An administrator configures FSx for ONTAP to use as storage in their cloud environment.

To address the issue of not being able to access an NFS file system hosted on FSx for ONTAP in one Virtual Private Cloud (VPC) from clients located in another VPC, the administrator should configure VPC peering between the two VPCs. Here’s why and how:

VPC Peering Setup:VPC peering allows two VPCs to communicate with each other as though they are part of the same network. This is essential for enabling direct access to the NFS file system across different VPCs.

Configure Network Routes:Once VPC peering is established, configure the network routes to ensure that traffic destined for the NFS file system can traverse the peered VPC connection.

Verify Accessibility:Test the NFS file system access from the client VPC to ensure that the configuration is correct and that the file system is accessible.

VPC peering is a straightforward solution that does not require the complexity and additional cost associated with options like Transit Gateways or Direct Connect. It’s well-suited for enabling direct network connectivity between VPCs within the same cloud provider.
