Hi Ralf, thanks for the response, Tuning it down to 3+3 (from the original 6+6) seems to alleviate but not solve the problem completely. I totaly agree with your suggestion, from this point onwards it seems to be a case of finding a spooling setup with enough I/O oomph. One question however, in your setup you have limited your concurrent jobs to 3 as in 3 jobs overall or as in 3 jobs per drive (9 overall)?
