1. More FAX dress rehearsal ideas & proposed plan R. Gardner 12/3/12

2. ?? First users Recall roadmap …more dCachedev …new monitoring stream & integration issues IT Sites As always, the docs could Be better

3. Towards ‘production readiness’ & usability • While there has been at-large use of the FAX infrastructure, and interest for tutorials, to get to a production quality infrastructure which guarantees a good user experience we have some more work to do. • Early adopter feedback • Seehttps://twiki.cern.ch/twiki/bin/viewauth/Atlas/SoftwareTutorialAnalyzingD3PDsInROOT • Main issues: • Dataset availability via FAX • Uneven performance from redirectors and sites

4. From last time: • Define an FDR sufficient to cover most anticipated user workloads, including user docs • Define a rehearsal period: ~ week and metrics (and needed monitoring) • Poll for site volunteers and an ad-hoc FAX OPS team • Execute the FDR; gather monitoring statistics and accounting data • Propose spend December preparing • Identifying five exemplar use cases that can be run by FAX OPS team • Preparing a clean set of tutorial-like documents • Preplace example datasets • Load test redirectors and sites against with examples • Solve the main problem of federated access to datasets • Week of January 21 going live with real users
