11. Service Data Challenge Meeting, Karlsruhe, Dec 2, 2004 Forschungszentrum Karlsruhe in der Helmholtz-Gemeinschaft GridKa planning for the next year increase CPU/ disk/ tape capacities by ~30% 10 Gbit/s Internet into production performance tests & optimization of SAN storage access testing S-ATA in production dCache connection to tapes in production Planning for expansion 2006-2008 ! Tier-0/1 Service Challenges gLite (at least) in pre-production service

12. Service Data Challenge Meeting, Karlsruhe, Dec 2, 2004 Forschungszentrum Karlsruhe in der Helmholtz-Gemeinschaft Issues application software & middleware depends on OS (too ?) many different test and production services with different status - prototype service (testbed) with SL & gLite - pre-production service with SL on WN & LCG-2.2.0 - service challenge setup - implementing VOMS & accounting - production service with RH7.3 We are currently writing a migration plan to Scientific Linux & LCG-2.3.0 - its not easy without interrupting services - versions of exp. software & mw MUST become more flexible & interoperable in the future lets see gLite; might be better ?

13. Service Data Challenge Meeting, Karlsruhe, Dec 2, 2004 Forschungszentrum Karlsruhe in der Helmholtz-Gemeinschaft Issues II limited technical information for planning 2006-2008 - how many Tier-2s and what are their demands - data classes and data rates from applications (tape access!) wait for computing models in January04 limited manpower resources for increasing number of activities - applied for in 2005: 30 persons - funded in 2005:20 persons - avail. end of 2004:15 persons (+ 4 in GGUS)... for everything including implementation, testing & running the GridKa site for LCH and non-LHC
