Job migration in response to loss or degradation of a semi-redundant component

Abstract

A computer program product and method of managing the workload in a computer system having one or more semi-redundant hardware components are provided. The method comprises detecting loss or degradation of the level of performance of one or more of the semi-redundant hardware components, identifying hardware components that are affected by the loss or degradation of the one or more semi-redundant components, migrating a critical job from an affected hardware component to an unaffected hardware component, and performing less-critical jobs on an affected hardware component. Loss or degradation of the semi-redundant component reduces the capacity of affected hardware components in the computer system without entirely disabling the computer system. Jobs identified as being critical are run on hardware components having the most capacity and reliability, while allowing less-critical jobs to make use of the remaining capacity of affected hardware components. Optionally, the semi-redundant hardware component may be selected from a memory module, CPU core, Ethernet port, power supply, fan, disk drive, and an input output port.
