Apparatus and method for managing part life in a datacenter
An information handling system includes a component and a component life manager. The component provides error indications associated with aging of the component, and has a predefined error threshold and a predefined warranty duration. The component life manager receives the error indications, fits the received error indications to a curve, determines an end of life estimate based upon the curve and the error threshold, determines an end of life date based upon the end of life estimate and a date that the first error indication is received, determines a loss of life based on the end of life estimate and the warranty duration, and determines a component life score for the component.
