Talk Title:Efficient rec

overy of erasure-coded storage -- and -- erasure-coded cloud storage

Talk Abstract:

In the first half of the talk, I''ll talk about resu

lts I recently presented
at MSST (massive storage systems & techn

ologies) on techniques for recovery
of erasure-coded storage. The tech

niques I describe are complementary to
traditional RAID techniques (e.

g., parity declustering and distributed
sparing).

In the s

econd half of the talk, I''ll give a high-level, informal overview of
an eventually consistent, erasure-coded key-value storage system we have

been building.
 
The two halves of the talk are only
loosely related...
