Data protection challenges
Enterprise data is one of the most valuable assets in any company.
Some examples of data requiring backup are databases, customer
information or logistics data.
Today’s IT managers are confronted with enormous data growth.
About 75 percent of the data in any company is backup data. This
underlines the importance of the backup environment when searching for ways to optimize IT costs. As data volumes continue to grow
at a breathtaking pace, backup windows quickly reach their limits
and can become serious storage bottlenecks. That’s why a very important aspect of any backup infrastructure is optimal utilization of
the underlying resources.
The growing importance of data in business processes requires higher
protection levels that include things like disaster recovery solutions.
And secure long-term storage is demanded for some types of data,
especially when it comes to compliance regulations. The problem for
storage administrators is to maintain service levels, for example, for
data availability, disaster recovery, compliance and long-term storage
while keeping costs down.
Business cost pressure means that IT managers are constantly coping
with shrinking IT budgets. They are required to do more than ever
before, but with fewer resources. IT infrastructure and administration
budgets are always under scrutiny.
Sooner or later the IT department will face technological challenges
which must be addressed in order to fulfill requirements in providing
sufficient data protection, especially when budgets are limited.
Generally speaking, IT departments are usually cost centers rather
than profit centers in most business enterprises. Data backup and
archiving are defined by a company’s business needs, regardless of
balance sheet totals.
Different kinds of backup and archiving target systems, like tape
libraries, virtual tape libraries (VTL) and deduplication appliances,
can be deployed in data protection environments. Each of them
comes with individual strengths and weaknesses – but they are still
effective tools for safeguarding data. Quite often various target
systems are used simultaneously, but this has a number of disadvantages:
■ imited capacity and performance scalability in many appliances
is a critical issue.
■ ultiple storage systems are deployed, resulting in diverse isolated
■ anagement of the entire environment becomes extremely inM
flexible and requires manual intervention, not to mention the
skyrocketing costs of maintenance.
And the larger the IT department, the more complex the data protection environment. This complexity poses three significant challenges to effective data protection – namely rapid data growth, cost
pressure and SLA management.
Enterprises need to cope with backup windows, and running backups
is necessary in order to be in a position to recover data. No more,
no less. The key is how to make this more efficient – in a businesscentric way.
Unified Data Protection
The concept that differs from others
“Business-centric” means allocating storage resources for data protection according to business priorities: To fulfill the right levels in
terms of speed, capacity and data availability, and at the same time
to minimize investments and the total cost of ownership.
Successful and proven platform
The Fujitsu appliance is used around the world by the largest data
centers in data-intensive segments such as financial services, insurance, telecommunications, public administration, industry and IT
The elements for the most efficient data protection solution are:
■ Your preferred backup and archive software
■ Fujitsu Storage ETERNUS CS8000 Series
ETERNUS CS8000 is a platform designed on the basis of real-world
best practices. Its ongoing development has continued for many years
in collaboration with a well-established user group. That translates
into optimal support and keen awareness of the demands arising
from daily system use.
Fujitsu Storage ETERNUS CS8000 Series
The ETERNUS CS8000 unified data protection appliance provides a
most economical way to overcome the challenges in complex backup and archiving environments. Unlike other data protection appliances, ETERNUS CS8000 does much more than just provide storage
capacity. It consolidates the backup and archiving infrastructures of
open systems and mainframes. Thanks to the uniform management
of disks, deduplicated disks and tapes, flexible service levels governing
capacity, speed and cost are possible. And support of a cloud gateway
functionality makes ETERNUS CS8000 an ideal and future-proof
solution for a unified and optimized data protection infrastructure.
ETERNUS CS8000 virtualizes target systems and creates one logical
data protection platform. In so doing it provides more flexibility and
higher service levels at lower cost.
“ he ETERNUS CS concept completely convinced
us. In particular, the high level of scalability and
openness for all systems at both the frontend
and backend represent major advantages.”
Oliver Heuser, Platform Manager for Database and Storage, Postbank Systems AG
“ don’t know of any other solution that could proI
vide total backup and restore functionality for both
our mainframe and open system worlds.”
