The purpose of the paper is to carry out Cost-Analysis of a computer system of two identical units. Each unit comprises hardware and software components which may fail completely directly from normal mode. There is a single server who inspects the unit at its hardware failure to see the feasibility of repair. If repair of the hardware components in the unit is not feasible, the components are replaced by similar new one with some replacement time. However, only replacement of the software components in the unit by new one is made at their failure with some replacement time.
