FTS on SL4 at T1/2s

Is it needed by experiments, CMS only were present, nor was there any comment. Danielle, please provide a large level of caution with any upgrade at this time.

Availability Metrics

Correction of availability metrics due to incorrect setting of LFC write test to Critical

The Gridview team are recalculating the metrics and the correct data should be available within 1-2 days.

CMS Service

It is a slow start of CRUZET-4 atm (day-1 today). HCAL and DT are in, Tracker may join in the afternoon. DAQ currently is addressing some issues seen. From the computing standpoint, we have regular data operations shifts in place and operational - focusing mostly on T0 workflows - and we are using the CRUZET-4 exercise to implement the general computing shift design put in place recently, which is supposed to complement and integrate the DataOps approach and extend it to monitor the overall infrastructure, interfacing with the Grid Ops and the distributed facilities.
Summer08 production
More details will follow from DataOps team. Anyway, the most urgent and needed info by T1 sites has been already provided to them at the end of last week (they need it to prepare tape families on their MSS systems); current storage needs estimated to be as follows:
  • ASGC: 27.0 TB (RAW) + 13.5 TB (RECO) = 40.5 TB
  • CNAF: 26.5 TB (RAW) + 13.25 TB (RECO) = 39.75 TB
  • FNAL: 64.6 TB (RAW) + 32.3 TB (RECO) = 96.9 TB
  • FZK: 58.8 TB (RAW) + 29.4 TB (RECO) = 88.2 TB
  • IN2P3: 22.0 TB (RAW) + 11.0 TB (RECO) = 33.0 TB
  • PIC: 8.4 TB (RAW) + 4.2 TB (RECO) = 12.6 TB
  • RAL: 23.9 TB (RAW) + 11.95 TB (RECO) = 35.85 TB
