Abstract

A method for generating a service action for a computer system is described. During the method, a longevity index value for a packaging technology in the computer system is calculated using a longevity model and thermal and vibration telemetry data that is collected in the computer system. This longevity model may be based on accelerated failure testing of the packaging technology, field failures of the packaging technology in a group of computer systems that includes the computer system, and/or thermal and vibration telemetry data for the group of computer systems. Furthermore, using the longevity index value, the service action for the computer system is determined. Based on the longevity index value, remedial as action, e.g., repairs to the computer system, may be scheduled and performed.

Claims21

Dependent claims

A computer-implemented method for generating a service action for a computer system in a group of computer systems, comprising:

in at least one computer, performing operations for:
receiving telemetry data for the computer system that is collected during operation of the computer system, wherein the telemetry data includes temperature measurements and vibration level measurements in the computer system;
receiving a first longevity model that predicts longevity of a packaging technology used in the group of computer systems, wherein the first longevity model is based on vibration and thermal testing data for the packaging technology that was collected before the operation of the computer system;
determining a current longevity model for the packaging technology based on the first longevity model and the telemetry data;
using the current longevity model and the telemetry data to calculate a current longevity index value for the computer system, wherein the current longevity index value provides an estimate for the longevity of the packaging technology used in the computer system;
and
using the current longevity index value to cause the service action for the computer system to be generated.
