Enhancements

Each release offers new functionalities and improvements. Read this information for a high-level summary of major enhancements introduced in the Fusion Data Foundation 4.21 release.

HCP clusters

Fusion Data Foundation support for HCP clusters

Fusion Data Foundation is supported on hosted (HCP) clusters running OpenShift® Container Platform versions N, N-1, N-2, N-3, and N-4, where N represents the OpenShift Container Platform version deployed on the hub cluster.

Disaster Recovery

Enhanced protected applications list view for disaster recovery

The protected Applications page shows managed (ApplicationSet and Subscription) and discovered applications together, providing a complete view of all workloads protected by disaster recovery. Multi-selection is enabled in the list view, laying the groundwork for grouped failover, relocate, and disable-DR operations for managed applications.

Automatic resource cleanup for discovered VMs during disaster recovery operations

Disaster recovery workflows now automatically remove resources associated with DR-protected virtual machines during failover or relocate operations. This automation applies only to the discovered virtual machines enrolled for protection through Red Hat® Advanced Cluster Management for Kubernetes Fleet Virtualization and helps reduce manual steps while improving transition efficiency.

For more information, see Virtual machine garbage collection automation.

Multicloud Object Gateway

Minimal IAM support for Multicloud Object Gateway

Minimal IAM support is now available in the Multicloud Object Gateway to provide improved access control for multi-tenant environments. This enhancement enables administrators to define and manage user-level permissions more effectively, supporting scenarios where data scientists and other user groups require isolated and governed access to object storage resources. The feature lays the groundwork for more secure, flexible multi-tenant deployments by ensuring that users interact only with the buckets and operations they are authorized to access.

For more information, see Creating and managing IAM user.

Enhanced Multicloud Object Gateway database backup

Multicloud Object Gateway database backup is enhanced to provide more reliable protection against data loss and to complement the high-availability capabilities. The update adds support for automated scheduled backups with configurable frequency (daily, weekly, or monthly) and retention settings along with on-demand backup options through the MCG CLI or CRD. The UI now displays the time of the most recent backup and offers advanced configuration for Multicloud Object Gateway backup management. The system supports internal, external, and standalone Multicloud Object Gateway deployments by automatically detecting or allowing selection of snapshot StorageClasses.

To configure Multicloud Object Gateway database backup, refer to the deployment procedures for your specific platform.

Developer access to the Fusion Data Foundation object browser

Developer-level users can now be granted access to the Fusion Data Foundation object browser, enabling them to view and manage only their own object storage resources with restricted permissions. This enhancement supports flexible, role-appropriate access control and allows development teams to work more independently while preserving administrative boundaries.

For more information, see Accessing the object browser.

Support for internal mode RGW with object browser

The object browser now supports browsing, uploading, downloading, and managing RGW object. Operations include listing and creating buckets, navigating objects in a folder-like view, uploading files or directories, downloading objects, generating presigned URLs, viewing metadata, filtering and sorting results, previewing content, and creating prefixes. Bucket-level capabilities such as configuring expiration and access policies are also available.

For more information, see Creating and managing buckets using the object browser.
