5. Business Problems
• Operational risk and compliance requires more
effective business continuity
• Business efficiency/resiliency is always an issue,
and IT is falling short
• Better control of Recovery Point Objective and
Recovery Time Objective
© 2007 Hitachi Data Systems 5

6. Customer Requirements
• Established leadership of storage as the platform
of choice to perform replication
– “I use (server-based replication product) for some
of the data, but for my key applications I use
TrueCopy.”
– “Never lost data with my HDS gear and
TrueCopy”
• But…there are shortcomings with traditional
storage-based replication from all vendors
– “This stuff uses up all my cache”
– “I know replication is crucial, but I’d like to focus
system resources on my applications’
transactions”
– “Network bandwidth requirements are killing me”
– “Bitmap mode is painful”
– “Why can’t you guys come up with one tool for all
of my platforms?”

7. Customer Requirements (cont.)
• Historically storage arrays were not designed for
replication
• Replication has been successfully “retro-fitted” into
storage
– Best performance for demanding applications
– Proven legacy for data protection and disaster
recovery
– But as requirements have evolved over time, with
soaring amounts of replicated data, a better way is
needed
• Asynchronous remote copy takes of resources
away from the apps that run your business
– Cache, processors
– Bandwidth of replication network
• Complexity
– Multiple replication products and vendor
implementations
• Synchronous vs. asynchronous
– Async is becoming a key requirement for out-of-
region replication
© 2007 Hitachi Data Systems 7

8. Positioning
• Universal Replicator is a replication engine for
asynchronously replicating data hosted on or
attached to Universal Storage Platform, and is a
unique innovation over traditional replication
methods.
• It significantly reduces resource consumption, and
sets a new standard for data protection and
Application Optimized Storage
– … over any distance for business continuity or
improved IT operations
– …..without the need for redundant servers or
replication appliances
– …supporting both internal and all externally-
attached storage

9. Replication Technology: How Universal
Replicator fills the data loss gap
• Traditional data replication solutions have a RPO (data loss) gap that only HUR
can bridge

12. Key Benefits: Resource Optimization
• Single pane of glass heterogeneous replication
–Universal Replicator allows the replication of any
volume hosted on any Universal Storage Platform
supported vendor
• Lowers cache utilization compared to traditional
storage-based asynchronous replication through the
use of performance-optimized disk-based journaling
• Maximizes the use of bandwidth by adapting to the
available network resources and leveraging
performance-optimized disk journals at the same
time : better RPO control
Results in effective protection and significant
optimization of storage resources for critical
applications
© 2007 Hitachi Data Systems 12

13. Key Benefits:
Mitigation of Network Problems
• Typical issues include:
– Link failure
– Insufficient cache
– Insufficient bandwidth
• Maintains protection of data in case of
network problems by logging every change
in the journal and transmitting them later
(consistency maintained)
• Maintain a more current RPO during
unplanned outage situations

14. Key Benefits:
Enhanced Disaster Recovery Capabilities
• Builds on the data integrity heritage of TrueCopy
and leverages TrueCopy synchronous for
cascading 3 data center configurations
• Provides “no data loss” recovery at any distance
– Intelligently combines synchronous and
asynchronous replication with little impact on
application performance
– Can mitigate the need for destructive resync
processes
– Offers 4x4 capabilities for scalability and
performance
• Improves disaster recovery capabilities by
allowing for advanced 3 data center
configurations
– Cascading
– Multi-target
– No complex scripting required

15. Technical Highlights
• Key Technology:
– Written data is chronologically reflected to the secondary site
via journal volumes
– The journal supports consistency across multiple volumes.
– The journal is copied by the remote system
– Sorting by time stamp, sequence number
Journal data is stored in

16. The Importance of Three Data Center (3DC)
• Universal Replicator enables advanced 3DC,
but why should you care?
– Regional disasters
– Regulatory compliance
– No data loss over any distance
© 2007 Hitachi Data Systems 16

17. Technical Highlights
Please contact HDS for detailed features availability
• Cascading 3DC
– “No data loss” solution for long distance Disaster Recovery
– The Intermediate site may or may not be a processing facility
– When the production site fails, data copied by TC Sync is available in the
Intermediate site.
– A server at the Intermediate site is not necessary for the replication process
– Mitigates the risk of sidefile punctures
– It saves physical disk space as compared with previous 3DC solution (no
mirror needed in the intermediate site)

25. Complementary Products
• ShadowImage
– Natural “partner”
– Both products enhance each other for advanced data protection solutions
– Look for AtTime Split capabilities in the near future
• True Copy Synchronous
– Perfect combination with Universal Replicator for 3 data center configurations
– Truly allows “no data loss” solution over any distance
• TrueCopy Async
– Ideally, customers running two Universal Storage Platforms should use Universal
Replicator, not TrueCopy/A
– However, still is the product of choice for other platform combinations (9900, 9900V and
TagmaStore stand alone)
• Business Continuity Manager and Replication Monitor
– Limit or eliminate complex scripting
– Perfect combination
– Required for Universal Replicator on mainframe platforms
– For Open Systems: Replication Monitor
• Resource Manager; Device Manager