Bernd Bohne, Department Head Central Systems Technology,
Unified Data Protection Platform
Target System Virtualization
One solution for backup and archiving
Huge consolidation potential
ETERNUS CS8000 is the solution for consolidating complex and
heterogeneous data protection environments on a large scale. To
provide full consolidation, ETERNUS CS8000 can connect to all
well-known platforms, including open systems and mainframes. All
physical and virtual server environments can use the same backup
and archiving infrastructure.
Second-tier file storage
By moving old or non-critical data from production storage to secondtier file storage, administrators can increase the usable storage capacity
on the systems which run their mission-critical data. The reduction
of data volume stored in productive environments results in faster
backup and recovery. The data stored in second-tier file storage can
then be managed with more ease at a different data protection
From the backup software perspective, the ETERNUS CS8000 appliance
appears as a virtual tape library. The unified data protection platform
provides intelligent management of the media mix – known as
automated Information Lifecycle Management (ILM). It combines
the strengths of disk and tape with rule-based management, providing seamless and automated backup-to-disk-to-tape (B2D2T)
To benefit from this “data offloading” to second-tier storage targets,
care must be taken not to underestimate the infrastructure complexity that can result from bringing additional “storage islands” into
the IT infrastructure. Thus, in addition to serving as a backup target,
ETERNUS CS8000 provides optional standardized NAS interfaces with
NFS and CIFS protocols. The result is a scale-out NAS system which
can act as a second-tier storage target supporting billions of files.
ETERNUS CS8000 is also the only solution on the market which supports complete parallel operation of B2D2T, as well as backup to deduplicated disks, with the same appliance. Data can be easily stored
on the appropriate media to fulfill the required service level.
Archiving and long-term storage
Thanks to the optional NAS interfaces, ETERNUS CS8000 can be also
be used as an archive and long-term storage system. The support of
billions of files results in an enormous storage pool.
■ onsolidation with ETERNUS CS8000 delivers tremendous cost
savings in complex environments.
■ ighter workloads for IT administrators.
■ etter infrastructure utilization means lower costs.
Furthermore, direct integration with tape enhances the unified data
protection appliance for Hierarchical Storage Management (HSM)
to automatically save data to disk and tape, according to defined
migration policies and retention periods.
■ rchiving and second-tier file storage frees up resources in the
production environment and in the backup infrastructure.
■ ackup and recovery are much easier.
■ SM leverages the advantages of tape, which is the most reliable
and cost-effective media for long-term storage.
“ he ETERNUS CS data protection appliance from
Fujitsu gives us investment protection in terms
of data backup scalability, plus freedom of
choice when it comes to deploying server platforms such as mainframe and Linux systems.
By consolidating our infrastructure, we can vary
workloads and capacities as needed.”
Urs Haeringer, Director of Technology Management, Helsana Insurance AG
Enable legally compliant archiving
ETERNUS CS8000 is a platform which allows for legally compliant archiving. It ensures that the files are stored in a secure way, making
them revision-proof for a defined retention period to fulfill specific
requirements like compliance regulations. This is possible with the
integrated WORM functionality.
Furthermore, Fujitsu has developed a solution for trusted long-term
storage which ensures evidential value preservation and the physical
preservation of the data itself:
■ ETERNUS CS8000 takes care of the physical preservation of the
data. It is a storage solution which fulfills all the requirements of
storing archive data, including files with compliance demands.
■ Fujitsu SecDocs archiving middleware takes care of evidential value
preservation. It is an enterprise solution for long-term preservation
and legally secure archiving of electronic documents. The middleware combines a reliable archiving process for large numbers of
documents with the creation and preservation of evidential value –
flexible, cost-efficient and applicable across all industries. SecDocs
does not replace the archive software, but rather enriches it with
functions for evidential value preservation.
IT archives are easier to handle with the combination of SecDocs and
ETERNUS CS8000. Existing archive applications as well as storage
systems can be leveraged and enriched with functions for evidential
Investment protection for the entire data protection environment
ETERNUS CS8000 is a unified data protection platform for all applications and the complete physical and virtual server environment. It
integrates backup, archiving, compliant archiving and second-tier
file storage, while supporting the complete consolidation of heterogeneous environments. Infrastructures can be consolidated, the
resources are leveraged and the costs are dramatically reduced.
