    1617The CERN computer centre currently manages over 7000 machines providing the computational and storage power needed to handle the vast amount of data due to flow from experiments on the [http://www.cern.ch/LHC/ Large Hadron Collider] ([http://en.wikipedia.org/wiki/Large_Hadron_Collider wikipedia page]). An overview of the CERN deployment can be found in the 2005 article [http://cerncourier.com/cws/article/cnl/22404 ELFms at CERN].

    2122CNAF is the National Center of [http://www.infn.it/indexen.php INFN] (Italian National Institute for Nuclear Physics) for Research and Development activities in Information Technologies applied to High Energy physics. Since 2005, [http://www.cnaf.infn.it/main/index.php/en/ CNAF] has been the Italian Tier-1 center for LHC experiments and a reference computing center for several other experiments. As of November 2008, it provides distributed access to about 7MSI2K of CPU power, 2.3 PB of disk and 3PB of tape space. CNAF system administrators uniformly manage more than 1000 nodes (most of them running the EGEE middleware) with Quattor.
