1. Dr Tim Smith CERN/IT For the visit of the Alliance of German Science Organizations

2. [Oct 2013] - 2 As Designed: W. LHC Computing Grid Distributed Data Management – Limited Network resources – Optimize / minimize movement – File placement logic – Deterministic / Static Site Data Management – HSMs – Transparent file access and movement Disk-Tape migration/recall

3. [Oct 2013] - 3 Research Data Infrastructure of today Distributed Data Management – Network: a resource to schedule – Dynamic data placement – Data transfer services – Expt replica management rules Site Data Management – Indep. technology choices – Decoupled tiers – Disk caches Managed by owners – Bulk 3 rd party migration to tertiary by owners AAA: any data, any time, any where

4. [Oct 2013] - 4 CERN Infrastructure of tomorrow Connectivity (100 Gbps) 2015: 15k servers, 300k VMs
