Abstract
The paper presents a system for estimating the access time for data stored on the CASTOR Hierarchical Storage Management (HSM) system developed at CERN. The estimation is based on the gray-box approach. The system consists of two modules: Monitor and Simulator. Information about the current state of the HSM system is obtained by the Monitor via CASTOR API functions. The second module is based on event driven simulation of the HSM system. Special attention to the queuing algorithm is paid. Implementation details and tests results are presented.
