Abstract

A technique is described whereby testing routines, used in establishing reliability, availability and serviceability (RAS) criteria, as used in high performance computer systems, are controlled and measured so as to optimize the tests and the time required to run the tests. Also, the concept reduces the time involved in generating the data required to write maintenance assurance tests (MATs) and basic assurance tests (BATs). The technique attempts to provide a maintenance package with the following RAS criteria: -Error detection of 95% of all hardware failures. - Isolation of a field replaceable unit (FRU) failure with a 90% effectiveness. - Establish an average repair time of one-half hour, with a maximum repair time of 1.4 hours. - Provide concurrent diagnostic capability.
