subnetIds

Specifies the IDs of the subnets that the file system will be accessible from. For Windows and ONTAP MULTI_AZ_1 deployment types,provide exactly two subnet IDs, one for the preferred file server and one for the standby file server. You specify one of these subnets as the preferred subnet using the WindowsConfiguration > PreferredSubnetID or OntapConfiguration > PreferredSubnetID properties. For more information about Multi-AZ file system configuration, see Availability and durability: Single-AZ and Multi-AZ file systems in the Amazon FSx for Windows User Guide and Availability and durability in the Amazon FSx for ONTAP User Guide.

For Windows SINGLE_AZ_1 and SINGLE_AZ_2 and all Lustre deployment types, provide exactly one subnet ID. The file server is launched in that subnet's Availability Zone.
