Preparing CERN Tier-0 data centres for LHC Run 3

Preparing CERN Tier-0 data centres for LHC Run 3

Since 2013 CERN’s local data centre combined with a colocation infrastructure at the Wigner data centre in Budapest [1] have been hosting the compute and storage capacity for Worldwide LHC Computing Grid (WLCG) [2] Tier-0. In this paper we will describe how we try to optimize and improve the operati...
