Description
CDF is an experiment at the Tevatron at Fermilab. One dominating
factor of the experiments' computing model is the high volume of raw,
reconstructed and generated data. The distributed data handling
services within SAM move these data to physics analysis
applications. The SAM system was already in use at the D-Zero
experiment. Due to difference in the computing model of the two
experiments some aspects of the SAM system had to be adapted. We will
present experiences from the adaptation and the deployment phase. This
includes the behavior of the SAM system on batch systems of very
different sizes and type as well as the interaction between the
datahandling and the storage systems, ranging from disk pools to tape
systems. In particular we will cover the problems faced on large scale
compute farms. To accommodate the needs of Grid computing, CDF deployed
installations consisting of SAM for datahandling and CAF for high
throughput batch processing. The CDF experiment already had experiences
with the CAF system. We will report on the deployment of the combined
system.
