10. U B 10 dCache – Castor2 Migration Castor Data Timeline 20 June. At the UB meeting it was agreed that 6 month notice be given for dCache termination. 26 November. Proposal to terminate dCache by end of May. Going to be Tight…. LHCb – all disk data migrated and 60% of tape data. ATLAS – disk and tape migration ongoing (?). On 20 Feb, 12TB trimmed from CMS allocation to help ATLAS migration (270TB allocation+20TB). ALICE – Updated request received 25 Jan. Allocated one server on 6 February. Need xrootD plug-in. MINOS – agreed 3 month period from date of working Castor instance.

11. U B 11 User Support Posts - GridPP3 Janusz Martnyiak (Imperial) = 50% FTE Ex-portal post. Technical assistance with Grid related software, interfacing experiments to middleware, development of tools, etc. First priority is to help smaller non-LHC experiments to get established on the Grid. LHC projects, generic PP tools (eg. Ganga) and KE with non-HEP VOs also possible work areas. Experiments bid through UB chair for support. MICE (Ganga and LFC) already approved and some SuperNemo work (LFC). Stephen Burke (RAL) = 50% FTE Documentation post. Focussed on immediate and short-term issues. For example, helping answer technical enquiries (outside ticket system), trouble-shooting user/VO problems, locating suitable documentation, etc.
