10. Fermilab User Facility April 13, 1999US-CMS User facility Matthias Kasemann, FNAL10 Size of the Tier 1 Regional Center u The base for these estimates is a set of figures for CMS offline computing at CERN that was made available by CMS in mid-1998. u CPU (1 TIPS = 10 6 MIPS  25k SpecInt95) u in 2005: 3.6 TIPS u 2006 on:1.2 TIPS new + 1.2 TIPS replacement u Disk storage u in 2005:108 TB u 2006 on:40 TB new + 27 TB replacement u Serial storage u in 2005:1 robot + 0.4 PB u 2006 on:0.2 PB new + robot every 3 years

11. Fermilab User Facility April 13, 1999US-CMS User facility Matthias Kasemann, FNAL11 Hardware cost estimation u Costs de-escalated according to technology-cost development expectations. u Actual costs for CPU and disk are based on our Run II experience: u CPU: $3.5M/TIPS in 2003 (extrapolated from 1999) u disk: $26.90/GB in 2003 (extrapolated from 1999) u The cost reflect the use of expensive SMP machines for analysis in Run II. u Cost for serial storage also based on Run II u $1.1M per robot plus $0.5M/PB for media

12. Fermilab User Facility April 13, 1999US-CMS User facility Matthias Kasemann, FNAL12 Regional Center Schedule Implementation and Operation phase u To distribute cost over 2003, 2004 and 2005 and profit from price/performance evolution we plan to acquire 10% of disk and CPU in 2003, 30% in 2004, 60% in 2005. u Integrated capacity installed per year: 2003200420052006 CMS operation u CPU:0.41.443.64.8TIPS u disk:1143108148GB u tape:0.030.050.40.6PB u robots:10.33robots

14. Fermilab User Facility April 13, 1999US-CMS User facility Matthias Kasemann, FNAL14 Cost Summary u Total costs through 2005: u hardware:$10.6 M u networking in US:$2.1 M u licenses:$0.1 M / year u Operating phase u 2006 onward:$3.9 M hardware + 35 people u Note: u This hardware costs are based on what it is costing to serve 400-500 people in CDF and DØ under the assumption of exponential price/performance evolutions ($9.1M for CDF or D0). u Numbers are conservative (SMP-CPU,…)

15. Fermilab User Facility April 13, 1999US-CMS User facility Matthias Kasemann, FNAL15 US-CMS User Facility Summary u The User Facility has to provide US-CMS scientists with a competitive infrastructure to fully participate in the science program of CMS. u FNAL with the experience of Tevatron experiments is well suited to host the US-CMS major ‘Tier 1’ Regional Center. u Setup and support of the Regional Center will happen during 2003 - 2005. Initial hardware cost estimations (w.o. networking) are $10.6M + 35 FTE’s (by 2005). u Operations cost estimates are $2.7M/year for hardware (w.o. networking) and about 35 people. u Networking cost will be substantial.
