Abstract

A computer condition detection system for detecting conditions of computer components to predict a failure. Conditions on computer components may be detected by a health computer coupled to a main computer (e.g., a computer blade). The health computer may be coupled to sensors on various computer components for detecting conditions such as temperature, airflow velocity, voltage, and current. The health computer may be coupled to an independent health network and may be powered by a separate power supply than the main computer power supply to detect problems even if the main computer fails. The main computer may also be coupled to the sensors to detect conditions on the main computer'"'"'s components. If a condition is detected that meets a predetermined criterion, corrective or preparative actions may be taken. For example, data on the main computer may be backed up in anticipation of a main computer failure.

Claims
