Storage: Alternate Futures
Acknowledgments: Thank You!!
Outline
The Surprise-free Storage Future
1 Gb RAM Chips
MAD at 50 Gbpsi
Disk vs Tape
System On A Chip
500 mips System On A Chip for 10$
Standard IO in 5 Years
Ubiquitous 10 GBps SANs in 5 years
Thin Client’s mean HUGE servers
Standard Storage Metrics
New Storage Metrics: Kaps, Maps, SCAN?

The Access Time Myth
Storage Ratios Changed
Data on Disk Can Move to RAM in 8 years
Outline
The (absurd?) consequences
The Absurd? Consequences
Storage Latency: How Far Away is the Data?
Consequences
Auto Manage Storage
The “Absurd” Disk
Extreme case: 1TB disk: Alternatives
Drives shrink (1.8”, 1”)
Prediction: 6-packs
Stripes, Mirrors, Parity (RAID 0,1, 5)
RAID 10 (strips of mirrors) Wins “wastes space, saves arms”
The Storage Rack Today
Storage Rack in 5 years?
It’s hard to archive a PetaByte It takes a LONG time to restore it.
Crazy Disk Ideas
The Disk Farm On a Card
Functionally Specialized Cards
It’s Already True of Printers Peripheral = CyberBrick
All Device Controllers will be Cray 1’s
With Tera Byte Interconnect and Super Computer Adapters
Implications
How Do They Talk to Each Other?