Changes in the infrastructure can be managed quite easily. The connectivity with all major open system and mainframe platforms allows
for easy adaptation to changes in the production environment, not
to mention the support of major backup and archive software.
The management process for tape libraries is integrated with the ILM
and HMS functionality. The tape libraries are decoupled from the
backup and archive software, so that it is very easy to make changes
in the physical tape infrastructure – for example, when introducing a
new generation of tape libraries or tape drives. ETERNUS CS8000 takes
care of data migration, from the old tape library to the new one.
■ TERNUS CS8000 adds flexibility to data protection landscapes
while reducing complexity at the same time.
■ asy adaptation to future requirements without the need to invest
in incompatible system architectures.
■ Assurance that legal directives are fulfilled, including prevention
of data loss that could eventually result in serious penalties.
■ KPMG AG has confirmed that ETERNUS CS enables storage and
retrieval of electronic documents based on Generally Accepted
German Accounting Principles.
Flexible service levels
Aligning capacity, speed and costs
Modular scale-out architecture
The basis of the ETERNUS CS8000 solution is a modular grid architecture. Independent building blocks provide a genuine scale-out platform. The main elements are:
■ ront-end processor nodes (which manage the data stream between
servers and ETERNUS CS8000),
■ nternal RAID systems (providing the disk storage)
■ ack-end processor nodes (which manage the data stream between
ETERNUS CS8000 and additional target systems)
Put simply, the basic backup-to-disk-to-tape workflow is as follows:
Data from the backup software is sent to ETERNUS CS8000 and received by the front-end processor node. It is stored in the internal
RAID storage. The data can then be copied to a tape library via the
back-end processing node.
Front-end processor nodes
■ TL interface
■ ackup data repository (compressed or dedupliB
■ AS/file interface
■ rchive/file repository
■ quipped with SAS / Nearline SAS / SAS SED (Self
Encrypting Disk) / Nearline SAS SED
■ ptional for integration of tape libraries at the
■ nd support for the cloud gateway functionality
Back-end processor nodes
ETERNUS CS8000 comes with great flexibility to grow, starting from
7 TB up to 15,000 TB (=15 petabytes!) of physical disk capacity. All
data received via the VTL interface is automatically compressed before being saved to disk. This reduces the amount of required storage
space without any loss in performance. The disk storage can act as
the final target or as a cache for data which should be copied to tape.
Physical tape libraries can be connected and data can be automatically moved to tape. The support of several tape libraries in parallel
increases the amount of data ETERNUS CS8000 is able to handle –
up to the exabyte range – and offers the best price/capacity ratio for
As an alternative to the backup-to-disk-to-tape process, ETERNUS
CS8000 can also act as a final backup-to-disk storage target with de6
duplication. ETERNUS CS8000 can be enhanced by including the deduplication functionality for this purpose. Physical disk capacity – from
1 terabyte up to a maximum of 4.8 petabytes (before deduplication) –
can be used as deduplication storage.
Another option which may play a more important role in the future
is storing backup data in the cloud. The ETERNUS CS8000 concept is
perfect for caching the data dedicated for the cloud. As a future enhancement, ETERNUS CS8000 will be capable of using the cloud as
an additional target via a cloud gateway.
■ he great scalability of capacity makes coping with exponential
growth rates much easier.
■ ntegrated data reduction technologies and tape integration reduce
the cost of storage capacity.
“ hat impressed me was that ETERNUS CS makes
it possible to achieve uniform improvement in
data backup and recovery on physical tape
across our entire server environment.”
Curt Borschel, Manager Enterprise Storage Management, Lufthansa Systems
The great advantage of the ETERNUS CS8000 scale-out architecture
compared to scale-up architectures is the scalable system performance, which can be increased whenever necessary by adding frontend processor nodes. This decouples investments in performance
from the storage capacity. Enterprises only need to invest in what is
required: capacity or performance.
Optimized media mix for flexible SLAs
To provide flexible SLAs, ETERNUS CS8000 combines the strengths
of disks, deduplicated disks and tapes with rule-based automated
management. Disk capacity can be flexibly utilized as high performance disk storage, as a performance booster for tape storage and
as a final disk storage repository with deduplication. Performance
will stay in balance with the media cost.
