Increased Computing Demand
Changing Cost Dynamics
Data Center Lifecycle Mismatch
US commercial electrical costs increased by 10 percent from 2005-06. 2- EPA Monthly Forecast, 2007
Data centers have doubled their energy use in the past five years.4 - Koomey, February 2007
Per square foot, annual data center energy costs are 10 to 30 times more than those of a typical office building. 1 - William Tschudi, March 2006
“Twenty-nine percent of clients identified data center capability affected server purchases ”- Ziff Davis
“Eighty-six percent of data centers were built before 2001”3
Over 160B Gigabytes of data created in 2006. Number is expected to grow 6X by 2010 – IDC, The Expanding Digital Universe, March 2007
Data Centers at a Tipping Point: Unsustainable Growth

Power issues in the data center are putting business growth at risk Data centers maxing out on power (and space)
Increasing densities of servers and storageare overloading cooling infrastructure
High energy costs are squeezing budgets
Regulatory and environmental pressures are growing
Near-term Challenges Storage is growing at 30-70% per year
An estimated 27% of data center power is used for storage
A rack of storage uses 2-10x the power compared with just a few years ago

Tape Data Protection Requirements Protect tape data in transit from the primary data center to a secondary
data center or business continuance site Protect tape data generated by mainframe as well as open systems
And use the same management infrastructure
Protect tape data in transit to a business partner, but allow the business partner access once the data has arrived
High Performance with no impact on backup windows Compliance with data protection laws

Chart source: IBM
The LTO Gen 4 standard differs from the TS1120 implementation of tape drive based encryption
Unlike the TS1120 tape drive, the LTO Gen 4 specification does not support encrypted (wrapped) key storage on the LTO cartridge
Key identifier is stored on the cartridges Associated Cartridge Data Keys stored in a Key store
LTO Gen 4 supports Application Managed Encryption via SCSI T10 commands This is the standards-based implementation that will provide for cartridge interchange between
drive vendors Requires Application ISVs to enable AME functions
– TSM available at GA– Other ISV’s considering
LTO Gen 4 does support external key management and out of band key delivery With appropriate modifications, encryption appliance suppliers or third party software may
support LTO Gen 4 encryption IBM’s approach is to enhance the EKM to support transparent LTO Gen 4 encryption
