AWS::FSx::FileSystem DiskIopsConfiguration

The SSD IOPS (input/output operations per second) configuration for an Amazon FSx for NetApp ONTAP, Amazon FSx for Windows File Server, or FSx for OpenZFS file system. By default, Amazon FSx automatically provisions 3 IOPS per GB of storage capacity. You can provision additional IOPS per GB of storage. The configuration consists of the total number of provisioned SSD IOPS and how it is was provisioned, or the mode (by the customer or by Amazon FSx).


To declare this entity in your Amazon CloudFormation template, use the following syntax:


{ "Iops" : Integer, "Mode" : String }


Iops: Integer Mode: String



The total number of SSD IOPS provisioned for the file system.

The minimum and maximum values for this property depend on the value of HAPairs and StorageCapacity. The minimum value is calculated as StorageCapacity * 3 * HAPairs (3 IOPS per GB of StorageCapacity). The maximum value is calculated as 200,000 * HAPairs.

Amazon FSx responds with an HTTP status code 400 (Bad Request) if the value of Iops is outside of the minimum or maximum values.