ETERNUS CS8000 provides the highest levels of performance, in larger
configurations up to 150 TB/h for backup-to-disk. Due to the support
of more than a thousand virtual tape drives, many backup processes
can be carried out in parallel.

■ est price/capacity ratio
■ ifetime: 30 years
■ igh streaming performance
■ ovable (vaulting)
The deduplication functionality also benefits from the scale-out
infrastructure. The deduplication workload can be parallelized between several front-end processor nodes, which will speed up the
Investment protection of the appliance
In addition to safeguarding the investment made in the data protection environment, ETERNUS CS8000 provides investment protection
for the data protection appliance itself. A project may start with a
small configuration which can grow step-by-step. The modular scaleout architecture, with its flexibility in performance and capacity,
combined with comprehensive connectivity, enables customers to
adapt to changing requirements. Flexibility and consolidation mean
that the backup infrastructure for maximum utilization is directly
aligned with business needs. Investment protection is ensured, even
when business requirements change, and up-front investments can

Comprehensive data availability
Robustness and disaster recovery
■ ighly available appliance:
To ensure the availability of the consolidated storage pool of
ETERNUS CS8000, all components are redundant. The architectures
of traditional deduplication appliances have single points of
failure. The ETERNUS CS8000 architecture is different – there is no
such limitation, and even the deduplication storage repository is
■ isaster resiliency:
Not only are components redundant: With backup-to-disk-to-tape,
ETERNUS CS8000 can keep multiple copies of the data by writing
data to local and remote tape libraries, and by asynchronous replication within a range of thousands of kilometers. This provides
an easy way to introduce disaster resiliency with a remote copy.
■ utomated continuation:
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 ETERNUS CS8000 infrastructure is
thereby extended to a second site. The backup software still sees
one logical setup, without even being aware of the geographical
location. Data can be written to or read from both sites. The result
is a system with no single point of failure, which continues to run
even after a complete site failure.
The ETERNUS CS8000 is the only system worldwide that can do this!

■ lexible 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. Human administrator errors are prevented, and
there is almost zero management needed after setup, and yet different service levels for different applications will be supported – at
the lowest possible cost per service.
■ utomated copy management prevents human administrator errors.
■ perational risk is minimized.
■ he backup network is not burdened with the workload.
■ he availability level of data can be aligned with its impact on
“ ujitsu’s ETERNUS CS solution perfectly meets our
high-availability requirements. And it alone supports all backups of the entire sever landscape.”
Alfonso Yeregui, Head of System Operations, Laboral Kutxa
■ Management of the tape infrastructure:
The management of tape media can be complex and time-consuming. Therefore, ETERNUS CS8000 takes over the management
of all the target systems and provides a highly available virtualized
tape robot. The redundant architecture enables reception of the
backup data, even if a component should fail. If the back-endwrite process to the physical tape fails, then the data will automatically be directed to another target system to ensure that the
data is safe.
■ Tape reorganization:
One purpose of the reorganization function of ETERNUS CS8000 is to
effectively utilize the tape capacity available. Furthermore, regular
reorganization of tape media (that have not been accessed for a
long time) refreshes the magnetization of the tapes and prevents
age-related loss of the magnetization. This can be initiated by the
administrator, or be defined as a regularly occurring automatic
process. It can automatically make quality checks of duplicate copies.
If an error occurs on the tape media, the self-healing functionality
recovers the inaccessible information from the other copy. This
ensures the availability of data even over the very long-term.
If a data copy is corrupt or not available for some reason, then the
recall request of the backup software is automatically redirected to
the second copy. Of course, this presupposes that the data was at
least written in a dual-copy service level. The copy will be provided
and the job for the backup software is done. An automated selfhealing mechanism is initiated by ETERNUS CS8000 that will recover
the failed copy. Thus the level of redundancy is restored.
Step 1: Redirect
Step 2: Self-healing
■ Automation of tape processes reduces operational workload.
■ ETERNUS CS8000 in combination with tape provides the most
reliable solution for short-term, mid-term and long-term storage.
■ he defined service level is guaranteed through an always available
self-healing backup copy.
