Abstract: A highly available multi-node computer system is operated by monitoring the aging and usage of a plurality of hardware components that are part of the system's networked nodes. While monitoring the components, a determination is made that one of the components has aged, worn, or both, to a level that is selected as being close enough to the component's predicted end of life in the system so as to prevent failure of the component in the system. A notification is sent to replace the component, in response to the determination. Other embodiments are also described and claimed.
