Backup for IBM® z Systems – by the creators of the “world’s fastest and most reliable data protection platform”

For a mainframe host the ETERNUS CS8000 appears as a (virtual) tape library with up to 1,280 virtual tape drives and 3 million virtual cartridges, automatically creating copies (policy-based), storing them either on disk, deduplication disk and/or tape.

ETERNUS CS8000 is based on a highly modular architecture providing FICON® and FC connectivity. Independent building blocks provide a genuine industry-leading scale-out platform in both: capacity (from 19 TB up to 96 Petabyte net usable on disk) and performance (from 8 TB/h up to 150 TB/h for backup and recovery speed).

Data availability and 24/7 operation is ensured by intelligent data management, synchronous or asynchronous data replication to remote locations and by a comprehensive set of automated functionalities like automatic failover, tape refresh and self-healing.

Reducing complexity in your tape infrastructure

Attaching physical tape infrastructure as an option is transparent to the mainframe host. A wide range of enterprise tape drives and tape libraries (e.g. from IBM®, Oracle®/StorageTek®, Quantum®, Spectralogics® and Fujitsu) are supported, but also LTO® tape drives as well.

Even if libraries and drives are different, they can be connected to ETERNUS CS8000 in parallel. This makes it very easy to introduce the latest generation of tape libraries or tape drives – the appliance takes care for policy-based automated data migration, from the old technology to the new one. This guarantees a fully freed of choice for vendors and technologies, investment protection and ongoing savings from coming technology changes.

Ultimate availability

To ensure the availability of business-critical data from the mainframe environment, the ETERNUS CS8000 provides the highest level of data protection possible, nearly zero-downtime. The core element of the most disaster resilient architecture is one ETERNUS CS8000 system which is deployed over two geographically separated sites, the so called “split-site” configuration with “synchronous cache mirror”. The internal infrastructure is thereby extended to a second site (our cluster will stretch to up to 100 km). While the host still sees one logical setup, the result is a system with no single point of failure, which continues to run even after a complete site failure.

Business Benefits

Fujitsu’s ETERNUS CS8000 is unique on the market and more than just an alternative to your current backup infrastructure for IBM Mainframes.

True Tape Virtualization

  • Gives full freedom of choice with regards to the Tape Technology and Vendor: High-Performance and Capacity drives from IBM and Oracle/ StorageTek, or low cost LTO technology, and also in a mix.
    Through its high level of automation (e.g. for tape media re-organization, -refresh and -migration) ETERNUS CS8000 allows you to also benefit from savings potential on future tape technologies.

Combined use of Deduplication and Tape

  • Fujitsu’s patented variable blocksize data deduplication algorithm allows you to reduce the required capacity to its minimum. ETERNUS CS8000 is the only Virtual Tape appliance that allows you to benefit from a synchronous mirroring. Even more unique: ETERNUS CS8000 allows you to automatically create multiple and also remote copies of your data on tape. This helps not only to reduce cost but adds more data safety by using a media mix including tape.

24x7 Non-Stop operations for mission critical data

  • ETERNUS CS8000 is designed for continued operations, even in the event of complete site outages. The No Single Point of Failure concept combined with synchronous mirroring option and automatic failover for dual site environments helps you to meet even the highest SLAs and Non-Stop operations and always access to your most important mission critical data.

Multi-Platform Support

  • ETERNUS CS8000 is the worldwide only VTL which allows connectivity to all relevant platforms, e.g. IBM z/OS®, IBM i5/OS®, Linux®/UNIX®, BS2000/OSD and Microsoft® x/86 – even shared. The system might be logically and flexibly separated between different platforms, applications, customers etc. This enables you to benefit from the highest level of consolidation.

Highest level of Scalability and investment protection

  • ETERNUS CS8000 can scale-as-you-grow flexibly in both performance and capacity - up to market leading heights. Deferred investments, step-wise consolidation, leveraging saving potentials by migration to latest technologies over time helps you to achieve a fast ROI and to protect your initial investments.
