Abstract : This Fail-Safe Technology Report includes the results of a feasibility study, preliminary design and recommendations for subsequent work. Fault tolerance is the unique attribute of a computer system that enables that system to continue its program-specified behavior in spite of the occurrence of faults. This feature is essential and cost-effective in applications where computer failure causes human injury or loss of critical data or equipment. For less critical applications, inclusion of fault detection and diagnostic procedures within the computer itself greatly increases repair time with a concomitant reduction in maintenance cost and downtime. Included in this report are discussions of the applications, tradeoffs and requirements that led to the suggested architecture. An Executive Summary in Section 3 outlines the results of these discussions. The preliminary suggested hardware and software design is then shown. Specific recommendations for direction of further productive efforts are also included in this report. An overview of the state-of-the-art concepts and techniques employed in fault tolerant computer designs is added as Appendix I.
