PREDICTING HARDWARE FAILURES IN A SERVER

摘要

A computer system is monitored for conditions bearing on the effective age of various hardware components of the system. Upon detecting an age adjustment condition, the affected hardware components are identified. An age adjustment is determined for each of the affected hardware components. The adjusted age is stored for reference when taking actions based on the adjusted age, such a component replacement and/or workload placement.

主权项

1. A method for estimating a remaining life expectancy value for hardware components used in a computing system, the method comprising:
detecting an age adjustment condition during an operation of the computing system; determining a set of hardware components in the computing system, each hardware component having a corresponding current life expectancy value affected by the age adjustment condition; adjusting the corresponding current life expectancy value of each hardware component in the set of hardware components to a reduced life expectancy value based on the age adjustment condition; and generating a health report for a first hardware component in the set of hardware components, wherein: the age adjustment condition is a service action performed on a first hardware component; the set of hardware components includes at least a second hardware component; the service action is a member of the group consisting of:
power supply changes,removal of the first hardware component,installation of the first hardware component,power resets,misconfiguration of the first hardware component,improper seating of the first hardware component,improper cabling,hot reboots,error injections, andrepair of the first hardware component; and at least the determining and adjusting steps are performed by computer software running on computer hardware.
