25 Michal Turala Warszawa, 25 February In response to the LCG MoU draft document and using data of the PASTA report the plans for Polish Tier2 infrastructure have been prepared – they are summarized in the Table Polish LHC Tier2 - future CPU (kSI2000) Disk, LHC (TBytes) Tape, LHC (TBytes) WAN (Mbits/s) Manpower (FTE) It is planned that in the next few years the LCG resources will grow incrementally mainly due to local investments. A step is expected around 2007, when the matter of LHC computing fundings should be finally resolved. from the report to LCG GDB, 2004
