1. CMS Physics Association Tier-2 is associated to one or several physics groups Vienna is associated to SUSY and b Tag An association is connected with responsibilities Currently only Diskspace requirements are given Diskspace requirements 50 TB central (2011 → 100 TB) 50 TB per group (2011 → 75 TB) Local user space (not enforced) Sites below 200 TB (240 TB) will loose their MOA credit

4. New association Its hard to say what new association we would get SUSY has strong sites in Europe and US Aachen, Imperial, Florida Btag only in the US Nebraska One should not forget that an increase of Diskspace needs also more computing capacities Do we have now enough ?
