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. For scale-up file systems, patching typically only requires 30 minutes from the start of your maintenance window. For scale-out file systems, patching requires up to 90 minutes from the start of your maintenance window. During these few minutes, your 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 start time is assigned.

FSx for ONTAP allows you to adjust your maintenance window as needed to accommodate your workload and operational requirements. You can move your maintenance window as frequently as required, provided that a maintenance window occurs at least once every 14 days. If a patch is released and a maintenance window does not occur within 14 days, FSx for ONTAP will proceed with maintenance on the file system to ensure its security and reliability.

Note

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

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