To distribute computing for CDF (Collider Detector at Fermilab) a system managing local compute and storage resources is needed. For this purpose CDF will use the DCAF (Decentralized CDF Analysis Farms) system which is already at Fermilab. DCAF has to work with the data handling system SAM (Sequential Access to data via Metadata). However, both DCAF and SAM are mature systems which have not yet been used in combination, and on top of this DCAF has only been installed at Fermilab and not on local sites. Therefore tests of the systems are necessary to test the interplay of the data handling with the farms, the behaviour of the off-site DCAFs and the user friendliness of the whole system. The tests are focussed on the main tasks of the DCAFs, like Monte Carlo generation and stores, as well as the readout of data files and connected data handling. To achieve user friendliness the SAM station environment has to be common to all stations and adaptations to the environment have to be made.
