Increase productivity, efficiency and environmental savings by eliminating silos, preventing sprawl and reducing complexity by 50%. Using powerful consolidation systems, Hitachi Unified Storage or Hitachi NAS Platform, lets you consolidate existing file servers and NAS devices on to fewer nodes. You can perform the same or even more work with fewer devices and lower overhead, while reducing floor space and associated power and cooling costs. View this webcast to learn how to: Shrink your primary file data without disrupting performance. Increase productivity and utilization of available capacity. Defer additional storage purchases. Save on power, cooling and space costs. For more information please visit: http://www.hds.com/products/file-and-content/network-attached-storage/?WT.ac=us_inside_rm_htchunfds

8. DATA GROWTH CONTINUES UNABATED …
 Data growth: Doubling every 18 months
‒ Unstructured data (files) growing even faster
 Worldwide data creation exceeded 1
zettabyte in 2010 for the first time
 40% projected growth in global data
generated per year vs. 5% growth in global
IT spend *

9. … FAR LESS OF THE DATA IS UNIQUE
 75% duplicate data (IDC)
 80% (McKinsey Global Institute)

10. DATA DEDUPLICATION
 A storage-optimization technology
‒ Compression, SIS
 Reduces data by eliminating multiple copies of redundant
data and only keeping unique data
 First made popular for backup (secondary) devices, the
technology has been extended to support primary
storage
WHAT IS IT?

11. DATA DEDUPLICATION
 Challenge for companies today continues to be the cost and
associated cost of storage
Data storage
 Optimizing data in place, and reducing the on-disk footprint of data as
it is stored provides immediate savings in capacity and new disk
expenditures
 Drive down the cost per gigabyte − store more information in the
same gigabyte
Data management
 Reduces the volume of data that needs to be managed
 Reduces the frequency of backups

12. WHAT MARKET RESEARCH FIRMS ARE SAYING

13. WHAT MARKET RESEARCH FIRMS ARE SAYING
“… the percentage of deployments with must-
have primary dedupe ‘requirements’ will reach
anywhere from 5% (conservative) to 22%
(aggressive) by 2015”

14. WHAT HAPPENS DURING DEDUPLICATION
After Dedupe

Without Dedupe
54 4K Blocks Consumed
With Dedupe
Only 24 4K Blocks Consumed
30 4K Blocks (> 50%) Reclaimed

16. HITACHI NAS PLATFORM (HNAS)
DEDUPLICATION OVERVIEW
 Leverages HNAS unique hybrid core technology
‒ Indexing engine via CPU
‒ VLSI/FPGA technology
 SHA256 hash of a data block detect duplicate
 Up to 4 SHA calculators running in parallel
 Post-processing
‒ File system data is analyzed and processed for dedupe after it is
written to disk
‒ Not in data path – no risk of losing or being unable to access data
 Dedupe index is used to store and identify duplicate
blocks in a file system

17. IT’S ALL ABOUT POINTERS


 Maximum (in theory)
dedupe ratio is 239:1
‒ A HNAS block can be
shared up to 239 times
‒ For example, 478
duplicate blocks
dedupe down to 2
blocks
…

18. DEDUPE EFFICIENCY
 Typical enterprises 2:1 to 5:1 data reduction
 Higher in virtual environments
2:1 50% Savings
5:1 80% Savings
4:1 75% Savings
10:1 90% Savings

19. COMPETITIVE DIFFERENTIATION
 Extreme performance
‒ Up to 450MB/sec post-ingest throughput rate
 Dynamic quality of service (QoS)
‒ Avoid impacting application I/O
‒ Less degradation on I/O Performance
 Simple to use
‒ Not a hardware appliance
‒ Little to no administration required

20. QOS / THROTTLING MECHANISMS
 Automatic background
process
‒ No complex scheduling
process
‒ 24/7 operation
‒ No disruption to workflow
 QoS/auto throttling
‒ When the file serving load
passes beyond 50% (of
available IOPS or throughput
capacity), the engine throttles
back

21. RESULTS FROM A LEADING MANUFACTURER
REAL-WORLD RESULTS
“The current HNAS algorithm appears to be far better than
others (competitors) tested”
