【 摘 要 】

Changes in experiment data models are having a significant impact on the operations of the Tier 1's within WLCG. In this paper we look at how two sites, ASGC and RAL, have evolved to meet the specific request to separate the tape and disk systems for user jobs. We discuss the solutions chosen at the two sites, why the decisions were made and discuss the work required to implement, migrate to and support these solutions.
