Motivation
Data-intensive network-based services are becoming the most important application for high-end computing
But servers for them are too hard to manage!
We need single-purpose, introspective storage appliances
- single-purpose: customized for one application
- introspective: self-monitoring and adaptive
- with respect to component failures, addition of new hardware resources, load imbalance, workload changes, ...
But introspective systems are hard to build!
