SAMGrid Integration of SRMs

SAMGrid is the shared data handling framework of the two large Fermilab Run II collider experiments: DZero and CDF. In production since 1999 at D0, and going into pro-duction at CDF, the SAMGrid framework has been adapted over time to accommodate a variety of storage solutions and configurations, as well as the differing data process-ing models of these two experiments. This has been very successful for both experiments. Backed by primary data repositories of approximately 1 PB in size for each exper-iment, the SAMGrid framework delivers over 100 TB/day to DZero and CDF analyses at Fermilab and around the world. Each of the storage systems used with SAMGrid, however, has distinct interfaces, protocols, and behaviors. This led to different levels of integration of the various stor
