Optimizing performance with Amazon FSx maintenance windows - FSx for ONTAP

Optimizing performance with Amazon FSx maintenance windows

As a fully-managed service, FSx for ONTAP regularly performs maintenance on and updates to your file system. This maintenance has no impact for most workloads. For workloads that are performance-sensitive, on rare occasions you may notice a brief (<60 seconds) impact on performance when maintenance is occurring; Amazon FSx enables you to use the maintenance window to control when any such potential maintenance activity occurs.

Patching occurs infrequently, typically once every several weeks. Patching should require only a fraction of your 30-minute maintenance window. During these few minutes of time, your Multi-AZ file systems automatically fail over and fail back.

You choose the maintenance window during file system creation. If you have no time preference, then a 30-minute default window is assigned.

Note

To ensure data integrity during maintenance activity, FSx for ONTAP completes any pending write operations to the underlying storage volumes hosting your file system before maintenance begins.

You can use the Amazon FSx Management Console, AWS CLI, AWS API, or one of the AWS SDKs to change the maintenance window for your file systems.
