5. RuTier2 to the LCG start 2006:  FASI budget for equipment about 1.7 MEuro (not confirmed yet) about 30% smaller than requested;  JINR budget is not known yet;  plus additional money from internal sources of participating institutes (SINP MSU, RRC KI, PNPI, ITEP and IHEP, …) The equipment status for this year: the budget to be fixed/known to July-August 2006; to install in autumn 2006, available for experiments in the end of 2006 already clear that: no tapes, 1500 KSI2K CPU and 600 TB Disk (25% reduction) could be further reduction … 2007-2011: budget planning – about 2 MEuro per year for equipment Time milestones for the equipment installation: Understanding to the spring 2006: 200520062007 (3-5%)40%60%

6. RuTier2 in the World-Wide Grid RuTier2 Computing Facilities is operated by Russian Data-Intensive Grid (RDIG), we are creating as Russian segment of the European grid infrastructure EGEE http://www.egee-rdig.ru RuTier2 sites (institutes) are RDIG-EGEE Resource Centers Basic grid services are provided by RRC KI, SINP MSU, and JINR Operational functions are provided by IHEP, ITEP, PNPI and JINR Regional Certificate Authority and security are supported by RRC KI User support (Call Center, link to GGUS in FZK) - ITEP RDIG budget (about 1 MEuro per year) 2005-2006: by EU FP6 EGEE (EGEE-II) ~ 50% by FASI (two grid technological projects) and by Rosatom ~ 50% 2007-2008: EGEE-II Contract has been signed recently by EU FP6 FASI and Rosatom budget is under constructive approval Final draft of WLCG MoU:

8. International Connectivity International connectivity for Russian science are based today on 622 Mbps link to GEANT2 (2.5 Gbps from autumn 2006) Moscow (RASNet) – Frankfurt (GEANT2) 5~10~20 Mbyte/s achieved for LCG data transfer in first experiments within Service Challenge activity (SINP, JINR, ITEP) Another channel, within link 2.5 Gigabit/s Moscow - St- Perersburg – Stockholm operated by RUNNet and then to Amsterdam (SURFNet) operated by RBNet (GLORIAD) is available for us too. Now – to test these links for SC4 needs (started with Kors Bos) Connectivity with USA, China, Japan and Korea LCG partners through the GLORIAD: 622 Mbps Chicago-Amsterdam-St-Petersburg-Moscow 155 Mbps Moscow – Novosibirsk – Khabarovsk – Beijing Plans: 2006 622 Mbps – 1 Gbps, 2007 1-2.5-10 Gbps
