To get large disk-like characteristics and offset the significant power demands of hard disk drives, we propose a fully functional hybrid archive system (called Pseudodisk) composed of an array of disks and a tape library. To get an energy conservation, low cost archive system, Pseudodisk uses data value model and utility function to guild data management. Two novel algorithms are proposed for data placement and data migration, which are referred to as utility-based data placement (UDP) and and system utility percentage (SUP) algorithms respectively. To validate the efficiency of the proposed archive system, we conduct the performance evaluation and the power-saving simulation.
