- Xml based
- Node=manageable unit and needs to be autonomous (everything it needs stored locally)
- Principles:configuration via one Node install and config reproducible
- Success story: LSF upgrade from single tool, config info through one interface and stored centrally. 2.4 to 5.1 on >1000 nodes in 15 minutes, kernel upgrade, security updates
- APT for RPM – Simplified Package Management
