Abstract
The computer availability is predicted by determining a hazard fail rate for the computer system that is based on the hazard fail rate of the individual computer components and the computer system structure s6, as well as the mean repair rate for the system. The computer hazard rates of individual computer system components are based on the error monitoring of those computer components during the computer system operation in real time.
Claims16
A method of predicting availability of a system, the system comprising a plurality of components, the method comprising:
- determining a hazard rate for the system;
- determining a mean repair rate for the system;
- and
- calculating the system availability from the system hazard rate and the system mean repair rate.
Apparatus for maintaining a system at a predetermined service level, comprising:
- means for monitoring the system for errors;
- means for predicting availability of the system based on the errors;
- and
- means for acting in response to the predicted availability to maintain the system at the predetermined service level.
