Both Glasgow and Durham had planned and unplanned power shutdowns this quarter, which impact on downtime and SFTs

Under the “Promised – integrated kSI2K hours until this quarter” an estimate is provided of what the Tier-2 would have expected to provide to this quarter on the basis of planned installations. “Static kSI2K” shows what would currently be expected if all purchases planned to this quarter had been made and implemented. The actual columns show what has been delivered.

Also ahead in T1-T2 and T2-T2 FTS testing Poster accepted at CHEP NFS is limiting performance of both dCache and DPM. GlasgowLed UK in FTS transfer testing Led in testing of new DPM releases and utilities Developed FTS transfer test tools DPM/Dcache incompatibility led to problems in FTS testing Also: All sites promptly moved to authenticated RGMA connectors

12 2005 Q4Quarterly report: ScotGrid Tier-2 risks General risks Unclear about support cost implications of VO boxes Similarly about SC4 rolling upgrade schedule. Mitigating actions Trying to keep informed about developments. No real mitigation in place. Institute specific risks Glasgow: Warranties end in Feb-06 but procurement will not be until Summer Mitigating actions
