20. 20 Request for RDMS CMS T2s upgrade CMS request to upgrade by Jan. 2010: Total disk space – up to 1300TB Total CPU - up 4500kSI2K (~1800 job slots) First priority tasks: - Complete T1 T2 link certification for INR, IHEP, PNPI - Improve stability of operation (“availability” & “readiness”) - Full test of MC prod and analysis jobs running in parallel - Increase disk space at each of T2 up to 150 TB - Increase number of CMS job slots at each of T2 up to 200

21. 21 Summary ITEP, JINR, SINP and UA_KIPT- in a stable state RRC_KI – all sw required is installed, the links are certified but not in a stable state INR – not all the links required are certified – to be accomplished in a month or earlier PNPI – now installed 1 Gbs external channel; certification of link is in process IHEP – now installed 1 Gbs external channel; certification of link is in process ITEP, JINR and SINP support group space for MUON, JetMET/HCAL, HI and Exotica – thus the main efforts were applied to certify links to/from these institutes
