1. Slide 1 Ubiquitous Storage Breakout Group Endeavour mini-retreat January, 2000

2. Slide 2 Crossovers OceanStore + Telegraph –OceanStore uses Telegraph storage manager to store data –State machine description of servers Telegraph + Ninja –Operator-based flows == Ninja paths? –Constructing paths: graphical vs. automatic path creation –Use Ninja to create a cluster for Telegraph Machine Learning –Operator reordering –Introspection for data placement –Multidimensional scaling and smart dust

3. Slide 3 Crossovers (cont.) Security –Security must be built in from the beginning to avoid toy systems –End-to-end vs. link-to-link security –HCI for key management –Denial of Service is a key issue –Physically secure devices (gadget) –Encrypted search ISTORE + Ninja + Telegraph –Fault-tolerant testbed

4. Slide 4 Proposal Cycles are free (Moore’s Law) Secure –Data secure –Protection against denial of service –Traffic analysis Ubiquitous Highly available Maintainable

5. Slide 5 Schedule OceanStore (end of summer) –Read-mostly prototype –Terabytes –Linux FS API –(Geographically?) Distributed Telegraph (May) –Initial version of storage manager (on Ninja?) –Initial q.p. based on Eddy (relational + internet svcs?) Ninja v3 (this semester) –Manageability –RPC –Demos: cluster jukebox over cellphone

6. Slide 6 Schedule (cont.) ISTORE –80-node prototype (spring break) –Availability, Maintainability, Evolutionary Growth benchmarks (<= May)
