How to configure user storage quotas for the AWS Transfer Family on Amazon FSx for NetApp ONTAP

This article explains how to configure user storage quotas for AWS Transfer Family on Amazon FSx for NetApp ONTAP to prevent storage overconsumption and enforce fair resource allocation.

• Combines AWS Transfer Family, Directory Service, and FSx for ONTAP for enterprise file transfer
• Authentication via AWS Directory Service validates user identity before session establishment
• Authorization through IAM roles and logical directory mappings controls resource access
• Quota enforcement on FSx for ONTAP denies writes exceeding per-user storage limits in real time
• Create quota policies and rules via NetApp ONTAP CLI, not AWS Management Console
• Provision SFTP user home directories using S3 API to preserve directory hierarchy
• Create S3 access point on FSx for ONTAP volume for Transfer Family connectivity
• Configure IAM role granting Transfer Family permission to access S3 access point
• Validate quota enforcement by attempting file transfers exceeding user limits

This solution enables organizations to balance accessibility with storage control, preventing cost overages while ensuring fair resource distribution across multi-user file transfer environments.
