16 Volker Guelzow | PRC | | Page 16 The DESY GridLab: Idea: > DESY Grid more than just a production site > Have dedicated machines to develop and test new products and components … representative for and integrated into production environment > Reusing old WNs from Grid, temporarily borrowing WNs from production Grid > Purchasing some dedicated HW (storage) > Contacts: D. Ozerov, Y. Kemp Activities: > Taking part in the WLCG storage technology demonstrators: > NFS v4.1 (pNFS) with dCache.org > Benchmarking LHC applications on a dedicated setup: HEPIX, CHEP, EMI conference contributions > Together with external physicists > Platform for Cloud & virtualization testing in Grid context > Platform for DPHEP prototype > Platform for external students work > …

17 Volker Guelzow | PRC | | Page 17 NAF usage shares 2011 Wall Clock Lustre Space

18 Volker Guelzow | PRC | | Page 18 NAF usage by VO‘s

19 Volker Guelzow | PRC | | Page 19 NAF: Current open questions and discussions > Some requests from the user community  Increase stability and reliability of NAF AFS  Lustre management tools (group quotas, old-file-deletion, synchronization with dCache)  Interactive and graphical software stack on the NAF  Faster X-access (other protocols like NX)  Install CernVM-FS for experiment software (NAF&Grid)  Faster reaction and fixing of problems, better user information  … > NAF provider view:  Many of these requests make sense, and we think could be useful  Some requests very difficult: e.g. Lustre product has deficiencies and lacks features  Other requests have to be rejected because of lack of manpower and difficult to integrate into current NAF setup as targeted to a national community

Central Code Repositories Organization of developers meetings and workshops Services activities: Test infrastructure & performance (Grid-Lab) Quality Management Release Management Customer support : Tier I conferences, Network Activities : DESY : dCache operations (DOT) and Grid-Lab Germany : HGF, DGI, German Support Europe : EMI, NDGF, Swedish National Infrastructure Worldwide : WLCG, Open Science Grid, Open Grid Forum Main communities WLCG HERA Photon Science DESY) LOFAR (LOw Frequency ARray) : Amsterdam & Jülich Swedish academic storage e-infrastructure (SNIC)

DESY gets € over 3 years = 2 FTE plus a lot of traveling dCache is one of the 4 middle-wares (gLite, ARC, UNICORE, dCache) dCache.org provides the EMI data area leader (Patrick) EMI provides access to new communities EMI provides efforts for standards in dCache (more non HEP customers) dCache, People and Funding Contact : Patrick DESY dCache provides a stable collaboration, important for HEP and strategically interesting for DESY. dCache success attracted 3. party money.

31 Volker Guelzow | PRC | | Page 31 Summary > The DESY-Grid-Centre is one of the top centres in WLCG > The NAF is very helpfull and used nationwide > The NAF needs further (interactive) options > dCache is the major working horse for LHC datamanagement and DESY has the lead > LHCone is a great chance for changing computing models > DESY has take the leading role for LHCone in Germany > There is an open financing issue for the Universities Tier 2 after id 2012
