1 THIS TEXT WILL NOT BE SHOWN DURING PRESENTATION! Design by Jon Angelo Gjetting Reproducability not allowed without explicit written consent from Jon Angelo Gjetting. The Nordic Distributed Tier-1 Presented at the GDB Meeting at CERN June 21 st 2005

2 Who? Denmark Finland Norway Sweden

3 The Nordic Tier-1 The Nordic Tier-1 will be distributed –amongst all countries –amongst centers within the individual countries However there will be only one –interface from the rest of the world –network connection to Europe

4 Distributed Tier-1 A distributed Tier one has been chosen because –None of the resources available will be exclusive to LCG –A high up-time is much easier to achieve with a distributed Tier-1

5 Standard Tier-1 design (highly simplified) SRM gridFTP

6 Nordic Tier-1 design (highly simplified) SRM gridFTP

7 DK N S Fin Storage Interface Distributed Tier-1 Design SRM

8 DK N S Fin SRM gridFTP Storage Interface Distributed Tier-1 Design Storage Access

9 DK N S Fin SRM gridFTP Compute Submit Job Interface Storage Interface Job Access Storage Access Distributed Tier-1 Design

10 Expected Resources (Early Numbers)

11 Expected Resources ATLAS

12 Expected Resources ALICE

13 Expected Resources CMS (very early numbers)

14 Status We are running ARC Early prototype in final design Some portions should be tested during SC3
