Most mainframe shops use tape for deep archive data with the hope that if I need to access it, you will be able to find the cartridge and it is still readable. Tape is also used for HSM migration and storing fixed content data once the frequency of access has decreased. Once moved to tape the value of this data diminishes because of the time it takes to access it. How does the value of the data change if you had near instantaneous access to the information? Is it a competitive advantage if I had years of data available for on-line applications, versus 90 days of data? How much personnel savings can I realize by having this data available on-line versus retrieving it via batch processing? Discussion points include:
Potential CPU cycle savings in HSM processing by eliminating ML1 data
How fast and consistent access to tape data can improve operations and save money
How to save money by reducing tier-1 storage capacity
