if ($null -ne $provisionedStorageGib) { $params += @{ QuotaGiB = $provisionedStorageGib } } if ($null -ne $paidBurstingEnabled) { $params += @{ PaidBurstingEnabled = $paidBurstingEnabled } } if ($null -ne $paidBurstingMaxIops) { $params += @{ PaidBurstingMaxIops = $paidBurstingMaxIops } } if ($null -ne $paidBurstingMaxThroughputMibPerSec) { $params += @{ PaidBurstingMaxBandwidthMibps = $paidBurstingMaxThroughputMibPerSec } } # Update the file share provisioning. Update-AzRmStorageShare @params ``` # [Azure CLI](#tab/azure-cli) You can modify a provisioned v1 file share with the `az storage share-rm update` command. Remember to replace the values for the variables `resourceGroupName`, `storageAccountName`, `fileShareName`, and `provisionedStorageGib` with the desired values for your file share. ```bash # The path to the file share resource to be modified. resourceGroupName="<resource-group>" storageAccountName="<storage-account>" fileShareName="<file-share>" # The provisioning desired on the file share. provisionedStorageGib=10240 # Update the file share provisioning. az storage share-rm update \ --resource-group $resourceGroupName \ --storage-account $storageAccountName \ --name $fileShareName \ --quota $provisionedStorageGib ``` To toggle paid bursting, use the `--paid-bursting-enabled` parameter. Paid bursting is an advanced feature of the provisioned v1 model. See [provisioned v1 paid bursting](./understanding-billing.md#provisioned-v1-paid-bursting) before enabling. You can optionally use the `--paid-bursting-max-iops` and `--paid-bursting-max-bandwidth-mibps` flags to set a restriction on the upper amount of paid bursting allowed for cost control purposes. Remember to replace the values for the variables `resourceGroupName`, `storageAccountName`, and `fileShareName` with the desired values for your file share. ```bash resourceGroupName="<resource-group>" storageAccountName="<storage-account>" fileShareName="<file-share>" az storage share-rm update \ --resource-group $resourceGroupName \ --storage-account $storageAccountName \ --name $fileShareName \ --paid-bursting-enabled true ``` --- ### Change the cost and performance characteristics of a pay-as-you-go classic file share After you've created your pay-as-you-go file share, there are two properties you might want to change: - **Access tier**: The access tier of the file share dictates to the ratio of storage to IOPS/throughput costs (in the form of transactions). There are three access tiers: _transaction optimized_, _hot_, and _cool_. Changing the tier of the Azure file share results in transaction costs for the movement to the new access tier. For more information, see [switching between access tiers](./understanding-billing.md#switching-between-access-tiers). - **Quota**: Quota is a limit on the size of the file share. The quota property is used in the provisioned v2 and provisioned v1 models to mean "provisioned storage capacity", however, in the pay-as-you-go model, quota has no direct impact on billing. The two primary reasons you might want to modify this are if you use quota to limit the growth of your file share to keep control of the used storage/transaction costs in the pay-as-you-go model, or if you have a storage account predating the introduction of the large file share feature, which enabled file shares to grow beyond 5 TiB. The maximum file share size for a pay-as-you-go file share is 100 TiB. # [Portal](#tab/azure-portal) Follow these instructions to update the access tier of your file share using the Azure portal. 1. Go to your storage account. From the service menu, under **Data storage**, select **File shares**. 2. In the file share listing, select the file share for which you desire to change the access tier. 3. In the file share overview, select **Change tier**. 4. Select the desired **Access tier** from the provided drop-down list. 5. Select **Apply** to save the access tier change. For these instructions to update the quota of your file share. 1. Go to your storage account. From the service menu, under **Data storage**, select **File shares**. 2. In the file share listing, select the file share for which you desire to change the quota. 3. In the file share overview, select **Edit quota**. 4. In the edit quota pop-out, enter the desired maximum size of the share or select **Set to maximum**. There is no cost implication of setting the share to the maximum size. 5. Select **OK** to save quota changes. The new quota is effective within a few minutes. # [PowerShell](#tab/azure-powershell) You can modify the access tier and quota settings of a pay-as-you-go file share with the `Update-AzRmStorageShare` cmdlet. Remember to replace the values for the variables `$resourceGroupName`, `$storageAccountName`, `$fileShareName`, `$accessTier`, and `$quotaGib` with the desired values for your file share. ```PowerShell # The path to the file share resource to be modified. $resourceGroupName = "<resource-group>" $storageAccountName = "<storage-account>" $fileShareName = "<file-share>" # The settings to be changed on the file share. Set to $null to skip setting. $accessTier = "Cool" $quotaGib = $null # Construct a parameters hash table for cmdlet splatting. $updateParams = @{ ResourceGroupName = $resourceGroupName StorageAccountName = $storageAccountName Name = $fileShareName } if ($null -ne $accessTier) { $updateParams += @{ AccessTier = $accessTier } } if ($null -ne $quotaGib) { $updateParams += @{ QuotaGiB = $quotaGib } } # Update the file share Update-AzRmStorageShare @updateParams ``` # [Azure CLI](#tab/azure-cli) You can modify the access tier and quota settings of a pay-as-you-go file share with the `az storage share-rm update` command. Remember to replace the values for the variables `resourceGroupName`, `storageAccountName`, `fileShareName`, `accessTier`, and `quotaGib` with the desired values for your file share. ```bash # The path to the file share resource to be modified. resourceGroupName="<resource-group>" storageAccountName="<storage-account>" fileShareName="<file-share>" # The settings to be changed on the file share. Set to the empty string to skip # setting. accessTier="Cool" quotaGib="" command="az storage share-rm update --resource-group $resourceGroupName" command="$command --storage-account $storageAccountName --name $fileShareName" if [ ! -z "${accessTier}" ]; then command="$command --access-tier $accessTier" fi if [ ! -z "${quotaGib}" ]; then command="$command --quota $quotaGib" fi # Update file share (command is in variable) $command ``` --- ## Change the cost and performance characteristics of a file share (Microsoft.FileShares) > [!NOTE] > File share with Microsoft.FileShares is currently in preview.
