Not sure if this was planned or not, but we see around 200 cms transfers of 2.5Gb or so files from a single disk server (mainly because the CMS pool at Glasgow isn't that many disk servers, as most of our space goes to ATLAS). They're all called things like LoadTest07_T3_UK_ScotGrid_GLA_CF.183052630.0 and were written some time in early 2014 if it helps.
