The hospital "DRK Krankenhaus Chemnitz-Rabenstein" had implemented a two tiered HSM architecture by PoINT Storage Manager. Within this architecture data can be archived in an automated manner to cost-effective secondary storage and thus expensive primary storage can be off-loaded. Furthermore the backup-volume is decreased significantly by the archiving process whereby cost can be saved and backup-windows can be met. By the built-in migration functionality of PoINT Storage Manager the migration of the remaining data to the new SAS storage system was carried out transparently and without any business interruption.
Challenges
- Archiving of PACS data from the iSCSI hard disk system to 48-slot tape library
- Chronological data gradually stored on tape
- Transparent and uninterruptible migration to the the new primary storage
Solution- PoINT Storage Manager
Archiving
- Implementation of a two tiered HSM architecture based on PoINT Storage Manager
- Automated archiving from an iSCSI based hard disk system to a 48-slot tape library
- Data archived gradually on tape
Migration
- Data of the primary storage is being migrated to the new SAS storage by built-in migration functionality of PoINT Storage Manager
- Archived data can be accessed via the primary storage system by "stubs" and selective re-storing on demand
Advantages
- Efficient use of primary storage by migration of inactive data
- All data permanently available by file system access to primary storage
- Cost and time savings through reduced data volume and backup time of the primary storage
- Data Secuirty by using different storage technologies within the archive tier
- Transparent migration without significant downtime
