1. New Data Center at BNL– Status Update HEPIX – CERN May 6, 2008 Tony Chan - BNL

2. Background RACF (RHIC/ATLAS Computing Facility) provides support for RHIC experiments and ATLAS RACF (RHIC/ATLAS Computing Facility) provides support for RHIC experiments and ATLAS Rapid growth in the past few years caused space, power and cooling shortages Rapid growth in the past few years caused space, power and cooling shortages Steep capacity ramp-up for ATLAS cannot be accommodated with current facility resources Steep capacity ramp-up for ATLAS cannot be accommodated with current facility resources Phased increase in facility infrastructure over many years Phased increase in facility infrastructure over many years

19. Summary The growth of the RACF in the past few years exposed severe infrastructure problems The growth of the RACF in the past few years exposed severe infrastructure problems Learned some important lessons (maximize use of existing space, better planning, etc) Learned some important lessons (maximize use of existing space, better planning, etc) Renovated space and additional power available in October 2008 – some breathing room Renovated space and additional power available in October 2008 – some breathing room New data center dedicated to RACF will be available in summer 2009 New data center dedicated to RACF will be available in summer 2009 New facility in long-range plan after 2015 New facility in long-range plan after 2015
