The UK Tier-1/A Centre
The centre provides large-scale computing facilities for UK Particle Physics experiments. In January 2005 these consisted of approximately:
- 1000 Intel CPUs (1.4Ghz-2.8GHz) running Linux
- 140TB of available disk space
- Tape storage using a StorageTek robot system (total capacity up to 1.2 PB)
Views of some of the newer resources can be seen here.
