Summary
Disks will become supercomputers so
- Lots of computing to optimize the arm
- Can put app close to the data (better modularity, locality)
- Storage appliances (self-organizing)
The arm/capacity tradeoff: “waste” space to save access.
- Compression (saves bandwidth)
- Mirrors
- Online backup/restore
- Online archive (vault to other drives or geoplex if possible)
Not disks replace tapes: Storage appliances replace tapes.
Self-organizing storage servers (file systems) (prototypes of this software exist)
