active archive: data protection for the modern data center
DESCRIPTION
Backup has long been thought of as the key technology for data protection (DP). In today’s modern data centers, the fastest moving and most fundamental changes in DP are in Archive, as data is growing at a 60+% annual rate. Case studies will illustrate how active archives are being utilized.TRANSCRIPT

• Up to 70% of capacity of every disk drive installed today is misused– 40% of data inert– 15% allocated but unused– 10% orphan data– 5% contraband data
• Disk storage accounts for between 33 and 70 cents of every dollar spent on IT hardware: trend accelerating

Explosive Data Growth
Sources: *International Data Corporation 2010
• Where does all the data go?
• 11 Exabytes of digital data created in all of human history through 1999
• By 2001, that doubles
• By 2011, 1610 EB! *

Active Archive
Active Archive provides affordable, online solution to access and store all this newly created data!
An archive that contains production data, no matter how old or infrequently accessed, that can still be retrieved online.
Achieving Efficiency with Active ArchiveNASA Ames Case Study
Achieving Efficiency with Active Archive
NASA Ames Case Study• Pain Points
– Downtime due to media issues– Maxed out data center floor space utilization
• Goals– Ensure media and data integrity– Better manage media within the library– Improve storage density and footprint– Have all data online, searchable and accessible

Achieving Efficiency with Active Archive
Results—NASA benefits greatly migrating to an Active Archive:
IBM’s High Performance Storage System (HPSS) and Spectra’s T950 (8 Frame)
– Extended file system capacity on tape
– Reclaimed 1400 sq. ft. of data center space
– Increased online archive capacity 12 PB to 32 PB
– Increased data storage reliability

Tape technologies are reliable…Reliability has increased 700% over the technology available a decade earlier
• Advances in the coating of tape film
• Read-after-write data verification
• Error correction codes
• Drive technology features simplified tape paths and servo tracking systems

• Spectra libraries today have the intelligence to proactively alert if a media, drive or hardware issues are developing
• Gone are the days of not knowing if…– A tape has been used beyond any manufacturer
thresholds– There has been environmental damage to media– Failures are drive or media related– Data is on the tape media

Spectra storage offers high energy efficiency
Tape Library Disk System
Clipper Group Study, “Tape and Disk Costs” - Starting with 125 TB of data - Assuming 14.5 cents per kW/Hr increasing by 10% per year
Spectra’s libraries offer the greatest density
Reclaim space: 44 – 218%Low density disk array
Same capacity, smaller footprint

Spectra’s Tape Libraries are Fast…
* Based on benchmarked data; assumes 2:1 data compression* Based on 120 LTO-5 Drives* *Times vary based on library and tape drive in use
…really fast!
Write to tape: 121 TB/hr*
Access from tape: 65-75 seconds avg**
