Data Protection for IBM z Systems

Ultimate data protection, backup and archiving

ETERNUS CS8000, the data protection appliance from FUJITSU, shows a record of success in mainframe environments since 1999. The appliance is used around the world by the largest data centres in data-intensive segments such as financial services, insurance, telecommunication, public administration, industry and IT service provisioning. Its ongoing development has continued for many years in close collaboration with a well-established user group. That translates into optimal support and keen awareness of the demands arising from daily system use – based on real-world best practices.

Fujitsu ETERNUS CS8000 - True Tape Virtualization

The FUJITSU CS8000 makes the cross-media mix of disk and tape technology most efficient, to benefit from the best of both worlds. For the mainframe host, the appliance appears as a virtual tape library (VTL) – in addition the unified ETERNUS CS8000 platform provides intelligent management of cross-media mix – known as automated Information Lifecycle Management (ILM). The appliance combines the strengths of disk and tape with rule-based management, providing seamless and automated backup-to-disk-to tape (B2D2T) processes.

The ETERNUS CS8000 offers the highest degree of flexibility in the market. It supports mainframe and Open Systems backup and archiving, as well as disk-only, B2D2T, and VTL with deduplication functionality with the same appliance.

Ensure highest levels of data availability

To ensure the availability of business-critical data from the mainframe environment, ETERNUS CS8000 provides the highest level of data protection possible.

Highly available appliance ensures backup processes:

To terminate complex, time-consuming and error prone tape management, ETERNUS CS8000 takes over the management of all target systems, providing a highly available virtualised tape robot. The redundant architecture enables reception of the backup data, even if a component should fail, e.g. if the physical tape fails, then the data will automatically be directed to another tape drive or tape library to ensure that the data is safe.

Tape reorganisation and self-healing:

The tape reorganisation function effectively utilises the capacity available. Furthermore, regular reorganisation of tape media refreshes the magnetisation. The appliance automatically makes quality checks of duplicate copies. If an error occurs, the self-healing functionality recovers the inaccessible information from the other copy to ensure the availability of data even over the very long-term.

The self-healing plays also an important role if a copy is requested for a restore case and not available for some reason. The recall request is automatically redirected to the second copy, the data is provided and the job for the backup software is completed. In addition the automated self-healing recovers the failed copy. Thus the level of redundancy is restored.

Flexible copy management:

ETERNUS CS8000 manages different levels of data availability. Data can be mirrored between two sites, replicated over very long distances and saved as multiple copies. This function is user-defined and policy-based.

Automated continuation with cache mirror:

The core element of the most disaster resilient architecture is one logical ETERNUS CS8000 system which is deployed over two geographically separated sites, the so called “split-site” configuration with “cache mirror”. The internal infrastructure is thereby extended to a second site. The host still sees one logical setup, without being aware of the geographical location. The result is a system which no single point of failure, which continues to run even after a complete site failure. Our cluster will stretch to up to 100km.

Investment protection

ETERNUS CS8000 is based on a modular architecture. Independent building blocks provide a genuine scale-out platform in both capacity and performance.

Tape libraries are decoupled from the backup software. A wide range of libraries and tape drives are supported. Even if the libraries and drives are different, they can be connected in parallel. This makes it very easy to introduce a new generation of tape libraries or tape drives. ETERNUS CS8000 takes care of the data migration, from the old library to the new.

Consolidation of mainframe and open system environments

Furthermore, ETERNUS CS8000 is a unified data protection appliance for all applications and the complete physical and virtual server environment, comprising mainframe and open systems. Flexible VTL and NAS support integrates backup, archiving, compliant archiving and second-tier file storage, while supporting the complete consolidation of heterogeneous environments -resources are leveraged and the costs are dramatically reduced.
