A Scale Test of Experiment Production (STEP'09) is being executed in June 2009. This full production activity will stress a number of critical areas, including tape writing / reading at Tier1s (and Tier0) as well as analysis. The main period of STEP'09 is the first two weeks of June, with a post-mortem workshop to be held early July.
The most likely outcome of this exercise is that there will be a number of areas where limitations are found. This session will focus on the post-STEP'09 activities and improvements, defining the 'final' WLCG operations environment that will be used for the first pp run of the LHC.
