On the 16th of September 2000, at the Computer User Committee at DESY, a new project, A Homogeneous Distributed Storage Environment for Physics Data Processing, was presented. Its main objectives were to address storage system concerns after HERA and Tevatron accelerator upgrades at DESY and Fermilab. The new system had the following goals:
Optimized usage of existing tape drives due to transfer rate adaption. Possible usage of slower and cheaper drive technology without overall performance reduction.
