# Modifying throughput capacity
<a name="increase-throughput-capacity"></a>

You can increase or decrease your file system's throughput capacity using the Amazon FSx console, the AWS Command Line Interface (AWS CLI), or the Amazon FSx API, as described in the following procedures.

## To modify a file system's throughput capacity (console)
<a name="increase-throughput-console"></a>

1. Open the Amazon FSx console at [https://console.aws.amazon.com/fsx/](https://console.aws.amazon.com/fsx/).

1. Navigate to **File systems**, and choose the Windows file system that you want to increase the throughput capacity for.

1. For **Actions**, choose **Update throughput**.

   Or, in the **Summary** panel, choose **Update** next to the file system's **Throughput capacity**. 

   The **Update throughput capacity** window appears.

1. Choose the new value for **Throughput capacity** from the list.

1. Choose **Update** to initiate the throughput capacity update.
**Note**  
Multi-AZ file systems fail over and fail back when updating throughput scaling, and are fully available. Single-AZ file systems experience a very brief period of unavailability during the update.

1. You can monitor the update progress on the **File systems** detail page, in the **Updates** tab.

   You can monitor the progress of the update by using the Amazon FSx console, the AWS CLI, and the API. For more information, see [Monitoring throughput capacity updates](monitoring-throughput-capacity-changes.md).

## To modify a file system's throughput capacity (CLI)
<a name="increase-throughput-cli"></a>

To increase or decrease a file system's throughput capacity, use the AWS CLI command [update-file-system](https://docs.aws.amazon.com/cli/latest/reference/fsx/update-file-system.html). Set the following parameters:
+ `--file-system-id` to the ID of the file system that you are updating.
+ `ThroughputCapacity` to the desired value; valid values are 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4608, 6144, 9216, 12288 MBps.

You can monitor the progress of the update by using the Amazon FSx console, the AWS CLI, and the API. For more information, see [Monitoring throughput capacity updates](monitoring-throughput-capacity-changes.md).
