ATLAS holds 1,000,000 Gigabytes
Fri 12 Dec 2008
The UK's contribution to computing for the LHC reached an important milestone last month when disk storage dedicated to the ATLAS experiment at the Rutherford Appleton Laboratory (RAL) broke the petabyte barrier.
As of the 25th of November the UK's Tier 1 facility at RAL now has over 1,000 terabytes of disk storage available to ATLAS, one of the main four experiments at the LHC. Based in Oxfordshire, RAL has more than 2 petabytes on the Grid but this is a major achievement for the UK involvement in ATLAS.
It was just over six years ago that RAL received the first machines which would grow into the current Tier 1. This consisted of only 156 machines with a total of 4.7TB of storage, less than half a percent of the amount now available to ATLAS alone.
This news came a few days before GridPP switched off its final two Resource Brokers in favour of the Workload Management System. These two events reflect the increasing maturity of the UK Grid and its readiness to deal with the upcoming data deluge from the LHC.
