Network-Embedded Programmable Storage and Its
Applications Randy Wang Princeton University
2
Experiments Network-Embedded Programmable Storage

• Active capsules that manipulate embedded
  storage
• Relationship with active nets
• Stem cells vs. blood vessels
• Make embedded storage as accessible as network
  resources
• Decouple intelligence from infrastructure

3
An Application A Meta Distributed File System

• More complex world than LAN vs. WAN
• What is a meta file system?
• A common framework, with
• Customizable STONE components
• For different topologies and different workloads
• Possibly with a STONE compiler
• Other applications P2P-rsync, crawler, etc.

Party Lines

• Tackling persistent storage is the next logical
  step for active nets
• Network and storage resources complement each
  other
• Network-embedded programmable storage
• Application-driven research
• Rapid deployment of new applications
• Sophisticated customization of a single
  application

SkunkNet A Mobile Storage Network

• Ad hoc file system
• Routing layer route from any device to any other
  device
• Storage layer track which device has what data
• Composition of the two layers route to the best
  replica

6
Requirements

• Minimum
• A non-root account, access to a raw disk
  partition
• Minimum
• Vital stats, like pathchar
• Root

7
Wish List (Two Interfaces)

• Per-node OS
• Global OS
• Resource container, code injection, persistent
  storage management, connectivity, location
  service, lock service

8
What we have done preliminary work on

• Per-node OS
• Global OS
• Resource container, code injection, persistent
  storage management, connectivity, location
  service, lock service

9
What we continue to improve on

• Per-node OS
• Global OS
• Resource container, code injection, persistent
  storage management, connectivity, location
  service, lock service
