With this update, participant accounts in an AWS organization can create Multi-AZ OpenZFS file systems within VPCs shared by owner accounts. Previously, Multi-AZ configurations were limited to VPCs owned by the participant account, restricting architectural flexibility.

This capability allows decentralized resource management while maintaining high availability across availability zones. It supports all regions offering Amazon FSx for OpenZFS and facilitates easier administration by separating network control from storage provisioning within enterprise environments.
