Easy Hierarchical Storage Management

Keep the right data on the right storage at the right time

Maximise free space on your fast online storage, and decommission stale data to a slower nearline storage tier using integrated Data Replication and Space Reclaiming in the Tiger Series server-class solutions.

In assigning the right data to the right type of storage – moving less-critical data to slower and less expensive tiers without causing orphan links – the Data Replication & Space Reclaiming mechanism helps users and administrators optimize use of the fastest and most expensive tiers of shared storage.

Data Replication

You can set any SMB/CIFS share accessible to Tiger Box/Tiger Serve as a replication volume. You should then simply specify what data on the fastest storage should be migrated to the replication volume by setting two parameters – what data is stored (all data on the storage, all data except data in specific folders or just data in specific folders) and time since modification. Any file that matches the criteria you specify is queued for replication. To ensure that the replication process doesn’t hinder users, the Replication process is performed in the background, and only when system resources are idle.

Space Reclaiming

By default, replicated data is available on both the Tiger Series source storage and the replication volume. To minimize storage usage, Tiger Technology offers you an integrated mechanism for reclaiming space. It automatically replaces a replicated file with a stub file that points to the actual file on the replication volume. Similar to the replication policy, this mechanism uses simple criteria that govern what already replicated data should be reclaimed from the fast storage, leaving just its copy on the replication volume.

Data purged from the Tiger Series faster storage is always accessible to users and applications by using the same paths, as if it has not moved. Attempting to access the stub file triggers an immediate restore of the source file from the replication volume.

You can fine-tune the space reclaiming mechanism by triggering it only when the main storage exceeds a specified capacity threshold. You can also set used space thresholds as triggers for deletion of all replicated files (regardless of their size). You can thus achieve optimal utilization of your storage, ensuring that there are no duplicated files.

You can also use the integrated Browser to manually replicate files, folders, and projects, and restore them from the replication volume, permanently delete them or restore them on the faster online volume.
