Challenges - Data volume
- ATLAS will collect 1 Pbyte of data per year
How to visualize this amount of data?
- Take a CD-ROM (~0.5Gbyte) 1.5 mm thick
Note: 1 CD-ROM holds the full Encyclopaedia Britannica
- Stack 2 million CD-ROMS for 1 Pbyte --> 3km
- ... on the other hand it is only five times the 200 Tbyte tape robot to be installed at CERN
