A computer program product includes computer usable program code embodied on a computer usable storage medium for performing a 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. 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.
