  • Patent number: 11201805
    Abstract: In embodiments, methods and systems for implementing an infrastructure management system that supports hardware failure remediation are provided. A determination is made that a failure of a hardware component has occurred. The hardware component is part of a hardware composite. A remediation attribute of the hardware composite is accessed. The remediation attribute indicates a minimum operational bar for the hardware composite. The minimum operational bar is based on health metrics or optional and required components of the hardware composite. The bar supports determining whether the hardware composite should operate in a degraded state. A determination is made that the hardware composite if operating without the hardware component that has failed meets the minimum operational bar for the hardware composite. Operation of the hardware composite in the degraded state is initiated.
